hi did you manage to resolve this problem. i have a similar problem. Luxpower 5Kva and a dyness lithium battery 4800kw, 4 JA pannels of 475 each. my load is only a 100 watts fridge, and 15 LED lights of 9 watts.
the luxpower hybrid inverter just stops working almost every day after 10 pm, even when the battery is around 83%
can anyone help
