7.11.6 Setting the Maximum System Power in kWp
The system power in kWp (kilowatt peak) is the maximum possible power of the PV system. You can
find out the value in kWp from your installer. The Sunny Beam requires the system power in kWp to
calculate the specific annual yield (kWh/kWp). The specific annual yield makes it possible to directly
compare PV systems of different sizes. The calculated specific annual yield indicates the energy yield
for a system size with 1 kWp of power installed.
The specific annual yield is one of the charts of the Sunny Beam
(see figure on the right). The Sunny Beam can display the system
performance for the last 20 years. The more years are included,
the more narrow the columns will be.
1. Select "Settings > PV plant > Plant power in kWp".
2. Set the system power in kWp.
☑ The system power in kWp has been set.
Requires data from January to December
The specific annual yield for one year is only representative if the Sunny Beam can use data
for an entire year. If your PV system with the Sunny Beam was commissioned in July, for
instance, data from the previous months are lacking. The present data (from July to
December) will then be projected to the entire year by the Sunny Beam.
Expanding your Bluetooth PV system
If your Bluetooth PV system is to be expanded with more PV modules, you need to set the
new system power in kWp on the Sunny Beam. The new inverters can be added to the
Sunny Beam by performing a new system search (see section 7.11.3 "Repeating the
System Search" (page 60)).
