Solis Marks 20th Anniversary at REI 2025, Launches 125kW C&I Energy Storage Inverter

Solis, a leading solar inverter manufacturer, is participating in a big way at the Renewable Energy India (REI) Expo 2025, from 30 October to 1 November 2025 at India Expo Mart, Greater Noida. This year marks a significant milestone for Solis as it celebrated its 20th anniversary, with visitors invited to explore its innovations at the expo. The Solis stall is located at Booth No. 620, Hall No. 14,  strategically located as the first booth near the registration area.

Solis unveiled its latest innovation—the 125kW C&I Energy Storage Inverter (S6-EH3P(75-125)K10-NV-YD-H) at the show. The inverter has received a strong response from visitors, with strong interest from the targeted segment. The solution is designed to meet the growing demand for efficient commercial and industrial energy storage, delivering reliability, scalability, and smarter energy management.

The S6-EH3P(75-125)K is Solis’ 4-in-1 hybrid inverter, integrating PV generation, battery smart charging/discharging (PCS), on/off-grid switching, and genset switching (STS), and smart energy management system (EMS) into one intelligent solution. With an IP66 outdoor protection rating, it can continuously operate in harsh environments like sandstorms and heavy rain.

In addition, the unified algorithms and control sequencing reduce inter-device coordination delays and prevent interlocking failures. This results in faster delivery, more agile responses, and a more stable system. The EMS manages the coordination of the battery, PV, load/grid/genset, supports policy deployment, remote operation, and fault self-healing—leaving complexity in the factory while bringing reliability to the field.

Key Features of the S6-EH3P(75-125)K Hybrid Inverter:

 1.  Super Strong Photovoltaic Integration, Accelerating Investment Returns

•  2x Ultra-high Photovoltaic Capacity Ratio: The system supports photovoltaic power generation up to twice the rated capacity, with 10 MPPTs to significantly improve generation efficiency. It supports 21A high-current modules, compatible with future technologies. More power generation during the day and faster charging times, especially for energy-intensive facilities such as hotels and hospitals. This enables the "full charge during the day, sufficient use at night" model, significantly shortening the investment payback period.

2. Top Off-grid Performance, Ensuring Zero Interruption for Critical Operations

• 2x Off-grid Overload Capacity: Industry-leading instantaneous overload capability, easily starting high-power inductive loads such as air conditioners and elevators.

• <10ms Seamless Switching: Fast grid-off/grid-on switching within milliseconds, twice as fast as traditional systems. This ensures sensitive equipment and continuous production processes remain uninterrupted during grid instability, providing power protection similar to an "online UPS" system. This ensures uninterrupted operations for factories, malls, and critical data during grid failures.

3. High Protection Rating, Suitable for Outdoor Applications

• High Protection Rating IP66: Supports direct outdoor installation, ideal for outdoor environments. The higher protection rating ensures better equipment protection and reliability. This eliminates the need for indoor storage space for the energy storage system, making site selection more flexible and enhancing lifecycle reliability while reducing the risk of failures.

• In addition to this product launch, Solis will also display its latest portfolio of advanced solar inverters, including:

Solis Utility Inverter: S6-GU3P350K06-EV-ND – Engineered for large-scale utility applications.

• Larger Single-Channel MPPT Current – Solis inverters support a maximum single-channel MPPT current of 80A, enabling the use of higher-power solar modules and minimizing DC-side power limitations, thereby enhancing system flexibility and efficiency.

• Superior High-Temperature Output Capability – Solis inverters maintain their rated DC voltage output even at 35°C without derating. This ensures stable performance in high-temperature environments, effectively reducing the impact of temperature on efficiency and ensuring reliable operation in more demanding conditions.

Solis C&I Grid-Tied Inverter: S6-GC3P(150-200)K07-ND for C&I installations 

• AFCI with RSD: Solis integrates AFCI functionality with Rapid Shutdown (RSD), ensuring immediate disconnection when an AFCI fault is detected. This provides enhanced safety for commercial and industrial PV systems, meeting UL 1699B and IEC 63027 standards for arc protection and quick shutdown.

• Electronic DC Switch: Equipped with advanced electronic switches, the inverter automatically disconnects power in case of DC reverse polarity or short-circuit faults, offering superior durability and protection compared to mechanical switches.

• DC and AC Terminal High-Temperature Detection: The inverter continuously monitors terminal temperatures and automatically shuts down with an alarm if temperatures exceed safe levels, minimizing risks associated with abnormal connections.

The Solis India team, alongside its global technical experts, waspresent to guide visitors through the technology and highlight how Solis’ innovative solutions are enabling a sustainable energy future.

“REI 2025 is not just an exhibition for us; it is a celebration of two decades of dedication to renewable energy innovation,” said Honey Raza, Indian Country Manager of Solis, while inviting visitors to check out the wide portfolio offerings from Solis.
