5.5.3 Function Test
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 into the electricity grid normally.
☑ If the green LED is glowing continuously or if the
display message shown on the right appears,
proceed to step 3.
or
☑ If all inverters in this group show the display
message shown on the right: check the
installation of the SMA Power Balancer and
contact the SMA Service Line if necessary.
3. Switch off the miniature circuit-breaker of one of the
three inverters.
• The inverter with the deactivated miniature circuit-
breaker will then indicate a mains voltage fault via
the display message shown on the right
("Bfr" and "Srr" are not relevant).
• The other two inverters will then also disconnect
from the electricity grid, displaying the display
message shown on the right.
• Both inverters subsequently switch to "Balanced"
mode.
☑ If the inverters react as described above, the
function test has been completed successfully.
If not, check the configuration.
4. If applicable, reset the "PowerBalancer" parameter to the desired setting in all inverters.
5. Switch the miniature circuit-breaker on again.
☑ The function test is complete.
