Is your Latronics inverter faulty? Is the 75% light flashing and are the remaining lights off?

What does it mean if the 75% light is flashing?

If your Latronics inverter is displaying a 75% error, it may be having trouble connecting to the grid. Remember: if the 50% light is on solid while the 75% light is flashing, this is not a fault. It just means your inverter is on the cusp of 75% production.

If the 75% light flashes continuously, it’s worth checking that the solar supply switch in your main switch board is turned on. Secondarily, the isolating switches mounted at your inverter should also be confirmed as “on”. If neither of these issues are to blame, please contact us on 1300 73 93 55 to further diagnose the fault.


Is my inverter covered under warranty or by my home insurance policy if it has a ‘grid check’ fault?

Most Latronics inverters installed in Australia came with a 3-year warranty; however, some came with a 5-year warranty. Refurbished units originally came with a 12-month warranty. Since Latronics inverters were only installed between 2009 and 2011, they are now out of warranty.

Depending on your home and contents insurance, you may be able to make a claim for your faulty inverter. Please contact us on 1300 73 93 55 so we can help provide details for your insurance claim.


How is a ‘grid check’ fault resolved?

Your Latronics inverter is probably either a 1.2kW or 2.5kW model. If you have a 1.2kW model, it’s likely you’ll be on a high feed-in tariff. Therefore, you’ll need to swap your faulty inverter for another 1.2kW Latronics inverter (new or refurbished), in order to retain your feed-in tariff as contracted.

A faulty 2.5kW Latronics inverter can be replaced with a 2.5kW Fronius Galvo inverter; however, the two units are wired differently. This would mean an additional labour cost of $1000 to bring the new unit up to standard, making it often more efficient to replace the entire system. This would mean new panels, and a new inverter at a similar cost to just replacing the inverter. You may also choose to take advantage of the opportunity to upgrade the size of your system, as prices of solar systems have come down over time.
