My new second hand boat I has 2 x 50W solar panels connected to the service battery bank through a 75/15 MPPT Solar Controller. There is also an MPPT Monitor and a BWV700 battery monitor, both are installed and working. Everything works well. Now I found a new unused Bluetooth Smart Dongle. I tried to plug it to the MPPT controller, but the Ve.Direct socket is already being used (I suppose by the MPPT Monitor). Where does the Dongle fit in this system? Where/how do I connect it?
