6-Week Install
WattBox installed on a farm site, boosting available power with solar and battery storage

Poultry farm, Midlands

Hit their grid limit adding new ventilation and cold storage. Rather than wait months for a DNO upgrade, a WattBox boosted their available power in 6 weeks — and cut their energy bill at the same time.

HOW IT WORKS

WattBox runs in parallel. Your grid doesn't change.

WattBox sits between your grid supply and your heavy machinery. It charges from solar and cheap-rate grid power, then provides extra power on demand — boosting your total available draw beyond what the grid alone can deliver.

HOW IT WORKS

How WattBox boosts your power

1

Step 1

Solar charges your WattBox

Solar panels generate free electricity during the day. WattBox stores it in industrial batteries, building your power reserve.

2

Step 2

Batteries boost your supply

When your machinery draws more than the grid can deliver, WattBox supplies the difference instantly. No tripping, no brownouts.

3

Step 3

Peak demand? No problem.

Milking, cooling, ventilation all running at once? WattBox handles the load. Your grid supply stays within its limit while your farm runs at full capacity.

Step 4

Bills drop, not just power rises

You’re generating and storing your own energy, using less from the grid. The same system that boosts your power also cuts your bills.

More power today. Lower bills every day.
