Mr. Idrish Khan, C.T.O – India, Solis

“Solis has a strong legacy of delivering proven solutions to the global PV industry for more than 20 years and has completed more than 10 years of operations in India. As the Indian market evolves from conventional on-grid solar towards energy storage and flexible energy management, Solis is well positioned to address both the current and future requirements of the market through its energy storage portfolio.”

India’s energy-storage market is rapidly moving beyond standalone solar towards flexible and dispatchable energy systems. What major opportunities does Solis see across C&I, residential and utility-scale BESS applications, and how is the company positioning its energy-storage portfolio to address these evolving requirements?

• Rapid growth of standalone BESS: Storage is increasingly being deployed as an independent grid asset for peak shifting, energy arbitrage, ancillary services and grid balancing. India had reached 9.3 GWh of cumulative installed battery storage capacity by June 2026, with standalone BESS accounting for 83% of cumulative capacity.
• Solar + storage and RTC applications: Storage is increasingly being combined with renewable generation to improve dispatchability and support round-the-clock renewable power. The government has also highlighted storage as essential for integrating increasing solar and wind capacity.
• Strong government support: VGF schemes, Energy Storage Obligations, procurement frameworks and transmission-charge incentives are helping improve project economics. Current government-supported BESS programmes cover tens of GWh of planned capacity.
• Increasing focus on grid services: BESS is being positioned not only for energy shifting but also for frequency regulation, voltage control, congestion management and other grid-support functions like FRT, LVRT, HVRT frequency support and support to grid in instability cases.
• Growing C&I requirement: Commercial and industrial customers are likely to increasingly use storage for peak-demand management, time-of-day optimisation, backup power and renewable-energy integration. This creates opportunities beyond utility-scale tenders.
• Localization and supply-chain development: India is simultaneously developing domestic battery and energy-storage manufacturing capabilities, which should support the growth of the wider ESS ecosystem.

Solis has a strong legacy of delivering proven solutions to the global PV industry for more than 20 years and has completed more than 10 years of operations in India. As the Indian market evolves from conventional on-grid solar towards energy storage and flexible energy management, Solis is well positioned to address both the current and future requirements of the market through its energy storage portfolio.

The key opportunity we see is the transition from standalone solar generation towards flexible, dispatchable and intelligent energy systems. Increasing demand for Time-of-Day (TOD) optimization, peak shaving, backup power, renewable-energy self-consumption and improved power reliability is creating new opportunities across utility, commercial & industrial (C&I), and residential segments.

For the C&I and residential segments, Solis hybrid inverter solutions provide an integrated platform combining PV MPPT, battery charging, PCS functionality and energy-management capabilities. This allows customers and EPCs greater flexibility to design systems according to their application requirements, including solar self-consumption, TOD optimisation, peak shaving, backup and off-grid operation. In the residential segment, hybrid systems are particularly relevant in locations where grid reliability is a concern and uninterrupted power availability is important.

A significant opportunity is also the increasing adoption of solar-plus-storage solutions in the C&I segment. Commercial and industrial customers can use battery storage to reduce peak demand, optimise energy consumption based on tariff periods, increase utilisation of rooftop/onsite solar generation and provide backup during grid interruptions. This moves the value proposition beyond simply supplying a solar inverter and towards providing an integrated energy-management solution.

Another important opportunity is utility-scale and large-scale BESS, where the requirement is moving towards dedicated high-power PCS, EMS integration, grid support and renewable-plus-storage applications. This represents a separate but complementary growth opportunity for Solis as the Indian BESS market develops and customers increasingly look for integrated and reliable power-conversion solutions.

Solis also sees an opportunity in providing a complete energy-storage ecosystem, including hybrid/PCS solutions, batteries and associated energy-management functionality. Offering compatible components under one solution portfolio can simplify system design, improve system integration and provide customers and EPCs with a single technical interface for commissioning and support, compared with coordinating multiple independent equipment suppliers.

Therefore, we see the major growth opportunities for Solis in India across three key areas:

• C&I Energy Storage: Peak shaving, TOD optimisation, solar self-consumption, backup power and energy management.
• Residential Hybrid Storage: Solar-plus-storage and backup applications, particularly in areas with unreliable grid supply.
• Utility-Scale BESS and Solar + Storage: High-power PCS, renewable integration, dispatchable renewable energy and grid-support applications.

Overall, the opportunity is not simply a shift from on-grid inverters to batteries. It is a broader transition from solar generation to intelligent, flexible and storage-enabled energy systems. Solis can leverage its established PV experience, local market presence and expanding energy-storage portfolio to participate across these applications and support customers as their energy requirements evolve.

What key innovations set EverCore ESS apart in Solis’ storage portfolio?

For Indian C&I customers, Evercore features are particularly relevant because storage is increasingly being considered not only for backup, but also for peak-demand management, tariff optimization, renewable-energy integration, and improving power reliability. An integrated solution can also simplify system design, installation, commissioning, and overall energy management. In short: EverCore moves beyond conventional battery backup by combining energy storage, power conversion, solar integration, and intelligent energy management into one platform, making it suitable for the evolving requirements of Indian C&I energy users.

