3.1 Unpack and inspection
After confirming that the outer packaging is intact, please perform unpacking inspection.
Unpack the box and check whether the appearance of the string inverter is good. When opening
the packing box, you need to use tools carefully to avoid scratching the string inverter;
The string inverter has been rigorously tested and inspected at the factory, but accidental
damage may occur during transportation, so please check the string inverter immediately after
receiving the goods. If you find any damage or omissions, please contact Bluesun
Technology
as soon as possible, our staff will serve you as soon as possible.

3.3 Installation environment requirements
The environmental requirements for the installation of string inverters are shown in "2.10
Ambient Requirements".
The installation method and position must be suitable for the weight and size of the string
inverter, see "2.9 Mechanical Parameters ".
The string inverter should be installed in a well-ventilated environment to ensure good heat
dissipation. Protect the inverter from direct sunlight, rain and snow can extend the life of the
inverter. It is recommended to choose a sheltered installation site. If it cannot be satisfied,
please build a sunshade (optional accessory).
During the operation of the string-type inverter, the temperature of the chassis and heat sink
will be relatively high, please installed the inverter in a location where it will not be accidentally
touched.
Note: This chapter takes Bluesun BSM 30K-B as an example to introduce the cable connection
methods for installation. The interfaces of other models may be a bit different, so please connect
cables according to actual situation while referring to this chapter.
