Is there any way to temporarily disable the Multiplus fromcharging. For days at a time I don’t want it charging my Lithium batteries. Instead of a charge only mode, I’m looking for an Inverter mode only instead of a Charger mode only. A second option is to find a manual switch to use on the 120volt line feeding the inverter and feeding the RV, so when I am at shore power I could set the switch to bypass the inverter and feed the AC fuse panel directly, with a secondary switch to possibly feed the inverter for charge if needed. I have seen someone manually build these, but do not feel confident enough to. Wire this myself.
