JFY inverter models repair guide
This repair guide for JFY solar energy system inverters aims to assist troubleshooting. It’s not intended to be a comprehensive user guide.
JFY inverters are classified into three categories, namely the on-grid, off-grid, and pumping inverter. An on-grid inverter is typically connected to the public electricity grid, while an off-grid inverter requires a battery bank to function efficiently. On the other hand, a pumping inverter converts the direct current (DC) of the solar panel into alternating current (AC).
You can check for the model of your JFY solar inverter by referring to the list below:

- 220V Single-Phase 550W-22kW
Signs That Your Solar Inverter Needs Repair
Two of the most common signs that indicate a problem with your solar inverter and that it needs repair include a fault light, as well as an error code. There are even instances wherein your inverter shows no lights at all, or it just suddenly stops working. It is in this instance where we can be of help. At Service Tech, our team of expert solar electricians will be able to check your solar inverter, have it repaired or replaced immediately.
What to Do if You See a Red Alarm Light
You may notice that the red alarm light of your inverter is on while its screen is blank. This means that the inverter fails to produce any power and it needs to be checked by a seasoned electrician. However, there is also the option for you to try a solar power system reboot.
To perform the shutdown procedure properly, make sure that you power down the solar supply main switch or the inverter AC isolator if you have this installed. From there, you need to turn off the PV array DC isolator which you will find in the inverter.
After about a minute, turn the solar supply main switch back on or the inverter AC isolator. You also have to power up the PV array DC isolator in the inverter after. You may need to wait for a few minutes for your inverter to restart. After this, check whether the red alarm light is no longer on and your screen is no longer blank.
How to Resolve a Fault Error Message
System Fault Error Codes:
- W01 – Grid connection issue
- W02 – Vin over-voltage
- E01 – Isolation error
- E02 – Leakage current too high
- E03 – Grid fault
With a system fault, you may see error codes W01, W02, E01, E02, or E03 on the display. You may also see an auto test failed message. These error codes may indicate that there is no grid, a PV panel voltage, or a leakage current that is too high, an insulation problem of the PV panel, or a grid or voltage frequency that is out of range.
Inverter Fault Error Codes:
- E04 – Coherence error
- E05 – Over temperature
- E06 – Relay failure
- E07 – Output current DC offset too high
- E08 – EEPROM failure
- E09 – Communication failure
- E10 – DC bus over-voltage
- E11 – DC bus under-voltage
- E12 – Vref error
- E13 – DC sensor fault
- E14 – Damaged GFCI device
Under an inverter fault, you may see error codes from E04 to E14. These codes indicate a consistent fault, an abnormal internal temperature, an output relay fault, as well as an output current DC that is too high. Conversely, these codes can also mean an EEPROM or communication fault, as well as a DC bus over or under voltage. It can also be that your inverter is encountering a reference voltage or a DC sensor fault or worse, the GFCI device is damaged.
If any of the problems above persist, better gather some information about your inverter’s installation date, model number, as well as its serial number before you get in touch with a serviceman. If your inverter was installed within the last five years, then there is a great chance that it is still covered under warranty. Otherwise, perhaps it will be better to have it replaced with a new inverter that is covered with a full warranty.

The cost of the repair can be as low as $80 if it is simply a matter of replacing an external plug, switch or consumable part and it isn’t necessary to remove the inverter.
Standard workshop repair costs range from $195 to $495 – Please note there may be additional site visit fees applicable.
We provide a full range of solar inverter replacement options if repairs are not possible.
You will need to review your insurance policy details to determine if coverage is applicable for your solar system damages. If you’re not sure, contact your insurance company for clarification.
If required we can identify the cause of damage to the solar inverter by conducting a workshop-based electrical component forensic investigation and report.
To find out if your inverter is covered under warranty, first establish when the warranty period began. This is generally the date the system was installed.
The most common inverter warranty period we see is 5 years. However we recommend checking your paperwork as extended warranties are not uncommon and some manufacturers offer up to 10 years – we can assist you with the manufacturer warranty claim process.
Don’t worry. This information is available from your local electricity generator, which is Energex in South East Queensland, Ergon in North and regional Queensland and Essential energy for Northern New South Wales.
It looks like your options are limited and your inverter will need repairing or possibly replacing.
