PV over
Voltage
1. Check the open PV voltage, see if it is greater
than or too close to 500V (450V for CPS
SC1.5KTL).
2. If PV voltage is less than 500
V

,) 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
Over
Temperature
1. The internal temperature is higher than
specified normal value
2. Find a way to reduce the ambient temperature.
3. Or move the inverter to a cooler environment
4. If it is not effective, call local service

PV (+) or PV (-)
2. Wait for few seconds
3. After the LCD switches off, reconnect and
check again
4. If the message reappears call your local
service
If there is no display on the panel, please check PV-input connections.
If the voltage is higher than 150V, 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.
