• Energy bill higher than usual?

• Installer gone broke?

• Out of manufacturer’s warranty by just a few months?

If your 1.5kw Inspire solar inverter has ceased working with no display on the screen and no buttons lit, then there could be an internal fault with your inverter or an external fault with your panels.

Trouble Shooting Tips

Below are some suggested solutions to your 1.5kw Inspire Non-Working Solar Inverter problem:

1. Have a licensed electrician perform a full diagnostic test and inspection.
2. If diagnostics test and inspection don’t reveal any problems and solutions, have a licensed electrician remove the faulty inverter.
3. The inverter will need to be sent to a solar inverter engineer.
4. The solar inverter engineer will repair your inverter and send it back to you.
5. Have a licensed electrician install the newly repaired inverter.

Please note that these are general tips only and are based on our current and past experience and therefore, not specific to your solar inverter problem.

• 50% of the time it’s a quick easy fix for any solar tech…

• Error messages and fault codes that are due to an external fault elsewhere in the solar system.
• The solar system is tricking the inverter into thinking it has that error or fault.
• External faults are relatively easy to find and repair. Once fault is repaired, the inverter is back online.

• Other 50% of the time

• There is a fault, which requires more diagnostic type of testing to locate the fault. Out of these about 1 in 4 can be solved onsite. Things like a dodgy install or water damage somewhere.
• The rest of the time it’s the inverter that’s the problem. 1 out of every 2 times the inverter can be sent away for repairs or we can organise those repairs under warranty with the manufacturer, and…
• The rest of the time the inverter was of low quality and either not fixable of not good value to fix. If this is the case we would quote on an inverter with similar specs to replace it with. Getting your system back online fast with high quality parts.
• In the worst case scenario, rare ground leakage faults are very difficult to find and fix but we have also had experience locating these aswell.

Client Case Study – Inspire 1.5kW Solar Inverter

Michael From Milperra

Michael called ACE as he was concerned about his solar inverter not working. There was no display on the inverter screen and Michael’s electricity bill had spiked within the last month.

On our initial diagnostics, there was 0 volts at the DC isolator. This indicates that there was a fault somewhere before the inverter and potentially within one of the panels. We inspected the panels and found a burnt cable on the DC isolator caused by a loose connection when first installed.

This issue was fixed by replacing the whole DC isolator on the roof with a new switch style isolator. This allowed us to carry out our diagnostics tests and determine where there was low voltage. After the tests were carried out, the inverter was unable to start up again. This resulted in shipping the inverter off to the solar engineer so they could carry out further tests.
