Wanting to add extended boondocking capability to the travel trailer.
I can add capacity to oem 12v system (which has a lifepo4 charger) with a 400ah battery right next to the panel, less than 2 foot cable run.
Should I have two "independent" systems by adding an EG4 3000EHV-48 (with a 48v 100ah battery and 1500 watts solar) and wire the inverter output to the distribution panel and the shore power to the inverter a/c input? Or just have two 48v batteries and letting the oem 12v system run off of the inverter and living with the inverters idle consumption but having increased capacity for running ac fridge and air conditioner?
Writing this out makes me think putting in a smaller 100ah 12v and 2 48v batteries would be a better solution.
So the 12v battery would really only be useful if the 48v batteries were depleted and there was no/insufficient solar, like night time, so we'd still have lights and water.
Where am I going wrong?
Thanks for any advice/insight
