18-25kW | Three Phase | 2 MPPT
This new series of three-phase output inverter has wider range of 18kw, 20kw, 25kw than the original series, at the same time still got two integrated MPPTs, allowing two-array to input from different roof orientations. In addition, it allows the system to be monitored and controlled remotely.
