Have you been scouring the web for help with your Sofar inverter problems? First, a sigh of relief: because you’ve come to the right place.
Sofar inverters are great at converting the solar energy that your panels produce into usable electricity. But like any piece of advanced technology, issues may arise over time. The good news is that many of these solar inverter problems can be solved without the need for professional intervention.
In this exclusive guide, we’ll walk you through the Sofar inverter troubleshooting steps that will help you diagnose and – hopefully!- fix your Sofar inverter right here and right now.
What is Sofar?
But first, a little about Sofar Solar. Originating in China in 2012, Sofar has become a true global leader in efficient and affordable solar energy solutions. The company has expanded its reach into our great country of Australia, and particularly in Queensland, where solar power adoption is at an all-time high. Sofar’s inverters, such as the Sofar 4.4KTL-X, are highly regarded for their efficiency, reliability, and advanced technology.

However, even the best global technology can experience issues – which is exactly where this troubleshooting guide comes in!:
Common Sofar inverter problems & 7 easy troubleshooting steps
If your Sofar inverter isn’t working as expected, follow these easy steps to resolve the issue:
1. Check for power supply issues
First things first: Is your inverter receiving power?
Your inverter relies on both solar panels and the grid for power, so check that both are functioning properly:
Inspect the AC and DC switches to make sure they are in the “ON” position.
2. Inspect the display for error codes
The helpful Sofar inverter error codes displayed on the screen are clear indicators of a problem. You’ll need to refer to the user manual to interpret these codes accurately, but these are the most common:
Error Code 101 – Grid Overvoltage, meaning the grid voltage is too high. Check the voltage settings, and if it persists, consult a professional
Error Code 102 – Grid Undervoltage, that means the grid voltage is too low. Check that your home’s electrical system is functioning correctly.
3. Reset your inverter
Sometimes, all you need is a simple reset to resolve an issue.
Power down the inverter by turning off both the AC and DC switches
Wait for a few minutes, then turn them back on.
Hopefully, this has resolved the issue – and this step can resolve many more Sofar inverter fault codes to restore full functionality.
4. Check the solar panel input
Inspect the wiring from your solar panels to the inverter, because loose or damaged cables can disrupt the DC input, which the inverter needs to function.
Make sure all connections are secure
Also check for visible damage to the cables or connectors.
5. Monitor the temperature
Sofar inverters are designed to work efficiently, but overheating is still a common problem.
Ensure the inverter is in a well-ventilated area
Are you sure it’s still exposed to direct sunlight?
High internal temperatures can lead to Sofar inverter problems and cause the system to shut down temporarily. If overheating is a regular issue, ask a professional about installing a fan, or relocating the inverter to a cooler spot.
6. Software & firmware updates
In some cases, something as simple as outdated firmware can cause performance issues or trigger false error codes.
Check Sofar’s website for any available updates for your model
Follow the instructions to install the latest firmware.
This can resolve potential software-related problems right there.
7. Inspect for ground faults
A ground fault occurs when electricity takes an unintended path, often due to poor insulation.
Ensure your wiring is intact
Is it possible that moisture has entered the system?
If you suspect a ground fault, consult with an electrician – as this can be an extremely dangerous issue!
When to call a professional
While many Sofar inverter problems can be fixed with simple troubleshooting like the above, some issues definitely require professional assistance.
These include:
Persistent grid voltage errors that are not resolved after resetting the system
Inverter internal component faults, which may require part replacements
Ground faults or insulation issues that cannot be safely inspected without proper training.
For any of these more complex issues, it’s definitely best to get in touch with experienced and fully-licensed solar technicians in Brisbane.

You undoubtedly already know this, but solar power is a fantastic investment for both your wallet and the environment. Not only do solar panels provide clean, renewable energy, they also offer long-term savings on electricity bills that for everybody else are absolutely skyrocketing. The even better news is that modern solar panels are designed to be incredibly durable, often lasting 25 years or more with minimal maintenance.
But as we begin to emerge from another wet and wild winter, it’s a good time to address a common concern: can hail damage solar panels?
