Every time demand peaks, your site risks going dark.
Stay under your limit. Stay open.
Battery power that adds capacity at peak, so busy sites stay within their supply and never trip.
The problem
Your busiest hour is your biggest risk
Kitchens, heat pumps and EV chargers keep adding load. The supply doesn't grow with them.
On-grid Motorway services, hospitality and retail
A fixed limit
Import capacity is fixed, often a few hundred amps, however busy.
Trips are costly
A breach can cut power for up to 4 hours, at around £10,000 a time.
The upgrade wall
A bigger connection can cost well over £1m and take years.
Load keeps growing
Electric heat and EV chargers push your peaks higher every year.
How it works
Extra power, exactly when you need it
MAX sits behind your meter and fills the gap between what you need and what the grid can give.
Watch
Allye software monitors your site load around the clock.
Boost
MAX adds power before demand reaches the limit, so no trips.
Recharge
It refills from the same supply in quieter hours, ready again.
Emergency planning
When the grid has to ration power
Governments plan for rota power cuts in a supply emergency. Protected sites such as hospitals are exempt. Most businesses are not.
Rota cuts planned under the Electricity Supply Emergency Code, revised April 2026.
The longest rota cut in France's plan, with the affected zones named the day before.
People on the Iberian Peninsula hit by the blackout of 28 April 2025.
Across the EU, every grid operator must keep a system defence plan that includes disconnecting demand. MAX keeps critical loads running through a cut, switching from grid to battery in under 40ms.

FAQ
Questions buyers ask
How does MAX stop my site tripping?
Allye software watches site load around the clock. MAX adds power before demand reaches the supply limit, then recharges from the same supply in quieter hours. At Roadchef it avoided 12 trips in year one.
Do I need to change my grid connection?
No. MAX works behind the meter on the supply you already have.
Can I add EV chargers without a bigger supply?
Yes. J&M Murdoch runs satellite DC fast chargers from MAX on a 32A supply, avoiding a £300k upgrade.