EverCore ESS is designed as an integrated energy-storage solution that combines battery storage with power conversion, energy management, and backup functionality in a single system. Its key innovations include:

• Integrated PCS + MPPT + STS + EMS: EverCore combines the key power and energy-management functions into one solution, reducing system complexity and simplifying deployment.

What are the key features of Solis EverCore ESS, and how does its integrated PCS, MPPT, STS and EMS architecture help Indian C&I customers address peak demand, tariff optimisation, solar integration and backup requirements?

• Its key advantage is the modular and stackable design, which allows customers to configure the storage capacity according to their actual energy requirements and scale the system as their demand increases. This provides a more flexible approach compared with adopting a large centralized ESS from the beginning.
• FlexCore-ID is particularly well suited for small and medium-sized C&I applications, large residences, hospitals, shopping malls, small farms, and other distributed-energy applications where scalability, flexibility, and reliable energy management are important.
• The system uses LFP battery technology, with each battery pack providing approximately 20 kWh, and offers a long operating life with a specified cycle life of at least 8,000 cycles under the applicable operating conditions.
• From a strategic perspective, FlexCore-ID supports Solis’ modular energy-storage approach by enabling customers to start with the capacity they need today and expand the system as their energy requirements grow, without immediately moving to a large centralized ESS architecture.
• Overall, FlexCore-ID enables customers to right-size their battery capacity more precisely and expand the system progressively, providing a flexible alternative to moving directly to a large centralized ESS architecture.

How is Solis IntelliHome redefining residential energy storage by combining LiFePO₄ batteries, intelligent energy management and hybrid inverters, and how can it help Indian homeowners optimise solar self-consumption, electricity costs and energy resilience?

• The future of residential storage is not simply about storing electricity, but about intelligently deciding when energy should be generated, stored, consumed, or exported. IntelliHome is designed around this approach, making residential energy storage more intelligent, flexible, and user-oriented.
• IntelliHome combines LiFePO₄ battery technology, intelligent battery management, and seamless communication with Solis hybrid inverters to create an integrated residential energy solution. Its flexible architecture allows homeowners to expand their storage capacity according to their evolving energy requirements, while simplified commissioning helps make installation more straightforward.
• The key differentiator is the intelligent energy-management layer. By considering factors such as electricity tariffs, weather forecasts, solar generation, and household consumption patterns, the system can intelligently determine when energy should be stored, used, or exported. This allows the battery to operate as an active part of the home’s energy ecosystem rather than simply functioning as backup storage.
• For homeowners, this means greater solar self-consumption, reduced dependence on grid electricity, improved energy resilience, and the potential to optimize electricity costs, while maintaining a simple and user-friendly experience.
• In this way, IntelliHome represents the shift from “storing energy” to “intelligently managing energy”—helping homeowners make better use of every unit of energy their home generates. `

With India’s utility-scale solar capacity continuing to grow, how is Solis’ utility-scale inverter technology helping developers optimise DC/AC ratios, accommodate high-current PV modules and maximise energy yield, plant availability and long-term project economics?

India represents one of the world’s most important solar markets, with strong solar resources, rapid renewable-energy deployment and increasing integration of solar generation into the power system. India’s National Electricity Plan projects solar capacity of around 185.6 GW by 2026–27, with renewable energy expected to contribute around 35% of total electricity generation in that year.

This creates a market where inverter technology needs to address not only higher installed capacity, but also grid integration, high solar penetration, modern high-current PV modules and project-level economics.

• One of the key advantages of Solis’ utility-scale inverter platform is the flexibility to optimize the DC/AC ratio according to the site’s solar resource and project economics.
• For example, with a 300 kW AC inverter, a 1.5 DC/AC ratio allows up to 450 kWp of DC capacity to be connected. Assuming an illustrative specific yield of 1,600 kWh/kWp/year, the 450 kWp PV array has a theoretical annual generation potential of approximately 720 MWh, before accounting for inverter clipping and other system losses.
• The advantage of 150% DC oversizing is that the larger PV array can help the inverter operate closer to its available AC capacity for more hours of the day, particularly during morning, evening and lower-irradiance conditions. This can improve the utilization of the available 300 kW AC capacity and support higher annual energy delivery.
• Over a 25-year project life, the theoretical energy potential would be approximately 18 GWh before considering degradation and other losses. The actual lifetime energy delivered to the grid will depend on site irradiation, clipping, temperature, system losses, availability and module degradation.
• This demonstrates Solis’ approach of optimizing the overall plant energy yield and lifetime project value, rather than focusing only on inverter AC capacity. By combining high DC oversizing capability with high-current module compatibility, intelligent monitoring, thermal management and grid-support functions, Solis aims to help developers maximize energy generation, plant availability and long-term project economics.
