Your solar.
Ready for the evening.
You’ve already invested in solar. A battery helps you use more of the electricity your panels produce — and buy less from the grid when you need it most.
Friendly advice. A quote for your home. No obligation.
A real Sunergy installation. A smarter use of everyday space.
Qualified people. Recognised standards.

“Prompt quotation. Competitive price. Good communication. No fuss installation of battery and inverter to existing solar.”
Keep the sunshine.
Use it when you’re home.
Your panels often produce spare electricity during the day. A battery gives that energy somewhere to go until you need it.
Make it by day.
Your solar powers your home first. Electricity you don’t need straight away can charge your battery.
Save some for later.
The battery stores that spare solar instead of sending it straight to the grid. Surplus can still export when the battery is full.
Enjoy it after sunset.
Stored energy helps power your evening — from cooking dinner to settling down in front of the TV.
You’ve made the energy.
Make more use of it.
Self-consumption simply means the share of your solar electricity you use at home. Adding a battery can increase that share by moving spare daytime energy into your evenings.
Every unit of stored solar you use can replace electricity you would otherwise buy. The value depends on your import price, any export income you give up and battery losses.
Same panels.
More solar used at home.

Illustrative shares of total solar generation only. The remainder can include export and storage losses. Your result depends on generation, when you use electricity, battery size and efficiency.
Buy less electricity.
Take more control.
When electricity prices rise, buying fewer units from the grid can help soften the impact. A battery gives you more control over when you buy energy and when you use your own.
We’ll look at your solar, your tariff and your household routine to explain what a battery could save in your home.
A battery won’t remove your standing charge or protect you from every price change.

Solar savings.
Cheaper charging.
Extra rewards.
An illustrative year using stored solar and off-peak electricity, with optional Axle rewards.
About £1,000
combined annual savings & gross rewards*
£750 modelled electricity savings + £250 illustrative Axle rewards. This is an example, not a typical result or guarantee. Additional Axle-related energy costs reduce the combined benefit.
Based on one FOX ESS EP12 with 11.52 kWh nominal capacity. We model 10 kWh supplied to the home per day on average (3,650 kWh/year), not the full nominal capacity. This is a throughput assumption, not a manufacturer’s usable-capacity specification.
Half of the annual energy supplied by the battery comes from surplus solar (1,825 kWh); half comes from off-peak charging (1,825 kWh). The actual daily split varies by season. This assumes sufficient solar surplus, charging time and demand at the higher rate.
Illustrative rates: 30p/kWh peak import, 7p/kWh off-peak import and 10p/kWh metered solar export. Assumed round-trip efficiency: 90%, not a product specification. Both comparisons use the same tariff.
Solar: (1,825 × £0.30) − (1,825 ÷ 0.90 × £0.10) ≈ £345. Off-peak: (1,825 × £0.30) − (1,825 ÷ 0.90 × £0.07) ≈ £406. Combined electricity benefit ≈ £750, with the displayed breakdown rounded to £345 + £405.
Electricity figures account for charging losses and forgone solar export income. They exclude standby use, installation and finance costs, degradation, maintenance and replacement. Actual savings depend on your system, tariffs and usage.
*£250/year is Sunergy’s illustrative Axle reward assumption, not a guaranteed payment. Eligibility, event availability and terms apply. Gross rewards include any monthly top-ups; these are not added again. Extra charging costs or displaced home-use savings must be deducted. How Axle rewards work ↗
“Will a battery work
with my system?”
In many cases, yes. We can assess a battery system that works alongside your existing solar, without replacing your panels.
You don’t need all the technical answers.
Tell us what you know. A photo of your inverter and an electricity bill can help us work out the next step.
Not always. An AC-coupled battery has its own inverter and can work alongside many existing solar systems. We’ll check your equipment before recommending an arrangement.
Tell us if you receive FIT payments. We’ll review the generation meter and proposed connection. Confirm any proposed changes with your FIT provider before installation.
We’ll assess a suitable location, such as a garage or an outside wall where the equipment and site allow. Space, access and installation requirements all need checking.
Good advice comes before a brand.
We’ll help you compare capacity, charging power and installation cost. The right size is based on your energy use and available solar surplus.

No solar?
There’s another way to save.
A home battery can also charge from the grid during a cheaper tariff window. You then use that stored electricity later, instead of buying as much at the more expensive rate.
It’s a separate route to battery savings — no rooftop panels required.
Make the most of cheaper hours.
Your battery charges during the lower-cost periods available on a suitable tariff.
Keep expensive imports down.
Stored electricity supplies your home later. We check the price gap, charging losses and your usage to assess the potential benefit.
Savings depend on tariff eligibility, rates, charging time, battery power and household demand. A battery is an investment; installation cost matters too.
Real homes. Thoughtful installations.
From the first conversation to the handover, we’ll explain your options, agree the installation and help you get familiar with your battery.
Installation location and layout are subject to assessment. Directors James and Mason bring more than 16 years’ combined renewable-energy experience.
Feel clear before you decide.
We’ll assess your electricity use, solar surplus, import and export rates, and the proposed battery. Savings vary: a bigger battery does not automatically mean better value. Use the calculator in our savings section for an initial illustration.
Usually, yes. Solar generation changes through the year, your battery has a limited capacity and your home may need more power than it can supply. The aim is to reduce or shift suitable grid imports.
Many systems can do both with a suitable tariff and configuration. We’ll check the charging window, your solar surplus and the battery’s capacity so the two work together.
Only with a suitable backup arrangement. It isn’t standard on every installation. Let us know which essential circuits matter to you so we can discuss the extra design and equipment needed.
We’ll contact you to understand your home and existing equipment, assess the options and explain a proposed system and price. You don’t need to choose a battery model before getting in touch.
