Balancing Power Availability With Sustainability – DG PV Controller

A DG-PV Controller 

Frequent power cuts are a grim reality faced by all industries and commercial establishments across the country. It forces businesses to rely on Diesel Gensets, thereby increasing costs as well as the carbon footprint of the organisation.

The effectiveness of generating clean and cheap power by installing GRID connected rooftop solar power plant gets marred by frequent power cuts as solar power plants use grid power for reference voltage and frequency. In the absence of grid power, the system is unable to function, causing dual loss to the owner. The owner not only loses the electricity that could have been generated by rooftop solar power plant but is also compelled to switch over to the costly DG set for full power back up.

DG-PV System controller is a unique solution that resolves this problem by interfacing with the grid and DG set simultaneously to provide a complete grid management solution. This controller makes it possible to use solar power even when grid power is not available, by using a diesel generator. It ensures maximum utilisation of solar power and minimum fuel consumption by DG set.

Smart communication between the photovoltaic system and DG set assures greater uptime of the system and up to 25-30% fuel saving with maximum grid stability.

A solar DG-PV controller automatically synchronises solar PV with DG set. All information related to grid properties, load requirement and minimum genset loading is considered while configuring the fuel saving controller, which defines the optimum PV power set point for secure and reliable operation at all times.

The fuel save controller enables the hybrid controller system to meet any dynamic load requirement. If required, the PV power can be throttled down to guarantee smooth genset operation for optimum grid stability.

Some of the other benefits of DG-PV controller are protection against reverse power current and dynamic monitoring of system parameters on the SCADA /monitoring software. Also, it will ensure zero power flow from PV to grid in case the load demand comes down, thereby maintaining system stability when running PV plant with DG generator in the absence of the grid. 

The hybrid control system is highly scalable and can be adapted to the specific requirement of the application, for example – communication with inverter over ethernet or serial (RS485/232), universal analog inputs/output module, thermocouple and RTD. The controller also ensures compatibility with all makes of solar inverters and diesel generators.

Thermax has set up DG PV controller for multiple customers over the years. Our experts can guide you to select a configuration that works best for your plant. As the world moves towards improving energy efficiency and conserving resources, DG PV controller can help in taking another step towards sustainability and reduce your cost of operation in the process.

Thermax’s digitalisation wave: Solutions for today and tomorrow

The scenario

Digital transformation has occupied the centre stage in the recent past and has started reshaping the way manufacturing sector works. The recent wave of lockdowns that followed the COVID outbreak accelerated the pace of digital transformation. Some enterprises were prepared on how to deal with it, some learnt it on the go, and some are still learning.

As a key enabler of our growth ambitions and vision of becoming a high performance global organisation, we at Thermax commenced our ‘Smart journey’ with a structured digital roadmap. We have been progressively adopting digital tools to improve our business efficiency, adapt to a more agile and connected way of working; all this is backed by strong data security. Our digital transformation journey consists of three pillars – from individualistic to collaborative for the organisation, from people-driven to industry benchmarked processes and from a product-based approach to outcome-oriented solutions for customers to ensure precision, reliability and consistency.

Manufacturing competitiveness

The first major milestone in the journey was the commissioning of a state-of-the-art manufacturing facility at Sri City, Andhra Pradesh for manufacturing high efficiency vapour absorption chillers for global markets. The factory deploys high level of automation, a first of a kind for a capital goods company, equipped with an automated MES (Manufacturing Execution System) and skilled workforce on the shop floor.


Employee collaboration

We aim to adopt contemporary practices that can integrate all operations and transform business processes into more strategic and measurable ones. The HR team at Thermax launched SAP SuccessFactors, which is an industry-leading cloud human capital management (HCM) suite that uses advanced technologies and helps in managing various facets of employees’ organisational lifecycle. This covers core HR and payroll, attendance management and time logs, performance and appraisals, recruitment and onboarding, learning and development; with a focus on people engagement and experience. 

