Faults Diagnosis and Solutions
Grid Faults
-Waiting for one minute, grid will go back to normal working
state.
-Making sure that grid voltage and frequency complies with
standards.
-Or, please seek for help from us.
No Utility
-Off to grid.
-Please check grid-connection, like wire, interface, etc.
-Checking grid usability.
-Or seek for help from us.
PV Over Voltage
-Checking the panel’s open-circuit voltage whether the value is
similar or already >Max.DC voltage.
-Please seek help from us when voltage ≤Max.DC voltage.
DC INJ High
-DC injection is higher than the set value.
-Wait for one minute.
-Please seek for help from us if it does not go back to normal
state.
SCI Failure
-Disconnect PV (+) , PV (-) with DC input, and re-connect them.
-Please seek for help from us if it can not go back to normal state.
DC Sensor Fault
-Disconnect PV (+) , PV (-) with DC input, and re-connect them.
-Please seek for help from us if it can not go back to normal state.
Isolation Fault
-Check the impedance among PV (+)、PV (-) and ground.
SolarRiver 1700TL~SolarRiver 5200TL>1Mohm .
-Please seek for help from us if it can not be detected or the
impedance value is not big enough.
Consistent Fault
-Disconnect the PV (+), PV (-) with DC input, then reconnect
them.
-Please seek for help from us if it can not go back to normal state.
