5.1.2 Outdoor Requirements
The general requirements for selecting an outdoor ESS site are as follows:
● There must be no vegetation, especially ammable plants within 3 m of the
ESS or the site to protect the ESS from possible res. (Exemption: Single
specimens of trees, shrubbery, or cultivated ground cover such as green grass,
ivy, succulents, or similar plants used as ground covers shall be permitted to
be exempt provided that they do not form a means of readily transmitting
re.)
● No obstacle shall be above the ESS. For example, the ESS must not be
installed under a parking shed and PV modules must not be installed on the
top of the ESS.
● The safety distances between the ESS and production buildings must comply
with local re protection regulations or standards.
– The ESS located outdoors must be at least 10 ft (3.048 m) away from lot
lines, public ways, buildings, combustible materials, hazardous materials,
high-piled stock, parking spaces, and other exposure hazards not
associated with electrical grid infrastructure.
– If either of the following conditions is met, the distance between the ESS
and the production building shall be permitted to be reduced to 3 ft
(0.914 m). In addition, clearance requirements for equipment
transportation, installation, and maintenance shall be considered.
▪
There are 1-hour freestanding re walls, extending 5 ft (1.5 m)
above and extending 5 ft (1.5 m) beyond the physical boundary of
the ESS installation.
▪
Non-combustible exterior walls with no openings or combustible
overhangs are provided on the walls adjacent to the ESS and the re
resistance rating of the exterior walls complies with 2-hour re
resistance rating of ASTM E119 or UL 263.
● The distance between the exhaust device of an ESS and the heating and
ventilation vents, air intake vents of air conditioners, windows, doors,
unloading platforms, and re sources of other buildings or facilities must be
greater than 4.6 m.
● The ESS cannot be installed in salt-aected or polluted areas because this will
cause corrosion. The ESS can be used in the following or better environments:
– Outdoor environment more than 2000 m away from the coast. You are
advised not to use the ESS in an area 500 m to 2000 m away from the
coast. (If you need to use it, conrm with the vendor or the Company's
engineers.) If the site is less than 500 m away from the coast, outdoor
deployment is not allowed. Install the ESS indoors according to 5.1.3
Indoor Requirements.
– More than 1500–3000 m away from heavy pollution sources such as
smelteries, coal mines, and thermal power plants
– More than 1000–2000 m away from medium pollution sources such as
chemical, rubber, and electroplating industries
– More than 500–1000 m away from light pollution sources such as
packing houses, tanneries, boiler rooms, slaughterhouses, landll sites,
and sewage treatment plants
