GoodWe GW12K-ET-20 – 12 kW Hybrid Inverter with 3 MPPT and Emergency Power Supply
The GoodWe GW12K-ET-20 is a powerful new-generation three-phase hybrid inverter from the ET G2 series, designed for demanding photovoltaic installations with high energy consumption and a need for reliable emergency power. With its high nominal power and support for 3 independent MPPTs, it enables maximum utilization of solar energy even under complex installation conditions.
The inverter integrates seamlessly with high-voltage energy storage systems (HV) and smart home solutions. It ensures a smooth transition to emergency power mode in case of grid failure (UPS function), which is especially important for users relying on heat pumps, air conditioning systems, or IT infrastructure. Its advanced communication options and remote monitoring capabilities make day-to-day management of the system simple and efficient.