Understanding solar panels and hail damage
Did you know that most parts of Australia experience 1-3 ‘hail days’ per year? And that in more storm-prone areas, including Queensland, that number can rise to as many as 5-10 annual hail days? Now, while the panels on your roof are designed to deal with extreme weather, including strong winds and heavy rain, huge chunks of ice falling at high speed can be a different story.
1. Can hail damage solar panels?
The answer is simple: Yes.
But the good news here is that hail damage is still quite rare. That’s because your solar panel engineers designed these products to cope with all sorts of weather – including normal hail. And the best solar panel brands out there were every tested to withstand hailstones up to about 3cm in size, falling at terminal velocity.
Beyond that, though, your panels could certainly sustain some hail damage.
2. Solar panel hail damage: What to look for
After a hailstorm, it’s a good idea to check your panels out for visible damage. You’ll be looking for:
Cracks
Chips
Any signs of impact.
Remember, even minor damage can affect the efficiency of the panels over time, so those hail stones might have damaged something internally that you cannot see. Monitor your system’s output over time to check for inconsistencies that might suggest damage.
3. Are solar panels hail proof?
While no solar panel is ‘hail proof’, some have a higher hail rating than others. Check out the technical specifications provided by your manufacturer, as well as:
IEC 61215 certification, including testing for mechanical loads
Third-party, independent hail testing your manufacturer may have commissioned
Warranty and durability statements
Customer reviews
The use of tempered (impact resistant) glass.
4. Hail damaged solar panels: What to do next
If you’re pretty sure your panels have sustained hail damage, head to your inverter and see if you also notice a performance decline or error messages.
5. Insurance for solar panel hail damage
It’s possible your insurance policy covers hail damage to solar panels, so check out the details specific to your policy.
6. Preventative measures against hail damage
Ok, so you can’t control the weather, but you can take steps to protect your solar panels from it. Look into protective covers or netting, and schedule regular professional solar maintenance and inspections too so that potential vulnerabilities can be addressed before they become serious issues.
7. Professional help & repairs
If you’ve discovered hail damage on your solar panels, check in with experienced and licensed professionals for solar repairs – so you protect your expensive investment and ensure not a single ray of energy-producing sun is missed!
Solar panels hail damage – What’s next?
Solar panels may be durable – but when those hail stones are as big as baseballs, already understanding the potential risks and having taken preventative measures is your best bet.

What we’ve done is summarise some of the major categories of Fronius inverter problems and break down their related error codes – and let you know what you should do next:
1. Grid connection issues
Error Code 102: Grid voltage out of tolerance, which indicates that the inverter is detecting voltage from the grid that is too high or too low.
WHAT’S NEXT?: Check if the grid parameters set on the inverter match the local grid’s requirements. If you have no idea, you’ll need expert support.
Error Code 301: No grid connection, telling you that the inverter is unable to detect a connection to the electrical grid.
WHAT’S NEXT?: If your home has power, get help for your inverter fault.
2. Communication problems
Error Code 401: There’s a communication error between inverter components, suggesting an issue with internal communication.
WHAT’S NEXT?: Try resetting the inverter, and checking all data communication connections. The next step is expert support.
Error Code 402: There’s a problem with the connection to external monitoring devices, or the internet connection for remote monitoring. Fronius 999 error is similar.
WHAT’S NEXT?: Check your internet connection and external monitoring system configuration. The next step could be checking the manual for setup advice – or pro help.
3. Over temperature
Error Code 117: Your inverter is overheating, which can be caused by hot weather or inadequate ventilation around the inverter.
WHAT’S NEXT?: Is your Fronius being blasted by direct sunlight? And is there plenty of room around the device for ventilation? Resolve the issues ASAP to protect the sensitive internal components.
4. Internal faults
Error Code 443: Depending on where you refer to in order to understand the 443 error, you may get different answers – like asymmetric voltage or DC energy transfer failures. The truth is that a general internal error has occurred inside the box, indicating a serious inverter malfunction.
WHAT’S NEXT?: This type of fault typically requires an inspection or repair.
Error Code 475: This internal fault has been triggered by a solar panel grounding problem, causing an internal relay failure.
WHAT’S NEXT?: Power down your Fronius inverter straight away and call for help.
