Hello,
I have a Battery Bank of 4 brand new Victron 90Ah AGM Deep Cycle Batteries connected in serial for 48V. They are charged primarily by a Victron MPPT.
I get an error everyday from Venus (BMV702), stating that the Midpoint Deviation exceeds 3.4%.
Is this OK? What is the maximum acceptable midpoint deviation in a 48V Victron AGM Battery Bank?
Thanks,
Markus
