Factories and commercial sites in India are to be offered a new storage cabinet by GoodWe, a China-based maker of inverters and energy storage systems. The ESA, which delivers 125 kW and holds 261 kWh, was launched at REI Expo 2026 in Greater Noida, and up to 15 of the units can be linked in parallel for 3.91 MWh.
Rated power: 125 kW
Storage capacity: 261 kWh
Max parallel units: 15
On-grid maximum: 3.91 MWh
Target users: C&I sites
Utility container: 2 MW / 4 MWh
Container efficiency: 90.5%
GoodWe, a China-based maker of inverters and energy storage systems, launched its ESA cabinet for commercial and industrial (C&I) users at REI Expo 2026, which was held at India Expo Mart in Greater Noida, Uttar Pradesh, India. On the stand, the grey cabinet stood beneath a sign that gave its rating of 125 kW and 261 kWh. Its intended users are factories and commercial complexes, although sites without a grid connection can be served as well.
Inside the cabinet are the power conversion system (PCS), the battery cells, the energy management system (EMS) and the battery management system (BMS). Since these parts do not have to be mounted and wired separately, the company says, the unit is simpler to install, to operate and to maintain. A site is not bound to one cabinet, either. Units can be added as its demand rises, from a few hundred kilowatt-hours to several megawatt-hours, and as many as 15 of them can be connected in parallel. In on-grid use, that comes to 3.91 MWh.
Larger projects were addressed by the AC ESS, a 2 MW, 4 MWh system in a 20-foot container. GoodWe has developed its battery and PCS in-house, and it ships the container as one unit, so that it can be moved with ease and put into service quickly. The company gives its round-trip efficiency as 90.5%. It also says that the system will deliver 7% more energy over its lifetime, and that the AC and DC sections have been separated for safety and for easier maintenance.
For households, two pairs of products were on display. The ES Uniq hybrid inverter was shown with the Lynx A G3 battery, while the ET LV hybrid inverter was shown with the Lynx A G4.
As GoodWe celebrates 10 years in India, we remain committed to driving the country’s clean energy transition through innovative and reliable solutions. The launch of our ESA 125kW/261kWh BESS at REI 2026 reflects our continued focus on delivering advanced energy storage solutions across residential, C&I and utility-scale segments.Aniket Sawant, Country Head, GoodWe India
The 125 kW, 261 kWh rating was seen on more than one stand at the show. Gautam Solar presented a liquid-cooled 125 kW, 261 kWh cabinet with IP55 protection for outdoor sites, and SolaX Power showed its ESS-TRENE cabinet of the same rating, which stores its energy in LFP cells of 314 Ah.
