Thank you, all makes sense. As I sit right now, the dealer only gave me one battery thus waiting on the BB's to get here. Does turning the solar charge controller off cut power to the batteries from the solar? I guess what I am asking is if in theory the solar is making some power all the time, where is it going if the charge controller is off? When I have to switch out and hook up the BB's I'm just looking for the proper way to de-energize the system to allow a person to work on it.

Whenwver you do work on the solar circuit you should disconnect the solar feed to the controller and then the battery feed. Reconnecting, battery first then solar. It's required for the controller to correctly calibrate and power cycle.
Tape over the bare wires if you have a screw terminal connection and/or don't have nylon connectors on the solar panel to controller wiring run, as they'll still be putting out 12-48V depending on your configuration. Nylon disconnects are a cheap investment. A disconnect switch is a bit more expensive and overkill in my experience since it's rare to need a full disconnect.

There's no particular "docking procedure," per se. We leave the solar controller and inverter on all the time. That way, if shore power goes out while connected (which it did several times yesterday at the Army FamCamp where we are currently staying), the batteries, solar, and inverter keep the fridge running. The ATS (automatic transfer switch) handles everything for you.

Thanks for the update. I found someone who will install the panels and controller and inverter for me, but I might have to wait until October to have it done. But I appreciate the update.

I have a separate question but may be useful to those already asking about solar.
I have TWO jaboni 390W panels, Jaboni 30amp controller and 4 Lion Energy u-1300 (110 amp hour) ion batteries.
1 panel, controller and wiring were done factory
other panel and 4 li-on batteries installed by dealer.
I have a dual source (elec and propane) 18 cu fridge.
Assuming sunny days, and generator running so AC can be turned on.
What is a reasonable expectation of battery life overnight with no generator running?
problem - I had disconnected my propane to go fill both tanks. Fridge running on AC only, two laptops plugged in. water pump but nobody home. This was at 2:00 sunny day. Came back by 10:30 pm and batteries were almost completely dead, luckily go generator running to charge the batteries. Seems like a problem...

So, only one solar charge controller? If so, based upon other threads regarding expanding the factory solar panels, that charge controller can only handle a max of 540 watts (per documentation) or real world, more like 500 watts. Perhaps you're not getting full battery charging from the solar. Unclear how you were running on AC for the fridge unless the AC leg is wired to the inverter. Do you have a battery monitor? Are you able to track your solar charge status using the solar app?

The frig running on AC will suck down the batteries. We always switch to propane when not connected to shore power. The solar usually keeps the batteries charged if not parked under trees! I usually see about a .2 volt drop from dusk to dawn without running the furnace at night, (that will draw down the batts at night if run constantly).
