WHAT IS A BATTERY STORAGE
SYSTEM AND HOW DOES IT WORK?
The significant reduction in the cost of battery storage systems in recent years means that installing a battery is fast becoming a viable option for many UK households.
When purchasing a battery storage system it is important to discuss your needs with a system designer. They will help you choose the best way to set up your system.
A battery storage system connects to a house in two main ways – DC (direct current) coupled or AC (alternating current) coupled.
A DC-coupled battery storage system is integrated into your
solar system. These systems generally have a single inverter that converts the DC electricity to AC to supply your house, or feed back into the grid.
An AC-coupled system is separate to your solar system. It
connects directly to your house wiring via its own dedicated
bi-directional battery inverter, using local AC electricity to charge the battery and then discharge it directly to your house.
Each system has its own benefits. It is best to discuss the
different options with your system designer.
