GoodWe ESA GW9.0-BATD-G20 (High-Voltage Battery) 0.5C/8.7kWh

The GoodWe GW9.0-BAT-D-G20 is a 9.0 kWh LFP (LiFePO4) battery module for the ESA Series all-in-one ESS, providing 8.7 kWh of usable energy per module — the highest capacity in the range and the module needed to reach the full 108 kWh system with twelve units. Based on Lynx D G2 technology, it delivers 4.5 kW maximum continuous charge and discharge power with a peak of 6.75 kW for 10 s, drawing up to 10.7 A and delivering up to 11.8 A, and operates across 700–950 V in a three-phase system (350–550 V single-phase). Integrated heating extends the range to a charging temperature of −20 °C to +55 °C and a discharging temperature of −20 °C to +55 °C, and integrated aerosol fire extinguishing is built in — keeping the module available and protected through Baltic winters without an extra enclosure. Up to 12 modules stack in one system (max. 6 in a single column), mixing capacities or combining new and existing modules. Rated IP66 for 4–100% RH and altitudes to 4000 m, it runs at ≤27 dB and communicates over CAN & RS485. Dimensions 800 × 326 × 270 mm at 77 kg, floor-stacked, wall-mounted or grounded. Cycle life ≥10 000. Certified to IEC62619, IEC60730, EN62477, IEC63056, IEC62040, CE, CEC, Regulation 2023/1542 and VDE-AR-E 2510-50, with CE/RCM for EMC and UN38.3/ADR for transport.
