Photovoltaic system components

A battery connector cable is a conductive wire harness used to connect a battery to other electronic devices or chargers, playing a vital role in transmitting electrical energy. Battery connector cables have the following characteristics: - They have good electrical conductivity to reduce resistance and loss, improving the efficiency of energy transmission. - They have a certain mechanical strength to withstand external tension, pressure, and other stresses, ensuring the stability and safety of the connection line. - They have good heat resistance to withstand the high temperatures generated during the battery charging and discharging process. - They have good flexibility for easy installation and disassembly, reducing the impact on the equipment.

MC4 connectors are specially designed for photovoltaic (PV) systems and are widely used to connect solar panels. The full name of MC4 is Multi-Contact, and 4 represents the diameter of the socket and plug is 4mm. MC4 connectors are a type of single pole connector, meaning that each connector can only connect one wire, one negative and one positive. The design of these connectors allows them to maintain reliable electrical connections under adverse environmental conditions. They have good waterproof and dustproof performance, and can withstand high temperatures, high humidity, and other harsh weather conditions.

The DC Battery Switch is a crucial component used in various applications to control the power supply from a DC battery source. This switch is designed to handle DC loads and effectively disconnect the battery when needed. It is typically used in automotive, marine, and other applications where DC power is used. The switch ensures the safe operation of the equipment by controlling the power flow from the battery. It is designed to handle high current and voltage, and it is usually robust and durable to withstand harsh conditions. It can also protect the battery from over-discharge, thus extending the battery's lifespan. The DC Battery Switch is easy to install and operate and is an essential safety device in any DC power system.

DC Fuse is a type of electrical equipment mainly used to protect electrical devices or circuits in direct current (DC) systems from damage caused by overcurrent. When the current exceeds a set value, the fuse will automatically cut off the circuit to prevent electrical devices or circuits from being damaged by overcurrent. DC fuses are generally used in new energy vehicles, solar photovoltaic systems, power systems, wind power generation systems, and other DC power supply systems. Its main role is to protect electrical devices or circuits in DC power supply systems from overcurrent damage.

DC surge protector is an electronic device used to protect electronic devices from DC surge damage. In modern power systems, high voltage pulses, namely surges, can occur due to lightning strikes, switch operations, or system failures. The generation of surges can cause serious damage to electronic devices, and even lead to system paralysis. DC surge protectors can conduct and divert currents in a very short period of time, effectively absorbing sudden and huge energy, thereby protecting connected equipment from damage. The main features are as follows: it can quickly respond to surge signals in nanoseconds, timely cut off or divert surge currents, and protect electronic devices from damage. Has strong surge absorption ability and can handle various types of surge signals, such as lightning strikes, switch operations, etc. With low insertion loss, it will not have a significant impact on signal transmission, ensuring the normal operation of electronic devices using advanced materials and technology, achieving smaller size and lightweight design, making it easy to install and deploy.

The Molded Case DC Circuit Breaker (hereinafter referred to as the circuit breaker) is one of the new type of circuit breakers developed and developed using international advanced design and manufacturing technology. Its rated insulation voltage is DC1500V, which is suitable for circuits with a direct current of 1250A, for infrequent switching and infrequent motor starting. The circuit breaker has overload, short circuit and under voltage protection devices, which can protect the line and power equipment from damage.
