Battery Storage Installation in Cheshire & North Wales

Store the energy you generate. Use it when you need it.
Pay less to the grid.
Solar panels generate electricity during daylight hours — but that's not always when your home or business is using the most power. A battery storage system solves that, storing your surplus solar energy so you can use it in the evening, overnight, and on low-generation days.
The result is a significant boost to your solar savings, greater energy independence, and a system that works harder for you around the clock. If you already have a solar installation with a Feed In Tariff (FIT), we can add an AC coupled battery storage system so that it doesn’t affect your FIT payments.
At Solartech Installations, we supply and install leading battery storage systems for homes and businesses across Cheshire, North Wales, and the wider North West — as a combined solar and battery installation, or as a standalone addition to an existing solar system.

How Battery Storage Works

Without a battery, any solar energy your panels generate that you don't immediately use gets exported to the grid — often for a few pence per unit. A battery captures that surplus energy instead, storing it for use later in the day when your panels aren't generating.
There are two types of battery storage system:
DC Coupled — the battery is connected directly to your solar panels via the inverter. This is the most efficient configuration and is the standard choice for new solar and battery installations. Energy goes straight from your panels into the battery without additional conversion losses.
AC Coupled — the battery connects to your home's AC supply rather than directly to the solar array. This makes it suitable for homes that already have an existing solar system, or for households without solar who want to take advantage of cheaper overnight energy rates.

More Ways to Save — Force Charging & the Smart Export Guarantee

Force charging overnight
Using a smart energy tariff, such as Octopus Energy's off-peak rates, you can programme your battery to charge overnight at a cheaper rate, then use that stored energy during the day when rates are higher. This is particularly valuable during winter months when solar generation is lower but energy usage is at its highest.
Smart Export Guarantee (SEG)
Once your home demand is met and your battery is fully charged, any remaining surplus energy is exported to the grid. Through the Smart Export Guarantee, your energy supplier pays you for every unit you export, putting money back in your pocket for energy that would otherwise be wasted.

Key Benefits of Battery Storage

Use more of the solar energy you generate

stop exporting cheap and buying back expensive

Reduce your grid dependency

draw less from the grid, especially in the evenings

Force charge overnight

at cheaper off-peak rates to maximise savings year-round

Earn through the Smart Export

for any surplus you do export

Scalable systems

storage capacity can be expanded as your needs grow

Remote monitoring

track your generation, storage, and consumption in real time via app

Works without solar

AC coupled batteries let you benefit from cheap overnight rates even without panels

Battery Storage Without Solar Panels

You don't need to have solar panels to benefit from battery storage. An AC coupled battery system allows you to charge from the grid overnight at cheaper off-peak tariff rates and use that stored energy during peak-rate daytime hours — reducing your bills even without generating your own electricity.
If you're considering solar in the future, an AC coupled battery can be seamlessly integrated with a solar installation when you're ready.

Frequently Asked Questions

How much does a home battery storage system cost?

Battery storage costs vary depending on capacity, brand, and whether it's being installed alongside solar or retrofitted to an existing system. We'll provide a clear, itemised quote as part of your free survey.

What size battery do I need?

The right battery size depends on your household energy consumption, your solar system output, and how much of your usage falls outside daylight hours. We'll calculate this for you during your survey.

Can I add a battery to my existing solar panels?

Yes. If you already have a solar PV system, we can retrofit a battery storage system — either DC or AC coupled depending on your existing setup. We'll assess your current installation and recommend the best solution.

How long will a battery last?

Most modern home batteries are rated for 6,000+ charge cycles, which typically equates to 15–20 years of normal use. All systems we install come with manufacturer warranties.

Will a battery provide backup power if the grid goes down?

Some battery systems offer backup/islanding functionality, which can power essential circuits during a grid outage. This varies by product — we'll advise on which systems offer this if it's a priority for you.

Is battery storage eligible for zero-rated VAT?

Yes — battery storage installed alongside solar panels currently benefits from zero-rated VAT, confirmed until March 2027.
