RV Voltages too high while charging
I have a problem and have been wrapping my head around this for a few days. I have four 100w Solar panels, and a Morningstar RJ-45 programmable charge controller wired to batteries. I have Four In...

BFL13,
I've never actually been in a situation where I "needed" to do it. I do it when I'm trying to get my controller to deliver full panel charging amps when the batteries don't need it, mostly to satisfy my curiosity and confirm that my stuff still works properly. So I apply a big DC load via running the fridge on AC through the inverter. Then the controller opens the flood gates and I can verify that the panels can deliver full rated output.
But to get around the situation you've described, I'd first disconnect the panels from the controller via a circuit breaker. Battery voltage will then drop and I can turn the finicky inverter on. Apply a load on the battery via an AC load on the inverter and then I can connect the panels to the controller again since battery voltage is being held low by the load.
