Battery SOC Low - Voltage Normal
Hi All. I'm new here so go easy on me. I've Googled for hours but can't find any solid answers. My setup is in my signature. So here's my issue.... Whether plugged into shore power, running my ...

I think the EP controller can only guess at state of charge if you use the dedicated 'load' outputs, (most wouldn't on an RV because you already have a distribution system for 12v). The remote tells you the voltage at the charger output, which is virtually paralleled to the DC converter output as well as the battery, with fairly large wiring. Plus, as somebody pointed out, if you add energy with other charging, the EP can't know that you did. Only the type that has a shunt bolted at the battery can monitor everything coming and going, and those are a great tool to learn how much everything uses.
Meanwhile, I think you can get 14.8 equalizing charge out of your solar controller, just turn off the dc converter, and don't use the lights or any dc loads while you'r doing it, since the voltage is a little high. Start when you've got good sun, of course. I would do one at a time, since the equalization really overcooks the good cells in the hope of adding current to the cell that's sitting low, and your set up will be a kind of low amperage with 3 batteries, I think, for that operation.
