GoodWe GW12K-ET-20 G2 AFCI

GoodWe GW12K-ET-20 – 12 kW Hybrid Inverter, 3-phase (G2, AFCI)

The GoodWe GW12K-ET-20 inverter is a modern device from the ET G2 series, delivering high performance, smart operating modes and reliable backup power. It provides AC power of 12 kW, supports HV batteries 150–720 V, and offers charge/discharge current up to 40 A. Thanks to 3 independent MPPT (input current 16 A, MPPT range 120–850 V) it enables flexible PV design and maximized energy yield. The backup section supplies 12 kVA (up to 18 kVA for 60 s), allowing key loads to be powered even during grid outages. Advanced protections — including optional AFCI 3.0, DC SPD Type II and AC SPD Type II — together with protection class IP66 ensure safe operation. The inverter operates quietly (<45 dB) and comes with a 5-year warranty, extendable to 10/15/20 years.
