Technology / Convert once
DC bus explained
Convert once. Lose less. Grow without starting again.
Batteries, solar panels and electric vehicles all run on DC. Conventional sites keep converting energy back and forth through AC. GridUnlock converts it once, at source, and shares it across the site on a DC bus.
Conventional
AC-centric site
Energy can be converted three times before it reaches the vehicle, losing some at every step. Every new charger needs more AC capacity.
GridUnlock
DC-centric site
One conversion at source. Battery, solar and chargers share DC energy directly, and the battery tops up capacity when the grid can't.
Why it matters for your site
Up to 22.7%
fewer conversion losses, so more of every kWh you pay for reaches the vehicle.
More from less
The battery covers peaks, so you charge more vehicles on the same connection.
30kW → 5MW+
Add chargers, storage or solar to the bus without rework.
Modules, not boxes
Because DC is the root of the technology, upgrades mean swapping modules rather than replacing whole units.
