I have 2x Phoenix Inverters 48/5000 in parallel with 2x BlueSolar MPPT 150/70 to charge a BYD lith bank, The batteries was run to 95% flat and system switched off (this was during night time). Inverters and BYD and CCGX turned off, next morning MPPT still on and charging BYD bank, but system stays switched off. I have switched everything off and back on but system stays off. Any help???
