Basic Solution for Intelligent Energy Management

Using the intelligent load control, the Sunny Home Manager uses its control options to shift the operation of flexible loads to times with high PV generation.

Daily profile of a PV system, consumption and self-consumption – without load control (example)

The red frame in this example shows a load peak in the evening. This load peak, for example, is caused by a washing machine that is switched on manually in the evening.

Daily profile of a PV system, consumption and self-consumption – with load control (example)

The red frame in this example shows the shifting of the load peak to the afternoon. Due to the automatic control by the energy management system, operation of the washing machine is shifted to a time period in which cheaper PV energy is available. PV self-consumption increases, lowering the energy costs for the user.

The Sunny Home Manager forms the core of the SMA basic solution for intelligent energy management.

PV system with Sunny Home Manager (example)

The Sunny Home Manager offers the following energy management functions:

• Visualization of PV system data in Sunny Portal ( > Visualization of PV System Data in Sunny Portal)

• Intelligent load control ( > Load Control)

• Dynamic active power limitation ( > Dynamic Limitation of Active Power Feed-In to Avoid Derating Losses)

• Zero Export ( > Limitation of Active Power Feed-In to 0% or 0 W)

• Access to grid management services via Modbus interface, e.g. for active power limitation by the grid operator
