以下沉產業鏈為根基，潮電智庫特選出逆變器行業系列明星產品進行拆解，旨在通過展現內部核心結構件及成本占比，為中國供應鏈找到更準確的商機落點。

繼陽光電源、古瑞瓦特、固德威、Enphas、錦浪科技等廠牌逆變器產品之后，本期拆解主角為上能電氣SP-320K-H。

上能電氣2011年開始推出組串式逆變器產品進軍分布式光伏，SP-320K-H是其官網上最大功率的組串式逆變器，額定輸出功率為320KW。

該產品特點為：最大效率99.02%，12路MPPT設計，適應復雜環境；支持PLC通訊，節省通訊線纜成本；支持1.5倍以上容配比，降低LCOE；MPPT最大輸入電流45A，適配大功率組件；組串級PV曲線掃描，精準定位組串故障。

該逆變器零部件大部分采用美國和日本產品，其中IGBT、MOSFET由美國安森美提供，MCU主控芯片和連接器分別由美國企業德州儀器、安費諾提供。

電感和PCB板供應分別為中國企業伊戈爾、生益電子。

散熱器和變壓器則分別由日本三洋和中國臺灣臺達電子提供。

上能電氣光伏逆變器產品主要為組串式、集中式、集散式等幾種。

目前上能電氣的組串式逆變器可提供8~350kW全功率段產品，實現了較廣的功率覆蓋。采用多電平/軟開關變換技術，實現系統效率的最大化。采用超寬MPPT電壓輸入范圍設計，可實現戶用電站、工商業電站、大型地面電站等全場景應用。

光伏逆變器行業經過多年的市場競爭，已形成較為穩定、集中的市場格局。在國內，集中式地面電站主要以央國企招投標為主。

經過多年的發展，目前上能電氣在集中式地面電站的招投標中穩居前三。與此同時，公司重視海外市場的發展，目前在完成印度、東南亞、中東、歐洲等地面光伏電站市場業務布局的基礎上，繼續增加其他業務及細分市場的海外拓展。

7月19日晚間，上能電氣披露2023年半年報。報告期內實現營收21.77億元，同比增長416.58％；凈利潤1.35億元，同比增長488.54%。

Supply chain analysis of the SINENG SP-320K-H, the maximum power inverter

Built on the foundation of the sinking industrial chain, ChaoDian industry research institute analysis the flagship products from the inverter industry. This endeavor aims to showcase internal core structural components and cost breakdowns, pinpointing more precise business opportunities for China's supply chain.

Following brands like Sungrow, GoodWe, Growatt, Enphase, and Ginlong Technologies, this edition's focus is on the SINENG Electric SP-320K-H inverter.

Since 2011,SINENG Electric has ventured into the distributed photovoltaic sector with its string inverters. The SP-320K-H is the flagship model on their official website, boasting a rated output power of 320KW.

Key features of this product include: an exceptional efficiency of up to 99.02%, a 12-MPPT design for adapting to complex environments, support for PLC communication to reduce cable costs, compatibility with over 1.5 times rated PV array capacity ratio to lower LCOE, a maximum MPPT input current of 45A to accommodate high-power modules, and string-level PV curve scanning for pinpointing string faults accurately.

Most of the components for this inverter are sourced from the USA and Japan. IGBT and MOSFET components are supplied by the US-based ON Semiconductor, while the MCU control chip and connectors are provided by Texas Instruments and Amphenol, both American companies.

Inductors and PCB boards are sourced from Chinese firms EAGLERISE and Shengyi Electronics, respectively. Heat sinks and transformers come from Japanese firm Sanyo and Taiwanese manufacturer Delta Electronics.

SINENG's photovoltaic inverter portfolio primarily consists of string, central, and distributed inverters. Their string inverters range from 8KW to 350KW, offering a broad power coverage. Employing multi-level/soft-switching technology maximizes system efficiency. An ultra-wide MPPT voltage input range caters to residential, commercial, and large-scale ground station applications.

After years of market competition, the photovoltaic inverter industry has formed a relatively stable, concentrated market structure. In China, the central ground station projects are primarily tendered by central state-owned enterprises.

Following years of development,SINENG Electric now consistently ranks in the top three for tenders of central ground station projects. Simultaneously, the company prioritizes international market expansion. They've already established their presence in ground station markets in India, Southeast Asia, the Middle East, and Europe, while continuing to extend their reach to other overseas markets and segments.

On the evening of July 19th,SINENG Electric released its H1 2023 interim report. They achieved a revenue of 2.177 billion RMB in the first half of the year, a staggering YoY growth of 416.58%. Net profit reached 135 million RMB, reflecting a remarkable YoY growth of 488.54%.
