Hallo,
If i look at the batterij percentage in the vrm tool there is a differentage between what the batterij say and the victron multiplus II.
Is there some way to adjust this? Now the victron say the is 9.5% precent butt there is 15% in the batterij and whan dischare anymore.
Cane i safely lower the percentage of the dischare to 5% in the setteings of the multiplus?
There will almost always be a difference between what SOC a victron shunt measures and what SOC a BMS measures, battery SOC is not an exact science.
Both the shunt and the BMS (probably) reset to 100% after the battery is fully charged and reaches certain voltages for a certain time. So most likely by fully charging the battery the SOC of both will be 100% and in sync. Then they get out of sync when discharging again most likely. As you can see in the screenshot one measures -0.6A and the other -0.5A, this already is a 20% difference.
You can either lower the minimum SOC in the vrm or select the BMS as main battery monitor.
This is safe as in equipment won’t be damaged if SOC gets too low. However the inverter will stop providing power when voltage is too low or the BMS gives an error.
