2.1 Intended Use
The SunnyHomeManager is the central product responsible for energy management in households with a
photovoltaics (PV) system and battery-storage system for self-consumption. The SunnyHomeManager continuously
records the solar power generated by the PV system and, if desired, ensures optimal use of the solar power by
combining all suitable energy flows in the household to create an intelligent system and, upon request, control it
automatically.
The online portal Sunny Portal is used to operate and configure the SunnyHomeManager. The user can make all the
required and desired settings here.
The SunnyHomeManager is not an energy meter for power consumption in the sense of the EU directive 2004/22/
EG (MID). The SunnyHomeManager may not be used for billing purposes. The data collected by the
SunnyHomeManager relating to the power generated by your PV system may deviate from the data of the main
energy meter, which is used for billing purposes.
The SunnyHomeManager supports up to 24 devices and can actively control a maximum of 12 devices.
The SunnyHomeManager is not suitable for controlling life-sustaining medical devices. A power outage must not lead
to personal injury. Loads connected to the SunnyHomeManager must have an CE, UKCA, RCM or UL identification
label.
The SunnyHomeManager is approved for use in all EU member states, in Great Britain, Australia and selected other
countries.
The type label must remain permanently attached to the product.
Environment
The product is designed for indoor use only.
The SunnyHomeManager may only be connected to the subdistribution of the household on the load side behind the
energymeter of the electric utility company. The SunnyHomeManager must be installed in a switch cabinet or in a
domestic installation cabinet in the area of the additional applications intended for this as per VDE-AR-N
4100:2019-04.
It is possible to use the SunnyHomeManager in delta IT grids. When using the SunnyHomeManager in delta IT
grids, the cumulative power values are correctly measured. Due to the measuring principle of the
SunnyHomeManager, other measured values may be incorrect.
