5.5.3 Function Test
To test whether the SMA Power Balancer is operating 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 power distribution grid normally.
☑ Green LED glows continuously, or you see the
display message on the right: Proceed to step 3.
or
☑ If all the inverters in this group are displaying the
message on the right: check installation of the
SMA Power Balancer and contact the
SMA Service Line if necessary.
3. Switch off the miniature circuit-breaker in 1 of the
3 inverters.
• The inverter with the deactivated miniature circuit-
breaker will then indicate a line voltage fault by the
display message pictured on the right
("Bfr" and "Srr" are irrelevant).
• The other 2 inverters will then also disconnect from
the power distribution grid, showing the display
message pictured on the right.
• Both inverters subsequently switch to "Balanced"
mode.
☑ If the inverters react as described above, the
function 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 function test is complete.
