Eastron Load Monitor with CT Clamp 0-100A

The Eastron Load Monitor with CT Clamp 0-100A is an optional energy meter that will allow advanced load balancing features on the Autel single phase chargers. The meter is installed at the switch board and communicates back to the charger via a data cable sending the total home load back to the charger. This will ensure the switch board is not overloaded. This can also be used with Solar generation to automatically adjust up or down based on the solar input so no energy will be exported to the grid while the car is charging.

Select from the following modes on the Charger:

• Dynamic load balance The charger and energy meter will monitor the total house draw. If this draw exceeds the maximum limit the charge rate will be reduced to avoid tripping the breaker. Most homes are rated to 63A. Car charging can use up to 32A. This mode is useful if multiple appliances are running simultaneously while the car is charging.
• Dynamic Load with multiple chargers The first charger is connected to the energy meter, the rest will communicate via WIFI/LAN back to the first charger to enable sharing of the total capacity.
• Solar Mode The energy meter can prevent excess solar going to the grid by automatically adjusting the charge rate of the car to use the excess energy. Select from 3 modes:
  • Full Green Mode: This will only use the excess power that is being generated by the solar. So if exporting say 10A to the grid then the charger will put the 10A in to the car. This will vary based on how much excess energy is being generated. A minimum of 6A is required to start charging an EV.
  • Green Priority: When in green priority mode the charger will ramp up and down based on how much excess would usually be exported to the grid. However in this mode, when the sun goes down or behind a cloud it will charge at the minimum from the grid as a top up. The minimum a car can charge is 6A.
  • Speed priority: This will ignore solar generation to top up the car as fast as the charger and car is capable of.

Installers' note: 

• This is a rail mounter energy meter and is installed by the electrician at the switch board
• The included CT clamp simply clamps around the incoming main cable
• A twisted pair cable is required between the meter and the charger - KNX Bus cable recommended.