Digitalisation is also keeping finances in order, which is another daunting task. Now imagine, for claiming expenses you have to fill a form, get it approved by your manager and then collate all the physical copies of the bills and submit them to your finance team. Isn’t a tedious task? With the help of SAP Concur, 

claiming paperless expense has become so much easier and productive for employees, managers and the finance team.

The latest addition to the digital platform is THERMSafe, which was launched during the ongoing pandemic crisis. It is an app developed in-house to capture the health status of employees while they are working from home and before entering the office premises. The advanced feature in the application prompts users to be self-quarantined if needed and also update them on sanitisation status being followed at office premises and common areas. 

Customer engagement

Thermax has been leveraging digitalisation to make the company more efficient; moreover enhance the value of our offerings for our customers. Recently, Thermax commissioned a large auxiliary boiler online for a customer in Egypt with the help of various tools, including TeamViewer, Microsoft Teams, Grafana Portal, among others, that enabled real-time collaboration between two teams located in different countries. 

According to a study by Gartner, the IoT market will grow to 5.8 billion in 2020. Like other companies, Thermax is also exploring ways in which it can inculcate IoT enabled solutions in its business offerings. Thermax’s industrial analytics solution provider, Ultramind, is IoT enabled and can be integrated with boilers and heaters that has PLC systems of any make. It identifies gaps in operating parameters, analyse factors and make necessary recommendations to improve combustion and heat transfer processes. The tool is a great value addition for customers in terms of improving efficiency, safety standards, seamless maintenance, and critical spare parts planning.

Thermax’s Remote Online System Support (ROSS) is a cloud-based remote monitoring technology, which monitors and controls the performance of absorption chillers across the globe, thus offering better customer service and chiller maintenance remotely. The advanced feature supports in managing and monitoring the chillers with alarms, trend graphs, and reports efficiently. ROSS is now connected to around 547 chillers across the globe. 

Concurrent to improving customer facing application, Thermax is also enhancing its internal processes to provide the best quality output to its customers. We have deployed a robust automated proposal generation process, addressing customer requirements accurately with the shorter response time. The digital engineer-to-order process supports advanced engineering calculations and functions and seamlessly integrates design softwares with customer needs to streamline the automatic generation of technical proposals, engineering drawings and BOQs.

Through our digitalisation initiatives, our endeavour is to create a connected ecosystem where we engage our customers seamlessly and provide better customer experience, regardless of time and place.

More power from the Sun – Designing solar plants for maximum generation

Solar sector in India has seen tremendous growth in a short period of time. As we work to scale up our solar PV generation capacity, equal efforts have to be made to ensure the equipment quality of upcoming installations is up to industry standards. The plants must strictly adhere to established norms of engineering, safety and their seamless integration into the national grid. Precise design and engineering of solar power plants in a way that optimises power generation is essential to harness its real benefits.   

While designing a solar PV system, it is crucial to have a thorough understanding of parameters that affect power generation comprising both metrological data and electrical components. Solar power plant design calls for high technical proficiency in order to maintain a delicate balance between performance and cost. Various factors such as infrastructure, solar plant layout, technology selection, system configuration, and quality of the components play a very important role in maximising energy yield and minimising project cost.

A key input for a solar PV power plant design is the metrological data of the installation site, which consist of solar irradiance, temperature, relative humidity and wind data. It is critical to consider updated metrological data base and advanced software to predict expected power generation with high precision.

The basic components of a solar power plant include a solar module, inverter electronics, structures and balance of electrical system.

The electrical components are primarily classified into DC side and AC side. DC side covers solar modules, solar cables inverter, and mounting system, while the AC side entails AC cables, electrical protection, transformer and evacuation. Additionally monitoring system (SCADA/data logger/cloud-based system) is used for tracking and predicting power generation, capturing plant performance and O&M. 

Solar technology has witnessed innovation at a feverish pace in the last decade, thereby progressively improving solar module efficiency and sizes. Modules are now available at higher power wattage and higher voltage. With this incremental system voltage, it is possible to reduce the solar field losses up to some extent which ultimately increases the plant performance ratio (PR). Modules being at the core of power generation must be selected with meticulous evaluation of all relevant parameters. It should be safe for the user, O&M team and the system. Alongside, it must necessarily address UV rays and other environmental related conditions.  

