Recently my motorhome's Lifepo4 battery doesn't get charged via solar past 13.1v. Normally it's fully charged at 13.35v. Under load the Epsolar (Epever) Tracer doesn't charge either. Even though I put a load of 14 amps on it. I see there's no charge load on the BM-1 battery monitor and the MT50 monitor from the MPPT charger.
Measuring the MPPT in and out ports with a multimeter shows that the solar panels do provide approx. 13.7v (as is float voltage set in the Tracer). The voltage going out of the Tracer MPPT is 13.1.
Does this mean that the MPPT is the culprit and it simply doesn't put out more than 13.1v anymore or can it also be something with the shunt, the battery itself, or something else?
I checked for corroded connections etc on the shunt but all seems okay. If someone could please help me find out what's going on, would really appreciate it.
