I have a multi/mppt ESS setup that runs on a schedule with a 75% hard SOC limit and a stop at 80% SOC in the schedule.
Due to load the SOC hit 75% within a couple of hours during the night and reverted to grid as expected.
The inverter state was "float".
The inverter at no stage changed from float to bulk/absorption so when charging started it worked it's way to 80% and stopped.
Despite tons of PV available it trickle charged all day to a rather miserable SOC.
Any insight into why the inverter did not change to bulk/absorb?
We have identical installs and they all behaved correctly.
