Hello, I just wanted to ask if this setup sounds correct for a backup with a generator. I have a travel trailer with a 1600W air conditioner (3900W Startup). I want to have a 2800W generator to back up in case of loss of shore power. I am looking at the Multiplus 3000W 12V to 120V, and a 60A MPPT to handle the 800W of solar into 2400W of lifepo4 battery. The generator has an autostart feature that works when it senses a closed loop. So, my idea was to have the inverter installed normally with AC coming in from a Automatic Transfer Switch. I would have a rely that would close when shore power is lost thereby closing the loop and starting the generator. The ATS would switch to generator power and send it to the multiplus. Does this sound workable?
My questions are about the battery charging. Since I will be charging from solar and the multiplus, is there a way for the units to communicate so as to not send too much current from both units together? Any other devices I should have besides the multiplus, solar controller, and ATS?
Thanks!
