Hi,
I have an motorhome (i call it the "bus") with 3.27kw of solar on it and an additional 1.962kw when the ground panels are deployed for a total of 5.232kw. When we travel it works great. The problem is all the solar just sit there with my batts fully charged doing nothing when I'm home. I'd like to power the house off the bus. So, what's the easiest way to do this? I assume the 120v bus inverter that's not designed to be attached to a grid wont work. If i get a grid tied inverter can i back feed a double pull breaker and just have a transfer switch on the bus to feed the inverter. I already have charge controllers on the bus. Are their any cheaper options that don't have the mppt built in and can just be fed 46-56 volts dc from the bus charge controllers? I would use most of the power during the day so there wouldnt be much back feeding to the grid. I understand if i don't have a bi directional meter and net metering set up i wont get credit for any extra, but will they have any problem or bill me more because i might back feed a little? I'd rather not do the whole permit thing which i think would be required to get net metering.
Thanks,
Cody
