About SolaX Power, Solar Inverters

SolaX Power solar inverters review

SolaX Customer Service: 1300 476 529

Solax is a Chinese solar inverter manufacturer with an Australian office in Melbourne. They produce inverters with 5 year warranties at competitive prices and claim they have a mean-time before failure of over 100,000 hours. This appears to mean their average inverter can be expected to operate for over 11 years before failing, but these figures are generally not calculated using real life conditions.

In addition to standard inverters, Solax also makes multimode inverters (also known as hybrid inverters) for battery systems.

Solax Single Phase Inverters

Solax single phase inverters are standard solar inverters that are sometimes called grid-tie  or non-islanding inverters. They don’t support the use of battery storage or allow electricity from solar panels to be used when the grid is down.

Homes with these type of inverters can have battery storage installed, but it will need to operate independently from the inverter and either be connected with a DC converter such as the Goodwe GW2500-BP or a battery-inverter such as the Sunny Boy Storage. The Tesla Powerwall 2 has a battery-inverter that allows it to be used with any solar inverter.

While they are single phase inverters, they can be used by homes that have 3-phase power.

Solax 3 Phase Inverters

SolaX also produces 3 phase inverters, but as their smallest is 10 kilowatts they are unlikely to see much residential use.

SolaX X1-3.0T to X1-5.0T Dual MPPT Inverters

These inverters are available with capacities of 3, 3.3, 3.68, 4.2. and 4.6 kilowatts. They have two Maximum Power Point Trackers (MPPT), which means they can accept two sets of panels facing in different directions. For example, a house could have panels facing both east and west if desired.

They come with a warranty of 5 years, but the datasheet points out this can be extended to 10.

Note that the X1-5.0T is not accurately named as it is only a 4.6 kilowatt inverter and not 5 kilowatts as its name suggests. 

The noise emissions of these inverters are given as under 25 decibels, which literally makes them whisper quiet, as a whisper is about 25 decibels.

SolaX Multimode (Hybrid) Inverters

SolaX also produces multimode inverters, also known as hybrid inverters, which can be used with battery storage. Their single phase ones come in 3, 3.68, 4.6, and 4.999 kilowatt capacities.  In addition, they also produce 3 phase multimode inverters with capacities of 5, 6, 8, and 10 kilowatts. 

The 4.999 kilowatt capacity single phase inverter is useful for installation in the Ausgrid Distributed Network Service Provider area of eastern Sydney as their people with single phase power are limited to installing inverters of under 5 kilowatts and 4.999 kilowatts is under 5 kilowatts. 

These inverters are available with internal or external battery chargers which can charge and discharge batteries at up to 1.25, 2.5, or 5 kilowatts. Note that not all battery systems can be charged or discharged at 5 kilowatts.

Their multimode inverters can provide backup power during a blackout and SolaX says they are suitable for off-grid use. But when used in off-grid mode the amount of power they can supply from batteries appears to fall by about 20%, so this will need to be taken into account when deciding what size battery charger to use.

In off grid mode their 3 kilowatt multimode inverter appears able to deliver 1, 2, or 3 kilowatts depending upon the size of its charger while their 5 kilowatt multimode inverter appears able to deliver 1, 2, or 4 kilowatts.

Solax Inverter Warranty Notes

The latest Solax inverter warranty for Australian customers can be found here - note that this was current as at March 2019 - you should check the Solax web site for the latest Australian warranty details before making a purchase decision.

As mentioned,  Solax inverters come with a warranty of 5 years, bit it can be extended to 10.

If you have an issue with your Solax inverter, your first step should always be to contact the business that installed your system.

Regardless of if you've been told otherwise, if that business is still operating they are the ones liable for the repair/replacement of a faulty inverter, if it is still within its warranty period.

If your original installer has gone out of business or is no longer contactable, warranty claims must then be lodged, by you, through Solax.

SolaX advise that a customer who can no longer contact their original installer will first need to arrange, out of pocket, for a solar installer to inspect and verify that there’s an issue with their inverter (if you don’t know how to find a solar installer, you can call SolaX’s Australian office on their number listed above for a referral). Once the issue has been confirmed by the installer, you must then contact SolaX’s Australian office. SolaX will then reimburse the installer up to $150, and work with the installer to arrange replacement of the inverter under warranty.

SolaX Energy Storage

Solax produces several different solar batteries available in Australia - the Solax 3.3 and 6.5, and the Triple Power 4.5 and 6.3. Details of these can be found on our solar battery comparison page.

My Recommendation

While SolaX is generally not considered as reliable as SMA, Fronius, or ABB inverters, they do have a lower price point and their multimode inverters appear to be one of the lower cost methods of installing some types of batteries with backup or off-grid capability. If you like their combination of low price and features then you can take a gamble on them, but I would go in eyes open and not expect them to last as long on average as the previously mentioned inverters.

Good: The inverters appear to working well (only a few days in so far)

Bad : The inverter wifi instructions are non existent. Searching for them on the internet consistently Lead to incorrect information.
The solax customer service refers you to speak to the installer. The installer - despite fair effort -couldn’t find different answers to me and referred me back to them.
Before I reached them I found the answer.

I simply needed to know the address for the wifi admin set up.
It is not 5.8.8.8 as all the internet setup info would have you believe. It is 11.11.11.1.

Once this was established the instructions were helpful and the set up, were I to do it again, is not overly difficult.

Initial teething problems after 2 months meant the inverter had to be replaced as it shutdown periodically and had to be rebooted. No issues with Cool or Cozy replacing it on the second check of the issue.

The Solax Inverter has ran to my knowledge flawelessly for 3 years. It's underperforming now but I feel thats because of the inferior quality solar panels provided by EuroSolar.

Soon after installation I noticed that the Inverter was faulty and would intermittently stop charging the system's battery while also curtailing the solar output by over 1000W. The malfunction continued intermittently and I lost countless dollars in feed in tariffs and lost savings from the battery system.

I had a Solax X1-5.0-T-N(AU) system installed mid 2019, in January 2020 it broke down - the unit was under warranty but it has taken more than 6 weeks and I am still waiting for a replacement. Be careful.
