About The PV inverter shows that the AC voltage is too high
Turn OFF the inverters in the site and verify AC grid voltage. If the inverter is located far from the connection point to the grid, use a larger gauge AC wire. Consult the grid operator.

AC Voltage Too High - AC voltage surge. The internal hardware that measures AC voltage has measured substantially high sudden output voltage. If the fault persists: Check the AC connection to inverter. Verify that the inverter is set to the correct country.
Yes, I have measured the AC output under 1000watts loads with my RMS voltage meter and it's loaded down to around 124-125v. Wire from battery bank to Inverter is about 4ft, 2AWG, never get warm or hot. as the battery never is the main source power source, it's the charge controller/PV is the main source and the wire is 2awg and it's only .
The grid voltage is too high, even higher than in code 002: Check the AC cables model. Wait for the inverter to fix the error automatically. If it doesn’t, check that the grid voltage is within the acceptable range. If it isn’t, contact the utility grid company, but if it is, contact Sungrow. 016: The bus voltage or power is too high.
AC Voltage Too High (Line 1/2/3) AC voltage surge. If the fault persists: Check the AC connection to inverter. Verify that the inverter is set to the correct country. Check with the grid operator if a large surge source or irregular load exists near the site. Verify that the output wire size matches the distance between

6 FAQs about [The PV inverter shows that the AC voltage is too high]
What happens if a solar inverter is connected in a wrong way?
If the AC wire of the solar inverter is connected in a wrong way, the AC voltage overrange failure may be caused. If the phase wire and zero wire are connected wrongly, then the inverter A phase will show that the line voltage is 380V and the B, C will show that the phase voltage is 220V.
Why is my AC voltage too high?
Description - AC Voltage too high Behavior - Grid conditions are being tested and as soon as they are again within the permissible range, the inverter will resume feeding power into the grid. Troubleshooting - Check grid connections. If this status code keeps recurring, contact an installer/tech. Did you find it helpful? Yes No
How do I know if my inverter is working properly?
Check the GND connection. Check the L1, L2 and Neutral connections. Verify symmetric load between L1, and L2 . Consult the local grid authority. Grid voltage is above the country limit. Verify that the inverter is set to the correct country. Turn OFF the inverters in the site and verify AC grid voltage.
Why is my solar inverter causing a voltage rise?
The maximum voltage rise between your solar inverter and the grid is above the 2% maximum in the Australian Standard, because the resistance in the cable (including any connections) is too high. If this is the case then the installer should have advised you that your AC cabling to the grid needed upgrading before solar could be installed.
Why does my solar inverter have an AC voltage failure alarm?
Finally, if it is confirmed that the AC wire output terminal voltage is normal but the inverter AC voltage failure alarm still exists, the alarm may be caused by the internal sampling system of the solar inverter and users shall contact the inverter manufacturer to solve the problem.
What happens if AC voltage returns?
When AC voltage returns the inverter should restart after the reconnection time. If the problem persists, consult with the grid operator. AC grid voltage malfunction. When AC voltage returns the inverter should restart after the reconnection time. If the problem persists, consult with the grid operator. Contact SolarEdge support.
