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 supplies.

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 2-2.

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 greater than the maximum charging current of the
products used in 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 2-2, 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 2-2.
The security check

Firefighting equipment should be provided near the equipment, such as portable dry
powder fire extinguisher.

Automatic fire fighting system shall be provided for the case where necessary.



When the equipment arrives at the installation site, loading and unloading should
be carried out according to the rules and regulations, to prevent from 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.
Packing list is as follows:
