With the intensification of global warming, the Earth is facing unprecedented climate challenges. Changes in climate patterns have resulted in increasingly frequent and extreme high-temperature weather conditions in many regions. Extreme high temperatures have become the new normal rather than the exception. From scorching summers to desert areas, high-temperature weather has brought numerous adverse impacts worldwide.

Global warming and extremely high-temperature weather pose significant challenges to the operation of photovoltaic (PV) systems. PV systems are environmentally friendly energy solutions that convert solar energy into electricity. However, high-temperature environments have a detrimental effect on the performance and stability of PV systems. PV panels may face overheating issues in high-temperature environments. Microinverters, which are typically installed under the PV modules or module frames exposed to intense sunlight, can experience temperatures 20-30 ℃ higher than the ambient temperature. In enclosed environments beneath high-power PV panels, the temperature can even exceed 70 ℃ when the outdoor temperature reaches 45 ℃.

High-temperature environments present severe challenges to the stability and reliability of microinverters. As the ambient temperature rises, microinverters may encounter overheating issues, resulting in reduced output power, decreased conversion efficiency, or even equipment damage. Therefore, the high-temperature characteristics of the main control chips and key components chosen for microinverters should surpass those of regular string inverters. Additionally, thermal management is crucial for microinverters. Excellent and adequate heat dissipation design can effectively lower the internal temperature of microinverters, enhancing their thermal stability and operational performance.

In addressing this challenge, the complete range of Beny microinverters demonstrates exceptional performance characteristics and high reliability, providing the optimal solution for PV systems in high-temperature environments while effectively reducing operational costs.

Through rigorous testing and validation with real-world application data, Beny microinverters have demonstrated outstanding performance in high-temperature weather conditions. When the ambient temperature reaches 50℃, Beny microinverters can maintain 100% output power without any reduction in capacity. Even under extreme high-temperature conditions, such as 70℃, Beny microinverters can still maintain 70% output power, surpassing the performance of other inverters. This remarkable performance is attributed to the excellent design and technological innovation of Beny microinverters.

Beny microinverters employ high-temperature-tolerant component designs, with the main control chip selected as an NXP automotive-grade chip, which possesses high resistance to elevated temperatures and stability, ensuring reliable operation in high-temperature environments. Furthermore, all major power devices such as Mosfets, SiC diodes, SCR, and driver chips are sourced from top-tier brands, with a design margin taken into account. Beny microinverters use components that are all rated at 105 degrees Celsius and above, strictly adhering to the photovoltaic industry’s aging model and designed and selected based on a minimum MTBF of 30 years.

Moreover, the Beny 600W single-channel micro inverter has a comparable size to dual-channel and quadruple-channel microinverters from Company H, providing sufficient heat dissipation area. Beny’s surface treatment process possesses a high thermal radiation coefficient and thermal conductivity, enabling excellent heat exchange in different application scenarios, including conduction, convection, and radiation. Outstanding heat dissipation design can significantly lower the internal temperature of microinverters, greatly improving their thermal stability and performance. Heat dissipation treatment is a critical factor in micro inverter operation. Beny’s full and uncompromising heat dissipation design not only demonstrates professionalism in micro inverter design but also reflects a high level of commitment to product reliability, ensuring that the actual operational performance is not compromised for cost reduction. Beny’s heat dissipation design reduces temperature accumulation and risk of failure, prolonging the service life and reducing operational costs. It can operate continuously in high-temperature environments, ensuring stable power generation in photovoltaic systems and providing reliable electricity output.

Therefore, with its exceptional performance, reliability, and design innovation for high-temperature environments, Beny microinverters are the ideal choice for photovoltaic systems. Whether under extreme high-temperature conditions or for long-term operation, Beny microinverters can maintain stable performance and provide reliable and efficient electricity output. For photovoltaic system operators and users facing high-temperature challenges, choosing Beny microinverters is a wise decision that ensures system stability, efficiency, and longevity.
