This project consists of both micro-inverters and a string inverter. Pictured is the South facing PV array which is connected to one SMA TLUS 4000 watt inverter. The modules are Solar World 275 Mono, made in USA. The East facing roof consists of the same modules, which are connected to their own Enphase micro-inverter. Installed this summer, the homeowners have already amassed a surplus of credits on their newly installed bidirectional utility meter!
