SolaX Power - Inverter Reviews

About SolaX Power

SolaX Customer Service: 1300 476 529

SolaX Power is a Chinese manufacturer that produces:

• Single and 3 phase solar inverters
• Hybrid inverters
• Batteries

Their products are aimed towards the budget-conscious.

Most SolaX inverters have a warranty of 10 or 12 years. But if their hybrid inverters are used off-grid they must be professionally inspected annually or their warranty will only last a single year.

At SolarQuotes we listen to installers we trust about the reliability of products and the level of customer service companies provide. Based on the limited information we've received so far, we do not currently include SolaX inverters among the products we recommend.

In a 'Formal Letter' we recently received from China, Solax said 'SolaX Power has made significant advancements in product performance and safety.' They also said their product quality was improving as they now select 'higher-quality suppliers'. 

Then they threatened Finn with legal action. 

Australian Office

SolaX Power has an Australian office in Springvale, Melbourne. Thanks to Google Maps I know its exact location. But judging by their map of office locations, SolaX is a little fuzzy on where it, or any other location, really is.

SolaX Production

In 2022 SolaX opened a new factory and dramatically increased their potential production capacity. They say the new facility will let them to build up to 22 gigawatts (GW) of inverter capacity per year.

You can read about the new factory here or you can check out the phrases I extracted verbatim from the SolaX website:

The new SolaX factory occupies a total area of around 100,000 sqm (30,341 sqm now in operation).

...a production capacity of 30GW (8.76 million annual units) in Inverter (600% increase).

...the AGV robots that shuttle through the factory are particularly eye-catching and intelligent.

The world is handing together on a sustainable path.

The factory is located in Hangzhou, a city of 12 million located 160km southwest of Shanghai.

Company History

SolaX was established in 2012. I'm almost completely certain it's not true there's a capital "X" at the end of their name because the company was founded by pirates who wanted "X" to mark the spot. Specifically, the spot where the name ends.

In 2013 they developed their first hybrid inverter and in 2014 they began selling in Australia. They now have over 2,000 employees around the world but I'm guessing most of them work at their factory in Hangzhou.

SolaX says they ensure all their suppliers meet ethical business standards, including on human rights and labour. So slavery would be right out.

SolaX Single Phase Inverters

SolaX has four different series of single-phase inverters. One that stands out is their X-1 MINI, as the smallest version has just 0.6 kilowatts (KW) of capacity. So if you're looking for a very small string inverter, SolaX is an option.

3-Phase Inverters

SolaX 3-phase inverters range from a small 3kW all the way up to 150kW, which is a size suitable for a large commercial solar installation.

Hybrid Inverters

SolaX produces a range of single-phase and 3-phase hybrid inverters or, as they call them, energy inverters. These can be used with compatible batteries, such as ones made by SolaX

Their single-phase hybrid inverters range from 3kW to 6kW while the 3-phase ones start at 3kW and go up to 30kW.

Warranties

If you'd like to examine it, here's a link to the Australian SolaX warranty.

There are two SolaX inverters that only have 5-year warranties:

• SolaX X3-PRO-G2 inverters of 17-30kW capacity
• SolaX X3-FORTH commercial inverters of 80-150kW capacity

All their other solar inverters have either 10 or 12-year warranties.

SolaX hybrid inverters have 10-year warranties but, if they are used off-grid, the warranties require you to pay for a professional inspection every year. Unless you are planning to have your system annually inspected anyway, this makes them a poor choice for off-grid use.

The SolaX warranty says it covers labour. By my understanding of Australian Consumer Guarantees, that has to be covered anyway, but it's always good when they put it in the warranty because it means you're not likely to have to fight to get it.

But the warranty also says it won't cover lost generation when Australian Consumer Guarantees appear to say you can claim for that loss.

Making A Warranty Claim

If you have a problem with a SolaX inverter, your first step should be to contact the business that installed it. They took your money in return for a properly functioning product and they have an obligation to see that's what you received.

If your installer is no longer around, then you can contact SolaX directly:

• SolaX service hotline: 1300 476 529

They can also be emailed at this address:

• [email protected]

My Recommendation

SolaX products are priced relatively low, so you may want to try them for that reason. SolaX claim to be working hard to improve the product quality and local support, which I applaud. But I still wouldn't choose one for my house. 

If you do have a SolaX inverter and want to leave a review, we'll be glad to have the extra information.
