Energy on your terms
libbi isn’t just a home battery storage system, it’s eco smart. This means it makes intelligent decisions about when it provides and stores electricity based on how much energy you use, how much you generate with your solar and the electricity tariff you use.
libbi is more than storage. It gives you total control. See how much energy you use, how much you generate and synchronise with your energy tariff. Choose when to store, when to charge and where your energy should go within your home.
- Store your own solar instead of exporting it cheaply
- Charge overnight when electricity costs less
- Integrate seamlessly with zappi and eddi
You stay in control, without having to constantly manage it.

A home battery that fits around your life
Energy use changes. Your system should too. libbi is modular by design, allowing you to start with 5kWh of storage and expand up to 20kWh whenever your needs grow. Whether you add an EV, change tariff or increase your solar generation, you can adapt without replacing your system. It is not about buying the biggest battery. It is about choosing the right one for your home.

Energy should adapt to you, not the other way around. libbi continuously monitors your home’s energy flow and responds in real time, storing, charging and directing power exactly where it is needed. It is intelligent enough to optimise your savings while simple enough to feel effortless.
Use more of what you generate. Instead of sending surplus solar back to the grid for a low rate, libbi stores it for when you actually need it.
If you are on a time-of-use tariff, libbi can automatically charge during cheaper off-peak hours and use that stored energy during expensive peak periods.
When charging libbi from the grid, you can customise how much space you save for solar generation tomorrow. Set it low for that summer sun and high for those shorter winter days.
This battery is smart enough to know the difference between your house and “hungry” kit like your car. It stops your stored energy from being accidentally drained into the EV, making sure your lights, fridge and everyday appliances always come first.
libbi is a fully integrated battery and inverter system, designed to keep cables hidden and installations clean. Unlike traditional systems with separate components, libbi is a sleek, all-in-one solution that looks as good as it performs.
Built for modern homes, libbi’s compact design reduces clutter and simplifies installs. Whether in a garage, utility space, or outdoors, it blends seamlessly into your home.

One app. Total visibility.
The myenergi app connects all your devices, giving you real-time insight into your battery level, solar generation and energy usage. Set priorities. Choose charging preferences. Decide where your stored power goes.
Energy should not feel complicated.

If you choose to charge libbi from the grid, you can decide how much capacity to fill. This allows you to leave space available for expected solar generation the next day, ensuring none of your free energy goes to waste.
Export when it suits you.If you are on a tariff that rewards export, you can choose to send stored energy back to the grid when it makes financial sense. It gives you the flexibility to respond to tariff changes, rather than being locked into one approach.
libbi comes with a 10-year warranty on the battery and inverter, giving you long-term peace of mind.
Designed with premium lithium iron phosphate technology, it is built for safe, stable performance.

Your home battery storage questions answered
FAQs
No, you do not need solar panels to install home battery storage.
A battery can charge directly from the grid, especially if you are on a time-of-use tariff with cheaper off-peak rates.
That said, a battery becomes even more effective when paired with solar panels, as it allows you to store your own generated electricity instead of exporting it at a lower rate. libbi is designed to work both ways, so you can install it now and add solar later if you choose.
For many households, home battery storage is worth it if you want to reduce reliance on grid electricity and make better use of solar energy or off-peak tariffs.
A battery allows you to store excess solar for the evening and buy electricity when it is cheapest. As energy prices and tariffs continue to fluctuate, having control over when you use power can make a noticeable difference. libbi is built to automatically manage those decisions in the background, helping you get more from every kilowatt of energy.
Running your whole home from a battery during a power cut, can drain your battery faster than you’d like.
Rather than trying to power the entire house, libbi allows you to prioritise essentials so your milk stays cold, and the Wi-Fi keeps the kids happy. The power simply stays on when and where you need it most.
Most modern home batteries are designed to last many years, depending on usage and battery chemistry.
Lithium iron phosphate batteries, often referred to as LFP, are known for their stability and long cycle life.
libbi uses LFP technology and comes with a 10-year warranty on the battery and inverter, giving you long-term confidence in your investment.
Yes. One of the main benefits of home battery storage is the ability to avoid buying electricity during expensive peak hours.
If you are on a time-of-use tariff, a battery can store electricity when prices are lower and use it later when prices increase. This allows you to run your everyday essentials for less.
Modern home battery systems are designed with multiple layers of protection to ensure safe operation inside residential properties.
Most systems use lithium iron phosphate technology, which is widely recognised for its stability and safety. When installed by a qualified professional, a home battery is built to operate quietly and securely as part of your home’s electrical system.
Yes. Installing a home battery does not require you to change your energy supplier. However, some electricity tariffs may offer better savings when paired with battery storage, particularly time-of-use tariffs. You can choose whether to stay with your current supplier or switch to one that better suits your energy goals.
