Ob txoj kev daws teeb meem no txawv heev ntawm cov txheej txheem kev teeb tsa, kev ua kom lub cev muaj zog, tus nqi tu, thiab cov xwm txheej siv tau. Kev nkag siab txog lawv cov yam ntxwv thiab qhov zoo thiab qhov tsis zoo tuaj yeem pab tsis tau tsuas yog pab cov neeg siv xaiv lub zog cia kev daws teeb meem uas zoo dua rau lawv tsev neeg cov kev xav tau tab sis kuj tseem txhim kho cov txheej txheem rov qab los ntawm kev nqis peev. Kab lus no yuav txheeb xyuas qhov sib txawv ntawmintegrated thiab modular nyob hauv lub zog cia roj teeblos ntawm ntau qhov kev pom los pab koj ua qhov kev xaiv paub ntau ntxiv.

 

 

Lub ntsiab txhais

 

1. Tag nrho -nyob rau hauv -Ib Qhov Chaw Tso Hluav Taws Xob Photovoltaic: Ib lub txee sib koom ua ke nrog photovoltaic MPPT, bidirectional PCS inverter, lithium roj teeb pob, BMS, thiab ib qhoEMS zog tswj qhov system. Photovoltaics, roj teeb, thiab inverters yog tag nrho ua tau -nyob rau hauv, nrog Hoobkas-matched hardware thiab software. Nws tsuas yog yuav tsum tau sab nraud photovoltaic vaj huam sib luag, khoom siv hauv tsev, thiab daim phiaj hluav taws xob ua haujlwm. Qhov kev daws teeb meem tseem ceeb yog DC coupling.

 

2. Split-Hom Zog Cia (Sib cais PCS + Roj teeb): Ob chav nyob ywj pheej: ib lub zog bidirectional cia PCS inverter + ib qho kev ywj pheej lithium roj teeb txee. Lawv muab tso rau nyias thiab xaim nyias. Ob lub topologies muaj: DC coupling (photovoltaics ncaj qha txuas mus rau PCS DC davhlau ya nyob twg) thiab AC coupling (muaj photovoltaic inverter txuas nrog daim phiaj ua ntej txuas rau PCS). Cov Cheebtsam tuaj yeem hloov pauv thiab nthuav dav ib tus zuj zus.

 

 

 

 

Kev sib piv ntawm Core Performance, Nqi, thiab Kev Ua Haujlwm & Kev Tu

 

Sib piv Dimensions	Txhua yam -hauv-ib ESS	Cais PCS + roj teeb ywj siab
