Built for First Time Right
The installation works the first time: tested hardware, front-facing terminals, and commissioning from the Plugchoice app in under three minutes.
Products that work
Every charger leaves the factory tested, and every firmware update is validated before rollout.
Fewer callbacks
When installations work the first time, you're not driving back to fix someone else's problem.
Support when you need it
When you do call, you reach someone technical, usually within five minutes.
Which charger fits which project
Every model runs on Plugchoice and speaks OCPP, so the choice comes down to metering, connections and how it installs. Here is the whole range side by side.

Integrated RCBO, daisy-chained power
Two Pro builds the RCBO into the charger, so the panel needs no separate RCD plus MCB: less to wire, less panel space, faster sign-off. And because protection lives in the unit, chargers chain on a single circuit: pull one cable run and feed through from charger to charger.
- No external RCBO. Saves 150-300 euro in panel hardware and wiring per charger.
- 40% less cabling. Feed through one charger to the next instead of home-running every unit.
- 2x 40A RCBOs built in. 44kW in, 2x 22kW out on the Two Pro, ready to chain out of the box.
- The customer resets it themselves. A trip is a ten-second fix at the side panel: no tools, no opening the charger, no van.
Sealed click-in install
On One Business and Two Pro, all wiring lands in the backplate. Mount the plate, land the conductors, then the charger clicks over the top, sealed.
- 15 minutes faster per unit. Every connection is accessible before the charger goes on the wall.
- Sealed from the factory. The unit stays closed on site, rated IP65 on the One Business.
- Swaps without rewiring. The feed stays on the plate; a service swap is click off, click on.
Power management over a wireless meter
Load balancing, solar integration and power sharing, all configured in Plugchoice. Works with common energy meters.
Metering setups
These four are examples, not the whole list. Power management works with categories of meters: Modbus kWh meters, P1, HAN and Linky smart-meter ports, and CT clamps. Supported models per type are listed in Plugchoice.

Questions from installers
Can I daisy-chain multiple chargers?
Yes, safely with built-in RCBOs. The Two Pro includes internal RCBOs (residual current breakers with overcurrent protection), which allows safe daisy-chaining on a single circuit without additional protection in the distribution panel.
Reduced panel space. No need for separate RCDs or MCBs per charger. This significantly reduces distribution board requirements and speeds up installation.
Is the RCBO easily resettable?
Two Pro: side compartments. Two Pro features dedicated side compartments for each RCBO. Easy access for quick resets without opening the main unit.
Is your load balancing safe?
Zero fuse incidents. We've deployed dynamic load balancing across thousands of installations without a single fuse blow. Power is throttled back fast enough to keep the main fuse safe.
Sub-second response over Modbus. For installations that need it, connect the energy meter over MODBUS. Response times drop to sub-second. Smart charging details
How fast is your technical support?
Partners get priority. Registered partners and installers usually get a human response within 5 minutes during business hours, from an engineer who knows the hardware.
Multiple channels. Reach us via phone, WhatsApp, or email. We speak Dutch, English, and German. Become a partner
Do you offer on-location service?
Yes, in the Netherlands. For partner installations in the Netherlands, we offer on-location service when remote troubleshooting isn't enough. We'll come to the site and resolve the issue directly.
Remote diagnostics first. Most issues are diagnosed and resolved remotely via the web portal; we dispatch only when remote access is not enough. Web portal features
