The mains voltage is<br />
higher or lower<br />
than the authorised<br />
amount.<br />
The mains frequency is<br />
higher or lower than the<br />
authorised amount.<br />
Under or over-voltage of<br />
the DC input.<br />
1. Wait 5 minutes. When<br />
the mains supply be-<br />
comes normal again,<br />
the solar inverter<br />
starts up automati-<br />
cally.<br />
2. Check the mains connection<br />
(cable and<br />
terminals).<br />
3. Make sure the mains<br />
voltage and frequency<br />
meet the requirements.<br />
4. If the error still occurs,<br />
please contact your<br />
dealer.<br />
1. Disconnect all PV(+) -<br />
or PV(-) connections.<br />
2. Check whether the PV<br />
voltage is higher or at<br />
500 VDC.<br />
3. If the voltage is below<br />
500 VDC and the prob-<br />
lem persists, please<br />
contact your dealer.<br />
