Solax Inverters

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) that are compatible with three different battery systems, including the LG Chem RESU 6.4.

Solax Single Phase Inverters

Solax single phase inverters are standard solar inverters that are sometimes called grid-tie inverters or non-islanding inverters, but usually, they’re just called 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. According to Tesla, the new 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 SL-TL1500 to SL-TL3000 Single MPPT Inverters

These inverters are available with capacities of 1.5, 2, 2.6, and 3 kilowatts. They only have a single Multiple Power Point Tracker (MPPT) which means that all the solar panels must normally face in the same direction to prevent losses, unless smart panels or some other form of optimization is used.

These inverters come with a warranty of 5 years.

The noise emission of these inverters is given as under 30 decibels, which is pretty quiet, but is likely to be more than twice as loud as a the more common noise emission by modern transformers of under 25 decibels. This is an important consideration if you are ever planning on installing one inside a sound studio.

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 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. 

As of the 2nd of June 2017 there are three battery systems Solax lists on their website as being compatible with these inverters. They are the Solax battery, LG Chem RESU, and the Pylontech Extra 2000.  Air Carbon Batteries were listed as being compatible in the past.

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.

Warranty Note

The warranty they provided for download for Australian on their website in November 2016 was not the Australian warranty but the UK one.  Currently in June 2017 I can't find any warranty for download on their site. So be sure to get your hands on an up to date Australian warranty before you buy.

SolaX Energy Storage - The SolaXbox

Solax produces an energy storage system called the Solaxbox that has a warranty of 5 years.

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.

About the only thing I would criticise with the Model Inverter we had installed is that you cannot get the information regards what has been fed back into the Electricity Grid and hence the amount of $ you are earning from your Electricity Supplier. So you have to trust what the Electricity Supplier tells you that you have received from the excess Power that has been returned to the grid from our system. However this is minor in my opinion to using the Solar Power during the day to cover Electricity usage by house appliances etc during the day. May in the future investigate Battery to store and use their power day and night which will need an inverter upgrade and will cover the above grid feedback monitoring by the inverter then.

This inverter has a small LCD display and some menu functions that enable the user to view various things, including KwH generated today, yesterday, and per month. It also retains 'errors' the system encounters along the way. We found that sometimes if there were interruptions to the standard electrical power for some reason, the system throws up an error code; and there were a few error codes that we could not identify.

The inverter has been pro forming very well with no problems. The web portal is well set up is a great monitoring system. It keeps the batteries charged as well as regulate the power usage in the house using the grid power as last resort. The service and support from True North has been really good. Great group of people to deal with.

Changed the score for the installation as the Eurosolar installers damaged the roof capping on our colourbond roof. This wasn't immediately visible until or apparent until we started using our A/C at the start of summer. I then noticed a 5cm bend in colourbond attached to ridge capping sheet near the roof A/C unit. Not happy and actually paid for a tradesmen to fix it out of my own pocket.

Never set up the wi-fi/cloud reporting capability. Initially some minor communication difficulties, which I am sure could have been resolved, but I was never that concerned about getting the feedback, hence never completed the setup. I know from casual observation of the output during what should be ideal solar conditions, that the inverter is producing the expected full power output. So I have never had any reason to doubt it's operation or efficiency.

From a consumer perspective it is very difficult to get the data to determine how efficiently your inverter is operating. If it doesn't fail, and you are getting around 70% of the nominal KW rating of the system purchased generated then you are probably achieving reality.

Monitoring software is a bit uninspiring. The installers Citisolar offered a 10 year warranty at the time of sale along with the assurance that the inverter was battery ready. After the installation it took me months of following up to get the 10 year warranty and the battery ready was acknowledged to be rubbish - we would not need it. Two months later Teslar announced their house batteries. Poor form Citisolar.

I had the hybrid system installed September 2017 since then I have tried to contact the company on 1300476529 many times to get the message all lines busy phone head quarters 0452631816. When I phone that number I find they are unavailable and asked to leave a message which is never answered. Since September I have been trying to configure my inverter to suit my needs eg. want to fix it feeds in at the expense of household use and battery and later on I am drawing more from grid than I should. This is a Chinese company that does not know customer service. I am very disappointed.

It has been installed for about five months now and no problems so far. I haven't connected it to the phone but will when I have holidays. Our first bill after having the solar installed for two months was $1600. Since then we have tried to only use appliances in the daytime.

Efficiency has dropped approximately 10% since I purchased it 12 months ago. Maximum generation is now approximately 4.7 kW though I think it's likely due to the panels rather than the inverter.