5. Firmware issues
Error Code 609: This is the one we mentioned at the top – the “configuration value out of limits” problem that leaves you scratching your head. The most likely explanation is that the device’s firmware has become out of date and needs an urgent update.
WHAT’S NEXT?: You may be able to follow Fronius’ instructions to perform the update yourself, but expert guidance is recommended to ensure proper procedures are followed to ensure compatibility.
Extra mentions:
Fronius state 509 may simply be a polite request for a solar panel clean
Fronius state 307 may not be a major problem at all – perhaps there’s just not enough sun in the sky
Fronius error 105 and Fronius error 102 are AC power problems, but they should resolve themselves with no user intervention
The explanation to Fronius state 104 is hard to find on the internet, but it’s another grid issue that should resolve when the supplied power is back within tolerable limits
Fronius 999 error.
Fronius inverter problem? Here’s the quickest fix
The good news is that Fronius inverters are renowned for their detailed diagnostic systems – but the bad news is that all the way from 100 to 999, there are an awful lot of those Fronius error codes!
The easiest way to identify, troubleshoot and resolve the full spectrum of solar inverter problems so that your system is protected from total failure and always running optimally is with the help of Solar Repair Service.
Have you gone solar? You’ll never regret making this on-trend and transformative decision, as it not only represents a massive step towards a sustainable and ‘green’ lifestyle but will also drive down or slash your power bills just as they are soaring. But now that you’ve tapped into solar energy’s potential, considering solar battery storage is the logical step to take it to the next level. Integrating a solar battery in Brisbane allows you to store rather than waste excess solar energy you generate during the day – meaning you can enjoy continuous and reliable ‘free’ solar energy at night or when the grid goes down. But are you asking yourself: What size solar battery do I need?
What size solar battery do I need for my house?
They say that size doesn’t matter, but that’s definitely not true when it comes to solar battery size. Now, when discussing solar battery sizes, we’re not talking about its physical dimensions but its storage capacity and power output. Too big, and you’re only wasting money and even compromising solar power’s overall efficiency. And too small that you won’t be able to store enough solar power for your household’s needs, leaving you just about as reliant on the grid as you were in the first place.
Why a solar battery sizes chart isn’t enough?
Just planning to use one of those free online solar battery size calculator apps you’ve seen? While they may give you a decent idea to estimate your solar battery needs, they merely use generalised assumptions and standard formulas. And few of them factor in your specific consumption, the unique solar potential of your location, your daily usage fluctuations, and the efficiencies of different solar panel types.
Remember, a mismatch between the right solar battery sizes for you and the actual product you purchase takes away from the efficiency and cost-effectiveness of your solar setup. The solution?
Try our detailed guide to correct solar battery sizes
Try our exclusive and thorough step-by-step approach to helping you answer the question: What size solar battery do I need?
1. Check your daily energy usage
First, we’ll need to figure out how much your household is using energy every day – on average. Helpfully, you should find the figure in kilowatt-hours (kWh) on your power bill, but also pay close attention to identifying patterns and peak usage periods.
2. Assess your solar panel output
Now, we’ll need to figure out how much of that daily usage is already taken care of by your solar panel setup’s average daily energy output. And the answer doesn’t just depend on the panels, but also on where you are and the amount of sunlight they are exposed to at different times throughout the year.
3. Evaluate peak demand times
Observe that at certain times – let’s say evenings when everyone’s home – your household energy demand tends to peak. It’s therefore critical to not just have a basic capacity overview, but whether your solar battery is capable of meeting peak rather than overall energy demand – especially in non-sunshine periods.
4. Calculate battery capacity needs
With your consumption and output data, you’ll now need to estimate the required storage capacity of your battery – usually in kWh. This step means:
Breaking down usage over different times of the day
Subtracting consumed solar energy from total consumption
Factoring in days of low solar production (ie. the need for surplus energy)
Striking a balance between excess capacity & inefficiency.
5. Don’t forget about depth of discharge (DoD)
Once you calculate solar battery size roughly, don’t forget about the DoD – the concept that these batteries vary in terms of how thoroughly they can be depleted of energy. So once you hone in on a product, see how high or low the DoD factor is.
6. Don’t overlook battery quality
One of the differences between high-quality solar batteries and lower-quality ones is how much heat they lose during charging and discharging. Sometimes, a cheap solar battery may seem to have enough usable energy – and then you find that it’s pretty inefficient.
