GoodWe GW29.999K-ETA-G20 Hybrid Inverter 30 kW Three-Phase

The GoodWe GW29.999K-ETA-G20 is the 30 kW three-phase hybrid inverter module of the ESA storage system (high-voltage All-in-One): a single stackable solution in which the inverter and the lithium iron phosphate (LFP) batteries are integrated in the same cabinet. It has 4 independent MPPTs, a maximum PV voltage of 1,000 V with an extended MPPT range of 120-950 V, and accepts up to 60,000 W of installed photovoltaic power.

The battery works at high voltage (750 V nominal, range 700-950 V) with charging power up to 30.0 kW and discharging power up to 33.0 kW. The three-phase back-up output delivers 33.0 kVA (45.0 kVA for 10 s) and comes into operation with a switchover time of less than 4 ms. Maximum efficiency reaches 98.2% (97.4% European), the protection rating is IP66 with smart fan cooling, and connectivity includes Wi-Fi, LAN, Bluetooth, RS485 and CAN for the BMS as standard. Type II DC surge arresters (Type I+II optional) and Type II AC surge arresters are built in; AFCI and rapid shutdown are available as an option.
