Setup is 3x 100ah lithium batteries. Everything is Victron equipment. BMV, BatteryProtect, Multiplus, OrionSmart, and MPPT.
Yesterday I kept my Van inside a factory for the day/night, and today I noticed I was unable to draw power from the battery. Checking the BMV, on the SOC I see it was reporting around 41%, and the Voltage was 10.4V. Checking the BatteryProtect for DC I confirmed it was receiving low Voltage and was in the inactive state. I don't have a Bluetooth for the inverter but the low voltage LED was on.
I wouldn't expect the voltage to drop at SOC 40%. Can anyone advise if this is expected?
A fews things to note, in my BMV history I noticed it said last time at full charge was a day ago, this is not true. I have not hit a full charge in since powering everything on. Could this be a problem? I'm still in process of Van build and haven't been able to drive it much or put it in the sun during the day.
It's been on for about a week with no issues. The SOC was averaging 55%-65% during the week.
