Fimer India’s PowerUNO and PowerTRIO series hybrid inverters are rated for maximum 1-phase and 3-phase power output of 6 kW and 10 kW, respectively
These inverters can be paired with the PowerX series battery bank, whose energy storage capacity can be scaled up to 30 kWh
The commercial availability of these products is Q2 2026
During the Renewable Energy India (REI) Expo 2025, the TaiyangNews team spoke with C-level representatives from various participating companies to gain insight into their latest products, future strategy, and market outlook, among other topics. Xavier Scaria, Chief Technology Officer (CTO) of Fimer India Pvt Ltd., the Indian arm of Italy-based manufacturer of PV inverters, energy storage systems, and electric vehicle (EV) chargers Fimer S.p.A, elaborated on the company’s latest residential products and market strategy.
The company introduced its PowerUNO and PowerTRIO series hybrid inverter, targeting India’s 1-phase and 3-phase residential solar-plus-storage prosumers, respectively, at the event. For excess solar energy storage or providing backup during an emergency, prosumers might connect these inverters with the PowerX series vertically stacked lithium-iron-phosphate (LFP) battery bank. While the 1-phase variant offers a range of power output (AC) of 2.0 kW to 6.0 kW, the 3-phase inverter is rated for a range of power output (AC) of 4.0 kW to 10 kW. Equipped with 2 MPPT channels with a rating of up to 16 A (DC) and a battery power connector (±), both inverters can be coupled with a PV array and a battery bank in either AC or DC-coupled configuration. The AC-coupled design is suited for new installations, while the DC-coupled alternative supports revamping existing plants. Scaria states that all the above-mentioned inverters, when paired with the PowerX battery bank featuring 5 kWh of battery packs, can scale storage capacity to 30 kWh by connecting 2 battery units of 15 kWh (3 × 5 kWh) in parallel. This flexibility in storage helps prosumers enhance self-consumption by storing excess solar energy (after captive consumption) and discharging the same in peak demand hours, typically of high electricity tariff rates. It also provides backup during grid failure or shutdown. Given the complexity of managing the entire connected load from multiple energy sources, like solar, storage, and grid, in real time, Scaria pitches for the Aurora Vision portal. This cloud-based web portal monitors and controls energy flow and key performance metrics of the solar-plus-storage system through Wi-Fi. These products are scheduled to be commercially available in India from Q2 2026.
Apart from the showcased products, Scaria briefly mentioned the commercially available central inverters with a power output range of 1.1 MW to 4.4 MW and battery energy storage systems.
Moving to the manufacturing capabilities, he shared that the company has 2 manufacturing plants, one each in India and Italy. While these showcased solar-plus-storage products will be shipped initially from the Italian factory, they are scheduled to be locally manufactured at the Indian factory from June 2026. In addition, the company has already begun local fabrication of string inverters up to 100 kW. The company has launched its research & development (R&D) operation, led by Scaria, which will design and develop all its central inverter products, either on-grid or battery-tied, to address growth in India’s solar-plus-storage market.
He cites an example of a standalone BESS project in Leh, Ladakh, where Fimer’s systems are installed and operating without any efficiency derating. Furthermore, the company has supplied up to 33 GW of power conversion products (PV inverters and BESS) for a wide range of Indian customers, such as NTPC, Avaada, and Amp Energy, among others, until now.
