2.4 Introduction to Typical Networking
⚫The SigenStor Home energy storage system consists of photovoltaic panels,
inverters, battery packs, master control switches, loads, power grids, etc.
⚫The main function of SigenStor Home energy storage system is to store the
direct current generated by photovoltaic panels into battery packs. Or
alternatively, the electricity in the photovoltaic system and the battery pack
can be converted into alternating current for use by the load or incorporated
into the grid.

⚫When B is SigenStor AC, A is not configured.
⚫In case of home-wide backup, F2, G2, and H are not configured; for partial
backup, H can be left un-configured; in case of partial backup +
zero-power grid connection control, F2, G2, and H are configured.
⚫As a backup energy source for long-term off-grid applications, the diesel
generator can work in tandem with the Gateway to provide a smooth
transition between PV, storage and diesel power generation.
⚫It is recommended to use FE and WLAN for communication with inverter.
CommMod users must top up their own 4G data plan after a period of 2
years.

recommended to install in a sheltered location. If the area is susceptible
to natural disasters such as floods, landslides, earthquakes, or typhoons,
take preventive measures during equipment installation.
⚫Do not install the equipment in environments with electromagnetic
interference.
⚫Ensure that the temperature and humidity of the installation environment
comply with the equipment's requirements.
Installation Position Requirements
⚫Do not tilt or overturn the equipment to ensure that it is installed
horizontally.
⚫Do not install the equipment in a place where children can easily reach it.
⚫Do not install the equipment in areas subject to fire or moisture (including
but not limited to kitchen, tea room, toilet, shower room, laundry room,
etc.).
⚫Please keep away from daily working and living areas (including but not
limited to living room, bedroom, studio, lounge, study, etc.).

(including but not limited to attic, basement, etc.).

19 / 33
User Manual
⚫Do not install the equipment in mobile scenarios such as
RVS, cruise ships, and trains.
⚫You are advised to install the equipment in a position that is easy to
operate, maintain, and view indicator status.
⚫When installing the equipment in the garage, do not install the equipment
in the position where the vehicle passes through to avoid collision.
Mounting Surface Requirements
⚫Do not install the equipment on a flammable carrier.
⚫The installation carrier must meet load-bearing requirements. Solid
brick-concrete structure, concrete walls, and ground are recommended.
⚫The surface of the installation carrier must be smooth and the installation
area must meet the installation space requirements.

User Manual
⚫The maximum operating temperature range applicable to the equipment is
-20°C to 55°C, and the recommended optimal operating temperature range
is 10°C < T < 35°C.
⚫When the battery pack temperature is below 0°C, immediate charging is not
possible, and the battery pack (the built-in heating module can be
automatically enabled) will activate the heating feature automatically. The
best charging performance of the battery can be achieved after heating for
less than 2 h. The heating feature will consume power.
⚫At a temperature > 40°C, the operation of the equipment may trigger a
power derating that prevents the equipment from operating optimally. The
higher the temperature, the shorter the service life of the equipment.
