Battery

The battery is an energy storage device that keeps energy for later use. It is usually connected directly to an inverter. The inverter manages its regime and provides energy data.

The inverter delivering the energy data has to be connected to the controller, commissioned, and the following KNX objects provided:

• Active power: This is the actual power charged or discharged from the battery.
  Assign this KNX object unit with W or kW.

• Active energy charged to battery: It is the total cumulative energy charged to the battery.
  Assign this KNX object unit with Wh.

• Active energy discharged from battery: This is the total cumulative energy discharged from the battery.
  Assign this KNX object unit with Wh.

• State of charge: This is the actual percentage level of battery charge.
  Assign this KNX object type with scale (05.001 1-byte integer).

If KNX objects are available, map them in the Energy plugin as follows:

1. In your web browser, open the Energy plugin for your controller.

2. Click + at the bottom right corner > click Add equipment. The form for creating new equipment pops up.

3. Fill out the General tab of the form as follows:

   Title	Any name
   Power limit (W)	Alarm threshold (it is compared to Active power). 0 = The alarm is not set.
   Self-consumption	The attribute has to be checked.
   Reverse direction	Leave the attribute unchecked.

   NOTE: Leave Reverse direction unchecked. You will find later in the mobile application if the charging and discharging are correct. If not, get back to this attribute and check it.

4. Click the Objects tab and fill it out as follows:

   Kostal inverter example
   Active power	Active power.
   Energy taken (required for consumption calculations)	Active energy charged.
   Energy produced (required for consumption calculations)	Active energy discharged.
   Device status	Optional (the status will be displayed in the plugin). 1 = OK/ 0 = failure
   State of charge (05.001 (scale, 1-byte integer))	Battery charge level in %.

5. Click Save.

   
   

   The battery (Energy Storage System) appears on the equipment list.

6. Check the Energy Storage System (checkbox on the left) > click at the bottom left > click Add selected to room > choose to which room(s) you want the battery added.

   NOTE: Rooms have to be already created in Touch Config.

7. Click Add.

The mapped battery power and energy are available in (new tab) at the bottom right of the mobile application.

Tap in the app and check if the battery is monitored correctly:

• The power values in a Live view have to be displayed instantly.

• You need to wait for data history and let the system generate enough data to display in the app.
