Grid voltage exceeds the
standard set in the inverter
1. Wait to see if the grid voltage returns within limits.
2. If problem persists, check whether the grid standard is set correctly in Advanced
Settings (see 6.6).
3. Check V_AC, grid voltage, in Information display of inverter (see 6.3) and
perform independent measurement of grid voltage to confirm that the inverter
reading is correct. If the measured voltage is outside the local grid standard
limits, please contact your local utility as it may require monitoring and
adjustment
4. With agreement from utility it is possible to set a user defined voltage range (see
6.6).
Grid voltage is below the
standard set in the inverter
Grid frequency exceeds the
standard set in the inverter.
1. Wait to see if the grid frequency returns within limits.
2. If a problem persists, check whether the grid standard is set correct in Advanced
Settings (see 6.6).
3. Check grid frequency, in Information display of inverter (see 6.3) and perform
independent measurement of grid frequency to confirm that the inverter
reading is correct. If the measured frequency is outside the local grid standard
limits, please contact your local utility as it may require monitoring and
adjustment.

1. Check your AC power connections and switches.
3. Call your local grid to resolve the black out.
