Huawei EMMA-A02 Energy Management Assistant

The Huawei EMMA, energy management assistant, is an optimised power solution which integrates metering, communication, and management. It reads real-time energy generation and consumption while communicating between appliances and smart PV energy system.

The EMMA-A02 device supports PV, ESSs, smart chargers, and smart loads. In addition to unified scheduling of home energy, it can connect to smart loads such as chargers, SG Ready heat pumps, and smart switches.

Customers can set the reservation time to charge vehicles and heat water in advance at the specified time. In addition, customers can set usage priority for devices as required to make the best use of PV energy.  With a power limit on feed-in to the grid, EMMA can forecast and manage energy surplus from a battery system averting solar energy loss.