7. Is your solar panel going to work?
You can get a very good idea of solar battery capacity, only to discover that it’s not compatible with your existing solar system – or compliant with local rules.
Are you getting a good idea of what size battery you need for your house? If you thought our step-by-step process was straightforward, don’t forget that each step involves complex calculations and personalised considerations – and even more layers of data analysis and a deep understanding of solar energy systems.
Ask our experts about solar battery size

We live in an era marked by the ominous challenges of climate change and skyrocketing energy costs. But there’s good news: there’s never been a better time to make the big leap by transitioning your home to solar energy. Now, just about every homeowner understands that turning that free and abundant energy from the sun in the sky into clean and green usable electricity requires solar panels. But you may be surprised how often our Queensland solar electricians hear the questions: “What is a solar inverter?” and “how do inverters work”?
What is a solar inverter?
So let’s dive right in because without a solar inverter, those panels on your roof will still do all the hard work of capturing that delicious sunlight and turning it into electricity – but it will be useless for your household appliances and systems. Why’s that? Because the electricity those panels will make is direct current (DC) – and what our homes require is alternating current (AC). To keep it simple, the sun’s rays hit the photovoltaic cells and trigger a direct flow of electrons – DC power. It then needs to be fed into something that turns that simple DC power into electricity that can change direction (AC) – and for that, we need the solar panel inverter.
How do solar inverters work?
And what is a solar inverter? It looks like a compact, bow-like device, often mounted near your property’s main electrical panel, either indoors or outdoors. And how does an inverter work? Let’s keep it super-simple and as non-technical as humanly possible – and explain it step-by-step for you.
1. A ray of light
Imagine a ray of sunlight, travelling millions of kilometres from the sun to the solar panel on your roof. It hits the panel, the photovoltaic cell absorbs it, and it excites electrons – creating direct current (DC) electricity.
2. Conversion initiation
This DC electricity travels through wiring from the solar panel to wherever your solar inverter is located. Think of that inverter as a translator, taking the foreign DC language and converting it into the AC language that your household appliances speak.
3. The inverter’s inner workings
Inside the inverter, there’s a set of electronic components that work together including transformers, inductors and capacitors. They collaborate beautifully to change the characteristics of the electricity.
4. Pulse width modulation
One of the most critical processes occurring in the inverter is called Pulse Width Modulation (PWM). By using electronic switches, it turns the DC on and off rapidly, triggering a series of pulses. The length and spacing of these pulses almost perfectly mimics the wave-like pattern of AC electricity.
5. Creating the AC wave
These pulses are then smoothed out and refined by the inverter’s filters, resulting in a sine wave – the exact shape of standard, fully-useable AC electricity.
6. Final check & adjustment
Your inverter will then check the voltage and frequency of the power it’s converting to make sure it matches what’s going on in the electrical grid and your home – which is what your appliances and household systems require to work.
7. Powering your home
That DC power has become AC electricity, which is what your home needs. The newly-created AC power then flows into your home’s electrical panel – and is ready to be used by your TV, fridge, lights and anything else that would otherwise require mains grid power.

As Queensland rapidly transitions to clean, green and sustainable renewable energy, there’s one word that summarises the key to that success: incentives. After all, it’s incentives that turn a solar naysayer into an avid consumer of solar panels for their home, and encourage businesses to invest in solar technologies with financial, environmental and long-term benefits. For the consumer, one clear incentive that gets a lot of attention is our local solar feed in tariff QLD – but there’s another incentive that works hand-in-hand.
For many people, while the QLD solar feed in tariff and the installation of solar batteries are two such incentives, it’s always surprising to learn that not too many Queenslanders understand that they have a symbiotic relationship.
Feed in tariff QLD – What is it?
The simplest explanation is that the QLD feed in tariff allows solar-equipped homes producing excess solar energy to ‘feed’ it back into the grid for a financial benefit. In fact, if you get it right, the feed-in tariff can provide a steady extra income stream for solar panel owners, meaning it doesn’t just make those power bills smaller, but eliminates them entirely – and then turns solar power into a profitable venture!
