Thinking of going solar...

It has to be on when I'm unplugged for me to continue working so that will always be on when I am on solar.

There is an elephant in the room that needs explaining. BAD.

How often do you "move"? and how many times do you end up in a place with NO shore power for more than a day or so ??

If your converter/charger is working correctly, a good set of batteries should last almost indefinitely......IF they are seldom actually used.

But I think having the inverter turned ON when not needed is a minor mistake.

And finally, you NEED a multi-meter.
You do know that the batteries need to have the electrolyte (water level) checked every couple of months......right ?? Unless they are sealed AGM type of course.

DO YOU HAVE A GENERATOR ?

I have a slight problem with threads like this because the OP gets one thing set in his mind and is like a dog with a sock and won't let go of it. You seem to be stuck on getting answers to things that you don't NEED answers to and completely ignoring other suggestions that are made.

Lacking answers and making some assumptions, it appears to me that you probably need to replace your batteries, check the converter charging voltage and then not worry about it for another 5 years or so.

So far, NOTHING you have said makes me think that you need solar AT ALL......in which case it would be an unnecessary complication and a waste of money.
