Orion and SEA inverter repairs, monitoring and servicing

About Orion inverters

Orion inverters have been installed in Australia since as early as 2008. The most common model installed is the 2kW model. Some of the early models only came with a three-year warranty, but the majority came with a five year warranty. As such, many Orion inverters installed across Australia are already out of warranty.

No Utility Fault

If your Orion inverter develops a ‘No Utility’ fault, it means there’s an issue with the AC (or grid) feed to your inverter. We recommend you check that the main solar supply switch in your switchboard is on. It may well be that your isolators are the issue or that a fault has occurred in your switchboard. Booking a health check with our service team will help diagnose the fault. In the event that the more common fixes do not rectify the issue, it’s very likely your inverter will need to be replaced.

Will my warranty or household insurance policy cover a No Utility fault?

It’s highly likely that the warranty on your Orion inverter has already expired. However, depending on your individual insurance policy, you may be able to claim some of the costs associated with replacing your faulty inverter on your household insurance. If you need assistance submitting an insurance claim, don’t hesitate to contact us, we’re more than happy to help.

What’s the best way of resolving a no utility fault in my Orion inverter?

Step one is to get in touch with Solargain to arrange a solar health check. Our technicians will come to your home and diagnose the fault, and offer options for rectification. If the issue cannot be rectified, a replacement inverter can be brought to site and installed that very same day, eliminating the need for any secondary call-out fees. If the inverter does need replacing, we recommend replacing your faulty Orion inverter with a Growatt, Zeverlution or Fronius Galvo 2 inverter.

For more information about a No Utility fault or to book your inverter health check, contact Solargain on 1300 73 93 55 or get in touch with us online.

Isolation Fault

An isolation fault in your Orion inverter shows that your solar panels may not be properly isolated. If it only seems to happen after rain, it’s likely that it’s just water that is triggering the fault. If the isolation fault occurs constantly, regardless of moisture in the environment, further investigation should be conducted.

The best course of action is a solar health check with Solargain. We’ll look for signs of water ingress and test for any isolation faults. Where possible, we’ll repair the fault; however, if repair is not possible we can replace the faulty unit with a new inverter that very same day.

Is an isolation fault covered under my Orion inverter’s warranty or by my home insurance policy?

It’s unlikely that your Orion inverter will still be under warranty; however, you may still be able to replace it under your household insurance, depending on your individual policy details. If you need assistance making an insurance claim on your faulty inverter, we’re more than happy to assist you.

How do I resolve an isolation fault in my Orion inverter?

When you book a Health Check with us, our experienced technicians will diagnose the fault and make any necessary repairs (please note additional fees may be incurred if alterations to the installation are required). In the event that your inverter cannot be repaired, it will need to be replaced. In this case, we recommend you replace your faulty Orion with either a Growatt, Zeverlution or Fronius Galvo 2 inverter. We always have our technicians bring a replacement inverter with them in the case this should be required.

Relay Failure

If your Orion inverter is indicating that it has experienced a relay failure, this means a component inside the inverter itself has failed. Without this component, the inverter cannot function and produce electricity.

We recommend you contact Solargain to arrange a health check in order to confirm the nature of the fault. If a permanent relay failure has occurred, the inverter cannot be repaired and will need to be replaced. Fortunately, we carry suitable replacement inverters with us, so we can switch out the faulty unit and replace it with a new one, all in one day.

Is a relay failure fault covered under Orion’s warranty or under household insurance?

Given that the warranty on your Orion inverter has almost certainly now expired, it is unlikely you’ll be covered by warranty. However, the cost of rectifying an inverter relay failure may be covered by your household insurance policy. We recommend that you contact your insurer to confirm your policy coverage and, if you need help making an insurance claim, contact us so that we can help.

What should I do about a relay failure fault in my Orion inverter?

Step one is to call our service team at Solargain to book a health check. Our experienced technicians will perform a full inspection of your system to determine whether the relay failure is permanent or not. If the faulty inverter needs replacing, we suggest either a Growatt, Zeverlution or Fronius Galvo 2 inverter. Please don’t hesitate to contact us to discuss your options.

DC INJ HIGH error

If your Orion inverter tells you it has a DC INJ High fault, it’s possible that DC voltage is travelling through your inverter outside of it’s tolerance limits. To prevent damage from occurring to it’s components your inverter will shut down. The best way to confirm whether this is what’s happening is to have an experienced solar technician come and inspect your system. Book a system health check with us to confirm the nature of the fault. In the case of an Orion inverter that is experiencing a DC INJ High fault, if we’re unable to repair it, it’s likely you’ll need to replace your inverter.

Is a DC INJ High fault covered by warranty or under my household insurance?

Unfortunately, this type of fault isn’t covered by insurance, and since your Orion inverter is likely to be more than 12 months old, it is no longer covered by warranty either. That said, if you need to replace your Orion inverter, we can recommend the most cost-effective replacement for your household and should be able to have it installed very quickly.

How do you resolve an Orion inverter DC INJ High fault?

