Solar Panels

Map this energy group only when a photovoltaic system is installed in the house.

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

• Active power: It is the actual power generated by solar panels.
  Assign this KNX object unit with W or kW.

• Active energy: It is the total cumulative energy generated by solar panels.
  Assign this KNX object unit with Wh.

A photovoltaic string is a separate set of panels connected to a DC port of an inverter.

If there are more strings of solar panels, there are two ways of mapping:

1. Single: If KNX objects are the aggregation of all solar panels strings, then the mapping procedure below is done just once to create a single photovoltaic equipment.

2. Multiple: Inverters allow the connection of multiple strings at the same time.
   Inverters handle multiple strings differently. Some manufacturers offer the total sum of photovoltaic power in one object and the total sum of photovoltaic energy in the other. Other manufacturers report values for each string separately, so there is photovoltaic power string 1, 2, etc.
   In the second case, it is necessary to commission as many pieces of equipment as the number of strings installed in the system.

   Photovoltaic strings	Energy plugin mapping
   1	One instance of photovoltaic equipment (power, energy).
   2, aggregated	One instance of photovoltaic equipment with power and energy values aggregated by an inverter.
   2, non-aggregated	Two instances of photovoltaic equipment: 1 (power 1, energy 1) 2 (power 2, energy 2) The system aggregates the values and displays sums in the mobile application.

If an object combines energy values from multiple photovoltaic strings and separate power objects of individual photovoltaic strings, then the energy object is assigned only to the first instance of photovoltaic equipment.

Example:

• Solar panels 1: Active power 1, Active energy All

• Solar panels 2: Active power 2, –

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).

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

   Kostal inverter example
   Active power	Active power.
   Energy produced	Active energy.
   Device status (1 Bit)	Optional (the status will be displayed in the plugin). 1 = OK/ 0 = failure

5. Click Save.

   
   

   The solar panels (Photovoltaic) appear as an item on the equipment list.

6. Check the Photovoltaic (checkbox on the left) > click at the bottom left > click Add selected to room > choose to which room(s) you want the photovoltaic added.

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

7. Click Add.

The mapped solar panel´s power and energy are available in the mobile application.

Tap in the app and check if the solar panels are correctly monitored:

• The power in the Live view has to be displayed instantly.

• For data history, you need to wait for the system to generate enough data to display in the app.
