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


PROsine models deliver a sine wave output that is very much similar to the AC power supplied by a grid. They are primarily designed for recreational and industrial applications, capable of providing 1000 and 1800 watts of sine wave AC power with a 12V or a 24V input voltage. Thus, this model is best suited for electrical systems with a quality multistage battery charger.


PROwatt models are compact and relatively easy-to-use. They are also easy to install, which makes them ideal for commercial trucks, RVs, as well as marine applications. The great thing about this model is that it offers several safety features that are not commonly found in other inverter types.

PRO series inverters

PRO series inverters are intended for RV and marine electrical systems with a battery or generator already installed. Aside from efficiently providing household power whenever necessary, this model also features a detachable and digital remote control, complete with a display that shows vital information about its operation. The good news is that this model can also be easily installed to fit any compartment, mounted either vertically or horizontally.

XPower 450

The XPower 450 only needs to be plugged into the 12V lighter socket in your vehicle or connected directly into its battery and you will already have ample power to run your basic electronic appliances. Rest assured that you won’t have to worry about a depleted battery because this inverter can automatically sense low battery voltage. This inverter model is also designed with corrosion resistance and short-circuit protection, making it ideal for damp and humid environments.

XPower inverters

XPower inverters feature a high surge capability, which makes them ideal for those who have a need to support multiple loads. This model can easily be installed and operated, allowing you to have a supply of reliable power to run your home appliances. It also has an easy-to-read digital display that enables you to garner important system information immediately.

Freedom X True Sine

The Freedom X True Sine inverter model is designed to be lightweight and compact. It also has an extended surge rating, making it ideal for starting difficult loads such as a refrigerator. Additionally, you will be able to easily install this inverter because of its quick-connect terminals.

Troubleshooting tips for installing Xantrex inverters

Start with default settings

To ensure that your installation is a success, make sure that you revert all the settings of your inverter to factory defaults.

These are the values that will allow your inverter to work in a multitude of environments.
From there you can readjust your settings to suit your specific needs.

Just keep in mind to check each of the settings one at a time to identify an installation problem as it occurs.

Disconnect loads

Another troubleshooting tip that may help when installing your Xantrex inverter is to disconnect all loads.

After they are all disconnected, connect each load one by one. As you do keep an eye on the DC voltage. Make sure it is within the range of the inverter. This will allow you to isolate whether an ineffective circuit from the battery or your source voltage is causing the problem.

Stay safe

When troubleshooting your inverter, prioritise your safety by powering down as much as possible when you are working with circuits.

In case you are not confident with troubleshooting your inverter, it is best to call in the experts.

Standard workshop repair costs range from $195 to $495 – Please note there may be additional site visit fees applicable.

We provide a full range of solar inverter replacement options if repairs are not possible.

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.
