Product Description

The Goodwe GW8KN-ET Plus 8kW HV Three-Phase Hybrid Inverter combines photovoltaic generation, high-voltage battery storage, and instant backup to keep your home's critical loads operational. With 2 wide-range MPPTs, 98.2% efficiency, and IP66 protection rating, this 8 kW hybrid is ready for next-generation panels, surplus management, and silent operation, ensuring more useful kWh throughout the year.

Main Features

Nominal AC power: 8 kW (up to 8.8 kVA max. to grid).
2 independent MPPTs (1 string per tracker) with 200–850 Vdc range and maximum voltage 1000 Vdc.
Input per MPPT: I_max 16 A; I_sc admissible 21.2 A; MC4 connectors.
Compatibility with HV batteries (≈180–600 V) via CAN/RS485; charge/discharge up to ±25 A.
Three-phase EPS back-up output with UPS-type switching <10 ms for essential loads.
Max. efficiency 98.2% and MPPT performance 99.9%; night consumption <15 W.
IP66 enclosure, −35…+60 °C, wall mounting and commissioning via app/SEMS.

Advantages or Benefits

More autonomy: stores solar surplus and uses it at night or during peak tariff to reduce your bill.
Guaranteed continuity: instant backup <10 ms that protects lighting, IT, refrigerator, and automation systems.
Safe outdoor installation: IP66 and DC disconnection with built-in surge protection (SPD) as standard.
Export control: with three-phase Smart Meter limits exports and prioritizes internal consumption and manageable loads (DHW, HVAC, EVSE).
Silent and efficient: optimized electronics, no fan, and minimal conversion losses.
24/7 monitoring: SEMS portal with history, alarms, and remote diagnostics for preventive maintenance.

Purpose or Applications

Ideal for three-phase homes with medium-high consumption seeking energy independence and security against micro-outages. Works perfectly on roofs with long strings and high-current TOPCon/PERC panels (within electrical limits), and allows Time-of-Use and Peak Shaving strategies to better leverage tariffs and cut demand peaks.