Call us and book your system in for a health check. We’ll get to the root of the problem as soon as possible and fix it if it can be fixed. If your inverter needs replacing, we carry replacement stock with us whenever we go out for a site visit, so we can swap the faulty inverter over for a new unit. Suitable replacements for faulty Orion units include Growatt, Zeverlution and Fronius Galvo 2 inverters.

All Faults

See below for the full list of Orion faults and remedy instructions.

Fault Code Description Remedy
No Utility No AC line Verify that the solar supply main switch - which is located in the meter box - is on. If there is power to all three phases of your home, we suggest you book a system health check for our technicians to inspect the isolators. If those turn out to be functioning normally, they will need to look at the AC fuse as well (which will incur an additional $20 fee). If the isolators and the AC fuse are in working order, we will need to replace the inverter.
PV Over Voltage PV voltage is too high If the fault is intermittent, it indicates a peak in the system's production. If, on the contrary, it is constantly showing, including early in the morning and late in the afternoon, it is the sign of a permanent failure, so the inverter will need to be replaced. Contact us to book a solar maintenance service.
DC Bus High DC bus voltage is too high If the fault is intermittent, it indicates a peak in the system's production. If, on the contrary, it is constantly showing, including early in the morning and late in the afternoon, it is the sign of a permanent failure, so the inverter will need to be replaced. Contact us to book a solar maintenance service.
DC Bus Low DC bus voltage is too low If the fault is intermittent (for instance, if it is only showing in winter, in the early morning or late afternoon), it indicates a low DC output. If, on the contrary, it is constantly showing, including at peak production times, it is the sign of a permanent failure, so the inverter will need to be replaced. Contact us to book a solar maintenance service.
Over Temperature Temperature is too high An "Over temperature" fault means a fan has failed. This fault will usually appear intermittently at first, and ultimately become terminal. The inverter will require replacing. Contact us to book a solar maintenance service.
Grid Fault Grid voltage or grid frequency is wrong Verify that the AC isolator and the solar supply main switch - which is located in the meter box - are on. If the fault is intermittent, it indicates a grid voltage issue, which will need to be reported to your power distributor. If, on the contrary, it is constantly showing, the inverter requires replacing. Contact us to book a solar maintenance service.
Device Fault Hole sensor, GFCI device If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
Isolation Fault PV panel isolation problem Verify that the solar supply main switch - which is located in the meter box - is on. If it is, you will need to book a solar maintenance service for an electrician to check for water in the isolators. If the fault is intermittent (for instance, if it is only showing in case of moisture or rain), it means there is water infiltrating the installation. If, on the contrary, it is constantly showing, our technicians may have to check the AC fuse (at an extra cost of $20). It is possible your inverter will need to be replaced.
Impedance Fault Grid impedance fault If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
Ground I Fault Ground leakage too high This can be the result of water infiltration or an earth fault. We suggest you book a system health check to exclude any external cause before you replace the inverter.
Relay Failure Relay fail If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
DC INJ High Output DC injection too high If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
Ref 2.5V Fault 2.5 V reference voltage inside problem If the fault is intermittent, it could indicate the presence of moisture in the inverter board. If, on the contrary, it is constantly showing, the inverter requires replacing.
DC Sensor Fault Output DC sensor abnormal If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
GFCI Fault GFCI detection problem If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
Sci Fault Communication between master and slave problem If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
Consistent Fault The value of master and slave are mismatched If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
CPU Ver Mismatch Firmware version of master and slave are not the same If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
EEPROM Fault EEprom problem If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
Grid V Mismatch The Grid V of master and slave are mismatch If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.
Grid F Mismatch The Grid F of master and slave are mismatch If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service
Grid Z Mismatch The Grid impedance of master and slave are mismatch If this fault is permanent, the inverter needs to be replaced. Contact us to book a solar maintenance service.

Power light on BUT OP WATTS=0   This indicates a faulty system. The inverter needs to be replaced.
Completely dead No lights, no screen Verify that all switches are on. If they are, the inverter requires replacing.
DC Curr Mismatch The output DC current of master and slave are mismatch  

Orion was a Taiwanese-manufactured inverter imported by an Australian wholesale company called Solar Energy Australia (SEA) as early as 2008 and installed by Solargain up until 2011. As they carried a 3- to 5-year warranty, they would now all require replacing as their warranties would have long since run out. 

Replacement options for a 2.2 kW model - which is the most common type installed in Australia - include Growatt, Zeverlution and Fronius Galvo 2. Orion units being plug-and-play, labour costs are not covered by your warranty. If you would like to have a technician visit your home to uninstall the faulty unit and replace it with a new inverter, you will need to book a maintenance service which we will be happy to provide.

If your Orion inverter develops a fault and you are still under warranty, please contact our service team for help. We take all of the hard work out of the warranty claim process. Alternatively, you may want to consider our trade-in offer. Speak with one of our customer service representatives on 1300 73 93 55 for more information on this and other options.

What if I’m no longer covered by warranty?

If your Orion is now out of warranty, we recommend booking an inverter health check with us. One of our experienced technicians will inspect your inverter, identify any faults and, where possible, repair them on site that very day. If we cannot repair your inverter during that visit, we will bring a replacement inverter with us to save you multiple site charges. An entry-level 2kW unit starts at only $750.