Inverters should be of good quality, with high conversion efficiency, and proven reference base that has good online and offline service support across the country. The replacement parts should be easily available. The inverter should have adequate protection features on both DC and AC side along with flexibility in design. Adaptability to environmental conditions of the solar field is a very critical factor too.

Other components should be selected as per site condition and project requirement. Importantly, valid and applicable certifications should be available for all components to meet necessary quality standards.  Certifications are also required for government approval, insurance claim and safe operation of the plant. 

An optimally designed plant should have average first year PR between 78% to 82% depending on various aforesaid parameters, losses and  proper O&M. To optimise for maximum generation we need to take into consideration various loss parameters mentioned below :

Sr. no Loss Parameter Typical Values (in %)
1 Shading  Not greater than 3.5%
2 Incidence Angle Modifier  Not greater than 3.5%
3 Soiling Loss  Not greater than 3.5%
4 Module Temperature Loss  Approximately 11-12%
5 Module Quality Loss  Typically this ranges from 0 to 3%
6 First Year Module Degradation (under Light
Induced Degradation (LID)
 LID – Typically this ranges from 0 to 3%

Annual Degradation – Typically this ranges from 0.5% to 0.75%

7 Module Array Mismatch Loss  Typically 1.2%
8 DC Ohmic Wiring Loss  Not more than 3.5%
9 Inverter Loss during Operation (Efficiency)  Typically 2.5%
10 AC Ohmic Losses  Not more than 3.5%
11 System Unavailability  Typically 1%
12 External Transformer Loss  Typically 3%


Solar PV installations are often perceived to be relatively simple. But sans proper design, installation and regular maintenance, not only does the desired power generation suffer, but safety of the electrical system could also be compromised leading to fatalities. Hence, due care and attention are to be extended to all facets of a solar plant.

While most of the solar players and media continue to focus on the cost of solar, a prudent customer needs to look at the performance track record while choosing the EPC partner for their solar project. Since a solar power plant has an expected life of 25 years or more, degradation of performance over time has an outsized impact on overall returns to the customer. 

Thermax has installed more than 130 solar PV plants spread over 70 cities across 18 states. It is a testimony to our engineering capability and rigorous focus on quality that all our installations continue to operate above-committed performance ratio. We have managed to reach PR as high as 85%-86% for some installations with an intelligent combination of site conditions and technical innovation. Combined with our O&M support, customers can be rest assured that their plant will continue to generate green solar power for its useful life and beyond.

Safety starts with the right attitude and behaviour

Every year March 4th is celebrated as National Safety Day commemorating the Foundation Day of the National Safety Council and the first National Safety Day (NSD) Campaign which was launched in 1972.
The campaign now entering its 45th year, has grown into a major national campaign widely celebrated by industries, trade unions, government departments, regulatory agencies NGO’s and institutions with the active support of the Central and State Governments and media. It has made an impact on the industrial scenario at the national level by contributing to increased safety awareness and reduction in accidents. Started for a single day on March 4th as NSD, the campaign is now being spread over a week from March 4-11. Today, March 4, 2016 marks the 45th National Safety Day.

As safety is a top priority at Thermax, we look forward to this day each year as an added springboard for how we work all year round towards our goal of zero accidents and a healthy work environment.

Theme for 2016:


Hazards at Work
Whatever sort of business you are, there is always the possibility of an accident or damage to someone’s health. All work exposes people to hazards, be it: loads which have to be manually handled; dangerous machinery; toxic substances; electricity; working with display screen equipment or even psychological hazards such as stress.

Preventing accidents and health damage

The underlying aim of good health and safety management is to make sure that people’s safety is not put at risk and that their health is not damaged Remember, no job is important that we can’t take time to perform it safely.

Attention to health and safety is not just about obeying the law and being socially responsible. It also makes good business sense.

Safety practices can:

  • reduce your accident losses;
  • cut absenteeism;
  • help you become more efficient; and
  • improve your business profile with customers, clients, insurers, enforcers etc.

