Honunity Technology Durable Pv Module Connector Mc4 T Branch Connectors With International Standard

【Honunity MC4 Branch Connector】

1. Why HonUnity MC4 Branch Connector?

◆ Excellent resistance to UV, oil, greases, oxygen and ozone;

◆ Excellent resistance to abrasion;

◆ Halogen free, flame retardant,low toxicity;

◆ Excellent flexibility and stripping performance;

◆ Dual wall insulation.Electron beam cross-linked;

◆ High current carring capacity;

◆ TUV/UL/SGS approved.

2. Reliable Quality!

Honunity Technology Solar MC4 Branch Connectors are used to connect two MC4 Connectors in parallel.

Each Branch Connector has 3 branches - two on the one side & one on the other. The branches could be "male" or "female". The construction of the branches is similar to the construction of the MC4 connectors shown in Fig. 1. In a branch connector, all the 3 branches are internally connected in parallel. A Male Branch Connector (marked "+") is shown in Fig 2A. This consists of two MC4 Male Connectors that are connected in parallel with a MC4 Female Connector (marked "+"). This is used to connect two MC4 Female Connectors in parallel.

A Female Branch Connector (marked "-") is shown in Fig 2B. This consists of two MC4 Female Connectors that are connected in parallel with a MC4 Male Connector (marked "-"). This is used to connect two MC4 Male Connectors in parallel.

3.Wire Connection

Wire Connections on Solar Panels (See Fig. 3)

Most solar panels come with approximately 3 ft of Positive (‘+’) and Negative (‘-‘) wire. One end of each wire is connected to the junction box of the panel. In most solar panels (for example, solar panels manufactured by Samlex Solar), the other end of each wire is terminated with an MC4 connector. The Positive (‘+’) wire has a Female MC4 Connector and the Negative (‘-‘) wire has a Male MC4 Connector. To extend the length of the wires of these solar panels for connection to a charge controller, combiner box or grid-connected inverter, an extension wire is required with corresponding Male and Female MC4 Connectors.

Branch Connectors (Fig. 2A and 2B)

Two or more solar panels are connected in parallel to increase the current output at the same voltage.

Fig. 4 above shows the arrangement for connecting two solar panels in parallel using the MC4 Connecting Wire Kit (sold separately) and the Branch Connectors. This arrangement is possible if the two solar panels will be mounted adjacent to each other. The output wires of the two solar panels are connected in parallel using the Male and Female Branch Connectors. The outputs of the Branch Connectors are then connected to the Mc4 Connector Kit wires which connect to the external PV circuit.

Connecting two solar panels in parallel when separated by a distance (Fig. 5)

Fig. 5 above shows an arrangement for connecting two solar panels in parallel when they are separated by an extended distance. In this case, the following will be required:

• SCW-20-2 Connecting Wires - 2 sets (sold separately)

• One Male Branch Connector and one Female Branch Connector

• One MC4 Male Connector and one MC4 Female Connector

Use one pair of the connecting wires and the MC4 male/female connectors to bridge the extended distance between the panels. The Branch Connectors are then used to parallel the two solar panels.

Use the second pair of connecting wires to connect to the external PV circuit. Connect the MC4 connectors to the bare ends of each of the Connecting Wires as follows:

1). Cut the two Mc4 Connector Kit wires to the desired lengths depending upon the distance between the solar panels.

2). Strip 0.25” of the insulation at the ends.

3). Establish the correct polarity by tracing the wires back to the solar panel, if necessary.

4). Crimp the male and female contact inserts (2 and 5 of Fig. 1) to the bare ends of the wire with the help of special purpose crimping tool meant for the MC4 connectors.

5). Install the contact inserts inside the housing of the MC4 connectors and tighten the strain relief / seal (7 of Fig. 1) fully to ensure a watertight seal.

4. Short Lead Time!

HonUnity always keep enough stock of each components in warehouse, thus keeping an short lead time for client and can delivery the cargo within shortest time.
