Solar photovoltaic DC combiner box power supply solution

Functions of DC-DC Power Modules

A DC-DC module is a power conversion device that converts a DC input voltage to different DC output voltages. It is widely used in electronic equipment, communication systems, industrial control, and new energy fields. Its functions include: voltage conversion (boost, buck); electrical isolation; voltage regulation and stabilization; efficiency optimization; and protection.

What problems can DC-DC power modules solve for photovoltaic DC combiner boxes?

Traditional photovoltaic DC combiner boxes may affect the normal operation of the entire system when faced with battery string failures. The application of DC-DC modules can improve system reliability. When a battery string fails, the DC-DC module can quickly isolate it, preventing the fault from escalating. At the same time, the DC-DC module can also monitor and adjust the combiner box output in real time, ensuring stable system operation under various abnormal conditions. For example, in severe weather conditions such as heavy rain and strong winds, photovoltaic panels may be damaged, leading to battery string failures. In this case, the DC-DC module can promptly detect and handle these faults, ensuring the reliability of the entire photovoltaic system.