The key to ensuring the safety and health of young people in the workplace is having a good health and safety management system which protects everyone. But young people can be at particular risk because they lack experience and trained judgement and thus they need good advice, information and supervision.

Working Together
Remember, you cannot achieve a safe and healthy working environment on your own. It has to be a team effort. You need to get proper health and safety co-ordination going with other businesses with which you come into contact such as clients, customers, suppliers or contractors. Don’t wait for things to go wrong and then go for the ‘quick fix’. Build health and safety in from the start. Don’t delay – make time and space to get started today!

Why vapour absorption technology is the way forward?

In an era of heightened awareness of energy efficiency and the associated environmental impacts, many industries worldwide are exploring environment friendly technologies that provide equivalent or improved performance while reducing or eliminating harmful side-effects. The refrigeration and air-conditioning industry, due to its reliance on CFCs and HCFs, has invested in research in alternatives to the industry standard vapour compression machines.

One alternative technology with great promise is vapour absorption technology. Absorption chillers offer comparable refrigeration output with reduced SO2, CO2, and NOx emissions. Absorption chillers do not use CFCs or HCFCs, refrigerants that contribute to ozone depletion and global warming.

Additionally, gas-fired absorption chillers can save significant amounts in energy costs when used in combination with a vapor compression chiller in a hybrid system. The hybrid system can take advantage of the comparatively low price of natural gas (per unit ton) and rely on the high performance of vapor compression when electricity prices are lower.

Understanding Vapour Absorption Technology

One of the oldest methods to mechanically cool a space is with absorption technology. Vapour Absorption Technology is an alternative cooling technology that saves money and reduces the environmental impact of your cooling solution.

Unlike conventional electricity driven Compression machines, Vapour Absorption Machines (VAMs) are driven by waste heat sources like Steam, hot water, natural gas, fuel oils, Agro waste and other similar fuels.

Since heat is the source of energy, operating cost of VAMs is minimal making it more suitable for industrial usage.

Benefits of using Vapour Absorption Technology

The benefits of encouraging potential consumers to install absorption chillers for their chilled water and air conditioning requirements are two-fold.

Firstly, absorption systems use no CFCs or HFCs, so are environmentally friendly; secondly they have very few moving parts and are consequently relatively easy to maintain.

Thermax Profetherm promotes Vapour Absorption Machines as a cost effective and environment friendly alternative to electricity driven compression chillers.

How do absorption chillers work?

Curious to know how an absorption chiller works? Don’t worry we’ve got you covered.

For beginners, an absorption chiller is a closed loop cycle that uses waste heat to provide cooling or refrigeration.

This absorption cooling cycle relies on three basic principles:

  • When a liquid is heated it boils (vaporizes) and when a gas is cooled it condenses
  • Lowering the pressure above a liquid reduces its boiling point
  • Heat flows from warmer to cooler surfaces.

The process of absorption cooling is dependent on a thermochemical ‘compressor’. Two different fluids are used: a refrigerant and an absorbent. The fluids have high “affinity” for each other, which means one dissolves easily in the other.In a water-lithium bromide vapour absorption refrigeration system, water is used as the refrigerant while lithium bromide (Li Br) is used as the absorbent. In the absorber, the lithium bromide absorbs the water refrigerant, creating a solution of water and lithium bromide.

The refrigerant—usually water—can change phase easily between liquid and vapour and circulates through the system.

Heat from natural gas combustion or a waste-heat source drives the process. The high affinity of the refrigerant for the absorbent (usually lithium bromide or ammonia) causes the refrigerant to boil at a lower temperature and pressure than it normally would and transfers heat from one place to another.


Boiling point of the water acts as a function of pressure. At atmospheric pressure, water boils at 100 deg. C. When maintained at high vacuum, water will boil and sub-cool itself. The boiling point of the water at 6 mm-Hg (abs) is 3.7 deg.C.


Lithium Bromide (LiBr) has the property to absorb water (Refrigerant) due to its chemical affinity. It is directly proportional to concentration and inversely proportional to its temperature.


