Blok AC ialah produk penyimpanan tenaga bateri bersepadu sepenuhnya yang menggabungkan modul bateri, BMS, pengurusan terma dan PCS (sistem penukaran kuasa) dalam satu unit. Tidak seperti blok DC yang memerlukan penukar luaran, blok AC membekalkan arus ulang-alik serasi grid secara terus. Bagi pasukan perolehan, seni bina semua-dalam-satu ini memudahkan penyepaduan sistem, mengurangkan bilangan hubungan pembekal dan mengurangkan kerumitan BoP.
Blok AC paling kerap digunakan dalam aplikasi C&I dan projek skala utiliti bersaiz kecil, di mana kesederhanaan dan pentauliahan pantas diutamakan. Untuk projek besar, perolehan berasingan blok DC dan PCS menawarkan lebih fleksibiliti seni bina dan kedudukan perundingan yang lebih baik.
Spesifikasi utama
Apa yang perlu dibandingkan semasa menilai blok AC
Semasa menyenarai pendek untuk projek BESS, berikut ialah spesifikasi teknikal utama yang biasanya dinilai oleh syarikat EPC, pemaju dan pengintegrasi sistem:
Kadar C
0.25C – 1C
Menentukan kuasa maksimum cas/nyahcas berbanding kapasiti. Kebanyakan blok AC direka untuk 0.5C, mengimbangi prestasi dan jangka hayat.
Kapasiti tenaga
215 kWh – 10 MWh
Blok AC meliputi julat luas — daripada unit C&I (215 kWh) hingga kontena skala utiliti (10 MWh). Saiz optimum bergantung pada aplikasi dan seni bina sistem.
Kimia
LFP dominan
LFP ialah kimia standard untuk blok AC kerana profil keselamatan dan jangka hayat kitarannya. Sesetengah produk C&I menggunakan NMC apabila ketumpatan tenaga lebih tinggi diperlukan.
Kecekapan kitaran penuh
85 – 92%
Kecekapan diukur pada bahagian AC, termasuk kerugian PCS. Biasanya sedikit lebih rendah daripada sistem blok DC + PCS berasingan, kerana PCS bersepadu tidak sentiasa beroperasi pada titik optimumnya.
Kaedah penyejukan
Cecair atau udara
Blok AC skala utiliti lebih besar semakin menggunakan penyejukan cecair. Unit C&I lebih kecil biasanya menggunakan penyejukan udara.
Pensijilan
UL 9540A, IEC 62619
Pensijilan asas sama seperti blok DC. Dengan PCS bersepadu, blok AC juga perlu memenuhi keperluan sambungan grid (cth. garis panduan Suruhanjaya Tenaga) di peringkat sistem.
Soalan lazim

Apakah perbezaan antara blok AC dan blok DC?
Blok AC menyepadukan bateri dan PCS dalam satu unit dan membekalkan arus ulang-alik secara terus. Blok DC mengandungi hanya bateri, BMS dan pengurusan terma — memerlukan PCS luaran berasingan untuk sambungan grid. Blok AC memudahkan penyepaduan; blok DC menawarkan lebih fleksibiliti seni bina.
Bilakah perlu memilih blok AC berbanding blok DC?
Blok AC amat sesuai untuk aplikasi C&I, projek skala utiliti bersaiz kecil dan situasi di mana pentauliahan pantas, kurang kerumitan pembekal dan BoP minimum lebih penting daripada fleksibiliti seni bina penuh. Untuk projek skala utiliti besar (50+ MWh), kebanyakan pemaju lebih memilih blok DC dengan PCS berasingan untuk mengoptimumkan perolehan dan reka bentuk sistem secara bebas.
Apakah pensijilan yang diperlukan untuk blok AC?
Blok AC memerlukan pensijilan asas sama seperti blok DC (UL 9540A, IEC 62619) serta akreditasi tambahan untuk PCS bersepadu, termasuk pematuhan kod grid (garis panduan Suruhanjaya Tenaga, standard TNB) dan keselamatan elektronik kuasa (IEC 62477). Oleh kerana blok AC ialah unit bersepadu sepenuhnya, ujian sistem mesti meliputi interaksi semua komponen.
Berapakah julat kapasiti biasa blok AC?
Blok AC berjulat daripada kira-kira 215 kWh (unit C&I padat) hingga melebihi 10 MWh (produk skala utiliti dalam kontena). Kebanyakan blok AC C&I berada antara 200 kWh dan 1 MWh, manakala varian skala utiliti biasanya menawarkan 3–10 MWh setiap unit. Pilihan bergantung pada saiz projek, kekangan tapak dan seni bina sistem yang dikehendaki.
