When my LiFePO4 DIY ESS battery pack is depleted, at 24V, the programmable voltmeter's low limit relay opens, the contactor opens, and the Grid Tie Inverter mode is shut off (low red led ON); This is what happended here
Immediately, the pack voltage goes back up and settles down around 25.4V
Now in the morning, for testing purposes, I siwthed the ESS to Forced Charge Mode, and all the chargers then are charging the battery pack
Since I can not stay all day next to it, I usually leave Karotz watch it for me and take a look remotely from time to time while away from home
08:20
At work

it then continues and goes up pretty quickly after 27.5V to 28V where the upper limit voltage is reached and the programmable voltmeter opens its other relay, opening the charger side contactor, and terminating the charge completely
and the total Enegry used to charge fully the pack is 5kWh
