Making solar energy directly usable
The LiON Box Sun combines an existing PV module with battery storage and direct charging technology in a compact system.
The solar energy generated is stored in the LiON Box Sun and made available via the LiON Splitter directly for charging e-bikes or e-scooters. A mains connection is not required for operation.
Note: The solar panel, shelter and bicycles are not included in the scope of delivery.
Modular design, expandable to two charging points
No second PV module is required to expand the system to two direct charging points. The LiON Box Sun captures the solar energy and transmits it via the connecting cable to the LiON Box Sun Sub.
A suitable PV module is connected directly to the LiON Box Sun. The PV module is not included in the scope of delivery.
The LiON Box Sun collects the energy generated and stores it in the built-in battery storage system.
The LiON Box Sun Sub is connected directly to the LiON Box Sun using the supplied connection cable.
The LiON Box Sun Sub adds a further battery storage unit and a second direct charging point to the system.
The LiON Box Sun handles power distribution within the system. This allows an existing PV module to be used for up to two direct charging points.
No second PV module requiredLiON Box Sun and Sun Sub
The LiON Box Sun forms the basis of the system. For a second direct charging point, it is supplemented by the LiON Box Sun Sub. Both units have their own battery storage and are powered by solar energy via a shared PV module.
Solar charging station
The self-sufficient base station combines a suitable PV module with battery storage and direct charging technology. It provides a direct charging point and forms the basis for the optional expansion with the LiON Box Sun Sub.
Expand modularly
The LiON Box Sun Sub expands the base station with a second battery storage unit and an additional direct charging point. It is connected to the LiON Box Sun via the connection cable and does not require its own PV connection.
The system principle
One PV module. Two battery storage units. Up to two direct charging points.
The LiON Box Sun handles the connection to the PV module. The LiON Box Sun Sub is connected via the connection cable.
Direct-load technology
With ONgineer’s direct-charging technology, e-bikes or e-scooters are connected directly to the LiON Splitter. The LiON Box Sun is configured with the appropriate Splitter variant for the battery systems used on site – without the need for a separate power supply unit or additional charging cable on site.
Select the correct plug on the LiON splitter.
Connect the selected plug directly to the e-bike or e-scooter.
Charging begins once the device is connected and is powered by the energy available in the battery storage system via the LiON Box Sun.
Rethinking existing sites
The LiON Box Sun is particularly suitable for sites where canopies or suitable mounting surfaces for PV modules are already in place.
Instead of installing a completely new solar system, the LiON Box Sun is integrated into an existing site infrastructure. A suitable PV module serves as the energy source, whilst battery storage and direct charging technology are compactly combined within the charging station.
Supplement existing canopies at businesses, public facilities or transport hubs with self-sufficient direct charging facilities.
Make use of suitable roof and mounting surfaces for a PV module and a compact direct charging point.
Supplement existing parking areas with a self-sufficient charging facility without having to install a whole new solar system.
The location is crucial: The PV module, orientation, shading and charging requirements must be designed to suit the specific application.
Technical specifications
The LiON Box Sun combines a PV connection, battery storage, safety features and direct charging technology in a robust housing. The LiON Box Sun Sub adds a further storage unit and direct charging point to the system.
ONgineer’s direct-charging technology supports battery systems from leading manufacturers such as Bosch, Shimano, Yamaha, Brose and BMZ.
The LiON Box Sun and LiON Box Sun Sub each feature an integrated battery pack with a rated capacity of 384 Wh.
The LiON Box Sun provides a direct charging point. With the LiON Box Sun Sub, a second charging point is added.
The LiON splitter, which features Bosch smart, Bosch oval and Rosenberger connectors, allows around 75 %* units from the most common e-bike battery systems in Germany, Austria and Switzerland to be charged directly at a single charging point.
The housing is protected against dust and water jets and has a high impact resistance.
Protection against overcharging, undercharging, overcurrent, short circuits and overheating ensures reliable operation.
Note: The specific Splitter configuration is selected to match the battery systems used at the site. Brand names mentioned are for reference purposes only and are the property of their respective rights holders. * Estimate based on market analyses of e-bike motor market shares (including Bosch ≈ 70% in Germany) as well as manufacturer and system specifications for Bosch smart/oval and Rosenberger connectors for Brose/BMZ, Specialized and selected Shimano systems in the DACH region (as of 2026).
Technical Specifications
