So my setup been up running for a month now and first 3 weeks i got batteries recharged back to 100% every nigh. So last week i got more cloudy weather and was operating more on the lower half of battery capacity level. I have 2 x Growatt 500ES with 2 x JK BMS and 2 x 16s 280A batteries in parallel.
So last days i see quite allot of difference on the remain capacity on the batteries, 35AH at the most. I have try close the one battery to get both inverters to charge up the lowest capacity battery but what happens next when I turn back on the other battery Is that the battery who is bring back up now will get very less current and the other battery higher current so the gap between the 2 batteries will grow again. I see some higher voltage on the one battery pack and I see that On the inverter also.
I have no communication between inverters and BMS. Does the Inverters at any level manage charge and de charge levels between the inverters?
