Collection: Three-Phase On-Grid Hybrid Inverters

Three-phase hybrid inverters for installations with a 400V connection: Deye SUN-5K-SG04LP3 and SG05LP3 at 5 kW, SUN-20K-SG05LP3 at 20 kW, the high-voltage SUN-125K PCS module at 125 kW, Huawei SUN2000-5K-MAP0 and Marstek Mars I Plus 12 kW with 4 MPPT.

Three-phase is what you need when the meter is three-phase: it spreads the load across the three phases and is effectively the only option above 6 kW of available power on many supplies. On models with three-phase backup, judge the power per phase and not only the total, because an unbalanced load such as a single-phase pump sits on one phase alone.

Check the supported battery voltage too, 48V or high voltage: that choice restricts which storage modules are compatible.
