Energy Management and Control

The SmartAssistant SA4H-A02 manages a household’s power generation and consumption in real time, enabling seamless communication between connected devices and the smart PV energy system. Using an algorithm, it predicts excess PV power and reserves corresponding storage capacity in the ESS to buffer solar surplus in the battery storage, preventing solar energy losses. This increases system yield by an average of 10% through the synergy of PV and ESS. For appliance scheduling, the device supports TOU mode or PV priority mode, allowing users to align consumption with tariff or yield profiles.

Device Connection and Load Management

Via the FusionSolar app, the SmartAssistant connects a wide range of household appliances, granting active consumers such as SG-Ready heat pumps and smart chargers higher charging or usage priority. In the event of overload, the device switches off less time-sensitive appliances to ensure a stable household power supply. The power consumption of devices controlled via smart switches or smart sockets is displayed individually.

Monitoring and Operation

All energy flows can be viewed at the module level via the FusionSolar app, providing transparent tracking of generation, storage, and consumption. The system’s operating status can be monitored or adjusted anytime and from anywhere, enabling continuous control of the energy balance even when away from home.
