This is live operating data from a real FOX ESS system installed and supported by Sunergy. It shows how solar, site demand, battery storage and the grid interact throughout the day.

Different starting points. Different answers.
You do not need to know which product you need before speaking to us. Start with your situation and we can work from there.
Add battery storage to keep more of your generation.
A retrofit battery can capture more of the electricity your solar already produces and make it available later in the day.
- Retrofit AC-coupled storage
- Increase solar self-consumption
- Optional off-peak grid charging
Used later. Capture more surplus generation instead of exporting it immediately.
With solar or without it, storage is about using energy at the right time.
There are two main reasons people add battery storage: capture electricity they already generate, or move grid consumption away from more expensive periods. Some homes do both.
A battery can still make sense.
Battery storage does not have to depend on solar. A system can charge from the grid during cheaper off-peak periods and supply the home later when electricity costs more.
This can be especially useful for households on time-of-use tariffs, higher evening demand, or those who want to add solar at a later date.
- Charge during lower-cost tariff windows
- Use stored energy during expensive periods
- Add solar later if the property suits it
Keep more of what you generate.
Solar often produces electricity when the home is using less of it. A retrofit battery can capture more of that surplus and make it available later in the day.
For many existing PV owners, battery storage is the natural next upgrade because it can increase self-consumption without replacing the solar array.
- Retrofit to many existing PV systems
- Increase use of your own solar generation
- Expandable storage options available
The best systems work together.
Solar, batteries, EV charging and tariffs are most useful when they’re designed as one system rather than separate products.
Renewable energy is technical. The advice should still be easy to understand.
We built Sunergy around straightforward recommendations, sensible system design and support that continues after the installation is finished.
Advice before equipment
We start with the property and energy use, then decide what technology is worth considering.
Manufacturer-level experience
Our background in the battery storage industry means we understand the equipment as well as the installation.
Support after installation
We service, repair, upgrade and troubleshoot renewable systems — including systems installed by other companies.
Residential and commercial
The same practical approach applies from a home battery retrofit to larger commercial solar and BESS projects.
Lower bills. More control.
Battery storage, solar PV, EV charging and upgrades designed around your household, tariff and existing equipment.
Turn energy into an asset.
Commercial solar, battery storage, EV infrastructure and O&M designed around site demand and electrical infrastructure.
See how these systems work in the real world.
Two very different projects, but the same principle: the system has to be designed around how the property or site actually uses energy.
Battery storage without solar panels.
This case study shows how battery storage can work as a standalone energy system — charging when electricity is cheaper and supplying the home later when grid power costs more.
It’s a useful example for customers who want more control over their energy use but do not necessarily want, or cannot install, solar PV.
Commercial battery storage in action.
This commercial project shows the other end of the scale: battery storage designed around a business site where demand, electrical infrastructure and operating profile all matter.
Commercial systems are not just larger home batteries — the design case is different and needs to be treated that way.
Energy projects built around the site, not a brochure.
Commercial projects need more than a product recommendation. Load profile, available capacity, point of connection, export limits, operating hours and future demand all matter.
Sunergy supports businesses with rooftop PV, behind-the-meter battery storage, EV infrastructure, DNO liaison and ongoing O&M.
Typical commercial requirements
- Rooftop and ground-mounted solar PV
- Behind-the-meter battery energy storage
- Peak shaving and load shifting strategies
- Commercial EV charging infrastructure
- DNO / G99 / G100 coordination
- Servicing, monitoring and O&M
Important: final commercial system sizing should follow site data and technical survey rather than a headline battery capacity.
Clear advice from first conversation to aftercare.
No unnecessary complexity. We keep the process understandable and make sure you know what is being recommended and why.
Understand
We start with your usage, existing system and what you want to achieve.
Design
We recommend the system that fits the property, tariff and electrical infrastructure.
Install
Our team installs, commissions and provides the relevant certification.
Support
We remain available for servicing, upgrades, faults and future expansion.
A few things people usually want to know first.
If your question is more specific, send us the details and we’ll give you a straight answer.
Start with a conversation, not a product.
Tell us what you have, what you want to achieve and what matters most. We’ll help work out the right next step.
