EMMA holds all SmartDongle functionalities for the commissioning and monitoring of a system, and takes the place of a meter too. This product can be connected to Shelly products for home automation, heat pumps, an external relay, and up to two SmartChargers.
Manageable devices
- Up to three inverters via RS485
- Two SmartChargers Huawei AC
- Two SG-Ready heat pumps
- Up to twenty Shelly devices
EMMA offers a wide range of functionalities to optimize energy management from a PV system, interacting with all electrical appliances and smart devices in your home.
- Electrical appliances: EMMA can be connected to several energy loads and, thanks to the Fusionsolar app, it is possible to schedule a timetable to maximize the use of green energy.
- TOU (time of use) mode or PV Preferred : EMMA can be set up in two different modes, “Time of Use” based on energy cost rates or “PV preferred” to favour the consumption of energy produced by the PV system.
- Power absorption monitoring: EMMA allows visualization of the power absorption of all appliances controlled via smart switches or plugs (Shelly devices). Data from connected devices is then available in the FusionSolar app.
Charging priorities
Through the Fusionsolar app, it is always possible to have an overview of all energy flows connected to EMMA. Thanks to the intelligence of this device, it is also possible to set different prioritites between all the energy loads connected, such as heat pumps and smart charging systems. In case of energy overloads, EMMA will automatically turn off less demanding devices to ensure a stable power supply.
