Ang AC block ay isang fully integrated battery energy storage product na pinagsasama ang mga battery module, BMS, thermal management, at PCS (power conversion system) sa isang unit. Hindi katulad ng mga DC block na nangangailangan ng external converter, ang AC block ay direktang nagbibigay ng grid-compatible AC. Para sa mga procurement team, ang all-in-one architecture na ito ay pinapasimple ang system integration, binabawasan ang bilang ng supplier relationship, at binabawasan ang BoP complexity.
Ang mga AC block ay mas madalas gamitin sa C&I application at mas maliliit na utility-scale project, kung saan ang simplicity at mabilis na commissioning ang priority. Para sa malalaking project, ang hiwalay na procurement ng DC block at PCS ay nagbibigay ng mas malaking architectural flexibility at mas magandang negotiating position.
Mga pangunahing specification
Ano ang i-compare kapag nag-e-evaluate ng mga AC block
Kapag nagso-shortlist ng para sa isang BESS project, ito ang mga pangunahing technical specification na karaniwang ine-evaluate ng mga EPC company, developer, at system integrator:
C-rate
0.25C – 1C
Tumutukoy sa maximum na charge/discharge power kaugnay ng capacity. Karamihan sa mga AC block ay dinisenyo para sa 0.5C, na nagbabalanse ng performance at cycle life.
Energy capacity
215 kWh – 10 MWh
Malawak ang saklaw ng mga AC block — mula sa mga C&I unit (215 kWh) hanggang utility-scale container (10 MWh). Ang optimal na size ay depende sa application at system architecture.
Chemistry
LFP nangingibabaw
Ang LFP ang standard na chemistry para sa mga AC block dahil sa safety profile at cycle life nito. Ilang C&I product ang gumagamit ng NMC kapag kailangan ng mas mataas na energy density.
Round-trip efficiency
85 – 92 %
Efficiency na sinusukat sa AC side, kasama ang PCS loss. Karaniwang bahagyang mas mababa kaysa sa hiwalay na DC block + PCS system, dahil ang integrated PCS ay hindi laging nag-o-operate sa optimal na operating point.
Cooling method
Liquid o air
Ang mas malalaking utility-scale AC block ay lalong gumagamit ng liquid cooling. Ang mas maliliit na C&I unit ay karaniwang gumagamit ng air cooling.
Mga Certification
UL 9540A, IEC 62619
Pareho ang base certification sa mga DC block. Dahil may integrated PCS ang AC block, kailangan din nitong matugunan ang grid connection requirement (hal. Philippine Grid Code ng NGCP/ERC) sa system level.
Mga madalas na tanong
Mga madalas na tanong
Ano ang pagkakaiba ng AC block at DC block?
Ang AC block ay nag-i-integrate ng battery at PCS sa isang unit at direktang nagbibigay ng alternating current. Ang DC block ay naglalaman lamang ng battery, BMS, at thermal management — nangangailangan ng hiwalay na external PCS para sa grid connection. Pinapasimple ng mga AC block ang integration; nagbibigay naman ang mga DC block ng mas malaking architectural flexibility.
Kailan dapat pumili ng AC block kaysa DC block?
Ang mga AC block ay partikular na angkop para sa C&I application, mas maliliit na utility-scale project, at mga sitwasyon kung saan ang mabilis na commissioning, mas kaunting supplier complexity, at minimal BoP ay mas mahalaga kaysa buong architectural flexibility. Para sa malalaking utility-scale project (50+ MWh), mas pinipili ng karamihan ng developer ang DC block na may hiwalay na PCS para independiyenteng ma-optimize ang procurement at system design.
Anong certification ang kailangan ng AC block?
Ang mga AC block ay nangangailangan ng parehong base certification tulad ng mga DC block (UL 9540A, IEC 62619) kasama ang karagdagang accreditation para sa integrated PCS, kabilang ang grid code compliance (Philippine Grid Code ng NGCP/ERC) at power electronics safety (IEC 62477). Dahil ang AC block ay isang fully integrated unit, ang system testing ay kailangang sumasaklaw sa interaction ng lahat ng component.
Ano ang karaniwang capacity range ng mga AC block?
Ang mga AC block ay mula sa humigit-kumulang 215 kWh (compact C&I unit) hanggang higit sa 10 MWh (utility-scale container product). Karamihan ng C&I AC block ay nasa pagitan ng 200 kWh at 1 MWh, samantalang ang utility-scale variant ay karaniwang nag-aalok ng 3–10 MWh bawat unit. Ang pagpili ay depende sa project size, site constraint, at gustong system architecture.
