A solar battery allows you to store your generated solar electricity so you can use it anytime, day or night
For many of our solar PV customers, getting a home battery system is the obvious next step. Working families who are out during the day are especially aware that although they are generating their own clean green power, they don’t get to use it themselves. A solar battery system can dramatically increase the percentage of solar electricity that gets consumed within the home. It makes you more self-sufficient, and you can go for months without buying electricity from the national grid. Some home batteries now come with the ability to ride through power cuts, so your supply of electricity is entirely secure.
