I am trying to get my BMV-712 relay to function as follows:
1) remain normally closed.
2) When the SOC drops below 20% (Victron Smart Lithium 150ah batteries), I would like the relay to open.
That would cause a generator / charger to start (beyond the scope of this question) and charging would initiate.
3) Once the batteries are charged so that the SOC is above 55%, I would like the relay to close again.
Here's what I've tried, with no success:
Use Victronconnect
Enter Settings/Relay
- Relay Mode: Charger
- Invert Relay
- Low SOC relay
- Set value 20%
- Clear value 55%
I consulted the manual and it said that I needed to set "Clear Low Voltage Relay" and I tried to set that to 1.1v and that did not help.
What settings so I need to enable to allow the relay to be normally closed, open when SOC drops below 20% and closed again when SOC goes above 55%? Thanks!
