Good day everyone I have 2 x 12kw Sunsynk 3 Phase inverters with 24kw panels on the roof and 3 pairs x 11.2kw Revov 2nd life batteries each with its own BMS. Sometimes (especially when the PV's goes over 19kw) the PV's Kilowatts will drop to zero or just about zero. That happens even with bright clear skies. I have checked the Temp of the inverters when the drop happens and it is not that hot, around 52-52 degrees Celsius. The installers thoughts were that it is because of an in-balance of the batteries, but after replacing the BMS's and even adding a 3rd 11,2kw Revov second life battery(I originally only had 2 x 11.2kw batteries), it still happens from time to time. After about 15 minutes of no PV, it will start producing PV power again, just to drop to zero PV after 15 minutes. This happens a few time a day and it happens not every day, sometimes it will run perfect for days on end. Any suggestions will be highly appreciated.
