AC Wallboxes, 7-22 kW
Wall-mounted AC chargers for homes, workplaces, hotels and fleet depots — compact, OCPP-ready and built to scale across thousands of sites.
Right-sized power for long dwell
Most vehicles sit parked for hours. AC charging delivers a full battery during that dwell at a fraction of DC hardware cost — the highest-margin line for distributors and property owners.
- Full charge overnight on a standard 7.4 kW circuit
- Three-phase 11/22 kW cuts session time for workplaces
- IP65 enclosure rated for indoor and outdoor mounting
- OCPP-native so every unit joins any backend

Four requirements to go live
A straightforward install — most electricians finish a single unit in under two hours with the supplied bracket and pre-wired board.

Wall & Pole Mounting
The IP65 enclosure mounts to any flat wall or pole with the included bracket, indoors or outdoors.
Network Access
Wi-Fi or 4G coverage at the site for OCPP connectivity; Ethernet is available for fleet depots.
Compliance & Permits
Full CE/UKCA technical file and wiring diagram ship with each unit to speed local inspection and sign-off.
