Solax Solar Inverters- Independent Review

SolaX Power BannerOverview of Solax – Company History

SolaX Power commenced operations in 2010, headquartered in Hangzhou, China. Solax quickly expanded globally, entering the Australian market in 2014 when they opened an office in Victoria. Solax has 6 global offices and over 500 employees, distributing to 66 countries via 200 distribution channels. This has resulted in over 600 thousand Solax inverters being installed worldwide.

Solax is actively pursuing research and development through its affiliation with Zhejiang University. The university is one of China’s leading research facilities and the only national silicon material laboratory.

A Brief Rundown on Solar Inverters

A solar system’s inverter is the point at which the DC electricity produced by solar panels is turned into grid-compatible AC electricity.

String inverters have traditionally been the standard in the solar industry. They send the power produced by solar panels to a central inverter that changes it from the DC electricity to the usable AC electricity that powers homes.

Hybrid Inverters have the same characteristics as a string inverter with the additional feature of a charge controller, this is used to manage a battery system. Charge controllers can also be bought as an additional unit, but hybrid inverters provide the option of an all in one device.

Solax Inverter Efficiency

An important aspect of getting the most value out of a solar inverter is to choose an appropriately sized inverter to optimise the solar panel system efficiency. To read about the importance of inverter sizing and system efficiency click here.

Residential inverter efficiency standards are generally 95 to 98 percent, Solax Inverters either fall into or exceed this standard. The Solax residential inverter range has efficiencies from 97.1% to 98.5%.

Solax Inverter Warranty

In Australia, all CEC approved Solax inverters come with a 5 year warranty for parts and labour from the date of installation. An additional 15 year extension to the warranty can be purchased.

The standard 5 year warranty is rapidly becoming one of the shortest inverter warranties offered in Australia with many of the growing Chinese companies starting to offer a standard 10-year warranty. As we’ve discussed previously, a warranty is only worth something if the company providing it is still around and there is an accessible route to claiming it if your Solar Installer is no longer around.

Solax Inverter Costs

Solax Inverters are manufactured in China, this means that they will generally be cheaper than European manufactured competitors.

Indicative pricing

SolaX Inverter Model Indicative Price Range
SolaX Power X1-Boost 5.0 kW $700 to $1,000
SolaX Power X1-Smart 6.0 kW $1,300 to $1,500
SolaX Power X1-Smart 8.0 kW $1,500 to $1,700

Keep in mind that inverter costs generally only run between 10-20% of your total system, so often it is worth investing in a high-quality inverter given this will have a large impact on the efficiency and performance of your Solar Power project.

5kW system

Stopped working in April. While it had apparently ran out of warranty (5 years from manufacture date) they have chosen to replace it and cover some of the electricians costs.
