Check the observed values against those
displayed in the portal. (if either CT1 or CT2
reads 0, one of the CT's is likely backwards.)
16. System check
The following commissioning protocol will
ensure all aspects of your storage system are
working as expected.
1. Verify that the batteries are at 100% SOC
and that the solar inverter is producing good
power.
2. Shut down the grid feed into the storage
system.
3. Verify the automatic transfer switch
switches over to micro-grid.
4. Verify all protected loads are being powered
by the storage system.
5. Verify the frequency shift occurs and grid
tied PV inverter shuts down.
6. Allow the state of charge to drop to 89%.
7. Verify the storage system resets the
frequency to 60 Hz and the solar inverter
restarts.
8. Monitor the SOC with solar contribution
and verify that when SOC reaches 95% the
storage system frequency shift occurs and
the grid tie inverter shuts down.
9. Restore the grid feed in to the sonnen.
10. Verify the automatic transfer switch
switches back to grid (5 minute UL-1741
required wait).
11. Verify the solar inverter restarts.
12. Verify all protected loads are operational.
13. Verify generator auto-start function by
disconnecting the breaker from the grid and
PV, and adjusting the minimum SOC above
the current level.
14. If using manual generator start, check
functionality by disconnecting the breaker
from the grid and PV, and manually starting
the generator.
