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 higher 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 product, such as portable dry powder
fire extinguisher.
⚫
Automatic fire fighting system shall be provided for the case where necessary.
⚫
No flammable, explosive and other dangerous materials are placed beside the battery.
3.1.4 Unpacking inspection
⚫
When the equipment arrives at the installation site, loading and unloading should be carried

⚫
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.
