P-GR series · 4 – 6 kW
Grid-tied hybrid inverter with export, SPD surge protection and AC-coupling, offering excellent value for money.
Price on request
The P-GR series brings the features of a full hybrid inverter at an accessible price: it exports surplus to the grid, can be AC-coupled with an existing string inverter or microinverters, and accepts a generator. The wide MPPT range starting at 90 V also suits short panel strings.
Grid-connected homes, prosumers and existing systems getting added storage.
