I have (or at least had, as it is in service right now) an Easy-Solar 48/5000 system. I chose the internal battery monitor of the unit as I had no dedicated monitor (like BVM 700) at hand.
I found out that the colour control keeps reporting 100% SOC as the voltage varies within wide limits, between 48 volts and 55 or so, but the SOC never changes. Is this intended behavior or is something in the setup to be changed?
