Battery charging with generator
I have a grid tie-in with battery backup system. It is an Outback system with 3.2kw solar panels. This winter in northwest Illinois we had 12 days with little if any sun. I would like to be able to use a generator to recharge my 48v battery bank during these long periods of no sun if the grid goes down. I have an input for my generator to my subpanel but this would require running the generator all the time. If I could connect it direcly to the DC side of my system I would only need to run it for a short period of time to just give me enough battery power to carry me to the next sunny day. Any suggestions?
