3.1.3 Technical preparation
Electrical interface check
Devices that can be connected directly to the battery can be user equipment,
power supplies, or other power supplie s.

Confirm whether the user's PV power generation equipment, power supply or
other power supply equipment has a DC output interface, and measure
whether the DC power output voltage meets the voltage range requirements
in Table 2-1 and Table 2-2 .

Confirm that the maximum discharge current capability of the DC power
interface of the user's photovoltaic power generation equipment, power
supply or other power supply equipment should be higher than the maximum
charging current of the products used in Table 2-1 and Table 2-2
.
If the maximum discharge capacity of the DC power interface of the user's
photovoltaic power generation equipment is less than the maximum charging
current of the products used in Table 2-1 and Table 2-2, the DC power
interface of the user's photovoltaic power generation equipment shall have a
current limiting function to ensure the normal operation of the user’s
equipment .

Verify that the maximum operating current of the battery-powered user
equipment (inverter DC input) should be less than the maximum discharge
current of the products used in Table 2-1 and Table 2-2
.
The security check

Firefighting equipment should be provided near the product, such as portable
dry powder fire extinguisher
.

Automatic fire fighting system shall be provided for the case where

being exposed to sun and rain
.

Before unpacking, the total number of packages shall be indicated according
to the shipping list attached to each package, and the case shall be checked
for good condition .

In the process of unpacking, handle with care and protect the surface coating
of the object .

Open the package, the installation personnel should read the technical
documents, verify the list, according to the configuration table and packing
list, ensure objects are complete and intact, if the internal packing is
damaged, should be examined and recorded in detail .
