Engvangin nge containerized energy storage hi standard a lo nih?
A awlsam zawngin: a awlsam zawk.
Tun hma chuan energy storage project-ah hian battery, PCS, BMS, kangmei laka invenna system, leh air conditioning te a hrana lei a ngai a, on-site integration leh commissioning atan thla thum chhung a ngai a ni. Kum tlemte kalta khan kan project pakhatah chuan supplier panga nena interface protocol inremtirna tur chauha meeting sawmhnih chuang kan nei a.
Tunah? Feet 40-foot container, a tlem berah 5MWh pe chhuak thei chu a hmunah an chawi sang a, an inzawm khawm a, kar khat chhungin commission a ni. Client-te hian hun leh tha an humhim a, EPC contractor-te chuan hun an humhim a, bank-te pawhin an duh em em-standardized products tih awmzia chu controllable risk tihna a ni.
Mahse, hriat tur thang a awm: Containerized storage ≠ plug-leh-play.
Nikum khan Guangdong-a project pakhatah chuan client chuan a lei hnuah hman nghal a ni ang tih a ngaihtuah a, mahse a siamtuin transformer a pek chu site specification nen a inmil lo tih a hmuchhuak a, hei vang hian thla hnih-a nghah a ngai a ni. Chuvangin, thil lei hmain grid connection parameter, site condition, leh kangmei laka invenna hlat zawng chiang taka finfiah a pawimawh hle.
Core Selection Principle: Hriselna hmasa ber, Thil dang zawng zawng pahnihna
Kum tlemte kalta khan South Korea-a energy storage power station-a kangmei chhuak chu ni thum chhung zet a kang a, RMB maktaduai 200 chuang zet hloh a ni. Chumi hnuah chuan tender document ka hmuh apiangah safety weighting chu 20% atanga 35% aia tam ah a pung ta a ni.
A awlsam zawngin: Safety hi a up to par lo a nih chuan technology tha ber pawh a tangkai lo.
Engtin nge himna hi kan teh ang? Point pathum han en teh:
