以下沉產(chǎn)業(yè)鏈為根基，潮電智庫(kù)特選出逆變器行業(yè)系列明星產(chǎn)品進(jìn)行拆解，旨在通過展現(xiàn)內(nèi)部核心結(jié)構(gòu)件及成本占比，為中國(guó)供應(yīng)鏈找到更準(zhǔn)確的商機(jī)落點(diǎn)。

繼陽(yáng)光電源SG125HV、古瑞瓦特MAX 80KTL3 LV、固德威GW15K-SDT之后，本期拆解主角為微逆行業(yè)絕對(duì)龍頭Enphas的IQ7+。

Enphase Energy, Inc于2006年3月在美國(guó)特拉華州成立，目前是全球第一的微型逆變器制造商，主打產(chǎn)品為IQ系列微型逆變器。

本次拆解的IQ7+，即IQ系列第7代微型逆變器產(chǎn)品，支持72片的光伏組件，輸出功率達(dá)到290VA；內(nèi)置快速關(guān)閉合規(guī)，用于戶外分布式光伏發(fā)電。因?yàn)椴捎盟芰贤鈿?，?nèi)部灌膠密封工藝，該款微逆僅有938克，不到1公斤的重量。

潮電智庫(kù)拆解所得，Enphase IQ7+主要供應(yīng)商依然由多國(guó)“聯(lián)合部隊(duì)”構(gòu)成。核心IGBT與MOSFET芯片基本由海外大廠牌英飛凌和安森美壟斷；與之前陽(yáng)光電源、古瑞瓦特、固德威等國(guó)產(chǎn)逆變器不同，IQ7+的MCU芯片由Enphase自研；電感、PCB、散熱器等結(jié)構(gòu)件，則分別由來自中國(guó)的伊戈?duì)枴?/span>駿亞科技、AVC（臺(tái)灣地區(qū)）主供。

必須指出，在潮電智庫(kù)的拆解內(nèi)容中，雖然伊戈?duì)柍霈F(xiàn)在多家一線企業(yè)明星逆變器產(chǎn)品的主力供應(yīng)鏈陣容中，但營(yíng)收業(yè)績(jī)并沒有順勢(shì)起飛。

年報(bào)數(shù)據(jù)顯示，去年全年伊戈?duì)枺?02922.SZ）營(yíng)收28.21億元，同比增長(zhǎng)26.5%；凈利潤(rùn)1.92億元，同比微增1.63%。今年第一季度，伊戈?duì)枲I(yíng)收6.39億元，同比增長(zhǎng)0.49%；凈利潤(rùn)1902.92萬(wàn)元，同比大幅下滑45.55%。

“增收不增利”的局面，可見逆變器供應(yīng)鏈內(nèi)卷程度急速加劇中。

7月初，Enphase官方表示，目前公司微型逆變器已開始從美國(guó)首批發(fā)貨。每個(gè)制造工廠的資本投資將接近2000萬(wàn)美元，共投產(chǎn)3個(gè)工廠總計(jì)6000萬(wàn)美元。所有3座工廠建成時(shí)，將使Enphase能夠每季度生產(chǎn)450萬(wàn)個(gè)，或每年生產(chǎn)1800萬(wàn)個(gè)微型逆變器IQ8。

值得注意的是，拜登考察了Flex工廠。他宣稱自他擔(dān)任總統(tǒng)以來，美國(guó)在整個(gè)太陽(yáng)能供應(yīng)鏈上已經(jīng)發(fā)布了60多項(xiàng)國(guó)內(nèi)制造公告。

Enphase IQ7+: A Breakdown of Leading Microinverter Unveils Key Chinese Suppliers

In a bid to shed light on the intricate world of microinverters, ChaoDian presents an exclusive dissection of Enphase's IQ7+.

As the world's premier microinverter manufacturer, Enphase Energy, Inc. has made remarkable strides in the industry with its IQ series microinverters.

The IQ7+, which is the 7th generation of the IQ series, is the focal point of our dissection. Boasting compatibility with 72 photovoltaic modules and an impressive output power of 290VA, this microinverter features built-in rapid shutdown compliance tailored for outdoor distributed photovoltaic power generation. Remarkably lightweight at just 938 grams, this marvel of technology showcases a plastic housing and resin sealing process for optimal performance.

Delving into the supply chain, Enphase IQ7+ continues to form a formidable "united front" with suppliers hailing from multiple countries. The core IGBT and MOSFET chips remain monopolized by overseas giants like Infineon and ON Semiconductor. In contrast to domestic inverter manufacturers, Enphase's MCU chip is an in-house creation. Key structural components, including inductors, PCB boards, and heat sinks, are proudly provided by prominent Chinese companies Igor, Junya Technology, and AVC (Taiwan).

It is noteworthy that Igor, a mainstay in several prominent supply chains, has yet to see a proportional surge in revenue. In the past year, Igor recorded a revenue of 2.821 billion yuan, marking a 26.5% year-on-year increase. However, the net profit saw a modest 1.63% increase, reaching 192 million yuan. Alas, Igor's first-quarter revenue showed a marginal 0.49% year-on-year increase, while net profit experienced a substantial decline of 45.55%.

As Enphase Energy officially announced the commencement of microinverter shipments from its US facilities, President Biden's visit to the Flex factory further emphasized the significance of domestic solar manufacturing, with over 60 announcements being made across the entire solar supply chain since he took office.

The ChaoDian's dissection endeavors to shed light on the complexities of the microinverter industry, unveiling crucial components and cost distribution to uncover precise business opportunities for China's supply chain. Stay tuned as we continue to explore the limitless potential of intelligent vision perception technology in the automotive industry!
