Solis S6-EA3P6KAA-NV-ND-H 6kW Three-Phase AC Coupled Inverter for HV Batteries
The Solis S6-EA3P6KAA-NV-ND-H, 6kW across three phases, belongs to the S6-EA3P range of AC coupled storage inverters: they have no solar inputs and connect on the AC side of the installation. Their only task is charging and discharging a high voltage battery, which makes them the obvious choice when storage has to join a PV system that is already producing, leaving the string inverter where it is.
Compared with the 5kW model this size gives a little more headroom for homes with heavy evening loads or a heat pump. The battery stays on the high voltage side, with declared compatibility across several lithium brands, and charge and discharge current for the range reaches 25A.
The range schedules charging and discharging over six programmable time-of-use windows and offers peak shaving to keep grid draw in check; two RS485 ports link battery and monitoring system and enable remote updates and VPP control. Installation and commissioning are a job for qualified personnel, following the local connection rules.
