String inverter SMA Sunny Island SI4.4M-13 4.4 kW single-phase
The SMA Sunny Island SI4.4M-13 is a single-phase string inverter rated 4.4 kW for grid-connected PV systems: it converts the energy of the modules into alternating current and feeds it into the building installation or the grid.
The interface protections and grid parameters are those required for connection in Italy to CEI 0-21 (low voltage) and CEI 0-16 (medium voltage).
SMA Solar Technology is the German manufacturer that set many of the standards of the PV inverter: conservative electronics, mature firmware and a service network across Europe.
