Types of Solar Inverters

Solar inverters come in several different types, each with its own unique features, advantages, and drawbacks. The key is understanding how they all work and picking the one best suited to your needs. Fortunately, when you choose Vista Electrical Controls, you get the very best advice to help with this decision. So, let’s take a look at the different types of solar inverters you can choose from.

String Inverters

With a string inverter, all your solar panels are linked together in a series or ‘string’. Your solar panels produce DC electricity and send it to a single inverter, which converts it into usable AC electricity for your home.

The major advantage of string inverters is their simplicity and cost-effectiveness. They have fewer components, which usually means lower installation costs and easier maintenance. That can be paired with optimisers, and there are fewer parts to monitor.

However, the downside is that a single underperforming panel can drag down the output of the entire string. Suppose one panel is faulty or even obscured by shade. In that case, the entire string’s efficiency drops equal to the output of the weakest panel. As a result, they aren’t the best option for roofs that experience shading.

CALL NOW 1300 181 116

Microinverters

Instead of linking all the panels together in a string, a microinverter is attached to each solar panel. This means each panel’s DC electricity is converted into AC at the source rather than delivered through one solar inverter.

One of the main advantages of microinverters is the capacity for each solar panel to perform at its best. If one panel is shaded or not working correctly, it doesn’t affect the performance of the other panels. So, if you have a roof that gets shaded by other buildings or trees, microinverters should deliver a more optimised performance than a standard string inverter.

On the downside, microinverters are more expensive upfront because you need to buy several of them. They may also require more extensive wiring, adding to the installation time and cost.

CALL NOW 1300 181 116

Power Optimisers

Power optimisers are a hybrid between string inverters and microinverters. They are connected to each solar panel, similar to microinverters, but there’s also a central string inverter involved in the system.

They are most suited to people looking to balance efficiency and cost. Power optimisers still ensure each solar panel performs well on its own, but there is also a central inverter. Identifying issues and replacing faulty optimisers is cheaper and easier than replacing microinverters.

However, the installation process can still be complex and time-consuming.

Choosing the Right Solar Inverter for Your Needs

Choosing the right solar inverter is essential whether you’re installing a solar power system in a residential or commercial setting. Several factors should be considered, depending on the setting and the type of system you install.

Considerations for residential installations

For residential installations, the size and capacity of the solar inverter are major considerations. Solar inverters are rated to handle a certain capacity of electricity generation. So, if your solar panels generate more energy than your inverter can handle, the energy effectively goes to waste. On the flip side, purchasing an expensive inverter and only a few solar panels means your system won’t generate the amount of energy your inverter can handle. You may be potentially missing out on free solar energy.

The grid connection requirements, which may vary based on local regulations, are another essential factor. The team at Vista Electrical Controls understands local guidelines, so you don’t need to worry. But you will need to consider the orientation and placement of your solar panels to ensure maximum benefit.

Considerations for commercial installations

For commercial installations, scalability is the biggest factor. There are still the same considerations as a residential installation, but system design plays an enhanced role in a commercial setting. It’s often better to install a solar inverter with a higher capacity than you need initially. This way, if your energy consumption increases or your needs change, you can potentially add more solar panels without installing a new inverter.

Vista Electrical Controls works closely with commercial property owners to determine the type of system you need. This involves analysing historical energy usage patterns to design a system that handles your needs. Working with solar energy professionals is the best way to ensure you maximise your return on investment for commercial solar installations.

You’ll also want to consider the maintenance requirement for your commercial solar system. Durability and reliability are key in selecting solar inverters and panels because you don’t want endless repairs disrupting your energy supply. We can take care of any regular servicing and cleaning requirements, ensuring that your system keeps producing solar energy efficiently for years to come.

Installing and maintaining your solar inverter are key aspects of ensuring it performs efficiently over its lifetime. As we’ve already discussed, different maintenance requirements exist for different types of inverters. For example, if there is an issue with one solar panel in a string inverter setup, you’ll need the problem fixed quickly. With microinverters, the need for repair is still important but less urgent. Here’s what you need to consider.

CALL NOW 1300 181 116
Solar Perth installer working on solar inverters. Man in hard hat installing solar panels. Renewable energy solutions in Perth.

