HUAWEI EMMA-A02 Energy Management Assistant
It is an advanced energy management assistant that integrates measurement, communication and management. This system reads energy generation and consumption in real time, communicating with home appliances and the intelligent photovoltaic power system. The goal is to achieve intelligent energy management and optimize system deployment.

An optimized power solution
When there is excess power produced compared to the grid supply limit, EMMA executes a space reserve command in the ESS (Energy Storage System) based on an algorithm. In this way, the excess energy is stored in the ESS for later use, providing backup energy support and preventing solar energy loss.

Emma A02 PV Management System
Supported Devices:
– Up to three inverters via RS485
– Two Huawei AC chargers
– Two SG-Ready heat pumps
– Up to 20 Shelly devices

EMMA Access
Offers a wide range of features to optimize the use of photovoltaic energy.
Connecting home appliances
EMMA can be connected to various home appliances. It can be set to run at specific times via the FusionSolar app. This allows you to maximize the rate of green energy consumption.
TOU or preferred PV mode:
You can configure EMMA to follow the TOU (Time of Use) tariff mode or the preferred mode of PV energy use.
Energy consumption monitoring:
EMMA allows you to view the energy consumption of home appliances controlled by smart switches or sockets. Data from connected devices is available in the app.
Energy graph:
With EMMA, the energy landscape of your home is not just in your mind, but accessible via the app.

Unique management: Visibility on the go
The FusionSolar app provides detailed monitoring of all energy flows at the module level. Whether solar generation takes place above the roof or energy storage and consumption is below the roof, the app manages everything in a unique way. You can monitor or adjust the operating status of your system anytime, anywhere.
With sufficient solar energy, you can ensure charging priority for some of the active appliances, such as the SG (Smart Grid) ready heat pump and the smart charger. In the event of an overload, EMMA will switch off less demanding devices to ensure stable energy at home.
