EV chargers integration
ABB Terra AC, smartly controlled
The ABB Terra AC is a widely used AC charger for businesses. Voltmasters EMS controls the unit, does load balancing within the grid connection and plans charging at the cheapest moments.
Supported devices
- Terra AC
What the EMS gets out of your ABB installation
- Load balancing within the limit of the grid connection
- Charge at the cheapest moments, including negative prices
- Priorities per charge point, the fleet comes first
- Interplay with battery and PV for extra charging power
- Monitoring of every charging session
Why installers combine ABB Terra and Voltmasters
Charge points are added on top of a connection rarely designed for them. The EMS distributes the available power across the Terra AC units, the battery and the PV and plans charging smartly, including negative prices. The main connection stays within its limit.
