Use your VE.Bus products with the VictronConnect app. Firstly, it is the Bluetooth accessory for the inverters and chargers: Multis, MultiPlus, MultiPlus-II, MultiGrid, MultiGrid-II, Quattros and the Phoenix inverter series with VE.Bus connection. After installation, use the VictronConnect app to monitor operation and run the system: Change the input current limit and switch between Off, On and Charger Only modes. Secondly, it adds voltage and temperature detection to the inverters and chargers. It works with all models and is especially useful in combination with the MultiPlus-II as it does not have inbuilt terminals for voltage and temperature sensor wiring. For monitoring, the device is a good alternative in caravans, smaller yachts and motorhomes for which the Color Control GX or Venus GX are uneconomical or simply not desired.
