You're paying peak rates for power your own roof already made.
Use your own power. Cut your bill.
Battery storage for commercial and industrial sites that stores your solar, cuts peak and capacity charges, and earns from the grid.
The problem
Your bill is set by your worst half hour
Most sites only hit their peak for a few hours a day, but pay for it all year.
On-grid Commercial and industrial sites
Peak charges
Red-band charges at peak times raise the cost of every unit used.
Capacity you don't use
Agreed capacity is charged every day, whether you need it or not.
Solar sold cheap
Surplus exported at around 7.5p and bought back at 26p at night.
The upgrade wall
A bigger connection can cost well over £1m and take years.
How it works
A battery that works every half hour
MAX sits on your site, on the connection you already have, and does three jobs at once.
Store
Charge from your surplus solar and cheap off-peak power.
Shave
Discharge at peaks to cut red-band and agreed capacity charges.
Earn
Sell flexibility to the grid through optimisers when idle.

Backup included
And it keeps the lights on
switchover from grid to battery in an outage, so tills, cold stores and IT keep running.
grid upgrade: more power from the connection you already have, with no new supply needed.
Why MAX
Made for working sites

FAQ
Questions buyers ask
How does a battery cut my electricity bill?
MAX stores surplus solar and cheap off-peak power, discharges at peak times to cut red-band and capacity charges, and earns from grid flexibility when the site doesn't need it. Modelled for a MAX300 on a London trading estate: £19,900 a year.
Do I need a bigger grid connection?
No. MAX works on the connection you already have and adds power at peak, so there is no new supply to pay for.
What data do you need to model my site?
A year of half-hourly meter data. We show the saving line by line before you commit.
