Lub neej ntev ntawm lub zog cia hauv tsev yog feem ntau 10-15 xyoo, feem ntau nyob ntawm hom roj teeb, kev siv tus cwj pwm, thiab ib puag ncig. Lithium hlau phosphate (LiFePO₄) roj teeb yog qhov kev xaiv tseem ceeb, feem ntau khav theeb lub neej voj voog ntau dua 6000 cycles (80% DOD) thiab daim ntawv qhia hnub nyoog tshaj 10 xyoo.
Hom roj teeb txiav txim siab txog kev ua neej nyob
Lithium Iron Phosphate (LiFePO₄) Cov roj teeb: Tam sim no qhov kev teeb tsa tseem ceeb rau cov khoom siv hluav taws xob hauv tsev, nrog lub neej voj voog ntawm 4000-8000 cycles. Yog tias them thiab tso tawm ib zaug ib hnub, qhov theoretical lifespan tuaj yeem ncav cuag 10-15 xyoo. High- cov khoom kawg, xws li Penghui Energy's 100Ah thaj chaw cia tshuaj, tau ua tiav lub neej voj voog ntawm 7000 cycles (kwv yees li 13.5 xyoo).
Ternary Lithium roj teeb: luv luv lifespan, kwv yees li 5-8 xyoo, thiab tsis zoo thermal stability; tsis tshua siv nyob rau hauv cov chaw nyob.
Lead-acid roj teeb: Lub neej voj voog tsuas yog nyob ib ncig ntawm 500 lub voj voog, tsawg dua 5 xyoos, thiab tus nqi siab dua lithium roj teeb; tam sim no lawv yeej tsis siv lawm.
Lifespan Matching ntawm Lwm Qhov System Cheebtsam
Inverter: Lifespan kwv yees li 10 xyoo, yuav tsum tau hloov lub sijhawm nruab nrab -, raug nqi kwv yees li 3,000-8,000 RMB;
BMS system: Lifespan sib npaug ntawm cov roj teeb; siab -kawg systems txhawb kev saib xyuas tej thaj chaw deb thiab nquag ntsuas;
Zuag qhia tag nrho cov txheej txheem tsim: Photovoltaic modules muaj lub neej ntev ntawm 25-30 xyoo, txhawb nqa 2-3 lub roj teeb hloov, ua rau muaj txiaj ntsig zoo dua - lub sijhawm cov txiaj ntsig.
