Enphase is changing the solar industry with its revolutionary microinverter technology.

 

 

 

According to Q1 2024, Enphase still continues to reduce shipments this quarter to manage channel inventory and reduce the pressure of the weak U.S. microinverter market.

 

 

 

The M215 PV grid-connected microinverter compares favorably to the rest of the Enphase M series, as the former is lighter in weight and does not require a DC design. It is suitable for long-time operation and high security requirements.

 

 

 

 

 

 

M215 adopts the main control chip developed in-house, and the peak output power can reach 225VA.

 

 

 

The input filter capacitor comes from Japan's Guiyangong, two parallel KY series electrolytic capacitors. Filter capacitors are used in the power rectifier circuit to filter out the AC component, so that the output DC is smoother and the inverter works more stable.

 

 

 

MOS tubes come from two brands, Infineon and ST STMicroelectronics. The Infineon MOS model BSC190N15NS3-G is used for boosting and has an withstand voltage of 150 V. The ST MOS is used for output modulation and has an withstand voltage of 800 V. The switching chip is from ON Semiconductor.

 

 

 

The switching power supply chip is from ON Semiconductor. A switching power supply chip is a semiconductor device that integrates switching tubes, control circuits, protection circuits and other functions. It utilizes high-frequency switching technology to convert the input AC power into a stable DC output. Compared with traditional linear power supply, switching power supply has higher conversion efficiency and reduces energy waste.

 

 

 

Resistors come from Lite-On's varistors for overvoltage protection and surge suppression at the output. Varistors are one of the many classifications of resistors and are mainly used in transient overvoltage protection to prevent damage that may be caused to circuits due to sudden transient voltage changes in the power supply system.

 

 

 

Waubond Electronic's memory is used for parameter storage, such as input voltage, output voltage, and frequency. These parameters serve as a record of the inverter's operating status and output quality, facilitating knowledge of the inverter's status and timely maintenance.

 

 

 

Energy demand triggered the microinverter market in 2022, the high inventory in Europe in the past two years led to a decline in microinverter shipments, the market cooled down and gradually returned to normalized growth. According to Enphase projections, micro inverter channel inventory is expected to return to normal by the end of the second quarter, in the third quarter shipments are expected to return to growth.
