Troubleshooting Phasing Issues
If the Sol-Ark screen shows Grid Phase Wrong, there is a phasing issue with your wiring, and it may cause overload faults
(F18, F26, F34) even with the Load breaker off and WILL CAUSE DAMAGE if left unchecked.
Single Sol-Ark: To locate the improperly wired phases, measure L1 to L1 (Top Screws) between the Grid and Load
breaker; you should see 0V AC. Repeat for L2 to L2 between the Grid and Load breaker. Attempt to correct the wiring
until you are only reading 0V AC between L1 to L1 & L2 to L2.
Parallel inverters: measure L1 of the Grid breaker to L1 of another unit's Grid breaker; you should see 0V AC. If in 208V
parallel, measure the lines of the same wire color between sol-arks to see if you read 0V AC.
Make sure to correct both the Grid and Load wiring; they both need to be correct.
If the error persists, you will need to check your AC wiring beyond the inverter and may also need to verify that the
phases are properly labeled coming from your meter.
