SOLO 500
This high-quality photovoltaic SOLO 500 inverter is intended for feeding photovoltaic energy into the public grid with a very high efficiency. Through the liquid cooling of the inverter heat is taken out efficiently from the operating room.
The SOLO 500 photovoltaic inverter series with liquid cooling is used in grid connected photovoltaic applications.
