I have a “Blue Power MultiPlus 48/5000/70 - Blue Solar Charge Controller – MPPT 150/35 - BMV 700 Battery Monitor. My system worked without ANY problems from, 24 Nov’18, until, 5 Apr’19 (131 days), throughout one of the worst winters in Crete, Greece. Since the arrival of beautiful sunny weather, a problem started. Green LED (Inverter ON) to Orange LED (Charger Float), since 5 Apr’19 until now 16 May’19 it has happened 8 times. Sometimes if I switch the Inverter OFF-ON it comes back on. Sometimes this solution takes Hours/Days. P.S. I have NEVER connected my generator Lowest Voltage = Zero, Highest Voltage = 58.2V I have 4 x 200Ah batteries ....
sorry it is taking me some time to navigate around
