Make your installation Smart and save energy with EMMA.

The EMMA is a device that manages energy in a home with a PV system. It can implement unified scheduling and management of home energy. The EMMA has two models:

• EMMA-A01: Only PV and ESS features are supported. Plant-level power control functions, such as maximum self-consumption and grid-tied point control, are supported for unified scheduling of home energy and plant-level energy optimization, further improving the PV energy utilization.
• EMMA-A02: Features of PV, ESSs, smart chargers, and smart loads are supported. In addition to unified scheduling of home energy, the EMMA-A02 can connect to smart loads such as chargers, SG Ready heat pumps, and smart switches. Users can set the reservation time to charge vehicles and heat water in advance at the specified time. In addition, users can set the priority to use PV energy for devices as required to make the best use of PV energy.

The EMMA device is also installed in the Huawei SmartGuards.
