Your quick-start guide to the future of smarter, greener energy.
Battery Energy Storage Systems, or BESS for short, are quickly becoming the cornerstone of sustainable energy in homes and businesses across the UK. And whether you’re a homeowner looking to cut costs or an installer staying ahead of the curve, there’s never been a better time to get familiar with what BESS has to offer.
As the UK’s #1 trusted energy storage brand, we at GivEnergy are here to help you make sense of it all. So, let’s dive in. Here are the top 10 things you should know about BESS.
1. What is a BESS, anyway?
A Battery Energy Storage System stores excess electricity for use when you need it most — think overnight, during power cuts, or at peak-rate times. It can work alongside solar panels, or as part of a grid-tied energy-saving setup.
2. It’s not just about backup power
Yes, BESS can protect you during an outage, but it’s so much more. A smart system can help you shift when you buy electricity at cheaper times of day, reduce your reliance on the grid, and even power your home entirely off stored energy in some cases.
3. Battery chemistry matters
The type of battery you choose impacts everything from lifespan to safety. At GivEnergy, we use LiFePO₄ (Lithium Iron Phosphate) chemistry across our battery range, which delivers:
- Up to 100% Depth of Discharge (DoD)
- Longer lifespan with thousands of cycles
- Increased safety with built-in thermal stability
- Built without rare earth materials for lower environmental impact
4. Scalability = Future-proofing
Your energy needs today might not be the same in five years. That’s why GivEnergy batteries are built to grow with you. Whether you’re starting small or planning big, you can add extra capacity as needed, whenever you want.
5. Not all installations are the same
From compact homes to large commercial setups, BESS installations come in all shapes and sizes. GivEnergy offers a wide range, from plug-and-play All-in-One units to modular commercial systems, giving you and your installer flexibility and tailored solutions.
6. Smart integration is a game-changer
Our modern BESS works seamlessly with apps, EV chargers, and smart home systems. Our GivEnergy platform offers remote monitoring, live performance stats, and intelligent automation — putting you in control of your energy.
7. Energy storage saves money
With energy prices fluctuating, a BESS helps you avoid peak rates and take advantage of low-cost or solar-generated electricity. Customers using GivEnergy systems have seen their bills drop by up to 85%! That’s more savings in the long run, which can be used for the things that truly matter.
8. BESS supports grid independence
As blackouts and grid strain become more common, a battery system gives you the resilience to ride it out. With GivEnergy, our fast switchover tech kicks in within milliseconds — keeping your lights on without missing a beat.
- Remotely manage your system from anywhere
- Set custom charge/discharge schedules
- Optimise for time-of-use tariffs
- Track real-time usage, generation, and storage
9. The lifespan is longer (and greener) than you think
Thanks to high-quality components and LiFePO₄ chemistry, GivEnergy batteries are built to last. Most of our products come with 12-year warranties, and many continue performing well beyond that with proper care.
But it’s not just about durability, it’s also about sustainability and safety. Our batteries are cobalt-free, which means fewer environmental and ethical concerns in sourcing.
And when it comes to fire resistance, LiFePO₄ stands out. Unlike other lithium-ion chemistries, it doesn’t release oxygen when heated, making it far less prone to thermal runaway or combustion. Plus, its lower operating temperature range reduces the risk of overheating, giving you a battery that’s not only longer-lasting, but safer by design.
10. You’re not alone, we’re here to help
Choosing a BESS can feel overwhelming, but we’re here to make it simple. From our UK-based support team to our network of trusted installers, we make sure your journey from quote to install is smooth, supported, and stress-free.
And to make things even easier, we’ve just launched the GivEnergy Collections Thames, Humber, and Trent — our pre-configured energy ecosystems tailored for varying energy needs. Each includes everything needed for a seamless setup, from inverters and batteries to essential accessories. Whether you’re a homeowner looking for a ready-to-go solution or an installer aiming for efficient installs, the Collections take the guesswork out of system design.
Power your future with confidence
