If your KLNE SunTeams Solar Inverter isn’t working properly a fault message should be showing up on the inverters display. Below is a list of KLNE Sunteam inverter error/fault messages, their causes and potential remedies for these faults from the KLNE SunTeams Solar Inverter user manual.
If you have any uncertainties in carrying out the remedies listed below we highly recommend you seek professional assistance from a local solar accredited electrician to avoid any risk of further damage or injury.
Stop power supply from the grid;
AC circuit breaker is disconnected; The both sides of AC circuit breaker are in poor contact.
|Idenitfy whether the grid stops power supply;
Identify whether the AC circuit breaker is closed;
Identify whether the breakover of the two terminals of AC circuit breaker is good;
If there are no above problems, please contact your distributor or customer service department.
The grid voltage exceeds the scope prescribed in the local regulations.
|When reporting error, check whether the grid voltage of the inverter is within the range prescribed in local regulations; Report this problem to the distributor or customer service department.
The grid frequency exceeds the scope prescribed in the local regulations.
|Whether this problem is always existing or intermittently existing; Report this problem to the distributor or customer service department.
The ground wires at the AC terminal are in poor contact.
|Check whether the ground wire of AC is in good contact; If there is no problem, please contact your distributor or customer service department.
|The actual voltage at the DC side exceeds the specified range of the inverter.
|Check whether the actual voltage at the DC side is within the specified range of the inverter; If complying with the range of the inverter voltage, please contact the distributor or customer service department.
|The possible cause is that there is leakage at the AC side.
|Disconnect the circuit breakers at the DC side and AC side and check whether there are damages to the cables and circuit breakers at the AC side.
|The ambient temperature of the inverter is too high.
|Idenitfy whether the ambient temperature is abnormal; Identify whether the inverter has sufficient heat dissipation space; Identify whether cooling fin of the inverter is blocked; If the external environment is normal, please contact the distributor or customer service.

You may view the full information on KLNE SunTeams solar inverter manual’s troubleshooting section. If following the steps above does not fix the issue and your KLNE SunTeams Solar Inverter is still within the warranty period, unfortunately the KLNE subsidiary in Australia had now been placed in liquidation and any warranty is no longer being honored.
It may be best to get a replacement unit should the problem persist instead of having it repaired where you pay more than $500 and still be left with an inverter of inferior quality without warranty.
