Trouble Shooting

In most situations, the Inverter requires very little service. However, if Inverter is not
able to work perfectly, please refer to the following instructions before calling your
local dealer.
Should any problems arise, the LED on the front panel will be red and the LCD displays
the relevant information. Please refer to the following for a list of potential problems
and their solutions.
SYSTEM FAULT
Ground I Fault
1. The ground current is too high.
2. Unplug the inputs from the PV generator and check the peripheral AC system.
3. After the cause is cleared, re-plug the PV panel and check PV-Inverter status.
4. If the problem persists please call service.
Isolation Fault
1. Check the impedance is between PV (+) & PV (-) and the PV-Inverter is earthed.
The impedance must be greater than 8M.
2. If the problem persists please call service.
Grid Fault
1. Wait for 5 minutes, if the grid returns to normal, PV-Inverter automatically restarts.
2. Make sure grid voltage and frequency meet the specifications.
3. If the problem persists please call service.
4. Check grid usability.
No AC connection
1. Grid is not connected.
2. Check grid connection cables.
INVERTER FAILURE
PV Over Voltage
1. Check the open PV voltage; see if it is greater than or too close to 450VDC.
2. If PV voltage is less than 450VDC, and the problem still occurs, please call local service.
Consistent Fault
1. Disconnect PV (+) or PV (-) from the input, restart the PV-Inverter.
2. If it does not work, call service.
If there is no display on the panel, please check PV-input connections. If the voltage is
higher than 90V, call your local service.
During periods of little or no sunlight, the PV-Inverter may continuously start up and
shut down. This is due to insufficient power generated to operate the control
circuits.
