In short... What are home batteries?

An emergency home battery is a wall‑mounted, rechargeable energy storage system connected to your consumer unit that can power key circuits during a power cut. It can store electricity from the grid or from solar panels and release it later when your home needs it.

  • Charge from the grid when your tariff is cheaper (off‑peak).
  • Discharge into your house when the tariff is expensive (peak).
  • Optionally also store excess solar if you add PV now or later.

How does the setup actually work?

The smart controller in the batteries will activate charging overnight when your electricity tariff is cheaper, then during the day when electricity from the grid costs you substantially more, the batteries will start using the stored energy. The system comprises 3 main components involved:

Charging Phase
  • During off peak hours, the system imports electricity from the grid (or solar) and converts it from AC to DC to charge the battery.
  • Smart controls or the inverter follow a schedule or live tariff data to decide when to charge.
Storage
  • The battery holds that energy until it’s needed, with modern lithium‑ion systems typically having good round‑trip efficiency so most of what you put in is available later.
Discharge Phase
  • When your home demand is high or the tariff is expensive, the inverter converts the DC power back to AC and feeds it into your home’s consumer unit.
  • Your appliances then draw from the battery first, reducing or eliminating imports from the grid at the expensive rate.
Optional Backup Phase
  • These smart batteries can be configures so if the grid fails, they automatically switch on and keep your essential circuits alive.

Lifespan & Performance

  • Most lithium‑ion home batteries are designed for many thousands of charge/discharge cycles before dropping to around 70–80% of original capacity.
  • Round‑trip efficiency is typically high, meaning a large portion of the energy you store is actually available the same day still, but there are always some conversion and storage losses.

Take Control,
In 3 Simple Steps.

01

Assessment & Design

A qualified engineer evaluates your home's energy usage, existing solar setup, and electrical panel to determine the ideal battery capacity.

They will design a tailored system that meets your daily power needs and backup requirements.

02

Professional Installation

Certified technicians mount the battery unit, typically in a garage, utility room, or on an exterior wall, and connect it to your electrical system via a smart inverter.

The team then tests the system to ensure seamless integration with the grid and your home's power supply.

03

Connection & Monitoring

The system is commissioned and linked to a mobile app, allowing you to track your energy storage, solar generation, and savings in real time.

Your installer will also handle any necessary final certifications and registrations with your local utility grid.

Frequently
Asked Questions.

You can absolutely run battery‑only; many UK installations now focus on grid‑charged batteries plus smart tariffs, with or without solar.

If your system and tariff support it, you can export surplus power under schemes like Smart Export Guarantee or specific supplier tariffs, but most people aim to self consume first. .

A rough starting point is 1–1.5 times your typical evening/night usage in kWh; many UK homes settle around 5–10 kWh, but high usage homes go higher.

Systems are designed with built‑in protection and must be installed to UK standards; lithium‑ion systems use a BMS and are enclosed, but they must be installed by qualified engineers.

Common locations are garages, utility rooms, or suitable exterior walls, depending on the IP rating and manufacturer guidance.

Some systems are wired as pure “grid‑following” (no backup) while others can isolate and power selected circuits; this needs to be planned with your installer.

You’d look at usable capacity, warranty (years and cycles), integration with your supplier’s tariff, app/software quality, and whether you want AC or hybrid inverter configurations. But don't worry, we are here to help guide you and make all the necessary recommendations.
