Photovoltaic Power Generation Is Becoming A Major Trend In The Future

With high oil and gas prices and the rise of electric vehicles, photovoltaic power generation has become a major trend in the future. 그만큼 인버터 is the "heart" of the photovoltaic power generation system, which can maximize solar cell performance and system fault protection.

(Microinverter)

Enphase Energy (code: ENPH) is the world's number-one microinverter manufacturer. The company was founded in 2006 and is headquartered in Fremont, California. As of June 15, Enphase's market value was $25.45 billion. Although the S&피 500 index fell more than 20% this year, the stock still bucked the trend and rose more than 3%.

Unlike traditional photovoltaic inverter methods, micro-inverters are directly integrated with individual photovoltaic modules (directly converting current into each component) and track the maximum power peak, thus greatly improving the system's overall power generation efficiency and power generation. , and can also monitor the working status of each component (can quickly find out which component has a problem). Microinverters have the characteristics of small size, 경량, 그리고 안전. The unit capacity is generally less than 1kW, which is also sought after by small and medium-sized industrial, commercial and household users.

Enphase's revenue in 2021 will be US$1.382 billion, a year-on-year increase of 79%, with a gross profit margin of 40%; net profit will be US$145 million, a year-on-year increase of 8% (due to the company's R&디, revenue, and administrative expenses doubling year-on-year), net profit The interest rate is 10%. The company's products include micro-inverters, energy storage batteries, tram charging piles, 등. From a regional perspective, the United States contributed 80% of revenue and other regions contributed 20%.

Application areas of microinverters

1. Solar photovoltaic system

In a home solar photovoltaic system, a microinverter can convert the DC power generated by solar panels into AC power to meet the daily power needs of the home. 동시에, microinverters can provide a reliable power supply and reduce energy costs for small commercial facilities such as shops, restaurants, 등. 게다가, micro-inverters can be used in solar irrigation systems, greenhouse power supply, 등., to improve agricultural production efficiency in the agricultural field.

2. Wind energy power generation system

Microinverters can be used in small-scale wind power systems on land to convert wind energy into electrical energy to provide power to remote areas. In distributed wind power projects, microinverters can be used with large wind turbines to improve overall power generation efficiency.

3. Battery energy storage system

In-home energy storage systems, microinverters can convert DC power stored in batteries into AC power to achieve a self-sufficient power supply. 동시에, microinverters can provide reliable power guarantees for commercial facilities that require backup power to ensure the normal operation of key equipment.

4. Other fields

Microinverters can provide AC charging piles for electric vehicles to facilitate user charging. Microinverters can also be used in outdoor activities, emergency rescue and other scenarios to provide mobile power for electronic devices. In the ship's power supply system, micro-inverters can provide reliable power guarantees and ensure the ship's normal operation.
