Inkqubo yokugcina amandla elanga ye-photovoltaic yeyona ndlela isetyenziswa kakhulu yokugcina amandla kwiimarike. Kwiinkqubo zokugcina amandla e-photovoltaic ngaphandle kwegridi, iipakethi zebhetri ze-lithium zizinto ezibalulekileyo. Ke indlela yokuthelekisa ipakethi yebhetri ye-lithium? Yabelana ngoku namhlanje.

Inkqubo yokugcina amandla eSolar photovoltaic--ukukhanya kwesitrato solar

1. Okokuqala, misela uchungechunge lweqonga le-voltage yenkqubo yokugcina amandla elanga ye-photovoltaic
   Okwangoku, iiplatifti ezininzi ze-photovoltaic zokugcinwa kwamandla e-voltage ziyi-12V series, ngokukodwa iinkqubo zokugcina amandla e-off-grid, ezifana nezibane zesitalato zelanga, izixhobo zokubeka iliso zelanga zokugcinwa kwamandla, izixhobo ezincinci zokugcina amandla e-photovoltaic eziphathwayo, njalo njalo. Uninzi lweenkqubo zokugcina amandla e-photovoltaic elanga usebenzisa i-12V uchungechunge lweenkqubo zokugcina amandla kunye namandla angaphantsi kwe-300W.

Ezinye iinkqubo zokugcina amandla e-photovoltaic eziphantsi kwe-voltage zibandakanya: uchungechunge lwe-3V, njengezibane eziphuthumayo zelanga, iimpawu ezincinci zelanga, njl.; Uthotho lwe-6V, njengezibane zelanga, iisimboli zelanga, njl.; Uchungechunge lwe-9V yeenkqubo zokugcina amandla e-photovoltaic nazo zininzi, phakathi kwe-6V kunye ne-12V, ezinye izibane zesitrato zelanga nazo zine-9V. Iinkqubo ze-solar photovoltaic zisebenzisa i-9V, i-6V, kunye ne-3V uchungechunge ziinkqubo ezincinci zokugcina amandla ngaphantsi kwe-30W.

ukukhanya kwelawn yelanga

Ezinye iinkqubo zokugcina amandla ombane we-photovoltaic eziphezulu zibandakanya: uchungechunge lwe-24V, njengebala lebhola lokukhanya kwelanga, i-medium-size solar photovoltaic iinkqubo zokugcina amandla eziphathekayo, amandla ezi nkqubo zokugcina amandla zikhulu, malunga ne-500W; kukho i-36V, i-48V i-series ye-Photovoltaic yokugcina amandla ombane, ugxininiso luya kubaluleka ngakumbi. Ngaphezulu kwe-1000W, njengeenkqubo zokugcina amandla e-photovoltaic yasekhaya, amandla okugcina amandla angaphandle aphathekayo, njl., Amandla aya kufikelela malunga ne-5000W; kunjalo, kukho iinkqubo ezinkulu zokugcina amandla e-photovoltaic, i-voltage iya kufikelela kwi-96V, i-192V series, ezi nkqubo zokugcina amandla ombane we-photovoltaic ngokukodwa zizikhululo zamandla okugcina amandla e-photovoltaic.

2. Indlela yokuthelekisa umthamo webhetri yelithium
   Ukuthatha uchungechunge lwe-12V kunye nebhetshi enkulu kwimarike njengomzekelo kwiimveliso zobuchwepheshe, siya kubelana ngendlela ehambelanayo yeepakethi zebhetri ze-lithium.

Okwangoku, kukho imiba emibini ehambelanayo; enye lixesha lonikezelo lwamandla lwenkqubo yokugcina amandla ukubala umdlalo; enye yiphaneli yelanga kunye nexesha lokutshaja kwelanga lokutshatisa.

Masithethe ngokuthelekisa umthamo wepakethi yebhetri ye-lithium ngokwexesha lonikezelo lwamandla.

Ngokomzekelo, uchungechunge lwe-12V lwenkqubo yokugcina amandla e-photovoltaic kunye ne-50W yamandla okukhanya kwesitalato selanga kufuneka sibe neeyure ze-10 zokukhanya imihla ngemihla. Kubalulekile ukuqwalasela ukuba ayinakuhlawulisa ngeentsuku ezintathu zemvula.