Proper installation begins with a thorough site assessment and preparation. This includes understanding the local climate, deciding on the best location for the inverter, and preparing the site for installation. The inverter must then be correctly mounted and wired according to the manufacturer’s instructions and local regulations. Finally, the system must be tested and commissioned to ensure it operates correctly and safely.

We take care of the installation at Vista Electrical Controls, so you don’t need to worry. Our experts determine the best location and orientation for solar panels to ensure maximum productivity. But we’ll also ensure your inverter is in a safe spot to continue working to its full capacity.

Once your solar inverter is up and running, it’s essential to maintain it well to maximise its lifespan and efficiency. This involves regular cleaning and inspection to prevent dust and dirt from accumulating and affecting the system’s performance. This applies to solar panels, too, although rain does much of the work for you to remove dust and grime. But you’ll also want to watch for bird droppings or other debris that may decrease performance. Usually, a gentle wipe-down with warm, soapy water twice a year is fine. Never use harmful chemicals or abrasive cleaning products on solar panels.

Regular monitoring and data analysis can help identify potential issues early on and ensure the system performs at its peak. Most quality inverters come with apps that allow you to identify performance issues as they occur. While there are some simple troubleshooting tasks you can perform yourself, it’s always best to contact us if you have concerns. Our solar experts can assess and repair any inverter problems you may encounter.

Maximising the Performance of Solar Inverters

You can take several steps to maximise the performance of your solar inverter and get the most out of your investment. This is important because a solar installation has an upfront cost. While the energy savings you gain effectively mean the system pays for itself over a number of years, you still want to ensure maximum productivity to keep your energy bills even lower. The more solar energy you produce, the more savings on your regular energy bill.

Optimising system design and layout

One of our first jobs when installing your new solar inverter is to assess the entire system design. As we touched on, this includes analysing your energy consumption and determining the right combination of solar panels and inverter. It’s a lot more complex than that, however, because we also need to consider the placement of your panels.

Our solar professionals consider whether your roof is subject to any shading, as this can affect solar energy production. We also aim to mount solar panels on the optimum angle and orientation to catch more sun for longer hours of the day. Of course, we also ensure all wiring and circuits are installed safely and correctly to optimise performance.

Monitoring and optimising energy production

Regular monitoring and data analysis can help you keep track of your solar inverter’s performance and identify any potential issues early. Solar monitoring systems can provide real-time data on your system’s output, helping you maximise your energy production. Most solar inverters include this functionality today, and some even connect to smart apps that allow you to monitor performance from anywhere.

This valuable data also gives you an insight into how you use power throughout the day. Knowing when your solar system produces the most energy lets you maximise how you use appliances such as dishwashers and washing machines to save even more money on electricity bills. Plus, identifying performance issues early means they can be resolved with hardly any disruption to your power generation.

Frequently Asked Questions (FAQs)

Choosing the best solar inverter for a residential setup depends on specific factors. However, microinverters are often ideal as they optimise each panel’s output independently. This flexibility benefits homes with complex roof designs or shading issues, thus maximising the system’s overall performance. Ultimately, every home is different, and we can suggest various options to suit your budget and requirements

Solar inverters typically last 10 to 25 years, although high-quality models are usually at the higher end of this range. Lifespan depends on quality, installation, maintenance, and environmental conditions. Regular inspections and maintenance can help your inverter last longer, so we suggest booking in for regular solar system inspection and cleaning to address any issues quickly.

You need a qualified, approved and licensed technician to install your solar inverter. All solar installations involve wiring and electrical work that professionals must undertake. Also, only a licensed contractor can connect your system to the main electricity grid. Plus, attempting the installation yourself can compromise your insurance coverage if something goes wrong.

To maximise your solar inverter’s performance, ensure proper installation and regular maintenance. This includes cleaning, inspections, and using monitoring systems to track performance. In addition, a lot of the work done to maximise solar performance is handled at the installation stage. With careful system design and planning, we ensure your Perth solar inverter performs as it should.

Yes, several incentives and rebates can help offset the cost of solar inverters in Perth. These include the federal government’s Small-scale Renewable Energy Scheme, which helps reduce the upfront cost of purchasing your solar panels and solar inverter. If you’re unsure about federal or state solar incentives, all you need to do is ask our friendly team, and we’ll be happy to help.
