and operation of the LCD touch screen.
⚫If the machine is placed directly outdoors, it is recommended to take the necessary
shading measures for the machine to avoid the machine temperature rising due to direct
sunlight, causing the machine to run at reduced capacity.
6.1.2 Outdoor requirements
SES-90 is capable of operating within an ambient temperature of -40°C to 60°C.
When the temperature is higher than 45℃the machine will run at a reduced rate. When the
temperature is lower than -20℃, it needs to warm up first before high power operation.
The sunlight irradiation intensity should be ≤1200W/m^2, and it is recommended that the
converter installed outdoors should take the necessary shading measures.
6.1.3 Foundation support requirements
Since the electrical compartment of the energy storage all-in-one cabinet is side air outlet
and the front air outlet of the battery compartment, it is recommended to ensure at least 1m air
ducts on the side and front when installing the all-in-one cabinet.

17
Due to the installation of wall-mounted air conditioning in the battery compartment door of
the integrated cabinet, 350mm space is reserved on the side of the battery compartment to
ensure the normal opening of the door.
The energy storage cabinet needs to be installed on a concrete foundation or a structure
supported by steel channel with a surface of flame retardant material. Must ensure the foundation
is flat and solid, safe and reliable, and has sufficient bearing capacity, strictly forbidden to install
on the surface of the foundation with depression or tilt.
When building the foundation, according to the overall design of the power station and the
location of the cables in and out of the bottom of the energy storage cabinet, the cable trench
should be preset.
Pre-opening holes are required on the base, and the size of the opening holes must be
exactly the same as the positioning holes of the base of the energy storage cabinet, in order to
firmly connect the energy storage cabinet with the foundation.
As shown in Figure 6-1, the base of the energy storage cabinet is equipped with eight
35mm*20mm positioning waist holes, and it is recommended to use M16*45 bolts to fasten the
