PVTIME – With the increasing popularity and wider application of photovoltaic (PV) systems, users have raised higher demands for safety, power generation, flexibility, and intelligent operations in solar power plants. Microinverters, as a new type of PV device, offer several advantages over traditional DC optimizers.
Enhanced Safety and System Stability
DC optimizers are separate devices that enable maximum power point tracking and rapid shutdown functions. In PV systems using string inverters with DC optimizers, a failure in the inverter will completely shut down the entire system. Furthermore, as the modules are connected in series, the system carries a high DC voltage, making it prone to DC arcing and fire hazards caused by loose connections, poor contacts, dampness, or insulation failures.
With the mission of “More Safety, More Power,” TSUN’s microinverters offer advanced features that enhance both safety and reliability. One notable advantage of microinverters is their low-voltage parallel connection, which ensures that the DC voltage on the rooftop remains below 60V, significantly reducing fire risks. Additionally, TSUN’s microinverters feature module-level rapid shutdown, enabling quick disconnection between modules in critical situations, thereby enhancing the system’s safety.
Moreover, microinverters provide exceptional fault tolerance. In systems using microinverters, if specific modules are shaded or encounter faults, the rest of the system continues to operate independently and unaffected. This ensures maximum power output even in the presence of issues. This fault isolation capability allows for swift detection and repair of faults, minimizing system downtime and improving overall reliability.
TSUN’s microinverters also possess a high level of protection with an IP67 rating. This rating guarantees optimal performance even under significant temperature and humidity variations. The robust protection offered by TSUN’s microinverters ensures the long-term durability and reliability of the entire PV system, regardless of challenging environmental conditions.
Plug-and-Play and Simplified Installation
In PV systems using string inverters with optimizers, careful consideration is required during the installation process to design the series connection of the modules. This necessitates meticulous planning and calculations to ensure the system’s optimal performance.
Microinverters, on the other hand, significantly simplify the installation process of the PV system. Their “plug-and-play” installation approach eliminates the need for intricate wiring configurations, streamlining the installation steps and reducing the likelihood of errors that may occur during installation, thus improving installation efficiency.
According to a survey by the Solar Energy Industries Association (SEIA), solar system installers reported that the installation time for systems using microinverters can be reduced by an average of 15% compared to systems using DC optimizers.
Flexible Expansion and Innovative Applications
In PV systems using optimizers, careful planning of the system size during installation often leads to time-consuming reconfigurations or expansions in the future.
However, with the use of microinverters, PV systems can be designed and laid out with greater flexibility. TSUN’s Gen3 series microinverters can be connected to individual modules, allowing each module to be installed on rooftops with different orientations or tilt angles. This maximizes the utilization of solar resources, making it particularly suitable for complex or irregular roof structures, such as multi-faceted roofs or partially shaded areas.
Moreover, TSUN’s microinverters are not limited to traditional roof installations. The TSUN Easy Solar Kit offers an integrated balcony solar system that includes microinverters, modules, brackets, and cables. This kit is suitable for diverse installation scenarios such as rooftops, flat grounds, railings, walls, and more. It caters to the personalized energy needs of users, providing innovative and adaptable solutions.
Microinverters offer powerful safety features that effectively reduce the risk of fire and electric shock hazards. The simplified installation process improves installation efficiency, while the flexibility in expansion and innovative applications provides personalized energy solutions.
