Solar Battery Storage Installation in Derby
Store the energy your solar panels generate and use it when you need it most. Our qualified electricians design and install battery storage systems that are safe, certified, and built around how your home uses power.
Solar Battery Storage Installation You Can Rely On in Derby
A solar battery is what turns a daytime-only generation system into a genuine energy asset, capturing surplus power you would otherwise export and releasing it after dark or during a power cut. As NICEIC Approved Contractors, we size, install, and certify battery storage systems using Sigenergy, Sunsynk, and AIKO equipment, and we handle the full electrical integration so your storage works safely alongside your existing solar array, consumer unit, and any EV charger.
“Give a Shit & Do The Right Thing” — our standard for every single customer emergency.
What a Battery Adds to Your Solar System
Solar panels only generate while the sun is shining. A battery stores the surplus so it is ready when you actually need it, turning daytime generation into all-day value.
Use Your Solar After Dark
Without storage, surplus daytime generation is exported to the grid. A battery holds that energy so you can run your home in the evening from the power your panels already produced.
Protection Against Power Cuts
Many battery systems can keep essential circuits running during an outage, so a fault on the grid no longer means a dark, cold home or a freezer full of spoiled food.
Lower Electricity Bills
By drawing less from the grid at peak evening rates and using stored solar instead, a battery reduces the amount of energy you buy from your supplier over the year.
Ready for Time-of-Use Tariffs
Some batteries can charge from the grid on a cheap overnight tariff and discharge during expensive peak hours, giving you flexibility as energy pricing becomes more time-sensitive.
What a Properly Installed Battery System Includes
A battery installation is more than bolting a unit to the wall. We specify every component to work safely with your solar array and your home’s wiring, from the storage module itself to the inverter that manages the flow of energy.
Every system we install is fully tested and certified, with monitoring set up so you can see your charge, discharge, and self-consumption in real time.
Battery Module
A lithium battery storage module from Sigenergy, Sunsynk, or AIKO, sized in kilowatt-hours to match how much surplus solar you generate and how much you use after dark.
Hybrid or AC Inverter
An inverter manages the flow of energy between your panels, the battery, and your home. A hybrid inverter combines solar and battery management in one unit; an AC-coupled inverter retrofits to an existing solar installation.
Backup / EPS Output
Where the system supports it, an emergency power supply output keeps critical circuits running during a grid outage, with a dedicated backup distribution board if required.
Monitoring & Control
An app or online portal shows live charge and discharge, solar generation, and grid import so you can see exactly how much of your own energy you are using.
Your Battery Storage Options
Whether you are fitting solar and storage together, adding a battery to existing panels, or expanding storage you already have, we design the system around your property and how you use energy.
Battery With New Solar
Homes installing solar and storage together
A single hybrid inverter manages both your panels and your battery, which is the most efficient and cost-effective way to add storage when you are fitting solar from new.
Retrofit to Existing Solar
Properties with panels already fitted
An AC-coupled battery is added to your existing solar installation so you can start storing surplus generation without replacing your current inverter or panels.
Expand an Existing Battery
Homes that want more storage capacity
If your usage has grown or you want more backup cover, additional battery modules can often be added to a compatible existing system to increase your usable storage.
We find the right solution for your property, not just the quickest fix. Our office team will talk you through the options and arrange a survey before any work begins.
