SMA Sunny Boy SB700U Solar PV Grid Tie Inverter 700 watt LCD 120VAC WORKING 700U. This is the only 120ACV UL certified grid tie inverter that is made to my knowledge. How this works is you wire the AC side into a single pole circuit breaker and the DC side would be feed from your solar panels. What you dont use in your house will go to the grid (Power company) will install a net-meter that runs both ways. Im sure that all power companies require at least the UL1741 certification. There are no batteries you use or send back 100% what solar energy you harness. The inverter works great. I have now upgraded to a 3200watt inverter.
