question

This is yesterday (charged on shore with oem charger, always returns to 100%) and today (ran battery down last night and allowed to rest until this morning before turning solar back on and still not returning to 100% or any increase but appears fine looking at the graphs)

These are the settings specific to the battery's installed per interstate battery engineer.

This is from the Renogy controller.

Hi @bikerchic49

First things first. I think your wiring from both chargers may be incorrect, because charge isn't incrementing SOC upwards. If the negative wires from both chargers go straight to the battery rather than the load side of the shunt, then that is the problem.

Regular syncing from down as low as ~70% SOC isn't normal, and a properly tuned BMV might never need more than a 1% SOC tweak at sync, depending on how long it last saw 100.0%

I think you need to sort this first. Please ask if you need help. And oh, charge Amps are part of the sync process, so it will help if you provide that too.

This is how I currently have it hooked up

These are the settings that the main engineer from interstate battery recommended in order to get the most life and usage of these batteries

Renogy settings

Nicely labelled wires. And proof that the "Solar Ground" is connected to the wrong shunt terminal. Shift it to the one marked "Main Ground" (or it's busbar). The BMV manual is clear on this. Your SOC will then be able to register increases as it charges from the solar cc. The same applies for your shore charger.

Those batteries appear to be generic GC2 pattern floodeds. Same as I use (but different brand). These are the charge parameters I use (for 48V)..

Victron's Absorption is the same as Renogy's Boost. Don't Equalize them, and Abs shouldn't need more than about 1.5 hrs (the Victron mppt can terminate Absorb by the Tail setting, in my case 7A into 225Ah, so about 3%). They shouldn't need your 14.8V, except maybe in cold weather where Temp Compensation might push above 14.4V.

My shunt settings..

Fair bit different to yours, so you have some tuning to do I think..

So BOTH connections need switched? (Battery & solar grounds on right side and main ground on left side)

Thanks for all the help so far.

So I made the changes that you suggested and it appears to be working properly now, it was the solar wire on the wrong side. The only other thing I'm in question about is the voltage that Renogy is showing in the app. As I have four 100 watt panels mounted and wired parallel. ( I know you can test each panel individually by crawling on roof and testing with multi meter, but doesn't the Renogy app that shows the voltage coming in not a good indicator without testing with multi meter? )
