System component for multiple LiON Box X and LiON Box S units in self-sufficient solar operation
Solar power supply for e-bike charging points
Making solar energy available for multiple charging points
The LiON Switch connects compatible PV modules to a battery storage system and the LiON Box X or LiON Box S to form a centralised solar power supply.
The solar energy generated is stored in the LiON Switch and supplied as a 230 V power supply to the connected LiON Boxes. This creates up to four direct charging points, even at locations without a suitable mains connection.
Direct connection of suitable PV modules
Centralised supply of 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 mainly in terms of their distribution on site.
All in one compact package
4 direct charging points at 2 charging stations
Each LiON Box X provides two direct charging points. This configuration is particularly suitable when several charging points are to be grouped together in a compact arrangement at a central cycle 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 most 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 routing, the spatial distribution of the cycle parking spaces and the expected charging demand. ONgineer helps you assess these factors and plans the appropriate system configuration for your site.
The following points are particularly important for the initial classification:

LiON Switch in practical use
In collaboration with AlKuTec Bovend and Elektro Huber, ONgineer installed a PV-powered e-bike charging station for the Michelin tyre factory in Bad Fallingbostel.
LiON Switch units handle the central storage, control and power supply for the connected charging stations. This has made it possible to install several charging points independently of the public electricity 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.
FAQ
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 suitable 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. Provided the PV system is correctly designed, the LiON Switch can be operated independently of the mains electricity supply.
No. PV modules, the mounting structure and other site-specific components are designed to suit the specific project.
The LiON Switch features a robust housing with an IP65 and IK09 rating. It should nevertheless be installed indoors or in a sheltered outdoor area.
The electrical connection and commissioning must only be carried out by a qualified electrician.
Yes. Remote monitoring of selected plant parameters can be arranged on a project-by-project basis.
Are you planning to install several e-bike charging points at a single location without a suitable mains connection? Please send us the key details regarding the PV area, the desired number of charging points and their spatial distribution. We’ll work with you to assess whether a configuration comprising two LiON Box X units or four LiON Box S units is suitable for your project and to determine the most appropriate setup.
