GoodWe GW5.1-BATD-G20 (HV-Battery / Stackable)

The GoodWe GW5.1-BAT-D-G20 is the 5.12 kWh LFP (LiFePO4) battery module for the ESA Series all-in-one ESS, providing 5.0 kWh of usable energy per module. It handles 5.0 kW maximum continuous charge and discharge power with a peak of 7.5 kW for 10 seconds, drawing up to 12.0 A and delivering up to 13.2 A, and operates across 700–950 V in a three-phase system (350–550 V single-phase). Integrated heating extends the usable range to a charging temperature of −18 °C to +55 °C and a discharging temperature of −20 °C to +55 °C, so the module stays available through Baltic winters without an insulated enclosure. Up to 12 modules can be stacked in one system, mixing capacities or combining new and existing modules. The module is rated IP66 for 5–95% RH and altitudes to 4000 m, runs at ≤29 dB, and communicates over CAN. Dimensions are 800 × 326 × 270 mm at 57.5 kg, floor-stacked or wall-mounted. Certified to IEC62619, IEC60730, EN62477, IEC63056, IEC62040, CE and CEC, with CE and RCM for EMC and UN38.3 and ADR for transport.
