4.4.1 Choosing the installation site
The cabinet hosting the energy storage system is
IP20 and suitable for installation in dry, dust-free
environments. According to EMC standards, the system
is designed to meet the installation requirements in a
home environment.
Select the installation site according to the following
requirements:
• The installation site should be well ventilated and
sheltered from direct sunlight, rain and snow;
• The building is designed to withstand earthquakes
• The location should not be in proximity of the sea,
to avoid salt water and humidity.
• Ensure there are no corrosive gases at the
installation site, including ammonia and acid vapor.
• Ensure there are no flammable or explosive
materials at the installation site or nearby.
• The floor of the installation site must be dry and
flat. Under no circumstance there should be water
on the ground in proximity of the energy storage
system. Ensure that the ground level is levelled and
can fully carry the weight of the energy storage
system.
• The installation site should be clean.
• Ensure enough clear space between the front,
rear, left and right, top and wall of the energy
storage system to ensure good ventilation and heat
dissipation, and to provide space for installation,
maintenance, and safe escape.
• The ambient temperature of the installation site
should range between -10 °C and 40 °C; the relative
temperature should range between 4% to 100 %.
Note: If the ambient temperature is outside of
the operating range, the battery pack will go in
self-protection mode and stop operating. The
optimal temperature range for the battery pack to
operate is between 15°C and 30°C degrees. Frequent
exposure to harsh temperatures may deteriorate the
performance and lifetime of the battery pack. For this
reason, it is recommended that temperature and
humidity stay at a constant level.
