Hi everyone, I have a b box pro 13.8 with a sunny island 8 and 2 sma 5 inverters, all only 1 year old, system was running really well when we moved into our new house, generator came on a couple of times when battery hit 30%, and to took about 2 hours to fully charge, but for the last month the Genny has been coming on roughly 4_6 times per 24 hours, only running for 20 minutes and sunny portal shows the battery is fully charged??? We are only drawing roughly 300wh in the evenings so the battery should last time until the morning, anyone else had issues similar?
