Best rated solar inverters
A solar inverter is a critical part of any solar setup and choosing the right inverter is an important step in building an efficient solar energy system. At Wickes Solar, we’re here to guide you through some of the best rated solar inverters available today to help you find the perfect inverter for your home.
How do solar inverters work?
When your solar panels convert light into electricity, a direct current (DC) is generated which then needs to be converted to an alternating current (AC) for use in your home via an inverter. Most appliances in your home, from your washing machine to your lights, use AC power to operate. While there are some devices in your home that require DC power, such as televisions and computers, the electrical output of your sockets is AC, and these devices will come with their own smaller inverter.
Why do I need a solar inverter?
Also known as a PV inverter, a solar inverter is vital for regulating the flow of electricity from your solar panels to power your home. It’s the essential link between your solar energy system and your home’s power, converting DC power into AC. However, solar inverters also have several other important functions which are vital for ensuring your solar output is as efficient as possible:
Monitoring electricity production levels
Feeding AC electricity to the grid
Directing DC energy to battery storage
Monitoring the efficiency of solar panels
Detecting faults in the system
Maximising energy output
What types of solar inverters are available?
There are three main types of solar inverters available: microinverters, string inverters, and hybrid inverters. While all three are ideal for residential use, they all have specific benefits, making each one better suited to different types of solar set-ups.
Microinverters
Microinverters are small units that attach to each separate panel, making them great when you have a small, portable solar array. As each panel has its own personal inverter, microinverters can provide improved performance in situations where one solar panel may be struggling such as during adverse weather conditions or if a panel malfunctions. They’re also ideal for scenarios where certain panels may be limited by their angle or shading. However, if you do have multiple panels, it can be expensive to attach a microinverter to each panel as they cost between £50 and £150 each.
String inverters
String inverters can be connected to multiple panels so they can consolidate, and convert, the power from your whole array. String inverters effectively maintain the energy production and current of the solar panels, ensuring a reliable energy supply. String inverters are also usually the most cost-effective solar inverter solution.
However, the disadvantage with string inverters is they can only perform at the same level as the worst performing panels in your system. So, if one panel is obstructed, it’ll bring down the total power output of your system.
In these situations, a microinverter is likely more suitable, but you can also use an optimiser to boost the output of any struggling solar panels. Another option for string inverters is to install power optimisers on each solar panel to enhance the DC power across your solar system.
Hybrid inverters
Most modern solar installations will come with a hybrid inverter, as they are by far the most practical and easy to use inverter for domestic use. Hybrid inverters are essentially string inverters which also possess the ability to use a current converter to safely and effectively charge your battery array to store solar energy for when light is limited. This means you can prioritise solar energy during the day while the sun is shining, switching to stored energy from your battery, or the grid, once night falls.
What to consider when choosing a solar inverter?
When selecting a solar inverter, there are several factors you should consider to ensure you’re selecting the right inverter for your home:
Efficiency: The efficiency of an inverter measures how much energy collected by your solar panels is usable in your home. A higher efficiency rating means more of the DC power from your panels is converted into usable AC power.
Warranty: Inverters with a good warranty period usually indicate the product's durability, as well as your coverage if anything goes wrong with your solar energy system.
Monitoring Capabilities: Many modern inverters come with monitoring systems that allow you to track your system's performance in real-time. It’s worth keeping an eye out for smart home compatible inverters which will provide you with even more control.
Cost: While it's important to consider your budget, remember that investing in a higher-quality inverter can save you money in the long run through improved performance and reduced maintenance.
Compatibility: Ensure the inverter is compatible with your chosen solar panels and any future battery storage plans.
What are the top solar inverter brands?
A solar inverter is designed to last for around 10 to 15 years, so we understand that choosing the right one is an important decision. You'll want to select the right inverter for your solar energy setup, so we’ve put together a guide of the top-rated solar inverters to help you choose.
