October 7, 20241 yr Hello everyone, I’m using a PowerMr 3600W DC 24V AC 110V Hybrid Inverter paired with a 24V 100AH lithium battery (8S). Here are my current settings: Charger Source Priority: Solar Only Load Output Priority: SBU (Solar, Battery, Utility) Comeback Utility Mode Voltage Point (SBU Priority): 21.5V Comeback Battery Mode Voltage Point (SBU Priority): 24V Low Battery Cut-off Voltage: 20V Bulk Charging Voltage: 28.2V Float Charging Voltage: 27.0V Given this configuration, I’m concerned that when the battery is depleted, the load should switch to utility, but it seems like the utility is charging the battery instead. Could someone provide feedback on whether my settings are correct or if adjustments are needed? Thanks!

Personally I think there is so little energy available from the battery come back at 21.5V to the cut out of 20V that I would lift both higher. I use about 24V as my cut out. This way my BMS should never switch the battery off.
