BMV 712 discharge floor / SOC

Hi, I have 4 x 270 Ah AGM batteries in parallel / series giving 24 volt and 540 ah monitored with a BMV 712

I have the discharge floor set to 50% as I don't want my batteries to fall below 50%

I want this set up so the relay will activate my generator when the batteries fall to 50% charge

For this to be correct do I need to set the SOC to 50% also or does the SOC calculate its 0% to 100% from the discharge floor setting of 50%?

The discharge floor is only used to calculate the time remaining figure. See

For SOC 0% = completely empty regardless of the discharge floor value. Therefore you need to set your generator relay to come on at 50%.
