Description

Huawei SmartAssistant SA4H-A02 is the ultimate control center for your smart home. It connects your photovoltaic system, battery storage, wallbox, and compatible smart home devices into a seamless ecosystem. Through automated control, you maximize your self-consumption and sustainably reduce your electricity costs – without any additional effort.

Your Benefits at a Glance

Maximum independence: Automatically prioritizes the use of self-generated solar power for your most important consumers.
Pure cost optimization: Benefit from dynamic electricity tariffs, as the system stops grid feed-in during negative prices or charges the battery cheaply from the grid.
Future-proof compatibility: Effortlessly integrates SG-Ready heat pumps, smart plugs (such as Shelly), and charging stations for electric vehicles.
Easy control: Seamless monitoring and control of all energy flows conveniently via the corresponding app.

Comprehensive Energy Management Made Easy

The Huawei SmartAssistant acts as the brain of your home system. It continuously analyzes energy generation and consumption to intelligently smooth peak loads (peak shaving). This way, you avoid costly load peaks and use your resources more efficiently. Whether it's charging the electric car exactly when the sun is shining or preheating water with surplus solar energy – the system decides proactively. Thanks to support for third-party integrations and VPP (Virtual Power Plants), you are also perfectly equipped for the energy market of the future.
