Solar photovoltaic junction box is a component used in solar photovoltaic system, its main role is to connect the positive and negative poles of the solar panel, as well as the connection with other photovoltaic system components (such as inverters, battery storage systems, etc.) to ensure the safety and normal operation of the system.
Junction box body: usually made of high-performance materials, such as PPO (polyphenyl ether), with good weather resistance and electrical insulation.
Protection level: IP68 protection level ensures that the junction box has extremely high water and dust resistance and can resist the invasion of rain, dust and other external factors.
Terminal: Used to connect cables to ensure the effective transmission of current. Terminals are usually designed with crimp type wiring, easy and quick installation.
Self-locking system: The embedded self-locking system ensures that the various parts of the junction box are securely connected and not easily loosened.
Flame retardant rating: Through the UL94-V0 flame retardant rating certification, improve system safety.
The design of the solar photovoltaic junction box is easy to install and maintain, simplifies the wiring work of the solar system, and improves the overall performance and reliability of the system.
Current and voltage tolerance: For example, the specification of 1500V 30A indicates that the junction box can withstand high voltage and current, which is suitable for large solar photovoltaic systems.
Low contact resistance: contact resistance ≤0.35mΩ, to ensure the efficiency and stability of the connection, reduce energy loss, improve system efficiency.
Materials with strong weather resistance: The use of PPO materials, with good weather resistance and electrical insulation, suitable for various environmental conditions.
Tinned copper conductor: provides excellent electrical conductivity to ensure effective transmission of current.
Multi-point connection design: Suitable for multi-component connection requirements, providing stable reliability.
Reduced shadow effect: The design of the connector reduces the shadow area on the solar panel, minimizing the impact of shadow on the efficiency of solar power generation.
High voltage and current tolerance: The 1500V 30A specification ensures that the connector can withstand high voltage and current, suitable for large solar photovoltaic systems.
IP68 Protection: Provides the highest level of dust and water resistance, ensuring reliability and durability of connectors in extreme environments.
Crimp wiring: easy and quick installation.
Flame retardant rating: Through the UL94-V0 flame retardant rating certification, improve system safety.
Environmentally friendly materials: PPO material is an environmentally friendly material, does not contain harmful substances, meets environmental standards such as RoHS, and helps to reduce the impact on the environment.
These advantages make the 1500V 30A IP68 solar photovoltaic junction box indispensable in the solar system, not only to protect the safety of the system, but also to improve the overall performance and reliability of the system.
