ICSH7D - Internal CT Clamp Configuration

Optional CT Clamp Setup

The ICSH7D has the ability to dynamically control the charger based on the electrical load of the property, it can also be used to divert excess solar power to the car. An optional ICSCT can be purchased and connected to the terminals shown below.

 If a CT clamp is required to monitor the household load then 1 CT clamp is required. If solar is present in the property then it’s recommended to fit 2 CT clamps as shown in the diagram below.

7.1 CT Clamp Setup

First, log back into the configuration page instructed in Step 5.

Once logged in, select the ‘Balance’ Icon under the advanced tab.

Then select the mode as Master TCP Server, as shown below. Then click Next Step

7.2 CT Clamp Configuration

On this page, you can select whether or not solar is connected to the property. 

The GRID CT should be connected to the CT1 input,

The SOLAR CT should be connected to the CT2 input.

7.3 Grid Current Setting 

On this page the current setting is set up:

Rated Current—This is the current rating of the main incoming fuse, this is in 0.1A, so for a 100A fuse you would input 1000, as shown below.

Safe Current—This is a safety buffer of when you want to limit the charge current, For instance the below is set to 20A, this means once the properties current reaches 80A, the charge rate will start to reduce.

Limit Total Charge Current—This is used if multiple charge points are connected and it limits the group of charge points to a set limit. 

Energy Mode—This is used if the charge point is required to only charge from solar, this setting can be changed in the app.

7.4 Energy Server Setup

If the customer wishes to view the information of the CT clamps then the internal load management hub can be connected to the app. This can be added to the app by adding the ID—this is usually M_ and then the serial number of the charge point.
