The Sunsynk Data Logger app allows you to get the most out of your solar panels and batteries. On the app, you can track how much energy your panels are generating and receive tips on how to save money and reduce your energy spend.

8.?Huawei Luna 2000-10

Solar batteries can be bulky so if you are short on space, the Huawei Luna is a great option. The unit is only 150mm thick and can easily be installed in a space with limited space. The battery is waterproof and can be mounted on the wall to save even more space.

Comparison between 8 Best Home Battery Storage Systems

The table summarises all of our key findings for each battery type.

How Do Home Batteries Work?

The principle is very simple. Only 30% of solar generated electricity is used within the home so it is only natural to want to use more of your energy.

Batteries capture solar electricity that would otherwise be sent back to the grid, this is often known as excess energy. Instead of then purchasing energy from your provider, the stored energy can supply power to your home throughout the night.

Do I Need a Home Battery if I Already Have Solar Panels?

Home batteries are not essential. However, they are a great tool for getting the most out of your energy. Solar panels only create energy in daylight. Buying a battery means you will be able to utilise this energy during hours when the sun is not shining.

What Size Battery Do I Need?

An average three bedroom household requires an 8kWh solar battery. The actual size battery for you will depend on the amount of energy you use. Experts can help you work out this figure.
