Buried in snow, I remember that living in Utah years ago. Here in CA mine would be buried in rain, but it all ran off this morning.
I understand a bit fuzzy. But you have the hands on experience and understand the Victron device operation.
Now for the real nitty gritty of my understanding of BMV712 monitor relay programming:
I look at the device, read the manual, and for example contemplate entering a set point, say for the SOC relay (discharge floor). I set it at 20%. Instructions say if the SOC falls below this value, the relay will close. SO I wonder, after the relay closes for a SOC below 20%, if the battery is charged to greater than 20% SOC, will the relay open ? Then I see that there is 'Clear SOC' relay parameter that can be programed into the BMV712. When the SOC has been raised above this value, the relay will open (pending relay min closing time and relay off delay set points).
Then there is the general statement under relay settings paragraph heading- "Remark: thresholds are disabled when set to 0."
SO I guess I do need to specify the clear SOC point or the relay will never clear (open) once closed for a discharge floor event. Or do I need to set it to 0, 'thresholds are disabled when set to 0' if I do not want to specify the clear relay setpoint ?
I see that there are 'clear relay' setpoints for every type of 'relay' set point. So generally if I enter a setpoint for a relay, I need to also enter a clear relay setpoint or set it to 0 to disable the setpoint. Is that true ?
The Relay mode apparently can be set to 'DFLT' or 'CHRG'. I think 'DFLT' allows the use of all the relay set points to control the relay, and that 'CHRG' only allows the use of two relay control functions, SOC and LOW VOLTAGE to control the relay. I'll be using DFLT.
I think that the relay control settings (SOC, LOW VOLTAGE, HIGH VOLTAGE, LOW START VOLTAGE, HIGH START VOLTAGE) are all OR statements for relay control. Like parrallel circuits energizing a relay coil, any one of the parallell circuits can energize the relay. Is that about right ?
