進(jìn)入平穩階段的歐美微逆市場(chǎng)，在未來(lái)仍是全球最大的主戰區。

相關(guān)機構預測，2021-2025年全球微逆的出貨量復合增速達到80%。未來(lái)7年，歐洲將產(chǎn)生1.3億臺微逆的市場(chǎng)缺口，擴張至全球范圍，這一數值預計將超過(guò)4億臺。

按照目前微逆產(chǎn)品平均市場(chǎng)單價(jià)為2000~3000元計算，又一個(gè)細分的萬(wàn)億賽道即將形成。處于這個(gè)時(shí)代風(fēng)口，中國微逆企業(yè)正在紛紛以創(chuàng )新和變革走向世界。

“按接單情況估算，我們預計明年微逆出貨量為50萬(wàn)~100萬(wàn)臺。”天技新能源董事長(cháng)趙鵬表示，微逆的市場(chǎng)增長(cháng)未來(lái)仍會(huì )處于快車(chē)道，但更考驗產(chǎn)品的安全性、穩定性及實(shí)用性等核心競爭力。

趙鵬進(jìn)一步介紹說(shuō)，由于氣候原因，戶(hù)外電網(wǎng)很不可控，所以微逆產(chǎn)品更需要匹配當地電網(wǎng)、居民的消費習慣和用電情況。

作為一家勢頭強勁的新興逆變器企業(yè)，天技新能源在眾多國家和地區都有代理商，銷(xiāo)售和服務(wù)渠道體系遍布歐洲、美國、日本、東南亞等地區。

打造可以做儲能的微逆

不可控的戶(hù)外場(chǎng)景，不同電網(wǎng)的電壓、頻率、負荷，都導致用電需求的波動(dòng)。

當微逆擁有儲能功能時(shí)，可以實(shí)現模塊化儲能，在電網(wǎng)異常時(shí)可以切換到離網(wǎng)供電，釋放存儲的電能以繼續供電。因此，配備儲能功能的微逆成為市場(chǎng)上的必然需求。

作為天技集團旗下控股企業(yè)之一，天技新能源成立于2022年。公司距今成立時(shí)間不長(cháng)，但技術(shù)上創(chuàng )新不斷，公司成立之初，通過(guò)分析微逆的使用場(chǎng)景，規劃了微逆產(chǎn)品的發(fā)展方向：主要做并離網(wǎng)、儲能、AC耦合，針對應用市場(chǎng)中的普通家庭市場(chǎng)。

天技新能源第一代微逆產(chǎn)品，不僅可以應用到普通并網(wǎng)系統中，同時(shí)還針對便攜電源的功能性進(jìn)行拓展，搭配便攜系統使用，解決便攜系統并網(wǎng)售電問(wèn)題；另外在家庭儲能應用中，可以滿(mǎn)足零饋電功能、UPS功能，并可以實(shí)現離網(wǎng)并機，有效解決電網(wǎng)不穩定的問(wèn)題，實(shí)現余電存儲，光伏自發(fā)自用。更進(jìn)一步因其較高的防護等級IP67和25年的設計壽命，所以作為房車(chē)、游艇的離網(wǎng)電源系統也是非常適合的，以及其它類(lèi)似的較為惡劣環(huán)境的離網(wǎng)工作需求。

趙鵬在采訪(fǎng)中也多次對潮電智庫表明，微逆行業(yè)的多年經(jīng)驗型人才，對公司至關(guān)重要。

天技新能源的核心研發(fā)團隊都有15年以上的逆變器工作經(jīng)驗，制造現場(chǎng)管理者均有10年以上的生產(chǎn)管理經(jīng)驗。團隊成員根據海外地區不同的氣候和獨特環(huán)境，進(jìn)行大量測試和收集數據，采用專(zhuān)利級別的全球首創(chuàng )拓撲結構，逐漸為醫院、學(xué)校、加油站等特殊具體場(chǎng)景打造專(zhuān)屬微逆。

主攻家庭型并離網(wǎng)微逆

實(shí)現離網(wǎng)功能的微逆，技術(shù)門(mén)檻更高。

天技新能源銷(xiāo)售總監李文科在“2023年全球逆變器趨勢峰會(huì )暨年度頒獎典禮”現場(chǎng)表示，便攜電源下一代中有代表性的逆變器，一定是并離網(wǎng)微逆。

公司董事長(cháng)趙鵬也和潮電智庫的對話(huà)中強調了天技新能源微逆產(chǎn)品的離網(wǎng)優(yōu)勢。

天技新能源的微逆產(chǎn)品，根據電網(wǎng)和負載的情況自動(dòng)切換并網(wǎng)和離網(wǎng)兩種工作模式。在電網(wǎng)正常時(shí)實(shí)現自發(fā)自用、余電上網(wǎng)；在電網(wǎng)停電時(shí)，自動(dòng)切換為離網(wǎng)模式，與蓄電池和負載組成一個(gè)獨立的微電網(wǎng)，保證負載的正常運行。

相比Enphase通過(guò)三級能量轉換AC耦合實(shí)現儲能，天技新能源團隊通過(guò)兩級能量轉換DC耦合來(lái)實(shí)現光伏儲能功能，把能效提得更高，性?xún)r(jià)比更高。 

同時(shí)針對家庭微型并離網(wǎng)儲能需求，天技新能源提供智能的監控系統和運維平臺，為現代家庭實(shí)現一站式智能化光儲方案。

天技新能源第二代微逆體積小、散熱、防護等級高，內置了并離網(wǎng)切換功能，可以直接進(jìn)行并離網(wǎng)切換，并內置MPPT的控制器。此款微逆可以把逆變器直接內置到便攜電源、家庭儲能單元，實(shí)現雙向逆變，適合有峰谷電價(jià)地區使用，幫助普通家庭用戶(hù)實(shí)現小功率削峰填谷用電需求，節約用電開(kāi)支。

目前天技新能源Tribune系列EMS控制器，集成了(MPPT+交流)電池充電器和能源管理功能。它與天技新能源Tiger系列微逆變器一起創(chuàng )建家庭太陽(yáng)能微儲能系統，最大輸出功率可達4KW。

同時(shí)EMS控制器采用光伏模擬器的特殊電路設計，可以搭配多種品牌逆變器使用，在家庭負載很小的情況下實(shí)現功率可控，做到完全光伏發(fā)電自發(fā)自用，節約開(kāi)銷(xiāo)。這款控制器將在本月步入市場(chǎng)。

未來(lái)，公司也計劃打造3-4KW的大功率微逆出口于歐洲市場(chǎng)。
