- One of many options
Sigenergy is what we'd pick, not the only thing we fit.
We’re engineers first, so we stay independent of any single manufacturer. We’ll recommend the product that genuinely suits your property, budget and goals, and we’re always expanding the range we install.
Overview
What battery storage actually means for you.
A home battery captures the energy you generate or buy cheaply and releases it when power is most expensive, typically the evening peak. Paired with a time-of-use tariff, it lets you charge overnight at low rates and run your home on stored energy by day. We size storage to your routine, integrate it with new or existing solar, and configure intelligent charge logic so it works automatically.
Overview
- Solar owners exporting surplus cheaply
- Properties wanting backup during outages
- Homes on off-peak overnight tariffs
- Households with high evening energy use

How It Works
From first call to switched on.
A clear, managed process for every solar pv project, no surprises.
01
Energy profile review
We analyse when and how much energy you use to recommend the right usable capacity. No over- or under-sizing.
02
System design
We confirm compatibility with your solar and tariff, then plan placement, backup circuits and electrical connections.
03
Installation
The battery and any gateway hardware are installed and wired by our certified engineers, typically within a day.
04
Smart configuration
We program charge and discharge schedules around your tariff and set up real-time app monitoring.
Why choose battery storage?
The benefits our customers value most.
Power through peak hours
Avoid the most expensive tariff windows by drawing from stored energy.
Backup when it matters
Keep essential circuits running during a power cut.
Maximise your solar
Bank daytime generation instead of exporting it cheaply.
Smart, automatic control
Charges and discharges intelligently based on your usage and tariff.
FAQs
Battery Storage questions, answered.
Still unsure? Our team is happy to talk through your specifics with no obligation.
Can I add a battery to my existing solar?
Almost always, yes. We assess your current inverter and either integrate AC-coupled storage or recommend a hybrid upgrade where it makes sense.
Will it keep my home running in a power cut?
With a backup-capable configuration, yes — typically essential circuits like lighting, fridge and sockets, or whole-home depending on capacity and setup.
Do I need solar to benefit from a battery?
No. Even without solar you can charge overnight on cheap off-peak rates and discharge during expensive peak hours to cut costs.
The complete system
Better on its own. Unbeatable together.
Solar, storage and EV charging are designed to work as one. Solar is the foundation, it generates the clean, free electricity that powers your home and feeds everything else in the system.

Why fit the full ecosystem?
Each part lowers your bills on its own, but together they turn your home into a self-sufficient energy loop, where the power you generate fuels everything from your kettle to your car.
- One connected system, designed and fitted by a single team
- Generate by day, store the surplus, charge your car for next to nothing
- Less reliance on the grid and far smaller bills year-round
- Add each part now or in stages, every install is upgrade-ready
