SMA SB-3.8-US Sunny Boy 3800 Watt Grid-tie Inverter
SMA's latest generation of grid-tie inverters features the well established Secure Power Supply (SPS), integrated disconnect, mutiple MPPT tracking inputs, and enhanced AFCI technology. The SPS allows up to 3800 watts of loads to be powered during utility outages, while the sun is shining on the panels, with no battery bank required. Multiple MPPT inputs allow for a variety of string lengths and panel combinations. The enhanced AFCI technology reduces false tripping while improving sensitivity to real arcs.
The SB series are string inverters that utilize arrays of solar panels wired for high voltage DC power delivery.
