With the widespread adoption of photovoltaic (PV) systems, installation costs have become a crucial factor for many potential users.

Typically, the lifespan of PV modules is 25 years, while traditional string inverters have a lifespan of 10-15 years. This implies that users need to consider replacing the inverter once during the PV power plant's lifecycle, leading to a second increase in equipment and labor costs.

However, TSUN microinverters stand out by offering a lifespan of 25 years or more, aligning with the module's lifespan. This eliminates the need for additional investments during the PV power plant's lifecycle, reducing operational costs and minimizing investment risks.

In this article, we will uncover the technological secrets behind TSUN Micro Inverter's 25-year lifespan.

Ingenious Design

The body of the TSUN microinverter is crafted using double-sided die-casting to maximize heat dissipation. Internally, the unit adopts a fully encapsulated process, ensuring not only uniform heat conduction but also maintaining a sealed state over an extended period, guaranteeing component reliability.

Additionally, TSUN microinverters achieve an IP67 protection level, effectively reducing the impact of external environments on the casing and connectors, and safeguarding the unit's 25-year design lifespan.

First-Rate Quality

The lifespan of a microinverter depends significantly on its internal electronic components. The internal structure and heat dissipation design protect core electrolytic capacitors, minimizing the impact of high temperatures on their performance. Lower internal temperatures lead to higher efficiency in electrolytic capacitors, thus extending the microinverter's operational lifespan.

Furthermore, TSUN microinverters utilize top-notch components from leading industry brands, ensuring premium quality even in the "invisible" aspects, providing peace of mind for users.

Stable System

In terms of system performance, microinverters have distinct advantages.

Firstly, systems with microinverters operate on a parallel relationship between panels, with each panel having independent Maximum Power Point Tracking (MPPT), ensuring mutual independence and significantly enhancing system reliability and stability.

Secondly, microinverters contribute to better power quality. Precise control of output voltage and current for each solar panel helps reduce current harmonics, thereby improving the overall quality of electrical energy.

Due to its compact size and easy installation, microinverters offer high flexibility in applications. Quick and convenient maintenance also ensures equipment stability throughout its designed lifecycle.

TSUN, relying on outstanding structural design, rigorous quality, and top-tier component selection, ensures the safety and reliability of its microinverter products throughout their 25-year lifespan.
