Manage and distribute solar energy

It is early in the morning in the industrial bakery, where the ovens have to be fired up. The PV system is not yet providing sufficient power. This means that a large amount of additional grid power has to be purchased. A peak demand is imminent – and that can become expensive.

The solution: SMA Commercial Energy Solutions provide visibility to when peak demand occurs so you can adjust your energy usage. In this instance,to stagger the times at which the ovens are started. Less power has to be purchased in one go and peak demand charges can be avoided.

Late in the morning, the PV system provides more solar power than is needed for operations. The surplus power is temporarily stored in the battery-storage systems for later use, rather than being fed into the grid.

It is the evening. Lots of appliances – cooling systems, ventilation, lights and so on – are in operation and another peak demand is imminent because the PV system is no longer providing sufficient power. But the battery-storage systems are fully charged and so can be used for powering the appliances. No power – or, at the very least, less power – has to be purchased. After all, it is still very expensive at this time.

Late in the evening, the battery-storage systems are empty and the PV system cannot generate solar power. But fortunately, the power tariffs are affordable – something that your SMA Energy System for Business took into account at the planning stage. This means that your appliances can procure low-cost power from the utility grid.

It monitors and analyses all energy flows in your company.

Sunny Portal powered by ennexOS supplies it with additional information such as a weather forecast and time-based electricity supply tariffs and, on this basis, creates a deployment schedule.

All energy flows are coordinated and controlled so that as much solar power as possible is consumed and expensive load peaks are avoided.
