User centric approach
DESIGNED WITH
EV USERS IN MIND
EASY TO NAVIGATE TOUCH DISPLAY BUILDS CONFIDENCE AT A GLANCE
The user interface with support for multiple languages, is easy to use and provides all the necessary information for first-time and advanced users alike.




CONTACTLESS PAYMENT
MADE SIMPLE
Contactless payment module allows faster ad-hoc use without registration, thus enhancing user convenience. In a cluster of chargers, the master station can serve as a payment terminal for the whole group, further reducing operational costs of charging infrastructure.
Future proof
DESIGNED FOR
SCALABILITY
STREET FURNITURE FORM. BIG ON ROBUSTNESS, SMALL ON FOOTPRINT
Compact design facilitates installation in locations with limited available space. Distinct design with a steep slope at the top makes sure the stations are easily recogniseble and they stay clean. It is made of robust stainless steel for outstanding durability in all weather conditions.




CUSTOMIZATION HELPS YOUR CHARGING NETWORK TO STAND OUT
Flat surface offers valuable possibilities for branding and customization, to make sure your charging network stands out. With its distinct shape, INCH Duo charging station is easily spotted while remaining unobtrusive in public locations.


OPERATING MULTIPLE CHARGING STATIONS?
With interactive charging, the power among them will be distributed evenly. Clustering capabilities out-of-the-box ensure the scalability of charging infrastructure on location. Cluster power management algorithms support mixed autonomous groups of Etrel charging units. Power management capabilities can be further extended with Load Guard to balance the available charging power between chargers, based on connected vehicles, priorities and required amounts of energy without overloading the installation.


Return on investment
DESIGNED TO
SUPPORT YOUR BUSINESS
EASY INSTALLATION
AND MAINTENANCE
INCH Duo charging station is designed with all users in mind. The station service area is comfortably accessed through wide-opening service door, where click-in component modules ensure faster field maintenance. Added tilt and door status sensors allow instant information in case of the traffic accident or vandalism, helping you increase infrastructure safety and maintain your network in great shape.




WEB INTERFACE ENABLES REMOTE TROUBLESHOOTING FOR MINIMUM MAINTENANCE COST
Monitor and manage charging through the advanced web interface either from a phone or computer. The web app works on any device in the same network and gives the user an in-depth insight into charging energy consumption.
UNLOCK FULL POTENTIAL WITH OCEAN BACK END SYSTEM
Connecting charging stations in charging management system open up new possibilities for management and monetisation of charging infrastructure, remote maintenance and support for users. Offer users a seamless transition between charging locations with a single app, while keep track of all your charging equipment out in the field.
