I have a DIY system that runs off MPP Solar LV2424 inverter with 2x 100AH LiFePo4 batteries in 2S1P configuration. They are fed by 4x 200W solar panels. The system is pure off-grid and there is no utility service to the shed. I am observing that once the battery is discharged, the inverter shuts down and will not start charging the batteries until the batteries are charged to some degree even when it is sunny outside. I set the inverter to battery priority and AC cutoff to 23V so that there will be reserve on cloudy days. Is there any other settings I need to change so that the inverter will charge the battery when the sun comes up after going into DC cutoff?
Appreciate in advance for any suggestions.
