HOME BATTERY STORAGE

Home Battery Storage
Designed Around You

Store solar energy and low-cost off-peak electricity, then use it when electricity costs more. We design battery systems around your actual consumption, tariff, lifestyle and future energy needs.

Designed around your energy use

Consumption data, tariff analysis, solar generation, peak demand and future energy needs.

 EVIDENCE-LED DESIGN

The Right Battery Size Starts With Your Energy Data

Every home uses electricity differently. We analyse when and how much energy you use before recommending battery capacity or inverter power, so your system is designed around your home rather than a standard package.

Half-hourly consumption and electricity bills

Solar generation and current electricity tariff

EVs, heat pumps and future energy demand

Your battery design can include

Daily Energy Use

How many kWh your home actually consumes.

Tariff Analysis

When electricity is cheapest to buy.

Load Profile

When during the day you use electricity.

Battery Capacity

The useful storage capacity your home needs.

Solar Generation

How much surplus solar is available to store.

Inverter Power

The power required to support your household loads.

SMARTER ENERGY USE

Make Energy Work Harder

Store Solar Energy

Capture surplus solar generation and use it later.

Buy Energy Off-Peak

Charge your battery when grid electricity is cheaper.

Reduce Peak-Rate Imports

Use stored energy when electricity costs more.

Increase Energy Independence

Reduce your reliance on electricity imported from the grid.

Prepare for Future Demand

Plan for EVs, heat pumps and increasing electricity use.

BATTERY CAPACITY VS POWER

A Bigger Battery Doesn’t Necessarily Mean More Power

Battery capacity and inverter power are two different things. Both need to be correctly sized for your home.

30 kWh
Battery Capacity

How much energy the battery can store.

VS

8 kW
Inverter Power

How much power the system can deliver at one time.

Why does this matter?

A home can have a large battery and still import electricity from the grid if the inverter cannot supply the combined demand of appliances running at the same time.

Induction Hob • Oven • Heat Pump • EV Charger • Hot Tub • Swimming Pool

We size both the battery capacity and inverter power around your tariff and  actual and future energy requirements.

SMART TARIFF OPTIMISATION

Your Battery Can Buy Electricity When It’s Cheapest

A battery can do more than store solar energy. By charging when electricity is cheapest and supplying your home during expensive periods, it can reduce the amount of peak-rate electricity you buy from the grid.

1 — CHARGE

Charge at Lower-Cost Times

Charge from surplus solar or lower-cost off-peak electricity.

2 — STORE

Hold Energy for Later

Keep stored energy available for the periods when grid electricity costs more.

 

3 — USE

Reduce Peak-Rate Imports

Power your home from the battery instead of buying higher-cost grid electricity.

The best strategy changes with the seasons.

In summer, solar may provide most of the battery charging. In winter, lower-cost overnight electricity can become much more important.

We design and configure your battery around your electricity tariff, energy consumption and seasonal generation.

BATTERY OPTIONS

Adding a Battery to New or Existing Solar

Battery storage can be designed as part of a new solar installation or added to an existing system. The best approach depends on the existing inverter, available electrical capacity, electrical layout and how you want the battery to operate.

New Solar + Battery

The battery and solar inverter can be designed together from the outset, allowing the whole system to be sized around your consumption, generation and tariff strategy.

 

Adding a Battery to Existing Solar

An AC-coupled battery can often be added without replacing the existing solar inverter, making it a practical option for many established solar installations.

We assess the existing system first — we do not replace equipment unless there is a technical or financial reason to do so.

BACKUP POWER

Keeping Essential Circuits Running During a Power Cut

Battery backup can keep selected circuits powered when the grid fails. The correct solution depends on what you want to keep running and how much power those loads require.

Essential Circuits

Lighting, broadband, refrigeration, heating controls and other priority loads can be selected for backup.

 

Power Requirements

We calculate the simultaneous load so the inverter and backup equipment are correctly sized.

 

Backup Strategy

Whole-home backup is not always necessary. We design the level of backup around what is actually useful to you.

Backup should be designed around resilience requirements — not added simply because the equipment supports it.

WHY GREEN ENERGY SYSTEMS

Designed Around Your Energy Use — Not a Standard Package

We design each battery system around the property, the customer and the way energy is actually used. Our recommendations are based on measured consumption, future plans, tariff strategy and system performance.

Evidence-Led Design

We use real consumption data wherever available rather than relying only on annual estimates.

 

Future-Proof Planning

EVs, heat pumps and other planned loads are considered before the system is sized.

 

Tariff Optimisation

The battery is configured around the electricity tariff as well as the solar system.

 

Ongoing Optimisation

We explain the system, monitor performance and help optimise settings as tariffs, usage and requirements change.

Our aim is not to sell the biggest battery — it is to design the system that gives you the best technical and financial outcome.