Diluted LiBr loses its capacity to absorb water vapour. Thus, needs to be re-concentrated using a Heat Source. Heating may be in the form of Steam / Flue gases / Hot water /fuel firing.


The heating causes the solution to release the absorbed refrigerant in the form of vapour. This vapour is cooled in a separate chamber to become liquid Refrigerant.

Solar power plant installations: Lease with ease

Rooftop solar PV installations have seen tremendous growth over the last decade. Improvement in module efficiency and falling costs year on year have made setting up of solar PV plants an attractive proposition. High electricity tariffs charged by the DISCOMs and unreliable power supply have provided further impetus to organisations deciding to generate their own power. Also, with the signing of the Paris Climate accord, a lot of organisations have decided to move towards sustainable business practices, thereby creating demand for renewable solar power.

The installed capacity of rooftop solar power plants in India is estimated to be approx. 6,000 MW. Industrial and commercial customers have been at the forefront of setting up solar power plant for captive consumption accounting for more than 67% of the installed base. Since electricity cost comprises a major expense for both industries and commercial establishments, replacing costly grid power by investing in rooftop solar system helps them in improving competitiveness and profitability. A healthy payback of 3-3.5 years on an average with lower LCOE (Levelised Cost of Energy) has increasingly made setting up solar power plant for captive consumption an obvious choice for most companies.

While there are many existing models to finance your plant, investing in your own solar power plant ensures maximum benefits. The plant not only generates free power for 25 years, but you can also gain by claiming accelerated depreciation and reducing your carbon footprint, besides meeting RPO obligation through solar power.

However, it might not always be possible to allocate capital for investing in solar power plant. For example, in the current situation with organisations reeling under the impact of COVID-19, preserving capital has taken precedence over investing in projects. Sometimes the constraints might be on obtaining bank financing, or the customer might have other investment opportunities or capex requirements in their core business which needs to be prioritised.

Leasing provides a perfect solution for gaining most of the benefits of self-financing with little upfront investment. In this model, the customer obtains the rooftop solar system on lease from a financing partner by agreeing for a down payment (typically 15%-20%) and an agreed lease rental for a fixed period (up to 60 months). The monthly rentals are worked out such that the electricity cost saved is higher than the lease payment, thereby ensuring net savings. During the lease period, the customer is also able to gain tax benefit by accounting for lease payments as an expense. Also, leasing does not lead to an increase in liability as the asset stays off the balance sheet of customers. The project and performance risks are borne by the EPC partner on whom the financing company places a turnkey order. At the end of the lease period, the customer has the option to purchase the investment at the residual value and enjoy free solar power for the remaining 20+ years.

Thermax has executed multiple projects for its customers under the leasing model. We have pre- approved tie-ups with reputed financial partners to make it a seamless experience for customers. Once the customer chooses to go for leasing, Thermax brings on board the financial partner who then conducts the necessary due diligence. Once approved, an EPC order is placed on Thermax to set up the solar power plant with agreed specifications and timelines. The entire process is managed with minimal paperwork and on an average takes less than 3-4 weeks from application to order placement. Following are some examples of our successful installations through leasing model:

1. 1,000 KWp solar power plant for footwear manufacturer
2. 742 kWp rooftop solar plant for a leading sports company
3. 500 kWp rooftop solar plant for food & packaging company
4. 250 KWp solar power plant for a leading food processing company

Preventive care: nitrogen blanketing

One of the most important aspects of preventive care in absorption chillers is ‘preservation’. This is ignored many times resulting in frequent issues due to corrosion, loss of efficiency and shortening of the service life of the equipment.

The most critical breakdown in a chiller apart from component failure occurs when the vacuum breaks either due to tube ruptures, leaks or if there is any physical reason for ingress of air in the machine such as leaks through the service valves or gland, leaving the purge valves open allowing air to enter the chiller or leaving the machine open during any repair or maintenance work.

As Lithium Bromide (LiBr) is highly corrosive in the presence of atmospheric oxygen, the corrosion process starts. It is therefore important that in such situations quick actions are initiated to seal off the leaks temporarily and keep the machine under an inert nitrogen atmosphere until a permanent action is initiated.

