進(jìn)入平穩(wěn)階段的歐美微逆市場(chǎng)，在未來(lái)仍是全球最大的主戰(zhàn)區(qū)。
相關(guān)機(jī)構(gòu)預(yù)測(cè)，2021-2025年全球微逆的出貨量復(fù)合增速達(dá)到80%。未來(lái)7年，歐洲將產(chǎn)生1.3億臺(tái)微逆的市場(chǎng)缺口，擴(kuò)張至全球范圍，這一數(shù)值預(yù)計(jì)將超過(guò)4億臺(tái)。
按照目前微逆產(chǎn)品平均市場(chǎng)單價(jià)為2000~3000元計(jì)算，又一個(gè)細(xì)分的萬(wàn)億賽道即將形成。處于這個(gè)時(shí)代風(fēng)口，中國(guó)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(yù)計(jì)明年微逆出貨量為50萬(wàn)~100萬(wàn)臺(tái)。”天技新能源董事長(zhǎng)趙鵬表示，微逆的市場(chǎng)增長(zhǎng)未來(lái)仍會(huì)處于快車道，但更考驗(yàn)產(chǎn)品的安全性、穩(wěn)定性及實(shí)用性等核心競(jìng)爭(zhēng)力。
趙鵬進(jìn)一步介紹說(shuō)，由于氣候原因，戶外電網(wǎng)很不可控，所以微逆產(chǎn)品更需要匹配當(dāng)?shù)仉娋W(wǎng)、居民的消費(fèi)習(xí)慣和用電情況。
作為一家勢(shì)頭強(qiáng)勁的新興逆變器企業(yè)，天技新能源在眾多國(guó)家和地區(qū)都有代理商，銷售和服務(wù)渠道體系遍布?xì)W洲、美國(guó)、日本、東南亞等地區(qū)。
打造可以做儲(chǔ)能的微逆
不可控的戶外場(chǎng)景，不同電網(wǎng)的電壓、頻率、負(fù)荷，都導(dǎo)致用電需求的波動(dòng)。
當(dāng)微逆擁有儲(chǔ)能功能時(shí)，可以實(shí)現(xiàn)模塊化儲(chǔ)能，在電網(wǎng)異常時(shí)可以切換到離網(wǎng)供電，釋放存儲(chǔ)的電能以繼續(xù)供電。因此，配備儲(chǔ)能功能的微逆成為市場(chǎng)上的必然需求。
作為天技集團(tuán)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(zhǎng)，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(guī)劃了微逆產(chǎn)品的發(fā)展方向：主要做并離網(wǎng)、儲(chǔ)能、AC耦合，針對(duì)應(yīng)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(yīng)用到普通并網(wǎng)系統(tǒng)中，同時(shí)還針對(duì)便攜電源的功能性進(jìn)行拓展，搭配便攜系統(tǒng)使用，解決便攜系統(tǒng)并網(wǎng)售電問(wèn)題；另外在家庭儲(chǔ)能應(yīng)用中，可以滿足零饋電功能、UPS功能，并可以實(shí)現(xiàn)離網(wǎng)并機(jī)，有效解決電網(wǎng)不穩(wěn)定的問(wèn)題，實(shí)現(xiàn)余電存儲(chǔ)，光伏自發(fā)自用。更進(jìn)一步因其較高的防護(hù)等級(jí)IP67和25年的設(shè)計(jì)壽命，所以作為房車、游艇的離網(wǎng)電源系統(tǒng)也是非常適合的，以及其它類似的較為惡劣環(huán)境的離網(wǎng)工作需求。
趙鵬在采訪中也多次對(duì)潮電智庫(kù)表明，微逆行業(yè)的多年經(jīng)驗(yàn)型人才，對(duì)公司至關(guān)重要。
天技新能源的核心研發(fā)團(tuán)隊(duì)都有15年以上的逆變器工作經(jīng)驗(yàn)，制造現(xiàn)場(chǎng)管理者均有10年以上的生產(chǎn)管理經(jīng)驗(yàn)。團(tuán)隊(duì)成員根據(jù)海外地區(qū)不同的氣候和獨(dú)特環(huán)境，進(jìn)行大量測(cè)試和收集數(shù)據(jù)，采用專利級(jí)別的全球首創(chuàng)拓?fù)浣Y(jié)構(gòu)，逐漸為醫(yī)院、學(xué)校、加油站等特殊具體場(chǎng)景打造專屬微逆。
主攻家庭型并離網(wǎng)微逆
實(shí)現(xiàn)離網(wǎng)功能的微逆，技術(shù)門檻更高。
天技新能源銷售總監(jiān)李文科在“2023年全球逆變器趨勢(shì)峰會(huì)暨年度頒獎(jiǎng)典禮”現(xiàn)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(zhǎng)趙鵬也和潮電智庫(kù)的對(duì)話中強(qiáng)調(diào)了天技新能源微逆產(chǎn)品的離網(wǎng)優(yōu)勢(shì)。
天技新能源的微逆產(chǎn)品，根據(jù)電網(wǎng)和負(fù)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(xiàn)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(fù)載組成一個(gè)獨(dú)立的微電網(wǎng)，保證負(fù)載的正常運(yùn)行。
相比Enphase通過(guò)三級(jí)能量轉(zhuǎn)換AC耦合實(shí)現(xiàn)儲(chǔ)能，天技新能源團(tuán)隊(duì)通過(guò)兩級(jí)能量轉(zhuǎn)換DC耦合來(lái)實(shí)現(xiàn)光伏儲(chǔ)能功能，把能效提得更高，性價(jià)比更高。
同時(shí)針對(duì)家庭微型并離網(wǎng)儲(chǔ)能需求，天技新能源提供智能的監(jiān)控系統(tǒng)和運(yùn)維平臺(tái)，為現(xiàn)代家庭實(shí)現(xiàn)一站式智能化光儲(chǔ)方案。
天技新能源第二代微逆體積小、散熱、防護(hù)等級(jí)高，內(nèi)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(nèi)置MPPT的控制器。此款微逆可以把逆變器直接內(nèi)置到便攜電源、家庭儲(chǔ)能單元，實(shí)現(xiàn)雙向逆變，適合有峰谷電價(jià)地區(qū)使用，幫助普通家庭用戶實(shí)現(xiàn)小功率削峰填谷用電需求，節(jié)約用電開支。
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(chǔ)能系統(tǒng)，最大輸出功率可達(dá)4KW。
