THE Grid Tie Power Inverter 600Watt Solar Panel 10.5V to 28V Generator UK Plug
This unit was way better than I expected.  I hooked up the solar panels, wired the unit up and it worked right off.  It takes a short time for the unit to sync up but it has been operating for the past week with no problems.  I checked my electric meter to see if it actually works, was pleased to see that the capacity I hoped for was right on.  I also tested to see that the unit shut down properly when there is a power failure.  I would recommend this device to those whom are interested in solar.
