Implementation of intelligent energy monitoring for the entire home in the STREAM system
Household appliances such as lamps and permanently installed kitchen appliances cannot be monitored with plug-and-play smart plugs. In this case, a smart meter is required to monitor electricity consumption throughout the household and enable the system to automatically create schedules.
Can be combined with STREAM AC Pro for energy storage in the PV system
Thanks to its AC-coupling design, the STREAM AC Pro can be easily integrated into existing solar systems, enabling plug-and-play energy storage. By adding a smart meter, the system can determine when to charge and when to use AC Pro to power the household, maximizing the use of solar energy.
Easy to install
Only simple installation and connection is required, with no high installation costs or the need for circuit modifications.
