"BlueSolar Charger MPPT 100/30" in error?

View of two devices, BMV-712 and BlueSolar 100/30, in VRM dashboard


The number on the left are correct, I checked voltage at battery. The solar charger currently has 84vdc @ .27a going to it, should be producing about 23 watts? Solar charger seems to have incorrect state of battery, so not applying charge. Any ideas?

The battery is in float as far as the mppt is concerned and i suspect the current battery voltage is higher than the float voltage setting so zero amps coming from the mppt unit. check the battery settings in the MPPT unit.


check the voltage at the mppt controller and compare to the battery at the battery with a good voltmeter.

keep in mind that the vrm is updated from time to time ie depending on your update settings

the solar charger does not have a SOC read out
