I have a BVM712 Smart, that is transmitting Battery Voltage and Current sense. And I have a Smart Solar MPPT 150/85 that is receiving Battery Voltage and Current. The are in the same VE.Smart network. Firmware of the BVM is 4.12 and the firmware of the MPPT is 1.61
I have set the Max Charge Current in the MPPT (settings menu: Battery) to 26 A to make sure my battery is charged at 1C (my battery bank is 260 Ah).
When I look what happens now, is that when I have a load of 10A, the battery wont charge higher than 16A. With a load of 20A, only 6 A is charged into the battery.
This means that this setting is limiting the charger output instead of the battery input as provided by the BVM712.
I think this is a bug in the MPPT firmware.
As the setting clearly says "Max CHARGE current", and the charge current is provided by the BVM - the current measured by the MPPT itself is the charge current + load, so it should use the BVM value instead.
