I'm guessing most all of these coaches use the same method for measuring state of charge (soc) They are junk. Not accurate at all. You have to measure everything coming and going from your batteries through a shunt or you will never know. Selecting on your panel to use the inverter as the shunt doesn't work the same way and is not accurate. I added a Victron VMB-712 battery monitor (google it and search on youtube to see how it works and how easy it is to install) to my system and it is as accurate as you will find and you won't see the changeling % you are wondering about and be able to take much better care of batteries by not running them down to far. I have no affiliation with Victron, I just like their products. Even if you don't use solar, this is a must have in an RV in my opinion, otherwise you never know the SOC of your batteries.
