I freshly installed a BMV712 with included shunt, Smart solar 150 and a battery protect 100A in my remote cabin. 2 x 6 V 190Ah AGM batteries, as 12V in series. All running the latest firmware. Charging works pretty well with the two panels, the fast MPPT seem to be way better than the one of the old charger I replaced.
However the BMV Amp reading is approx 50% off, I.e. half of the true value. Whilst the A reading of the Smart solar is correct.
Interestingly the Smart solar receives the Amp from the BMV via VE Smart Networking.
I am wondering if this 50% deviation is related to the fact that battery flooring level is set to 50%? maybe a SW bug?
