Inverter – GOODWE – GW10K-ET-20_AFCI – hybrid – HV
Product details
ET G2
ET G2 is a series of GoodWe three-phase hybrid inverters with rated power of 6–15 kW, designed for homeowners. The devices help increase energy self-consumption and provide uninterruptible UPS backup power. Intelligent operating modes and load control allow system operation to be optimized to reduce energy costs.
Key benefits of ET G2
- Rated power 6–15 kW and 2–3 MPPT — depending on the model, with an MPPT operating voltage range of 120–850 V.
- UPS backup power supply — the rated apparent power of the backup circuit is 6–15 kVA, depending on the model.
- Compatibility with lithium-ion batteries — the battery voltage range is 150–720 V, and the maximum continuous charging and discharging current is 30–40 A, depending on the model.
- Smart energy management — built-in smart meter and the option to connect a GoodWe high-voltage energy storage system, a GoodWe EV charger and devices supporting SG Ready technology.
- Maximum efficiency 98.0–98.2% depending on the model and MPPT efficiency of 99.5%.
- IP66 protection rating — natural convection cooling and integrated type II surge protection devices in the DC and AC circuits.
Who is this a good choice for?
ET G2 is an option for homeowners who want to increase their use of self-generated solar energy and benefit from backup power. The series also meets the needs of households planning to integrate their system with a GoodWe high-voltage energy storage system, a GoodWe EV charger, or SG Ready devices, using intelligent load control.

The maximum input power is intermittent, up to 1.6 times the normal power. For a 1000 V system, the maximum operating voltage is 950 V. The maximum apparent power fed into the grid depends on local regulations. Both AC current rows retain the source terminology; footnote 5 specifies the maximum output current to the grid load as 13 A, 17.4 A, 21.7 A, 21.7 A and 21.7 A, respectively. Backup power of 12000 VA for 60 s requires sufficient PV and battery power. Nighttime consumption applies when there is no emergency output.