One of the common mistakes most technicians do after sealing off the leaks in the tubes or welding of the chiller is that they quickly charge nitrogen in the machine and declare that the machine is safe under preservation.

This should be strictly avoided as there is atmospheric air already present inside the chiller. This is because during the leak either air or water containing atmospheric oxygen enters the chiller through the leaking area and gets trapped in the chiller. It is therefore important to realise this fact.

Charging the machine with nitrogen only increases the pressure of the air inside the shell. Since this trapped air inside the chiller shell contains oxygen, the process of corrosion gets initiated. Hence in such situations it is extremely important that only after the leaking areas are sealed off with reasonable strength such as plugging, welding etc. that a vacuum is created in the machine by running the vacuum pump and pulling out all the entrapped air.

On reaching this attainable vacuum,(refer chart for attainable vacuum to be pulled w.r.t the ambient temp prevalent at the time of purging) the chiller should be kept under the vacuum hold test for at least 12 hours and checked for vacuum drop. In case a drop in vacuum is observed, the chiller should be rechecked for leaks and such leak should be attended and the process repeated till the attainable vacuum and vacuum hold test is achieved.

Only then should the machine be charged with nitrogen so that the gas fills up the entire shell and an inert nitrogen atmosphere is achieved. At no point should the chiller be left unattended allowing air to stay for long inside the chiller. This is also applicable for any normal long or short duration shutdowns when the chiller is taken out of service. A proper de-commissioning procedure should be performed to ensure trouble-free operation and longer life of the equipment.

All you need to know about the absorption chiller market

Absorption chillers are a type of refrigerant. It contains lithium bromide-water (LiBr/H2O) and ammonia-water as a main constituent for refrigeration application. Unlike conventional compression chillers, absorption chillers utilize heat energy for cooling purpose rather than mechanical energy. One of the simplest applications of absorption chillers is found in residential refrigerators, which contains a gas flame at the bottom of the machine, and an ice cubes at the top of the machine and there is no electricity involved in whole refrigeration cycle. However an absorption chiller used in commercial and industrial refrigeration much larger in size and more complicated in terms of design technology, but the basic operating principle remains the same. Some of the major components of an absorption chiller arrangement include generator, evaporator, condenser, and the absorber. Some of the major end user application of absorption chillers is found in refrigeration, oil and petroleum industry, chemical industry, geothermal appliances, freezing and food canning.

Globally, on the basis of the product, the absorption chiller market can be broadly classified as exhaust gas (multi energy) chillers, hot water fired chillers, steam Fired Chillers and Natural gas fired Chillers.

On the basis of various design technology involved the absorption chillers market can broadly categorized as single effect absorption chillers, double effect absorption chillers and Triple Effect absorption chillers. Single-effect absorption chillers design technology is the most widely used since it have coefficient of powers (COP) in range of 0.6 to 0.8 out of an ideal 1.0. Single effect absorption chillers are used in various industries such power plants and boilers.

The global absorption chillers market is driven by the various cost and performance benefits associated with it. The use of gas based cooling system provides lower operating cost by avoiding peak electric demand charges. Moreover absorption chillers offer quiet and vibration-free operation of refrigerator, improved system efficiency and reliability, and lower maintenance cost over long run.

The high initial cost of absorption chillers over some of other conventional compression chillers is one of the major restrain of the market predominantly within the context of cost conscious consumers of developing economies.

North America is the largest market of absorption chillers followed by Europe and Asia Pacific. The high concentration of allied industries such chemicals, petroleum, and processed food in North America is one of the key factor contributing to the dominance for absorption chillers market in this region. Asia Pacific is the fasted growing market of absorption chillers followed of Rest of the World (RoW) which includes Middle East, Latin America and South Africa. The rising market of absorption chillers in Asia Pacific is mainly fueled by the increasing demand from the emerging economies such as India and China. Moreover the shortage of electricity and lack of proper electrical distribution infrastructure in developing countries is further helping in adoption of energy efficient appliances in this region.