Emva koko umthamo webhetri ye-lithium unokuba yi-50W10hIintsuku ezi-3/12V=125Ah. Siyakwazi ukufanisa i-12V125Ah lithium ibhetri pack ukuxhasa le nkqubo yokugcina amandla e-photovoltaic. Indlela yokubala ihlula inani elipheleleyo leeyure ze-watt ezifunekayo kwisibane sesitalato nge-voltage yesikhulumi. Ukuba ayinakuhlawulisa ngeentsuku ezinamafu kunye nemvula, kuyimfuneko ukuqwalasela ukunyusa umthamo ohambelanayo osecaleni.

Ilizwe lokukhanya kweSolar Street

Makhe sithethe ngendlela yokulinganisa umthamo wepakethi yebhetri ye-lithium ngokwepaneli yelanga kunye nexesha lokutshaja kwelanga.

Ngokomzekelo, kusekho inkqubo ye-12V ye-photovoltaic yokugcina amandla. Amandla okukhutshwa kwepaneli yelanga yi-100W, kwaye ixesha elaneleyo lokukhanya kwelanga lokutshaja ziiyure ezi-5 ngosuku. Inkqubo yokugcina amandla kufuneka ihlawule ibhetri ye-lithium ngaphakathi kosuku olunye ngokupheleleyo. Indlela yokuthelekisa umthamo wepakethi yebhetri ye-lithium?

Indlela yokubala yi-100W*5h/12V=41.7Ah. Oko kukuthi, kule nkqubo yokugcina amandla e-photovoltaic, sinokufanisa i-12V41.7Ah ibhetri ye-lithium pack.

inkqubo yokugcina amandla elanga

Le ndlela yokubala ingentla ayihoyi ilahleko. Iyakwazi ukubala inkqubo yokusetyenziswa kwangempela ngokwezinga elithile lokuguqulwa kwelahleko. Kukho neentlobo ezahlukeneyo zeepakethi zebhetri ye-lithium, kwaye i-voltage yeqonga ehlanganisiweyo nayo yahlukile. Umzekelo, inkqubo ye-12V ye-lithium ibhetri ipakethe isebenzisa ibhetri ye-lithium ye-ternary kwaye idinga uchungechunge oluthathu oluxhunyiwe. I-voltage yeqonga iya kuba yi-3.6VImitya emi-3=10.8V; Ipakethi yebhetri ye-lithium iron phosphate iya kusebenzisa i-4 kuthotho ukuze iqonga lombane libe yi-3.2V4=12.8V.

Ngoko ke, indlela yokubala echanekileyo kufuneka ibalwe ngokongeza ukulahleka kwenkqubo yemveliso ethile kunye ne-voltage ehambelanayo yeqonga elithile, eliya kuba lichaneka ngakumbi.

Isitishi soMbane esiphathekayo

ISikhululo soMbane esiPhathwayo sisixhobo esiphathwayo, esinebhetri esinokubonelela ngombane kwizixhobo zombane ezahlukeneyo. Ngokwesiqhelo iqulathe ibhetri kunye ne-inverter, eguqula amandla agciniweyo eDC abe ngamandla e-AC anokuthi asetyenziswe zizixhobo zasekhaya ezininzi kunye nombane. Izikhululo zamandla eziphathwayo zihlala zisetyenziswa njengomthombo wamandla ogcinayo wokukhempisha, imisitho yangaphandle, kunye neemeko zonxunguphalo.

Izikhululo zamandla eziphathwayo zidla ngokuhlawuliswa kusetyenziswa ioutlet eseludongeni okanye ipaneli yesola, kwaye zinokuthwalwa lula okanye zithuthwe zisiwe kwiindawo ezahlukeneyo. Zifumaneka kuluhlu lweesayizi kunye neziphumo zamandla, kunye neemodeli ezinkulu ezikwazi ukunika amandla izixhobo ezininzi ngexesha elinye. Ezinye izikhululo zamandla eziphathwayo nazo zineempawu ezongezelelweyo, ezinje ngezibuko le-USB lezixhobo zokutshaja, okanye izibane ze-LED ezakhelwe ngaphakathi zokukhanyisa.
