Refuel with solar power

06:30

It is early morning and your employees’ commercial and service vehicles are fully charged and ready to go.

10:00

While your employees are out on the job, the PV system charges the battery-storage systems with solar power.

13:30

During the day, your employees and customers can charge their electric vehicles if they need to. The power comes directly from the roof or the battery-storage systems.

17:00

Late in the afternoon, your employees gradually return and the vehicles have to be charged. Since the sun is still shining, this can initially be done using solar power directly from the roof.

20:30

If the battery-storage systems are empty, the electric vehicles are charged with power from the utility grid.

SMA Data Manager M monitors and analyses the entire system. Via SMA Sunny Portal powered by ennexOS, it receives information about the weather and time-related power supply tariffs. On this basis, it creates a yield forecast.

On the basis of the yield forecast and analysis of your consumption, SMA Data Manager M controls the system so that free solar power – either directly from the roof or from the battery-storage systems – is prioritised for charging your electric vehicles. If the forecast shows that additional charging power is required from the grid, the charging of controllable loads such as service and commercial vehicles that are not currently required is shifted to periods when your power supplier’s tariffs are affordable, wherever possible.
