What is Battery Storage?

A battery system enables you to store excess energy from your Solar PV system and use later on within the property. Batteries can charge from surplus solar power or from the grid. Advanced software installed within these systems use algorithms to work in conjunction with renewable energy production methods such as solar power to store surplus energy or release it to the grid.

Batteries come in all shapes and sizes and the rate at which these systems can take in and release energy is determined by the systems controller. The most common charge/discharge rate for battery systems is 3kW.

Lithium-ion batteries, which can be found in mobile phones and electric vehicles, are the most common battery types within the renewable sector. 

Depending on the type of system you have installed, if you already have solar power at your property and you’re adding batteries on retrospectively, a separate battery controller will be installed to manage the storage solution and dictate when to consume surplus power or distribute it back to the grid.

Types of Battery Installations

There are several factors that determine the type of installation you may have when adding battery storage to your property. During the initial wave of solar installations in the UK in 2010, the government introduced the Feed-in Tariff (FIT) scheme. This scheme was designed by the government to promote the uptake of renewable and low-carbon electricity generation. 

The FIT scheme does not stop you from adding battery storage to an existing installation. However, to ensure your feed-in tariff rates are not hindered, a separate inverter is installed to control the battery system.
