System component for multiple LiON Box X and LiON Box S units in self-sufficient solar operation
Solar Power for E-Bike Charging Stations
Making Solar Energy Available for Multiple Charging Points
The LiON Switch connects compatible PV modules to battery storage and the LiON Box X or LiON Box S to form a centralized solar power supply.
The solar energy generated is stored in the LiON Switch and supplied as a 230-V power source to the connected LiON Boxes. This creates up to four direct charging points, even at locations without a suitable grid connection.
Direct connection of suitable PV modules
Central power supply for 2 × LiON Box X or 4 × LiON Box S
Integrated battery storage for up to 4 direct charging points
Two System Variants
The LiON Switch can power either two LiON Box X units or four LiON Box S units. Both configurations provide a total of four direct charging points and differ primarily in how they are distributed on-site.
Compactly bundled
4 direct charging points at 2 charging stations
Each LiON Box X provides two direct charging points. This configuration is particularly well-suited when multiple charging points need to be grouped together in a compact layout at a central bicycle parking area.
Flexibly distributed
4 direct charging points at 4 charging stations
Each LiON Box S provides a direct charging point. This allows the individual charging points within the site to be arranged and distributed more flexibly.
Which configuration is more suitable depends on the desired distribution of charging points, the cable routes, and the structural conditions at the site.
Project-Specific Design
Whether two LiON Box X units or four LiON Box S units are more suitable depends not solely on the desired number of charging points.
Other key factors include the available PV area, the cable routes, the spatial distribution of bicycle parking spaces, and the expected charging demand. ONgineer helps you assess these factors and plans the right system configuration for your location.
The following points are particularly important for the initial classification:

LiON Switch in Practical Use
ONgineer , in collaboration with AlKuTec Bovend and Elektro Huber, installed a PV-powered e-bike charging station for the Michelin tire plant in Bad Fallingbostel.
LiON Switch units handle the central storage, control, and power supply for the connected charging stations. This made it possible to implement multiple charging points independently of the public power grid.
Joint project with:
The reference project was implemented using an earlier generation of the LiON Box. Current projects are planned using the LiON Box X or LiON Box S.
Frequently Asked Questions
Answers regarding system configuration, PV integration, installation, and off-grid operation.
The LiON Switch is a central control, storage, and power supply unit for off-grid charging infrastructure. It connects compatible PV modules to the LiON Box X or LiON Box S.
The LiON Switch is designed for two LiON Box X units or four LiON Box S units. Both configurations allow for a total of up to four direct charging points.
No. If the PV system is properly designed, the LiON Switch can operate independently of the public power grid.
No. PV modules, mounting structures, and other site-specific components are designed to suit each individual project.
The LiON Switch features a rugged housing with an IP65 and IK09 rating. However, it should be installed indoors or in a protected outdoor area.
The electrical connection and commissioning may only be performed by a qualified electrician.
Yes. Remote monitoring of selected system parameters can be provided on a project-by-project basis.
