PV Connector

In the world of solar energy, photovoltaic (PV) connectors, also known as solar connectors, are the unsung heroes that ensure a smooth flow of power. These weatherproof workhorses act as connection points between solar panels, cables, and other vital components within your solar system. By securely linking these elements, PV connectors guarantee the uninterrupted transfer of direct current (DC) electricity generated by your solar panels. This seamless connection is fundamental for optimal solar energy production, making PV connectors a crucial part of any efficient and long-lasting solar power system. Look for industry-standard connectors like MC4, known for their durability, secure locking mechanisms, and ease of installation, to maximize the performance and lifespan of your solar investment.

How to Install

Don't underestimate the power of a tiny box! Photovoltaic junction boxes, often called solar junction boxes, are the unsung heroes of your solar energy system. These weatherproof enclosures, strategically placed on the back of each panel, play a critical role in ensuring safe, efficient, and long-lasting solar power generation. By housing and protecting the electrical connections between solar cells, junction boxes prevent exposure and potential damage. They also often contain bypass diodes that maintain energy flow even in shaded areas, maximizing your system's output.

Furthermore, some junction boxes offer surge protection, safeguarding your valuable solar investment from electrical spikes. For a reliable and high-performing solar power system, proper installation of photovoltaic junction boxes is a non-negotiable step.

Step 1

Strip the insulating layer of cable. L=7±0.3mm.Be attention and not to cut off the wire core.

Note: Please keep the cable cross section flat when cutting the cable.

Step 2

Put the stripped cable into the terminal hole and ensure that all cores are in the terminal hole.

Do not touch the positioning angle of the terminal

Step 3

Push the riveted pin into the insulator until they engage. Pull lightly on the lead to check that the metal part has engaged.

Step 4

Install the cable gland. First screw it by hands, then lock tightly by plastic spanner or plastic spanner and ring spanner. The front-end of connector need to be fixed during Production. Unscrew the rear cover, recommended input torque force 3.0N.m

Step 5

Insert male connector and female connector until they

engaged, which can verify whether the connector is in

place.

Note: Plug parts of the cable coupler together until they click in place. When connection is completed, the cable can be pulled to the left and right direction to confirm whether the connector is assembled well.

Step 6

The connectors can be unlocked by hands.

The cable of connector should not be bend too much, the minimum bending radius should be not more the four times of cable O.D generally . For accurate information , refer to cable manufacture’s specification.

Safety Measures

Safety

During your self- installation, if the used part and tool are not ruled by us or if you ignore our preparation and operation, we can't insure the safety and compatibility of the product technology of your self-installation.

Resistance

H07RN cables without tinned are not recommended. Cause the contact resistance of crimping place

will probably exceed the permitted value since the cooper wires are oxidized.

Electricity

For protecting against electric shock, please cut off the power when installing PV connector.

The final products must be supplied with the function electric shock proof.

Water-resistance

TL-CABLE01 are IP67 rated, and they can be positioned for half an hour under 1MT of water, But they can’t be put under water for long time.

Overload

In the case of the load, the connector is not allowed to be disconnected . In the case of it charging , it is not allowed to pull the plug.

Reactions

Some chemicals should avoid contacting with the connector body
