Victron VE.Bus Smart Dongle

The VE.Bus Smart dongle is two products in one:

It is the Bluetooth accessory for Victron Energy's range of inverter/chargers: Multis, MultiPlusses, MultiPlus-II, MultiGrid, MultiGrid-II, Quattros, and Phoenix Inverters with a VE.Bus port. When installed, you can use the VictronConnect App to monitor operation and also operate the system: change the input current limit as well as switch between Off, On and Charger-only modes.

Secondly it can work as a Voltage- and Temperature-sense device for the inverter/charger. This works with all inverter/charger models.

For monitoring and making a few adjustment to input currents, this device is a great alternative for very simple systems (camper vans, smaller yachts and motor homes) that don't have a display for controls.
