• Function: MPPT technology is used to adjust solar power generation systems to ensure optimal performance under varying conditions, such as changes in sunlight intensity and temperature. • Efficiency: MPPT efficiency refers to the efficiency with which microinverters track and maintain each solar panel at its maximum power point. The level of efficiency directly affects the output power of each panel. • Impact: High MPPT efficiency means higher output power from the panels, which is directly related to the return on investment for solar energy. In short, the higher the MPPT efficiency, the better the energy output and return on investment of the solar system.

PCS stands for "Power Conversion System," also known as a storage converter in Chinese. It is a device in an electrochemical energy storage system that facilitates the bidirectional conversion of electrical energy between the battery system and the power grid (and/or load). PCS can control the charging and discharging processes of the battery, perform AC/DC conversion, and directly supply power to AC loads in the absence of a power grid. It consists of a DC/AC bidirectional converter and control units. The PCS controller receives backend control commands via communication, and based on the sign and magnitude of the power command, it controls the converter to charge or discharge the battery, regulating the active and reactive power of the power grid. Additionally, PCS can communicate with the Battery Management System (BMS) through CAN interfaces and dry contact transmission to obtain battery pack status information, enabling protective charging and discharging of the battery to ensure safe battery operation.

Our microinverters have a lower start-up voltage, which can extend their service life and reduce maintenance costs. They also support Sub-1G and WIFI communication, enhancing signal anti-interference capabilities and allowing signals to be transmitted further with lower power consumption. A single Sub-1G station can work with multiple microinverters. You might be aware that we are one of the few companies in China certified for Sub-1G. The microinverters also come with a built-in Anti-Power-Reversal Controller (ARPC), which prevents photovoltaic current backflow and improves the conversion efficiency from direct current to alternating current.

The most popular currently are the two-in-one series of 600-800W microinverters. We are able to provide microinverters ranging from 0.3-2kW, and in one-in-one, two-in-one, and four-in-one configurations.

The warranty period can be as long as 25 years. We maintain industry-leading standards through rigorous quality testing. We place great emphasis on product safety.
