For Farms & Agricultural Buildings

Battery storage built for how a farm actually runs

Milking parlours, calving sheds, grain drying and refrigeration don't stop for a power cut. Storwell designs battery storage around the way a farm actually draws power — not a generic domestic install.

Reliable backup power

Keep milking parlours, calving sheds and refrigeration running through an outage, without depending on a diesel generator.

Manage your 3-phase demand

Reduce peak demand charges and make better use of your farm's own solar generation across the buildings that need it most.

Grant support available

Battery storage can qualify for TAMS grant support when installed alongside new solar PV — we'll help you understand what's currently available for your farm.

We're out meeting farmers at events like the National Ploughing Championships this year — get in touch if you'd like to talk battery storage for your farm.

Systems We Specialise In

Battery brands matched to your property — not a one-size-fits-all sale

Storwell specialises in the design, installation and support of Sigenergy, EcoFlow and Solis battery systems. We recommend whichever fits your property, budget and goals — not the same brand for every customer.

Sigenergy Premium

All-in-one battery, inverter and EV-charging ecosystem. A strong fit for premium homes and future-ready installations.

EcoFlow Modular

Stackable, modular battery units with excellent backup capability — a strong retrofit option for adding storage to an existing system.

Solis Value

Flexible hybrid inverter platform with broad battery compatibility — dependable performance at excellent value.

Not sure which is right for you? That's exactly what the Free Battery Opportunity Assessment is for.

Your solar is only doing half the job — without a battery.

Every kWh you don't store gets exported at low rates, then bought back at full price come evening. A battery — or an upgrade to one that's underperforming — turns that around, and there's never been a bigger window to act.

Battery Storage For Your Home

Already have solar? Already have a battery?

Either way, it's worth finding out whether your system is set up to give you what you're actually expecting from it.

Already have solar?

Storwell can assess whether adding battery storage makes sense and determine how the system could work alongside your existing setup.

Already have a battery?

Storwell can assess whether it is operating as effectively as it should — and what optimisation could recover.

★ Commercial Energy Storage

Commercial Energy Storage

As businesses increasingly generate, store and manage their own electricity, battery storage becomes more than backup power. Storwell brings the same rigorous, data-led approach used on every domestic job to commercial battery storage — peak shaving, load management, solar optimisation and energy arbitrage.

Powered By SES

The Storwell Energy System

Every Storwell system is assessed through SES — our methodology for understanding how an energy system should be designed, installed and operated. Not a piece of software you have to learn — a structured process behind every job we do.

The same process runs behind every job we take on — domestic or commercial.

How It Works

A structured process, start to finish

01

Assess

Understand existing electricity usage, solar, battery, tariff and future requirements.

02

Design

Determine the appropriate storage solution rather than simply selling the biggest battery.

03

Install

Professional installation and commissioning.

04

Optimise

Configure the system around how the property actually uses energy.

05

Monitor

Review performance over time to identify faults and opportunities.

Why Storwell

A different kind of battery company

Storage specialists

Not a company that happens to install batteries.

System-first approach

Look at the whole energy system rather than simply selling hardware.

SES methodology

A structured assessment, installation and optimisation process.

Built for what's next

Battery storage is moving toward smarter tariffs, flexible loads and increasingly sophisticated energy markets.

Free Battery Opportunity Assessment

A quick way to understand whether battery storage may be worth investigating — a couple of minutes, mobile-friendly, no obligation. This isn't a substitute for a full SES assessment, just a useful first indication.

What are you enquiring about?
Do you already have solar?
How much solar do you have?
Roughly is fine.
Do you already have a battery?
What size is your battery?
Roughly is fine.
Do you have an EV?
Do you have a heat pump?
What type of business or building is this for?
Roughly is fine.
What type of farm is this?
Which buildings or equipment need reliable power?
Optional — e.g. milking parlour, calving shed, grain drying.
Do you have a 3-phase electricity supply?
Do you currently rely on a diesel generator for backup power?
What's your approximate annual electricity usage?
Who is your electricity supplier?
Optional.
What type of tariff are you on?
What's your main objective?
County / location
Almost done — where should we send your result?
We'll call you within 1 business day to talk through it — no pressure, no obligation.
Strong Opportunity

This looks like a strong battery-storage opportunity. Based on the information provided, it may be worth assessing battery capacity, solar generation and tariff interaction in more detail.

This is an indicative first read, not a guaranteed saving or battery recommendation. We'll call you within 1 business day — a full SES assessment looks at your system in more detail from there.
