Entering the PV Array Power


The PV array power is the maximum power of the PV modules connected to one PV inverter.

You can calculate the PV array power via the string properties Configuring Strings) or enter it manually.

SMA recommends calculating the PV array power via the string properties. A string describes a group of series-connected PV modules. Normally, a PV system is made up of multiple strings. Each string has specific properties, such as deviation to south (azimuth) or the roof tilt angle.

Entering the string properties provides the following advantages:

  • Sunny Portal can determine the PV array power more precisely.

  • The Sunny Home Manager can deliver more exact yield forecasts and control loads more efficiently.

You can find out the connected PV array power present on each inverter from your installer. Using the PV array power, Sunny Portal can calculate your nominal PV system power.

Nominal PV system power required for limiting active power feed-in

You must enter the PV array power correctly to ensure limitation of the active power feed-in to the correct value. If there are changes to the installed PV array power, you will need to adjust this value.

Procedure:

  1. In the area Generator capacity, enter the PV array power in the field kWp.
  2. Click on [Save].