For the number boffins, here’s the breakdown about the solar feed in tariff QLD:
It’s a standard rate of just over 10c per kilowatt-hour
With an additional time-varying rate of over 16c per kWh for eligible systems during peak periods.
How does it work hand-in-hand with solar batteries?
Separately, most solar power users these days understand very well that another key incentive is the increasing availability of solar battery installation. Basically, what it means is that you never waste a drop of that free solar energy because rather than losing it you can store it for when the sun isn’t shining. That way, even in the dead of night, you can be using free solar energy rather than paying for regular electricity from the grid.
The ultimate solar super-incentive
But how do the feed-in tariff and solar battery installation work hand-in-glove to create a true super-incentive? It’s all about unlocking solar synergies and amplifying the rewards. Let’s explain.
1. Maximised self-consumption
Slash and eliminate your reliance on grid electricity by storing excess energy for later use, increasing self-consumption to the max.
2. Increased financial returns
By combining the feed-in tariff with solar batteries, homeowners can not only earn income by exporting surplus energy to the grid but also further optimise their financial returns by using stored energy during peak tariff periods.
3. Energy independence
With solar batteries, you ramp up your energy independence by relying less on the grid and harnessing safely stored solar energy to meet power needs even during outages or at night.
4. Enhanced grid stability
Solar batteries contribute to the stability of the power grid we all rely upon by reducing the intermittency of solar energy generation and balancing electricity supply with demand.
5. Reduced carbon footprint
Combining the feed-in tariff with solar batteries promotes renewable energy adoption, slashing your carbon footprint even more extremely by minimising reliance on fossil fuel-based electricity.
6. Long-term cost savings
Just imagine making money, rather than spending money, on your energy needs! That’s a long-term saving on power bills, making solar power a powerfully attractive option from a purely financial point of view.
7. Sustainable energy transition
When you find synergies in solar incentives, we collectively accelerate the transition to a sustainable energy future, driving increased solar power adoption and powering the global effort against climate change.

Are you getting slammed with enormous power bill hikes at present? You’re definitely not alone – because industry experts admitted at the recent Energy & Climate Summit that your electricity will cost about 35% more this year compared to 2022. The good news, however, is that simply by switching to solar power, you can expect your bills to then drop by somewhere in the range of 50-70% on average – although some get that bill all the way to $0 or even start to actually make money with their solar thanks to a feed-in tariff. So if all that’s true, which it is, then why is my electric bill so high with solar panels?
Huge electricity bill with solar panels?
So you installed that solar system because you wanted to embrace sustainable energy and slash those electricity bills, right? If you’re perplexed about what’s gone wrong, it could be:
1. Wrong solar system size
If the capacity of your solar system is overwhelmed by your household’s energy consumption needs, not enough ‘free’ energy will be produced – and so your appliances will have to revert to normal, expensive grid electricity. And if this grid electricity is being used in peak usage times, it will cost even more.
2. Altered lifestyle
When a household makes the solar switch, one common phenomenon is that – knowingly or not – the people who live there suddenly start to use more electricity than ever because of the perception the electric bill after solar panels is so low. But just because the energy is free doesn’t mean it’s limitless – and once it has all run out, you’re back to grid electricity on top of those more power-hungry new habits.
3. Solar system faults
Has your power bill surge coincided with an error message or warning light on the inverter? What about the panels – do they look degraded, scratched or dirty? Have you had the wiring checked for faults that could have led to energy transfer inefficiency? Could connections be loose, cables damaged, or junction boxes faulty? If it’s been a while since you had some professional solar maintenance or at least a solar inspection done, get on it now.
4. Shading & orientation
Even if your solar system is technically functioning perfectly, changes in the way the panels get their sunlight – some new shade, or an outdated panel orientation – can cause quite dramatically lower performance. Even the tilt angle of your panels could just need a tweak, which is something an experienced solar electrician knows all about.
5. Seasonal/weather/climate variations
It won’t be a surprise to learn that your panels do a lot better generating plenty of free energy in the sunny summer compared to a particularly grim winter season. But even several unseasonable cloudy days can make a big difference too, not only in terms of what your system is capable of producing but also regarding your expectations for what a particular power bill will say at the end of the billing period.
