1. Turn off DC/AC switch, and turn on DC/AC switch 10mins
later;
2. If the fault still exists, please contact us for help.
1. Loss of one phase or AC voltage detection part failure or relays
not closed;
2. Seek help from us, if can't go back to normal state.
1. Restart inverter and check whether it is in normal;
2. Seek help from us, if can't go back to normal state.
1. Check PV module connection;
2. Turn off the DC/AC switch and then wait 1~2 minute, then
turn on the DC/AC switch again;
3. Seek help from us, if can't go back to normal state.
1. Restart inverter and check whether it is in normal;
2. Seek help from us, if can't go back to normal state.
1. Check DC input power is within the allowed range;
2. Restart inverter and check whether it is in normal;
3. Seek help from us, if can't go back to normal state.
1. Please wait for a while and check whether it is normal;
2. If still same, and turn off the DC switch and AC switch and
wait for one minute and then turn on the DC/AC switch;
3. Seek help from us, if can't go back to normal state.
1. Check PV panels connection and restart inverter. This
problem is caused by the PV side usually;
2. If the fault still exists, please contact us for help.
1. Turn off the DC/AC switch and then wait 1~2 minutes, then
turn on the DC/AC switch again;
2. If the fault still exists, please contact us for help.
1. Check AC grid voltage;
2. Check whether the AC output connection is in good
condition;
3. If the fault still exists, please contact us for help.
1. Wait for inverter to return to normal;
2. Disconnect DC switch and AC switch, and reconnect DC
switch and AC switch 10min later to restart the inverter;
3. If the fault still exists, please contact us for help.
