Home Battery Storage Across Wales
Store more of the energy your home generates, reduce reliance on the grid and prepare your property for solar panels, EV charging and future electricity costs with a professionally designed home battery system.
Make better use of the electricity your home already generates.
Solar panels are most valuable when the electricity is used inside the home. A home battery helps store excess solar generation during the day so it can be used later, rather than sending as much energy back to the grid.
3Phase designs residential battery storage around the property, solar array, household usage pattern and future plans. That could mean a solar and battery package from day one, or a battery-ready route for homeowners who already have solar panels installed.
EcoFlow PowerOcean 2 is our preferred residential battery route.
EcoFlow PowerOcean 2 gives homeowners a modern battery storage platform that can be planned around solar panels, household energy use and future home energy needs. 3Phase uses it as the preferred system where it is suitable for the property and the customer goal.
We will still review the home properly before recommending a system. The right battery route depends on roof space, solar generation, electricity usage, consumer unit position, available space and whether the homeowner wants EV charging now or later.
Smart monitoring for your home energy system.
EcoFlow PowerOcean 2 gives homeowners app-based visibility across solar generation, battery storage and household energy use. That makes it easier to see when your home is generating, storing and using electricity.
3Phase designs the system around the property first, then helps homeowners understand how monitoring can support better day-to-day energy decisions.
View battery status
Understand household use
Support smarter charging habits
Lower grid reliance. Better energy control.
Battery storage works best when it is planned as part of the wider home energy setup, not treated as a standalone box on the wall.
Use More Solar
Store surplus daytime solar generation and use more of your own electricity later in the day.
Reduce Grid Dependence
Lower how much electricity your home needs to import when solar generation is lower.
Smarter Monitoring
Understand generation, storage and household use through app-based system visibility.
EV Ready Planning
Plan battery storage alongside a future home EV charger and changing household demand.
Energy Resilience
Review whether battery storage can support a more resilient and flexible home energy setup.
Long-Term Cost Control
Protect the home from future energy uncertainty with a system designed around real use.
Is home battery storage right for your property?
Battery storage is not automatically the right route for every home. It is most useful when the system is matched to electricity usage, solar generation and the way the household uses power across the day.
3Phase will review whether the battery size, solar setup and installation route make sense before recommending EcoFlow PowerOcean 2 or another suitable approach.
EcoFlow PowerOcean installations in real home settings.
These installation images show the kind of practical details that matter on residential battery projects: equipment position, cable routes, isolation points, access and how the system sits with the property.
Wall-mounted battery position
External battery placement planned around access, clearances and a tidy cable route.
Garage battery storage setup
Indoor installation with equipment positioned neatly around storage and access.
Practical commissioning work
Residential battery installations need careful electrical work, testing and handover.
Discreet home energy storage
Battery storage can be planned to sit cleanly with garages, driveways and utility spaces.
From home survey to battery installation.
A clear residential process helps avoid oversizing, unsuitable recommendations and confusing product-led advice.
Home Energy Review
We review electricity use, solar plans, existing system details and future EV charging requirements.
Property Survey
We check practical installation considerations including available space, access and electrical layout.
System Design
We recommend a battery route based on the home, not a generic package or headline capacity.

Solar panels, battery storage and EV charging work best together.
Battery storage should be planned around the whole property. For many homeowners, the best route connects solar panels, EcoFlow PowerOcean 2 battery storage and a suitable home EV charger.
Solar Panels
Generate electricity from daylight and reduce what the home buys from the grid.
Home Battery Storage
Store excess solar generation for later household use and better energy control.
Home EV Charging
Plan EV charging around your home, driveway, tariff and wider energy system.
Home Battery Storage Wales: what homeowners should know.
Home battery storage is designed to help households use more of their own energy, especially when paired with solar panels. The right system depends on how much electricity the home uses, when that electricity is used and whether EV charging or future electrical upgrades are planned.
EcoFlow PowerOcean 2 is the preferred 3Phase residential battery route, but the recommendation should always follow a proper survey and design review. A good battery proposal should explain why the system size is suitable, where the equipment will be installed and how it works with solar PV and home energy use.
Savings vary between properties. Roof size, orientation, shading, solar generation, electricity tariff, export tariff and household demand all affect the outcome.
Home battery storage FAQs.
What is home battery storage?
Home battery storage stores electricity for later use. It is commonly paired with solar panels so homeowners can use more of the energy they generate.
Why does 3Phase prefer EcoFlow PowerOcean 2?
EcoFlow PowerOcean 2 is the preferred residential battery system for 3Phase because it supports a modern home energy route with solar, storage and smart monitoring. Suitability still depends on the property.
Can I add battery storage to existing solar panels?
In many cases, yes. The existing solar system, inverter setup, available space and electrical layout need to be reviewed first.
Do I need solar panels to have a home battery?
Not always, but battery storage is often strongest when paired with solar panels because it can store excess solar generation for later use.
Can battery storage help with EV charging?
Battery storage can be planned alongside home EV charging, but the right setup depends on your vehicle, charging pattern, tariff and household demand.
How much does home battery storage cost?
Costs depend on system size, installation complexity, electrical work and whether solar panels are included. A survey is needed for a proper quotation.
Will a battery remove my electricity bill?
No system can guarantee that. Battery storage may reduce reliance on imported electricity, but homes usually remain connected to the grid.
How do I know what size battery I need?
Battery size should be based on solar generation, household usage, available space and future plans. 3Phase reviews these factors before recommending a route.
