During the summer, the PV system benefits from ample sunlight, enabling it to absorb more solar energy. Nevertheless, the system faces notable challenges in maintaining safety and efficiency due to the elevated ambient temperatures and frequent occurrence of thunderstorms.

In this blog, we’ll discuss how does TSUN, the provider of the world’s most complete range of microinverters from 300W to 3000W, handle these challenges?

Heat Dissipation and Lightning Protection Level for Enhanced Safety

The hot summer poses significant challenges for all equipment and components in a solar power plant. Components such as motors, transformers, inductors, and various plastic cables have limited tolerance to high temperatures. Excessive heat can cause insulation degradation, insulation breakdown, short circuits, explosions, or even fires.

Moreover, thunderstorms bring strong airflows that may come into contact with tall structures and outdoor communication facilities at the solar power plant. Without proper grounding protection, this can lead to lightning strikes, damaging cables, causing loose connections, electrical faults, or even fires, resulting in significant losses.

To address these issues, TSUN microinverters use aluminum casings to enhance heat dissipation. The internal components are encapsulated using a full potting process, ensuring uniform heat distribution and stable output power within a temperature range of -40ºC to +65ºC, effectively reducing the failure rate.

To safeguard against lightning, TSUN microinverters implement multiple grounding measures to ensure normal operation during thunderstorms. Additionally, the inverters feature instant protection against overheating, overcurrent, and overvoltage, automatically disconnecting the connection in case of system faults to ensure safety.

High Conversion Efficiency to Minimize Power Loss

While it is commonly believed that solar systems maximize power generation during summer, the reality is not always like this. Microinverters operating for a long time at high temperatures may undergo derating or shutdown, leading to power generation losses. Additionally, solar panel performance declines as temperatures rise, with each degree increase resulting in a decrease in output power by 0.38% to 0.44%.

Microinverter from TSUN adopts advanced technologies such as microinverter topology, soft switching, and power module active parallel techniques, providing industry-leading performance in power density, power range, and conversion efficiency.
The TSUN TITAN series TSOL-MS3000 microinverter, the world's most powerful single-phase microinverter for residential PV systems, achieves a peak efficiency of 97.2% and a CEC weighted efficiency of 96.7%, which is at the forefront of the industry.
Moreover, TSUN microinverters are equipped with multiple independent MPPTs, adjusting the output power of the PV array based on external factors such as ambient temperature and solar irradiance, ensuring the solar array operates at its maximum power output.

IP67 Level to Guarantee the System Durability

Frequent rains in summer can damage electrical equipment insulation, posing risks to system safety. This may also result in short circuits and overheating of microinverters, leading to electrical faults and accelerating corrosion of solar modules, ultimately reducing the overall lifespan of the solar system.

The TSUN microinverters are designed with an impressive IP67 protection level, ensuring exceptional waterproof and dustproof capabilities. They can easily withstand frequent summer rain and can even maintain excellent performance when submerged in water. With this level of protection, TSUN microinverters offer unparalleled equipment reliability and serve as a dependable safeguard throughout their 25-year service life.

Intelligent Monitoring System for Simplified Maintenance

Distributed PV systems are smaller and more flexible than centralized ones. However, this setup also makes system operation and maintenance more challenging. When a fault occurs, maintenance staff must inspect each solar module individually to identify the issue. Thunderstorms further hinder on-site maintenance efficiency due to slippery ground and limited visibility. Submerged PV modules can experience insulation issues and pose electrocution risks, threatening personal safety.
To tackle these challenges, TSUN microinverters are equipped with module-level monitoring systems, enabling real-time monitoring of voltage, current, and power generation efficiency for each module worldwide. All products have built-in Wi-Fi and Bluetooth communication modules, which make the system’s data accessible through the Talent Monitoring platform via smartphones or computers.

Once the system breaks down, maintenance staff can perform remote fault diagnosis and analysis through the Talent Monitoring platform, quickly pinpointing the problem. They can also execute remote software upgrades and power adjustments, effectively managing the challenges posed by adverse weather conditions and significantly reducing the overall operational costs of the PV system throughout its entire lifecycle.

With cutting-edge PV technology, innovative product design, advanced protection level, and intelligent maintenance systems, TSUN microinverters withstand the dual challenges of heatwaves and thunderstorms, providing a safe, efficient, and reliable solar solution for residents all over the world.
