I have a Victron 100/20 MPPT. its connected to 2 x 100w solar panels in series.
It is only connected to my batteries and the load side is not connected. These are 2 new this year 115ah Halfords Leisure batteries.
Its been working fine charging my batteries with and without a load on those batteries. Then all of a sudden it starts to over read the voltage at 13.**v ), when my other volt meter (connected via a shunt) is reading 12.**v.
No matter what i do it wont read the correct voltage and just keeps the charging in "Float" so doesnt charge the batteries. If i do the cycle thing in the settings it then puts a charge into the batteries. This is also with everything disconnected except the panels as well.
The panels are working fine, and there is not issue with the wiring. Nothing physical change from when it was working till now. Is my MPPT fooked?
