January 23, 20242 yr 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.
January 26, 20242 yr @AttieW1Hi and welcome. You have a very nice system that sounds big enough for a commercial site. 24kw pv panels produces on average 120kwh per day but you only have 33kwh of battery storage. I'm guessing your system produces 33kwh by 9h30 which then begs the question what do you do with the +-90kwh that you could potentially produce? Edited January 26, 20242 yr by Buyeye
