Specifications
Product description
The Huawei EMMA-A02 Energy Manager is an intelligent control and optimization system for solar installations with inverters, batteries, electric vehicle chargers, and home automation devices. Thanks to its prediction capability, learning algorithms, and multiple communication interfaces, it allows prioritization of renewable energy use, reduction of feed-in, and automation of loads in homes or small businesses. It integrates advanced functions such as energy balancing, scheduling, and compatibility with Shelly, EV, and heat pumps.
Main features
- Direct three-phase energy measurement up to 63 A, expandable with 50 mA CT.
- Comprehensive connectivity: RS485 × 2, LAN, WAN, and 2.4 GHz WiFi (AP + client mode).
- Full compatibility with Shelly (up to 20 devices), inverters, and Huawei EV.
- Intelligent prediction algorithms to maximize self-consumption.
- Digital load control and integrated energy automation.
- DIN rail mounting, compact dimensions, and very low consumption (4 W).
Advantages or benefits
- Reduces the electricity bill by maximizing the use of produced solar energy.
- Allows automation of appliance or heat pump usage based on solar surplus.
- Enables smart EV charging during solar hours or off-peak rates.
- Compatible with remote control via FusionSolar and direct local connection.
- Ideal for smart homes with Shelly devices (plugs, relays, sensors).
Purpose or applications
