Application of Metal Core PCB in Photovoltaic Energy Storage Equipment

As photovoltaic energy storage equipment continues to move toward higher efficiency, miniaturization, and greater reliability, metal core PCBs have become an indispensable key component due to their excellent heat dissipation, mechanical strength, and electrical properties. With years of expertise in metal core PCB manufacturing, mature processes, strict quality control, and extensive experience, HOYOGO provides stable and reliable product support for the photovoltaic energy storage field, helping equipment maintain stable, efficient, and safe operation throughout its entire lifecycle.

In practical applications, HOYOGO’s metal core PCB are widely used in photovoltaic inverters, power conversion systems (PCS), and battery management systems (BMS), playing an irreplaceable role in these core areas.

1. Photovoltaic Inverters

In photovoltaic inverters, the application of metal core PCB is particularly critical. The inverter converts direct current (DC) generated by solar panels into alternating current (AC) that can be fed into the power grid. The power devices inside (such as IGBT, MOSFET, etc.) generate significant heat during high-frequency switching. If the heat is not dissipated in time, the device temperature rises, reducing conversion efficiency and even causing failures.

Metal core PCBs, with their high thermal conductivity (aluminum-based PCBs typically 1–2 W/(m·K), while copper-based PCBs can exceed 200 W/(m·K)), can quickly transfer the heat generated by power devices to heat sinks or enclosures. This effectively controls operating temperatures.

2. Power Conversion Systems (PCS)

As a important device connecting storage batteries and the power grid, PCS also has stringent requirements for heat dissipation and reliability. During charging and discharging, PCS enables bidirectional power conversion, with high power density and significant heat generation inside the circuit.

Metal core PCB not only provide efficient heat dissipation but also offer strong mechanical strength to withstand vibrations and shocks during transportation, installation, and operation, ensuring stability of circuit connections. In addition, the insulating layer of metal core PCB has a high breakdown voltage, meeting the insulation requirements of high-voltage circuits in PCS and reducing the risk of short circuits.

3. Battery Management Systems (BMS)

In the battery management system (BMS) of photovoltaic energy storage systems, metal core PCBs also play an important role. The BMS monitors battery status (voltage, current, temperature, etc.), balances cell charge, and provides safety protection. Its internal components such as sensors and control chips require a highly stable operating environment. 

The uniform heat dissipation of metal core PCB prevents localized overheating, protecting sensitive components and ensuring accurate monitoring and reliable execution of control commands. At the same time, metal core PCB have strong electromagnetic interference (EMI) resistance, which helps reduce the impact of electromagnetic signals generated by other devices in the photovoltaic energy storage system on the BMS, thereby enhancing the overall stability of the system.

With the continuous development of photovoltaic energy storage technology, demands on power density, efficiency, and reliability are rising. As metal core PCB manufacturing technology evolves, its performance will continue to improve, playing a greater role in large-scale solar power storage systems and distributed energy storage equipment, thus providing strong support for the sustainable development of the photovoltaic energy storage industry.
