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 power distribution grid normally.
☑ Green LED glows continually, or adjacent
display message: Proceed to step 3.
or
☑ If all inverters in this group show the display
message pictured on the right: Check the
installation of the SMA Power Balancer and
contact the SMA Serviceline, if necessary.
3. Switch off the miniature circuit-breaker for one of
the three inverters.
• The inverter with a deactivated miniature circuit-
breaker then indicates a grid voltage fault with the
adjacent display message ("Bfr" and "Srr" are
irrelevant).
• The other two inverters then also disconnect
themselves from the power distribution grid with the
display message shown 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 miniature circuit-breaker again.
☑ The functionality test has been completed.
