or can I use a BMV 702
asked
do I need a BMV-712 with a Smart MPPT 100/50
@jdviescas, the BMV and the MPPT are two separate, standalone devices and don't communicate with each other unless you're wanting to set up a VE.Smart Network between them. If you are trying to set up a VE.Smart Network, then you either need the BMV-712, as it has bluetooth built-in, or the BMV-700 or-702 with a compatible VE.Direct Bluetooth Dongle.
If you're not trying to network the two devices together, however, you can use any battery monitor you like, though I always recommend the -712 because the bluetooth built-in makes initial programming and subsequent monitoring far easier.
