Great Day!

Well, maybe not completely. My PJ has a lcd meter for ac power readings and battery readings. Battery’s readings lcd is from the built in solar charge controller that I didn’t use because it’s limited to 36v. For some time now it’s been showing a low battery reading of 24.7v even though the charge controllers show battery levels were at 27.8v. This week it’s announced low battery at 21v and shuts down inverter, charge controllers show full levels and bms shows all cells at 3.42v average. I remember that cutting r14 I think fixes over volt problems but I wonder if someone knows if there might be some way to adjust this. Is it possible that the charging lcd meter is signaling the control board to shut down?

Any thoughts guys. This Pj was sold as an off grid set and not many sol either but everything else inside is the same.

Thanks
