For power ranges up to 170kWp, Bonfiglioli offers the RPS450 solar inverter with an internal trans-former for feeding into the low-voltage network.
Galvanic isolation, which is compulsory in many countries, between the power supply and the generator in order to prevent the feeding of constant components is guaranteed by the internal isolating transformers.
The compact units of the RPS450 range can be interconnected as often as desired on the power supply side, which makes it possible to implement large systems and permits a flexible adjustment on the solar generator.
