How is the percentage battery capacity calculated on the Victron Connect and how often is it being updated? I have a new installation with a Victron Multiplus and Cerbo CX with a MicroCare MPPT (South African product) and, although the voltage is shown correctly on the Victron Connect, the percentages are, as far as I am concerned, completely wrong. This causes the system to function incorrectly, as far as I am concerned. With the batteries (Lithium Phosphate) almost fully charged, the percentage charge is shown as 20% causing all the power consumption to be fed from the grid.
The MicroCare MPPT has a RS485 output and if I could find out how to incorporate that into the Cerbo CX, it may help.
