This repair guide for Aero Sharp solar energy system inverters aims to assist troubleshooting. It’s not intended to be a comprehensive user guide.

Aero-Sharp provides transformer-based inverters which can provide an output of 1kW, 1.5kW, 2kW, as well as 3kW. Their units usually come with a five-year warranty, with some units even bearing a promotional ten-year warranty. However, since the manufacturer is now out of business, it is highly unlikely that the additional five years in the ten-year warranty will still be honoured.

Common Faults with Aero-Sharp Inverters

Grid Volt Error

Your Aero-Sharp inverter is designed to shut down if the grid voltage surpasses 260V. When this occurs, your inverter will display a grid volt error in its screen and it will no longer generate any output power. To address this issue, your inverter needs to be reprogrammed to accept a higher voltage from the grid.

When your main control board malfunctions, a grid volt error can also occur in your inverter. In case your AC fuse blows up, or your AC board is encountering issues, your inverter may likewise display a grid volt error. If after having your AC fuse replaced and it immediately blows up again, then this is a sign that there is a short circuit in your AC board. In this case, your inverter needs a replacement.

Fuse Failures. The fuse failures of an Aero-Sharp inverter can be because of the use of an under-rated fast-blow fuse. In this case, replacing this type with a slow-blow fuse type can resolve a fuse failure issue.

Ground Fault

A ground fault can occur when there is an issue with how your unit is grounded. Fortunately, this is one of the issues that can readily be repaired by licensed electricians. However, if after a careful assessment and it is ruled out that the earth fault occurs internally in the inverter, then your unit needs to be replaced.

System Error

A system error is one of the common faults of Aero-Sharp inverters that can no longer be repaired. In this case, the best thing to do is to have a new inverter installed to replace your old one.

PV Overpower Error

In case you have installed a string of panels that either border or slightly exceed the maximum PV input voltage or current specification of your unit, then there is a great chance that you may encounter the PV overpower error. Generally, pushing the limit of your inverter should not be a significant problem, except when the sun emerges from the clouds, causing a huge increase in your inverter’s input that is beyond its specifications. More often than not, your inverter will respond by shutting down and attempting to start up again after a while.

High-pitched Noise

The earlier models of Aero-Sharp inverters were quite noisy, producing a high-pitched screeching noise. The noise becomes louder as the inverter produces more output power, such that at full load, or during midday, the noise can be painful to the ear. Fortunately, the newer Aero-Sharp inverter models are designed to be quieter. In addition to this, the 50Hz transformer hum is only audible when you stand closer than a meter away from it.

Battery Fault

There are instances wherein your inverter may experience a battery fault or issues with the three-volt CR2032 lithium coin cell that powers the display panel mounted behind the front lid. Without this battery, your inverter’s clock, as well as its previous history, recording your inverter’s total time of operation and accumulated output, may be lost. Additionally, a faulty battery may cause the internal clock of your inverter to reset or your inverter may not record its daily kilo-watt hour output properly. Fortunately, this battery is replaceable.

In case your inverter is still within its warranty period, we can assist you with your warranty claim. Otherwise, we can be of service to help you get it back in its best condition.

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.
