Functionality Test - SMA SUNNY MINI CENTRAL 6000TL Installation Manual

SMA Solar Technology AG
5.4.3 Functionality 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 Sunny Mini
Centrals.
2. Check whether all Sunny Mini Centrals in the group
are feeding the grid normally (green LED glows
continually or display message shown to the right).
If this is the case, proceed to step 3.
If all Sunny Mini Centrals in this group show the
display message pictured to the right:
check the installation of the SMA Power Balancer
and contact SMA Solar Technology if necessary.
3. Switch off the line circuit breaker for one of the three Sunny Mini Centrals.
4. The Sunny Mini Central with a deactivated line
circuit breaker then indicates a grid voltage fault
with the display message shown to the right
("Bfr" and "Srr" are irrelevant).
5. The other two Sunny Mini Centrals then also
disconnect themselves from the grid with the display
message shown to the right. Both devices
subsequently switch to "Balanced" mode.
6. If the Sunny Mini Centrals react as described
above, the functionality test has been completed successfully. Otherwise, check the
configuration.
7. If necessary, reset the "PowerBalancer" parameter on all Sunny Mini Centrals back to the
desired setting.
8. Switch on the line circuit breaker again.
