The money page

Most sites never see the market they are buying from.

Flat-rate contracts feel safe, but you pay a premium every hour, all year.

More power, starting now

Bigger incoming supplies are our home turf: we deliver grid upgrades in partnership with UK Power Connections Ltd, a NERS-accredited ICP, so the work isn't left at the back of someone else's queue.

Even a well-run upgrade takes time to consent and construct, and ambitions rarely wait. The battery closes that gap: discharging alongside the grid at busy times, it lets the site draw more power at peak from day one. Once the new connection is energised, the pair work harder together.

West Court Retreat banks £54–63k a year

A coordinated energy centre runs this Home Counties hotel and spa through peaks and outages alike — banking £54–63k a year in savings and grid revenue.

The car park starts earning its keep

Pumps are out. Plugs are in.

A hotel car park is the perfect charging forecourt: cars sit for hours, drivers pay for convenience, and demand arrives on its own four wheels. What usually stalls the plan is capacity.

The battery solves both halves. It creates the headroom to add more bays, and fills them with energy bought in the cheap half-hours or made on site — sold on at forecourt rates. Every unit sold shortens the payback on the entire system.

Inside the factory

Built on the Blade cell.

Every system we install is built on BYD's Blade cell — lithium iron phosphate chemistry produced on fully automated lines to automotive standards.

It's the same cell that passes the nail-penetration test without fire or thermal runaway — the safety standard we hold from a single node to a utility bank.

BYD MC Cube

The world's first BESS with the Blade Battery.

BYD's own film on the MC Cube — the first energy storage system to integrate the Blade cell, and the platform behind the utility-scale banks we install.

Why we standardise on the Blade cell

Lithium iron phosphate
{{ s.value }}
{{ s.label }}

The Blade cell passes the nail-penetration test — the industry's harshest abuse trial — without fire or thermal runaway. It is the reason we are comfortable placing storage inside buildings full of guests, patients and equipment. See the manufacturing and nail-penetration films below.

Engineered not to burn.

See the Blade Battery made

The nail-penetration test, on film

A steel nail driven straight through a live cell — the most rigorous thermal-runaway trial in the industry. Conventional lithium-ion cells reach hundreds of degrees and catch fire; the Blade cell stays cool enough to touch.

Watch it happen — this is why we specify LFP for buildings full of guests.

Victron Energy

Energy. Anytime. Anywhere.

Designed in the Netherlands. Trusted worldwide.

In the early 70s, our founder, Reinout Vader, took apart a dodgy, borrowed inverter and asked himself how he could improve it. His solution started Victron, now one of the world's foremost developers of power products for marine, RV, off-grid, industrial, and speciality vehicle use.

Engineered to outlast extremes, our open, modular systems provide the freedom to customise and control your energy supply without limits or lock-in. That's why millions of users worldwide trust us to keep things running, no matter where they are or what they do.

Victron Energy · Hybrid power · UPS & genset

The hybrid generator revolution.

Victron inverter/chargers, lithium batteries and the VRM monitoring platform turn a generator into a hybrid system — cutting fuel, emissions, noise and service intervals by as much as 80%, while delivering uninterrupted clean power on or off grid.

For smaller sites up to 2 MW, three-phase, Victron is the intelligent core that runs the load and holds the supply the instant the grid drops.

Victron MultiPlus 20kW

The heart of the Always Energy node.

One inverter is one node. Each MultiPlus supplies 240 volts at 100 amps, single phase — the core that runs the load and holds the supply, paralleled up as the site grows.

The Largest Off Grid Victron install in the UK.

This timber yard in England has changed from running huge diesel generators all day every day to a huge lithium and Victron Energy system. Using a combination of solar and generator the owner has significantly reduced his costs, and the system has kept up with the large power requirements of the machines as well as the house.
