Trouble Shooting - gefran RADIUS APV 1700-2M-TL Installation & Operation Manual

6. Trouble shooting
Note !
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 Fault 1. The ground current is too high.
Isolation Fault 1. Check the impedance is between PV (+) & PV (-) and the PV inverter is earthed. The
Grid Fault 1. Wait for 5 minutes, if the grid returns to normal, PV-Inverter automatically restarts.
No AC connection 1. Grid is not connected.
INVERTER FAILURE
PV Over Voltage 1. Check the open PV voltage to see whether it is greater than or too close to 500VDC
Consistent Fault 1. Disconnect PV (+) or PV (-) from the input, restart the PV inverter
Note !
If there is no display on the panel, please check PV input connections. If the voltage is higher than 150V, please contact your local
Service Centre.
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.

2. Unplug the inputs from the PV generator and check the peripheral AC system.
3. After the cause of the fault is cleared, reconnect the PV panel and check the PV inverter
status.
4. If the problem persists, please contact our Service Centre.
impedance must be greater than 8M ohm.
2. If the problem persists, please contact our Service Centre.
2. Make sure grid voltage and frequency meet the specifications
3. If the problem persists please call service
2. Check grid connection cables.
2. If PV voltage is less than 500VDC, and the problem stili occurs, please contact your
local Service Centre.
2. If it does not work, please contact your local Service Centre.
