Hi,
Could anyone help me or providing me with tutorial on how to calibrate my EPever voltage reading?
I just installed my PV in January 2022. Just recently (appr. three days), I noticed my SCC gave me a high battery voltage reading. This resulted in my SCC stopped from charging the battery. At first, I thought this SCC MPPT was awesome and charging my LiFePO4 battery very fast. However, I checked the amount of energy it delivered to my battery was of small amount (less than 1 kWh while actually my battery was discharged deeply the night before). So I got my AVO meter to check voltage at the battery terminals. Shockingly, the voltage discrepancy was around 4~5 volt. I have checked my connection, all bolts are tight.
This is my measurement.
Battery terminals = BMS terminals = 24.46 volt
SCC Battery terminals = 24.43 volt
SCC software/displays and RS485 = 29.2 volt
Thanks.
