5.5.3 Testing the Functioning
To test whether the SMA Power Balancer operates correctly, proceed as follows.
1. Select the "PhaseGuard" setting of the "PowerBalancer" parameter for all three inverters.
2. Check whether all inverters in the group are feeding the grid normally.
☑ If the green LED lights up steadily or if the
display message pictured opposite appears,
proceed with point 3.
or
☑ If all inverters in this group show the adjacent
display message: Check the installation of the
SMA Power Balancer and contact the SMA
Serviceline if necessary.
3. Switch off the line circuit breaker for one of the
three inverters.
• The inverter with a deactivated line circuit breaker
then indicates a grid voltage fault with the display
message shown opposite ("Bfr" and "Srr" are
irrelevant).
• The other two inverters then also disconnect
themselves from the grid with the display message
shown to the opposite.
• Both inverters subsequently switch to "Balanced"
mode.
☑ If the inverters react as described above, the
functionality test has been completed
successfully. Otherwise, check the
configuration.
4. If applicable, reset the "PowerBalancer" parameter to the desired setting in all inverters.
5. Switch on the line circuit breaker again.
☑ The functionality test has been completed.
5.6 Communication
The inverter is equipped with a slot for communication interfaces in order to communicate with special
data acquisition devices (e.g. Sunny WebBox) or a PC with corresponding software (e.g. Sunny Data
Control or Sunny Explorer).
See the respective communication interface manual for a detailed cuircuit diagram and an installation
description for the interface.
