What is Solar Bonding Grounding Jumper?

Solar Bonding Jumper is a crucial safety component in a photovoltaic (PV) system. Its primary purpose is to create an electrically continuous path to ground for fault currents, ensuring that all metal parts that could potentially become energized are at the same electrical potential.

In simpler terms, it’s a wire that connects all the exposed metal parts of a solar array together and then to the grounding system, preventing electric shock and fire hazards.

Solar grounding jumper is an important component used in solar power generation system, mainly used to introduce excess charge into the earth to ensure the safety and reliability of the system.

The following will introduce the solar bonding jumper in detail from the aspects of working principle, material selection, scale type and selection method.

Working principle
The system works on the principle of Equipotential Bonding. By connecting all metal parts together with a low-impedance conductor (the bonding jumper), they are forced to remain at the same voltage, even during a fault. If a fault occurs, the current takes the path of least resistance (the bonding wire) back to the source, tripping the overcurrent protection device almost instantly.

The principle is to use the conductive properties of the ground to connect the zero potential of the system to the earth so that unexpected current will not accumulate in the system, thereby ensuring the stability and safety of the circuit.

Material selection
The material of solar grounding jumper is usually made of metal materials with good conductivity, such as copper, aluminum, stainless steel, etc. Different materials have their own advantages and disadvantages:

Copper: It has high conductivity and corrosion resistance and is widely used in various solar energy systems. Although the price is higher, its good conductivity and durability are more advantageous in long-term use. Our Solar Bonding Jumper is made of Copper.

Copper tape is particularly suitable for any application that is directly used outdoors. After the small-gauge wires and tinned copper braid are weathered and decomposed, they can maintain a proper low-impedance connection. Copper strips are widely used in photovoltaic installations and are perfectly connected to the guide rails. They are available in various widths and thicknesses to suit your application.

The copper bonding strap is a sturdy and flexible metal strap used to build a high-performance grounding system. The use of these copper strips provides the best grounding system, plays a good conductive role, and ensures the safety of the device.

Feature:

1. Customized can be provided;
2. The copper braid can be used to connect between the guide rails, and conduct electricity;
3. Provide better electrical connection;
   4.Metal nuts, bolts and washers have good electrical contact;
4. Suitable for various grounding applications;
5. High quality bonding jumpeer for PV system grounding;

The Solar grounding jumper for solar mounts is a very convenient and economical product. It is one of the important components for installing solar energy systems. It is used for connection between rails and conducts electricity. It’s used to connect two rails with grounding strapes.

The Solar grounding jumper also plays a key role in lightning protection. When a lightning strike occurs, the grounding strip will guide the lightning current to the ground to prevent damage to the solar equipment.
