2021 tab 320 S Boondock Victron solar settings

Retiredguy

Newbie question re solar.  We have a 2021 tab 320 s boondock.  We have two Interstate Marine, Deep Cycle, SRM 12V batteries hooked up in parallel. In our Victron app our battery setting is set at factory default: (Gel Victron Deep discharge  (2)). 

Our battery is currently at 14.49 volts and the current of the battery is at 4.3 amps. The state is now in absorption.

Float should be at 13.8 volts and absorption is now at 14.5V. according to the settings, my battery shoukd have triggered to the float mode at a absorption voltage of 14.4V.

Are my settings correct with this setup?  I worried that I might be overcharging my battery at this higher voltage.

I hope your batteries are only 12v as that is how the TaB is wired.

Yes they are 12v batteries. I didn't realize that I put down 24 volts in the original question. Lol.

The only way to get a stable idea of your voltage is to monitor the battery when it is "at rest."  What it sounds to me is that there is solar or shore power coming in, and something is running inside the trailer. 

If you can:  turn everything off.  Have a look at your Victron and check what you see.  Wait til the sun goes down (or there is little solar input) and do the same test with the battery switch off.  You will then be able to see the "actual" state of charge of your "rested" battery.

Thanks all.
