To check whether it is an actual inverter fault, you can safely perform your own free Inverter Health Check by carefully following these instructions:

IMPORTANT:  Carefully follow this procedure exactly to ensure your safety.

First step – switch everything off – AC and DC isolators, to reset the inverter.

1.  First, switch off the Solar AC Supply switch, which is clearly marked and usually located either beside the inverter itself or in a nearby switchboard or meter box.

2.  Next, switch off the Solar DC Supply switch, always located next to, under, or on the inverter itself.

3.  Wait for 60 seconds.  At this stage, all lights should be off, and the information screen should be blank.  

4. Leave everything switched off for at least two full minutes, and preferably for 5 minutes, before proceeding.   Remember, up to 600 volts DC can still be present inside the inverter for several minutes, even after it is switched off.


Second step, rebooting the inverter.

1. Get a notepad, and a pen, to take down a record of what happens.

2. First, switch on the Solar DC Supply next to the inverter, and record what happens.  (You may get some lights showing, or something on the digital display)

3.  Second, switch on the Solar AC Supply, and again record what happens, and what lights come on, flashing or still. 

4. If there is a display, it should start counting backwards at this point, or there may be a flashing light, for at least a full 60 seconds.

5.  At the end of at least 60 seconds, you should hear a slight noise, a click, and the inverter should start.

6. If the inverter does not start up, or there is an error message on the display, record exactly what it says, and let us know when you call.    We will also require the additional information mentioned above, including the Make, Model, and Serial Number of the inverter, and date of original installation, in order to best advise you on what to do next.   We do not charge for advice, even if you were not originally our customer.  We are genuinely pleased to be able to assist you.

Inverter  warranties

Some inverter manufacturers no longer exist, others charge overseas freight to honour their warranty, and yet others have a free change-over service.   Some may offer you to update your inverter to the latest model for improved performance, at a special reduced cost.   When we know the details of your inverter and the problem, we are happy to advise you further.

We can service most brands, including Aerosharp, Growatt, Kinglong KLNE, Solar King and SunnyRoo, in Melbourne, Brisbane and the Sunshine Coast.   Sometimes we need to send the inverter to technical specialists for assessment and repair.

From experience, we can report poor success rates in repairing Sunna, and Sunny Roo brand inverters, and would advise upgrading those models for reliability and better efficiency.  We have reliable budget and premium models to choose from.

Latronics inverters generally don’t need to be replaced, are always quickly repaired and updated by Latronics, at their Queensland factory.

We can arrange for collection, repair or replacement of your solar inverter in most areas, even if it was originally supplied by another company.

Our service is punctual, honest and reasonably priced, with the emphasis on repairing where it is economically worthwhile.

Causes of Inverter failure.

Solar inverters can fail due to many reasons, the most common we have encountered are –

  • lightning strikes
  • transients in the grid voltage
  • flash from the solar panel
  • internal components ageing
  • excessive heat
  • operating beyond the design voltage or current limits.

We have also found “natural causes” such as ants nests, wasps and geckos, to have caused failures.

Often, the cause is not obvious and only discovered when the unit is on the test bench, at the service department.

Kinglong Sunteams inverterWe have some used Kinglong (KLNE) inverters available for like-for-like change-over for $199 each.


An opportunity to Upgrade?

Failure of your old inverter may be a good opportunity to upgrade to a better, more reliable or higher efficiency inverter.

Especially if an insurance company, or the power distributor, has agreed to pay the replacement cost.  

Modern designs are generally more efficient, and more reliable than earlier types.  

We can supply high-quality Chinese, Australian and European-made alternatives.  

When you weigh up the benefits, including a new warranty, higher efficiency, better performance and increased safety, often it just makes sense to consider upgrading the inverter now.  New inverters will give you more usable power, and come with a manufacturer’s 5, 7 or 10-year warranty.
