I have my Powmr-3k-24v inverter set to stop discharging batteries at 40 per cent and it has done that. A few times this year it would quickly dip to the high 20's and just as quickly recover when the load dropped. Last night it went down to 4 percent and stayed there until the sun came up. I have it set to charge on sun only. Is the inverter not behaving as it should by letting it get down so low? Do I need to do anything to make it resume it's normal operation? The grid power was injected at the proper discharge level to supplement the load requirements. Lifepo4 4 x 100ah batteries.
