Hey everyone, dug through the forums (among elsewhere) and can’t seem to get a consistent answer (if that exists). I’m ‘upgrading’ my rv trailer to be able to run 110 loads when my generator isn’t on. I swapped out the lead acid battery for two renogy 100ah ‘smart’ lithium ones and had a renogy 2000w inverter charger in order until I read multiple threads of how this particular inverter doesn’t pass through a full 30a and loses all of its settings when batteries are disconnected. Both of those things are important and during the summer in Tx, we run the generator most of the time because A/C is a necessity. The disconnect is also a requirement as the trailer isn’t constant use, but is sitting on our hunting lease for sometimes weeks at a time and I can’t have the vampire drain of the inverter (or other things) killing the battery. It’s also a safety issue to keep things disconnected when it’s unattended. I’m looking for recommendations for an inverter charger in the 2-3kW range that has a full 30a pass through and cutover switch, and retains any settings if disconnected from 12 source. Right now I’m eyeing a victron multiplus 2000VA and a Xantrex freedom XC 2000w model…however I can’t find any documentation on them being able to retain settings after disconnection from 12v load. Alternatively, separate inverter and charger is doable, but I’d have to dig into how to wire the transfer switch so my wife or kids doesn’t turn on the genny and fry something when the main panel is connected to the inverter output. For clarity, the current plan is to take incoming shore power through a breaker and to the inverter charger, then take the output from there to the main panel where everything comes off of. No plans to run a/c or heavy loads when on battery, but want the ability to run the rest of the camper without the genny constantly on when weather is nice.
