Hi,
I have batteries that are charged through solar and DC2DC. Recently the DC2DC has been going into absorption before the solar and reading the battery voltage as around 0.1v higher than the smart shunt and the MPPT. Both chargers are set to AGM spiral per seller guidelines, I can't seem to find direct manufacturer technical specs.
Is there anything that could be causing this discrepancy, I have checked the wiring and it's all firmly in place. The breaker was recently switched off by a falling box while driving but still flips on and off as usual. All pieces of kit are fully updated.
Many thanks,
Laura
