VE.Net stands for Victron Energy Network. It allows all VE.Net compatible devices to communicate with each other. This means that the charger for example can get information from the battery monitor to optimize the charge current. It is possible to control and monitor all your VE.Net devices from a single VE.Net compatible control panel. This saves space and allows you to control all your devices from one place
The VE.Net Battery Controller is a device that monitors your battery status. It constantly measures the battery voltage, battery temperature, and battery current, and uses this information to calculate the actual state of charge of your battery.
It is not a stand alone unit and is designed to be used with one of the Victron Energy VE display units. Compatible panels include the Blue Power Panel GX, the Blue Power Panel 2 and the Victron Color GX
