Inverters GoodWe GW15K-ET
GoodWe ET Series Inverter
The GoodWe ET Series inverter, ranging from 15 to 29.9, is suitable for large residential PV projects and small commercial projects. The GoodWe hybrid inverter features an integrated switching device for backup power supply. In case of a grid outage, the inverter can continue to power the home with 3-phase emergency power. The hybrid inverter is capable of black-start and can charge solar energy.
The trend towards increasing power of PV modules has an impact on the overall requirements for photovoltaic installations. As leaders in development, we are working to ensure that GoodWe ET Series inverters meet the needs of high-power rooftop solar installations by facilitating backup power supply, reducing peak loads through peak-shaving, and managing loads to increase self-consumption and lower electricity costs. The ET Series can be combined with energy storage systems of various capacities and brands, including GoodWe Lynx Home F.
