Product overview
The second generation of the ET series.
The GW10K-ET-20 connects two or three MPPT inputs, a 150–720 V lithium-ion battery and the three-phase grid. GoodWe adds 12 and 15 kW classes in this generation, allows PV input up to 160 % of nominal power and supports up to four units in parallel. The backup output switches in under 10 ms, and an integrated dry contact can switch external loads.
- Two or three MPPT inputsTwo MPPT inputs on the 6 and 8 kW models, three from 10 kW; 16 A per MPPT, 120–850 V.
- High-voltage batteryLithium-ion batteries from 150 to 720 V with up to 40 A continuous charge and discharge current.
- Backup in under 10 msUPS-level switching to the backup output in under 10 ms.
- IP66, Type II SPDIP66 enclosure with Type II surge protection on the DC and AC sides; AFCI 3.0 is optional.
