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.
