Hager EV charger
The Hager Witty is a range of smart EV chargers. The EV charger is connected to the Currentt Navigator via Modbus RTU (RS-485) or Modbus TCP (Ethernet).
⚙️ How it works
The Hager Witty communicates via Modbus RTU (RS-485) or Modbus TCP (Ethernet) with the Currentt Navigator. The Navigator reads the charging data (such as charging power and charging status) and sets the maximum charging current of the EV charger. This way the charging current is continuously matched to the available capacity of the grid connection and to the current yield of the solar panels.
