F-class microinverters

Product introduction

Microinverters are module-level photovoltaic inverters that enable independent power conversion and maximum power point tracking (MPPT) for each photovoltaic module. Through fine-tuning the output power of each string, they significantly improve the overall power generation efficiency and safety of the system, while enhancing system reliability and simplifying the design, installation, and operation and maintenance processes of solar systems.

This series of high-power microinverters boasts an output power of up to 2000W, featuring module-level MPPT and real-time data monitoring, making operation and maintenance more convenient. Its grid-connected inverter efficiency can reach up to 96.5%, and it is equipped with an IP67 protection rating, adapting to harsh environments and exhibiting excellent reliability. The product integrates multiple electrical protections including overcurrent, short circuit, overvoltage, and overfrequency protection, and supports WiFi wireless communication to ensure stable data transmission. Adopting a 2-in-1/4-in-1 modular design, it offers flexible and convenient installation and is widely applicable to various distributed photovoltaic power generation scenarios.
