Battery Storage Installation Essex & East London

Without battery storage, up to 50% of the electricity your solar panels generate during the day is exported to the grid at low SEG rates — instead of being used to power your home in the evening. A home battery system captures this excess generation and stores it, so you can use your own solar power even after the sun goes down.

KLIC ELECTRICAL installs home battery storage systems as a retrofit to existing solar installations or as part of a new solar and battery package. We work with the leading battery brands — GivEnergy, Tesla Powerwall, Solax, and Fox ESS — and design systems around your household's energy consumption pattern to maximise self-consumption and minimise grid reliance.

What's Included in Your Battery Storage Installation

Battery System Supply

We supply leading battery systems including GivEnergy, Tesla Powerwall 3, Solax X-Hybrid, and Fox ESS — selected based on your storage capacity requirements and budget.

Professional Installation

Wall-mounted installation in your garage, utility room, or external enclosure — including all associated cabling, isolators, and battery management system wiring.

Solar Integration

Full integration with your existing solar inverter or as part of a hybrid inverter system — ensuring intelligent charge and discharge management based on solar generation and consumption.

Smart Monitoring Setup

We configure your battery's smart monitoring app so you can track real-time charge status, energy flows, and savings from your smartphone.

Backup Power Configuration

For supported battery systems (including Tesla Powerwall), we can configure automatic backup power — keeping critical circuits live during a grid power cut.

MCS Certificate

Battery installations integrated with MCS-certified solar systems are issued with an MCS certificate — required for SEG applications and insurance documentation.

Choosing the Right Battery for Your Home

Not all batteries are equal — capacity, chemistry, warranty, and inverter compatibility all matter.

Usable vs. Total Capacity

Battery manufacturers quote total capacity, but usable capacity (what you can actually store and use) is typically 5–10% less. A GivEnergy 9.5kWh battery, for example, provides around 9.0kWh of usable storage — enough for most households to cover evening and overnight consumption.

Inverter Compatibility

AC-coupled batteries (like Tesla Powerwall) work with any existing solar installation regardless of inverter brand. DC-coupled batteries require compatibility with your inverter or a hybrid inverter system. We check compatibility before specifying your battery.

Warranty & Chemistry

All batteries we install use lithium iron phosphate (LFP) or lithium NMC chemistry with 10-year warranties and at least 4,000 full charge cycles. We do not install budget batteries with short warranties or unknown cycle life ratings.

Why KLIC?

Battery Storage Specialists in
Essex & East London

KLIC ELECTRICAL has installed dozens of home battery storage systems across Essex and East London. Our MCS certification, technical knowledge of leading battery platforms, and honest approach to system sizing means you get a battery that actually improves your self-consumption — not just an expensive box on the wall.

Can I Add a Battery Without Solar Panels?

Yes. A battery can be charged exclusively from the grid — using low-rate overnight electricity (e.g., Octopus Go or Economy 7) to fill the battery, then discharging it during peak-rate evening hours. This can save £200–£400 per year on a time-of-use electricity tariff. It works best for homes without solar, or as a complement to solar for maximising savings.

Battery Storage FAQs

Your battery storage questions answered by our Essex & East London renewables team.

A typical AC-coupled home battery system (such as GivEnergy 9.5kWh or Tesla Powerwall 3) costs between £3,500 and £6,500 installed, depending on battery capacity, brand, and installation complexity. We provide a fixed-price quote after reviewing your solar setup and consumption data.

For most UK households, a battery in the 5–10kWh usable capacity range is sufficient to store excess daytime solar generation and cover evening consumption. If you have a larger solar system or high overnight electricity use, a 10–15kWh system may be more appropriate. We size your battery based on your actual generation and consumption data.

Yes, but only if the battery is specifically configured for backup operation. Tesla Powerwall 3 and GivEnergy batteries both support backup power modes that automatically disconnect from the grid and continue powering your home during an outage. This feature must be enabled and wired correctly at installation — we set this up as part of commissioning if you request it.

A standalone battery installation (retrofitted to an existing solar system) typically takes 4–6 hours. If a new hybrid inverter is also required, the installation may take a full day. We cause minimal disruption to your home, and everything is left clean and tidy on completion.

In most cases, yes. AC-coupled batteries like Tesla Powerwall and GivEnergy's AC battery models are compatible with virtually any existing solar installation, regardless of the inverter brand. We check compatibility before specifying a battery and will advise if a different integration approach is needed.

Both are excellent products. The Tesla Powerwall 3 is a premium all-in-one solution with a strong brand and excellent app — it is slightly more expensive. GivEnergy offers very competitive pricing, a modular capacity range, and excellent integration with solar systems. We install and support both and will recommend the right product for your specific situation.
