GoodWe GW8000-ET-20 Hybrid Inverter 8 kW Three-Phase
The GoodWe GW8000-ET-20 is the 8 kW three-phase hybrid inverter of the ET G2 series, designed for residential and small-business PV systems with high-voltage storage (battery range 150-720 V, 500 V nominal). It manages 2 independent MPPTs with 16 A per tracker, a maximum PV voltage of 1,000 V and an MPPT range of 120-850 V, and accepts up to 12,800 W of installed PV power.
For storage it reaches 30 A continuous charging and discharging, with 12,000 W charging power and 8,800 W discharging. The three-phase back-up function delivers 8,000 VA (up to 16,000 VA peak) and starts automatically in the event of a grid outage. Maximum efficiency is 98.0% (97.2% European), protection is IP66 with natural convection cooling (no fans) and communications include Wi-Fi, LAN, Bluetooth, RS485 and CAN as standard. Type II surge arresters are integrated on both the DC and AC sides; AFCI for arc fault detection is available on the dedicated versions.
Key features
High-voltage battery150-720 V range with 30 A continuous charging and discharging: fast recharging and lower cable losses.
2 independent MPPTs2 trackers of 16 A each, with PV voltage up to 1,000 V, to manage roof sections with different orientations.
Three-phase backupWhen the grid is down the emergency output delivers 8,000 VA (up to 16,000 VA peak).
Integrated protectionsType II DC and AC surge arresters, insulation and residual current monitoring, anti-islanding and remote shutdown.
Full connectivityWi-Fi, LAN, Bluetooth, RS485 and CAN as standard for the SEMS portal, meter and battery BMS.
Outdoor installationIP66 and natural convection cooling without fans, with an operating temperature from -35 to +60 °C.
