Cables And Wires; Connector; Bypass Diode - Hyundai HiE-S UF Series Installation Manual

If there may be a reverse current through the module that exceeds the maximum fuse current, the module must
be protected by over-current protection. If the number of parallel connections is greater than or equal to 2, an over-
current guard must be installed on each assembly.
Do not install in rainy weather, moisture will lead to insulation failure, prone to safety accidents.
For specific electrical performance parameters, please refer to the product specifications.

Cables and wires

The junction box of each module is equipped with two separate wires, one positive and one negative, which can
be connected in series by inserting the positive connector of one module into the socket of the negative connector of
the adjacent module.
During installation, do not use lubricating oil or alkane cleaning agents to clean connectors, junction boxes, and
cables.
The cross-sectional area of the cable and the capacity of the connector must meet the maximum short-circuit
current of the module (for a single module, the cross-sectional area of the cable is 4mm
ranges from -40 ° c to +90 ° c).
When the cable is fixed on the bracket, it is necessary to avoid mechanical damage to the cable or module. The
cable is fixed on the bracket with specially designed light resistant tie and cable card. The cable is light resistant and
waterproof, and also avoid direct sunlight and water soaking the cable.

Connector

When connecting modules, ensure that the connectors of the same string of modules are from the same
manufacturer or fully compatible, and the connection terminals of the modules and the system must also be in the
same way. The connectors of different manufacturers may be incompatible, which may cause mismatching and
burning.
Keep the connector dry and clean.
Do not connect the connector when it is damp or dirty.
Do not expose the connector to direct sunlight or water.

Bypass Diode

The junction box of the Hyundai Energy Solution module contains the bypass diode and forms a parallel structure
with the circuit. When the solar cells of the module is blocked or damaged, the hot spot phenomenon occurs in the
part of the module, the diode will work, so that the current no longer flows through the hot spot solar cell, so as to
limit the heating and performance loss of the module.
Note that the bypass diode is not an over-current protector.
