Grant Store’s solar inverter solutions
As experts with decades of experience, we can help you decide which solar inverter would be the most effective one for your solar energy installation.
String inverters
A string of solar panels is a group of panels that are connected in series, and they must be at the same pitch and orientation in order to work efficiently.
Microinverters
Unlike traditional string inverters, microinverters have an inverter for each individual solar panel. This makes microinverters a good option for homes with complex roof geometries or shading issues.
Hybrid solar inverters
A good option for homes with solar battery storage, as they can convert DC electricity into AC electricity for your home’s appliances, and store surplus power in a solar battery or sell it to the grid.
Power inverters
Power inverters pass the DC power from PV solar panels through a string inverter. This makes them a cheaper alternative to micro-inverters and a more affordable way to improve your solar panels’ performance.

How inverters for solar panels work
- PV solar panels convert sunlight into direct current (DC) electricity
- The solar inverter converts the DC electricity from the solar panels into alternating current (AC) electricity
- The AC electricity is either used to power your home appliances or sold back to the grid
- The inverter also regulates the flow of electricity from the solar panels, ensuring that it’s safe and reliable

Advantages of adding a solar inverter to your solar setup
Solar panels are pretty useless without a solar inverter to switch the polarity of the electricity that they generate. Devices such as solar-powered lights and water pumps run on DC power, but you couldn’t power your home appliances or sell any excess electricity back to the grid without an inverter. Here are five other advantages to having one:
Save money on your energy bills
An inverter can help you save money on your energy bills by converting the solar energy from your panels into usable electricity
Reduce your carbon footprint
It can also help you reduce your carbon footprint by minimising your reliance on fossil fuels
Increase your home's value
By making it more energy-efficient and environmentally friendly, an inverter can actually increase the value of your home
Decrease your dependency on the grid
Become energy independent by storing excess solar energy for use during times when the grid is down
Improve the reliability of your power suppl
An inverter can improve the reliability of your power supply by providing backup power during power outages

FAQs
You must have lots of questions. We’ve answered some of the most commonly-asked questions about solar panel inverters here, but please speak to the team if you have any more.
What does a solar inverter do?
A solar panel inverter converts direct current (DC) electricity from solar panels into alternating current (AC) electricity, which is the type of electricity that is used to power appliances in homes and businesses. It also regulates the flow of electricity from the solar panels, ensuring that it’s safe and reliable. It allows you to power your home appliances and sell any excess electricity back to the grid, provides backup power during power outages, monitors the performance of your solar system, and sends alerts if there are any problems.
What type of solar inverter do I need?
This will depend on three things: The size of your solar system, its location, and your budget. We’re experts in all things solar energy installations, solar inverters, and battery storage, so speak to us before making any decisions, and we’ll make sure you get the best solution for your electricity needs.
What is the difference between a solar inverter and a hybrid solar inverter?
The main difference is that a hybrid solar inverter can store excess solar energy in a battery, whereas a regular solar inverter can’t do this. They are a bit more expensive to buy, but if you want to store energy or even sell it to the grid, then they’re well worth considering. Speak to the team for a free quote on both, and we’ll help you decide which solar inverter would be most financially viable for you.
How do I know what size inverter I need for my solar system?
This depends on the following factors: The size of your solar array, the type of inverter, the location of your solar array, and your budget. As a general rule of thumb, though, the inverter size should be equal to the output of each solar panel in your solar array. If you’re in any doubt about which solar inverter you should get to complement your PV solar panels, then we’ll only be too happy to help, so get in touch on 01942 918 844.
