I have 2 x 5Kw Deye inverters connected in parallel, with 2 Deye 6.14Kwh batteries and 21 470W panels.
SmartLoad works fine, but I can't set SmartLoad to activate if the battery COC is less than 100%. (I can however adjust the cutoff COC from 95% down)
In the morning, when the batteries are charging (at 3-4Kw), it typically takes about 2 mins to increase the COC by 1%.
However, once the COC reaches 99%, the charge rate drops to below 1Kw and it takes 30mins to go from 99%->100%, when (finally) the SmartLoad activates. I assume the BMS cuts the charge rate as the batteries reach full capacity.
SmartLoad runs my pool pump, so I'd like it to start once the battery COC reaches 99%.
