If you’re new to solar power, you may be wondering “what does an inverter do?” and is it important for a solar energy system? In this guide, we explore the benefits of inverter solar power, what the different types are (string inverters vs micro-inverters) and why they’re important so you can decide if it’s a viable option for you.
Inverter solar power refers to the technology used to convert the direct current (DC) electricity generated by solar panels into usable alternating current (AC) electricity for the home. In residential solar systems, solar energy inverters ensure compatibility with your existing electrical infrastructure to maximise energy efficiency.
Inverters are essential components of off-grid solar systems, as they convert the DC electricity into usable AC electricity for powering appliances and devices in locations without access to the utility grid. Unlike a grid inverter, off-grid inverters operate independently to meet the entire energy demand of the off-grid system. Reliable inverters for off-grid purposes need to have:
There are many benefits of using solar power inverters. They allow you to:
By efficiently converting solar energy into usable electricity, power inverter solar panel systems, also known as solar power inverters or inverter solar systems, enhance the effectiveness and versatility of solar power installations.
Inverters ensure that the power generated by solar panels can be used in the home. This conversion process from DC to AC electricity ensures that the power can be used safely for household appliances and fed into the electrical grid. By providing compatibility with standard household electronics and optimising energy conversion, an inverter for solar panels enhances overall system efficiency.
Consider the following factors when choosing the most efficient inverter:
To choose the most efficient inverter for a solar panel setup, consider:
Suitable for larger solar installations, string inverters are cost-effective and simple to install in series. However, they are susceptible to shading issues and have limited performance monitoring capabilities.
Microinverters are installed on each individual solar panel, offering better performance in shaded conditions, enhanced monitoring capabilities and flexibility for system expansion. However, they tend to be more expensive than string inverters and may require additional maintenance.
Power optimisers are installed at the solar panel level, similar to microinverters, but they optimise the DC power output before it reaches the inverter. They offer improved performance in shaded conditions, however, they typically require a central string inverter for DC to AC conversion.
So, let’s deep dive into the two main editions of inverters. Central inverters and microinverters are two main types of inverters used in solar installations. Here are the main differences in more detail.
Central inverters are large, centralised units that convert DC electricity from multiple solar panels connected in series into AC electricity. They’re typically installed outdoors or in utility rooms and are cost-effective and easy to install. Central inverters are suitable for larger solar installations where there is more space and minimal shading. The efficiency of central inverters can be affected by shading, as the performance of all panels is affected by the lowest-performing panel in the string.
Microinverters like Soly’s Enphase iQ8 are small, individual units installed on each solar panel. They convert DC electricity into AC at the panel level and are usually installed on the back of the panel or nearby. Microinverters are ideal for smaller installations or installations with shading issues, as each panel operates independently, maximising energy production. Microinverters can improve system efficiency by mitigating shading effects and optimising the performance of each panel independently. However, they tend to be more expensive than central inverters.
Overall, central inverters are suitable for larger installations with minimal shading, while microinverters are better suited for smaller installations or installations with shading issues. Microinverter manufacturers such as Enphase offer a range of microinverter products designed to improve system performance and reliability.
Central inverters offer scalability, making them well-suited for large-scale solar projects. They can handle high power outputs from numerous solar panels efficiently, allowing you to expand the system as needed. A string inverter performs best in environments with plenty of space for installation, minimal shading and consistent sunlight exposure. Their centralised design simplifies maintenance and monitoring, making them ideal for utility-scale solar installations where reliability and cost-effectiveness are key.
The right home inverter impacts the performance and efficiency of a solar power system. By choosing an efficient inverter that’s compatible with your solar panel system, you can maximise energy production, reduce losses and save more on your energy bills.
Ensure that the inverters for homes you’re considering are compatible with various solar panel brands. Mismatched systems can result in decreased energy production, efficiency losses and damage to components. By selecting a solar panel inverter designed to work seamlessly with specific solar panel brands, you can maximise energy output, minimise downtime and protect your investment.
Leading microinverter manufacturers include Enphase Energy (like those used at Soly), SolarEdge Technologies and APsystems. These companies have developed innovative microinverter solutions that optimise energy production, enhance system performance and improve monitoring capabilities. Their microinverters allow for greater flexibility in system design, reduce the issues of shading and increase overall system reliability.

The performance of microinverters from top solar microinverter manufacturers can be affected by diverse weather conditions, such as temperature fluctuations, shading and humidity. To address these challenges, manufacturers have made the following advancements in technology:
Advancements in hybrid inverter technology have led to the integration of solar power generation, energy storage and grid connectivity into a single system. These hybrid inverters offer several benefits for residential solar systems:
Modern hybrid inverters feature advanced communication protocols and compatibility with a variety of solar battery technologies. This allows homeowners to store excess solar energy generated during the day in batteries for use during times of low solar production or at night. As a result, hybrid inverters play a crucial role in enhancing energy independence and efficiency in residential solar systems. When selecting the best hybrid inverter for your needs, make sure that the inverter is compatible with your chosen battery storage system.
Software plays a key role in integrating hybrid inverters with home battery storage systems. The software enables seamless communication between the hybrid inverter and the battery system, allowing for optimised energy storage and distribution based on solar production, energy demand and grid conditions. With sophisticated algorithms, the software can prioritise energy usage, automatically charge or discharge the batteries and even participate in demand-response programs to support the grid. When choosing the best hybrid inverter, it’s essential to consider the compatibility and features of its software, as it significantly influences the overall performance and efficiency of the system.
Solar inverters typically last between 10 to 15 years, though this can vary depending on the brand, quality and maintenance. High-quality inverters from reputable manufacturers like Enphase tend to have longer lifespans up to 25 years. Regular maintenance, such as keeping the inverter clean and ensuring proper ventilation, can help prolong its lifespan. Additionally, investing in inverters with robust construction and reliable components can enhance durability and reduce the likelihood of premature failure. Proper installation by qualified professionals also plays a key role in ensuring the longevity of solar inverters. More FAQs.
