sun2wheel provides intelligent charging systems for electric vehicles that support bidirectional charging (Vehicle-to-Home and Vehicle-to-Grid). These systems, controllable via a dedicated app, enable electric vehicles to store surplus solar power from photovoltaic systems and supply electricity to buildings or the grid, significantly increasing self-consumption of renewable energy.

Problem
Electric vehicle owners often struggle to maximize the use of renewable energy sources like solar power due to the limitations of conventional charging systems. Traditional charging methods lack the ability to store surplus solar energy and redistribute it to homes or back to the grid, leading to inefficient energy consumption and increased reliance on non-renewable sources.
Solution
sun2wheel provides intelligent bidirectional charging solutions that enable electric vehicles to act as mobile energy storage units. Their systems allow users to store excess solar power generated by photovoltaic systems in their EV batteries and then supply this energy to power their homes (V2H), buildings (V2B), or even feed it back into the grid (V2G). This capability significantly increases the self-consumption of renewable energy, reduces electricity costs, and supports grid stabilization. The sun2wheel ecosystem includes a V2X-controller for centralized management of charging stations and batteries, along with a user-friendly app for convenient control and monitoring.
Target Audience
sun2wheel's primary customers include private EV owners looking to optimize their solar energy usage, as well as businesses, multi-dwelling units, and fleet operators seeking to implement intelligent charging and energy management solutions.
