I am currently running a non-Victron integrated MPPT/inverter together with 2x 3.5kWh Pylontechs and 9 panels. I have a Raspberry Pi solution in place that connects both to the inverter and the Pylon BMS and controls the inverter modes according to the BMS SOC (rather than voltage reading).
As the built-in MPPT is of older generation, I am now contemplating adding a Victron MPPT 250/85 to the system and moving my panels (and using my current unit purely as inverter).
What I do not fully understand yet is if I need to establish some form of communication between the Pylon BMS and the Victron MPPT? I've read about VE.Smart Networking but do not understand what the benefit of adding a BMV (or SmartSense) would be.
Can anyone here please help me understand?
Thanks in advance
