Isolation Fault
-Check the impedance between PV (+)
、
PV (-) and ground. For
1.5KW~T2.8KW >1Mohm, 3.3~5KW>2Mohm.
- Contact Tress Power if impedance value is not big enough.
Consistent Fault
-Disconnect PV +ve and –ve input, and re-connect after a short break.
-If fault persists, for assistance
Relay Failure
-Disconnect PV + ve and – ve input, and re-connect after a short break.
-If fault persists, for assistance
Ground I Fault
-Leakage current is too high.
-Disconnect DC and AC connector, check
equipment on the AC side for
concerns and rectify any faults found.
-Reconnect the DC input and check operation..
-If fault persists, for assistance
EEPROM Failure
-Disconnect PV + ve and – ve input, and re-connect after a short break.
-If fault persists, for assistance
High DC Bus
-Disconnect PV + ve and – ve input, and re-connect after a short break.
Check AC connection for faults
-If fault persists, for assistance
fan Fault
-Check the fan for any block .
-Check fan cables.
If fault persists, for assistance
GFCI Failure
-Disconnect PV + ve and – ve input, and re-connect after a short break.
-If fault persists, for assistance
9.2 Routine Maintenance
Inverters generally do not have any maintenance needs.
The cooling fan is fitted should not be blocked or covered in dust..
● Cleaning of Inverter
Use small electric blower, soft dry cloth or brush to clean inverters. Water, corrosive chemical, or
intense cleaning agents should not be used.
● Cooling fin cleaning
To ensure proper inverter performance, adequate space needs to be left all around the inverter and heat
sink at the
back. Fan should not be blocked by dust, snow or any other object. Use air blower, soft cloth or brush
to clean cooling fin. Water, corrosive chemicals or intense cleaning agents should not be used for
cleaning inverter or fan.
