The ZYBWX PV DC Converter Box is designed specifically for use in photovoltaic power generation systems. It is used to convert DC power generated by photovoltaic cells into AC power that can be used to power household appliances, industrial equipment, and other electrical loads.

The ZYBWX PV DC Converter Box is suitable for a wide range of applications, including residential and commercial solar power systems, solar power stations, and other photovoltaic power generation systems. It is particularly useful in remote areas where grid power is not available or unreliable, as it provides a reliable and efficient source of electricity.

In addition to its conversion function, the ZYBWX PV DC Converter Box is also equipped with advanced control and protection functions, such as overvoltage protection, overcurrent protection, and short-circuit protection, to ensure the safety and stability of the power supply system.

Overall, the ZYBWX PV DC Converter Box is an ideal solution for photovoltaic power generation systems, providing efficient and reliable conversion and control of DC power to AC power for use in a wide range of applications.


ZYBWX lightning protection confluence box is to combine the DC input confluence of up to 24 channels photovoltaic battery pack string into one or more output, each circuit is equipped with fuse wire, and the transmission line is equipped with lightning protector and circuit breaker, which greatly simplifies the input wiring of DC distribution cabinet and inverter. Provide lightning protection, short circuit protection and grounding protection. The confluence box is divided into two types: intelligent and non-intelligent. The intelligent lightning protection confluence box is equipped with a confluence monitoring unit, which can monitor the current input from each photovoltaic cell string, the aggregate transmission voltage, the temperature in the box and the state of the lightning protector, the state of the circuit breaker, etc.

The internal arrangement of the device is simple and clear, and the wiring is neat and reasonable. high reliability and simple maintenance. Outdoor wall mounted installation, can adapt to all kinds of harsh environment. In addition to the relevant core components, others can be customized according to user requirements.

 Functional characteristics

♦ The protection grade of the junction box reaches IP65, with waterproof, ash-proof, rust-proof, and salt-spray-proof to meet the requirements of outdoor installation;
♦ Can connect up to 24 battery strings at the same time;
♦ The positive and negative poles of each battery string are equipped with special photovoltaic fuses to protect the component string from failure. The fuse base and fuses are used together to reduce the owner’s later maintenance costs and effectively protect the personal safety of maintenance personnel;
♦ The special high-voltage lightning protector for photovoltaic can protect the positive pole and the negative pole of the busbar after the convergence, and the continuous working power (Uc) can reach 1000VDC; the power module in the junction box can be connected to the photovoltaic voltage of up to 1000DCV;
♦ The combiner box measurement and control module uses reliable Honeywell Hall elements (DC CT sensors) to collect and monitor the current and bus voltage of each PV string, alarm and local fault location, and can Temperature measurement, status detection of lightning protector and output circuit breaker, etc.;
♦ The monitoring module in the combiner box has a digital display function, which can display the current of each component string, the bus voltage, the temperature in the combiner box, the status of the circuit breaker surge protector, the system power and the device address on the device;
♦ With RS485/MODBUS-RTU serial communication;
♦ Lightning protection is provided with the external interface;
♦ Can receive the parameter download of the local monitoring device for analysis and processing;
♦ The working power of the combiner box can be selected from the external 220VAC/DC or the power supply provided by the combiner box itself. If the combiner box itself is used to provide power supply, there is no need for separate wiring for power supply on site
