Photovoltaic grid-connected junction boxes have a wide range of applications and are suitable for AC 50Hz distribution systems with a rated operating voltage of 380V. In centralized and distributed photovoltaic power generation projects, they play a crucial role in connecting the AC electricity generated by inverters to the grid or end-users, ensuring the safe and stable operation of the system. As global demand for clean energy continues to grow, the photovoltaic power generation market has broad prospects. As an important component of photovoltaic power generation systems, photovoltaic grid-connected junction boxes will also see greater market development opportunities.

YHZC series surge protector (Surge Protective Device, referred to as SPD) is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby preventing the surge from damaging other devices in the circuit. Surges are generated from a wide range of sources, such as lightning induction, switch operation, electrostatic discharge, etc.

Learning how to calculate the size of an inverter based on your needs can be a tricky task, especially if you are not familiar with how inverters work or how much power they need to produce. Inverters are useful devices, but in order to make an accurate estimate or find the right answer, you may have the following questions about inverters.

Due to the unstable power quality, it often causes damage to computer hardware, system crashes, and loss of important data. Therefore, the Uninterruptible Power Supply (UPS) has gradually become an indispensable standard component when purchasing computer equipment. However, how to choose a UPS often troubles users, and an important part of a UPS power supply is the battery. To select a good UPS, one must choose a high-quality brand UPS battery.
