VICTRON ENERGY ASS030537010, VE.Bus Smart Dongle is two products in one: First of all, it is the Bluetooth accessory for our series of inverters/chargers: Multi, MultiPlus, MultiPlus-II, MultiGrid , MultiGrid-II, Quattro as well as our series of Phoenix inverters with a VE.Bus port. Once installed, the VictronConnect app can be used to monitor operation and also control the system: change the input current limit and switch between off, on and charge only modes. It can also act as a voltage and temperature sensor for the inverter/charger. It works with all models. For monitoring, the device is an excellent option in caravans, small boats and motorhomes, where Color Control GX or Venus GX are a bit much.
