Benefits of installing a battery storage system in your home

Backup power

A battery storage system can be used to keep your home running during a power cut. Most modern-day batteries can be used as an EPS (emergency power system) and can work on or off grid. In the event of a power outage the battery isolates itself from the incoming electricity supply and reverts into what is known as “island mode”. In this state it will safely deliver power to your home, whilst remaining entirely isolated from the incoming supply so that it poses no danger to the people working to repair the incoming supply. If the power cut happens during daylight hours and you have solar panels installed, the battery can continue to store solar energy even when the grid is down. When the power cut is resolved, and the grid comes back online, the battery will automatically come out of “island mode” and resume normal function. This process is done automatically, with no need for additional changeover switching. You won’t even see the lights flicker!

Revenue Generation

A battery storage system can be used as a means to generate additional revenue by simply buying electricity from the grid at a reduced “off peak” price, during times of low demand. The energy purchased can then be sold back to the grid to help reduce the pressure during times of higher demand, for a higher price than it was purchased for. We call this energy arbitrage!

Reduce Energy Bills

Energy bills can be substantially reduced with the installation of a battery storage system. From storing solar power for use later to buying power low and selling high, with a well-designed and costed battery storage system you are guaranteed to make savings on your energy bills.

Frequently Asked Questions

Quite simply a battery storage system stores electricity either from generation by solar panels, or directly from the grid. In short, you can store electricity that you produce yourself for use later on, or you may decide to buy electricity overnight using a reduced rate tariff, for use later on in the day, during peak hours, thereby greatly reducing your electricity bills.
Ideally, a battery storage system should be installed in a non-inhabited room, such as a garage or outhouse. Many battery systems are rated to be installed outdoors. Regulation has recently been introduced in the form of PAS63100:2024 advising that battery systems should no longer be installed in loft spaces or escape routes. We will survey your property and advise where a battery can best be situated for you.
Contrary to popular belief you do not need solar panels to benefit from a battery storage system. Although the two complement each other beautifully, in certain situations solar panels are not viable; for instance, if you live in a flat, or if your roof is not ideally suited to solar. A battery storage system stores electric energy and will quite happily store energy purchased directly from the grid. But why would you want to do that? In a bid to level out daytime and nighttime electrical consumption, off-peak tariffs are now available to encourage battery storage system owners to fill up their batteries by buying electricity overnight, so that they do not have to buy it during the day. This takes pressure off the grid to provide so much power during peak usage times and benefits battery storage system owners by allowing them to buy electricity at a reduced price. This arrangement works particularly well for electric vehicle owners as they are able to attract even cheaper off-peak electricity prices in the form of “EV Tariffs”, for as little as 7.5p per kWh in some cases, allowing them to fully charge battery storage systems for a fraction of the cost of peak time electricity. If you want to know more about how owning an electric vehicle can benefit your solar and battery installation and reduce your payback time just give us a call and we’ll be glad to tell you more.
Modern day battery storage systems are safer than ever. Lithium Iron Phosphate (LiFePO4) is a type of Lithium-ion battery that uses Iron Phosphate as a cathode. This type of battery is safer, requires no maintenance and has a better charge and discharge rate than any other battery configurations. If you are wondering what a lithium-ion battery is and whether or not it is safe, then think about what’s been powering our mobile phones since the early 1990s.
Battery storage systems are usually guaranteed for a minimum of 10 years, if installed by qualified technicians.
Solar and battery inverters are usually guaranteed for a minimum of 5 years, if installed by qualified technicians.
All of our installations are further covered by a two-year workmanship warranty which guarantees the installation is undertaken to the highest professional standards.
