Hnub ci connectors tej zaum yuav me me, tab sis lawv yog cov uas tsis muaj peev xwm ntawm txhua lub hnub ci teeb. Lawv txoj hauj lwm? Ua kom cov hluav taws xob ntws zoo nyob nruab nrab ntawm lub hnub ci vaj huam sib luag, lub zog hluav taws xob, thiab cov roj teeb- qhov tseem ceeb, lawv yog "txoj kev" uas hloov lub hnub ci mus rau lub zog siv tau. Txawm hais tias koj tab tom tham txog ob peb lub hnub ci vaj huam sib luag ntawm lub ru tsev lossis thaj chaw loj ntawm cov vaj huam sib luag uas muaj zog hauv lub nroog, cov khoom sib txuas no nyob txhua qhov chaw. Cia peb kawm seb lawv ua haujlwm li cas hauv lub neej tiag tiag.
Txuas Hnub Ci Vaj Huam Sib Luag: Tsim "Power Chain"
Ib lub hnub ci vaj huam sib luag tsis ua kom muaj hluav taws xob txaus lossis tam sim no los khiav koj lub tsev lossis pub lub zog rau daim phiaj. Qhov ntawd yog qhov uas cov khoom sib txuas tuaj rau hauv -lawv cia koj txuas ntau lub vaj huam sib luag ua ke (txawm yog nyob rau hauv "chain" lossis sab - los ntawm -sab) los ua kom muaj zog "zog array."
Chaining panels (series kev sib txuas): Qhov no yog txoj hauv kev zoo tshaj plaws los txhawb qhov voltage. Xav txog tias koj muaj 20 lub hnub ci vaj huam sib luag- txhua qhov tso tawm ib ncig ntawm 30V. Siv cov khoom sib txuas, koj txuas qhov zoo kawg ntawm ib lub vaj huam sib luag mus rau qhov tsis zoo ntawm qhov tom ntej, zoo li txuas cov roj teeb hauv lub teeb nyem. Thaum kawg, koj tau txais 600V tag nrho- txaus rau lub zog inverter (lub cuab yeej uas hloov hnub ci DC fais fab rau hauv AC fais fab rau koj lub tsev). Cov neeg feem coob siv "MC4 connectors" ntawm no{10}}lawv yog tus qauv kev lag luam, thiab lawv muaj ib qho kev tsim- hauv "tsis muaj rov qab ntsaws" tsim, yog li koj tsis tuaj yeem cuam tshuam cov xaim thiab tawg lub vaj huam sib luag.
Sab-los ntawm- sab vaj huam sib luag (kev sib txuas ua ke): Qee zaum koj xav tau tam sim no ntau dua es tsis txhob muaj qhov hluav taws xob ntau dua-zoo li cov roj teeb loj. Ntawm no, koj siv cov khoom sib txuas los txuas qhov zoo kawg ntawm ntau lub vaj huam sib luag ua ke, thiab qhov tsis zoo xaus ua ke. Cov khoom sib txuas no yuav tsum tau siv hluav taws xob ntau dua (feem ntau 30-60 amps) thiab ua kom tsis muaj nag thiab plua plav, vim lawv nyob nraum 24/7.
Txuas tag nrho System: Los ntawm cov vaj huam sib luag rau lub hwj chim
Hnub ci vaj huam sib luag yog qhov pib xwb-koj xav tau cov khoom sib txuas kom tau txais lub zog ntawd qhov twg nws yuav tsum mus: mus rau lub inverter, roj teeb, lossis txawm tias daim phiaj.
Panels rau inverter: Lub inverter yog "lub hlwb" uas hloov hnub ci DC fais fab rau hauv AC zog. Cov khoom sib txuas ntawm no yuav tsum tau tswj cov hluav taws xob siab (800V lossis 1500V, nyob ntawm koj lub cev) thiab poob lub zog tsawg li sai tau. Cov neeg zoo muaj nyiaj -plated cov lus qhia- qhov no ua rau "kev tiv thaiv tiv thaiv" qis (hauv qab 5mΩ, yog tias koj xav paub), yog li lub zog tsawg dua li cua sov (tsis muaj kev pheej hmoo ntawm kev kub ntxhov ntawm no!).
Inverter rau roj teeb / kab sib chaws: Yog tias koj muaj lub roj teeb (zoo li lub hnub ci hauv tsev + kev teeb tsa), cov khoom txuas txuas lub inverter rau lub roj teeb. Lawv ua hauj lwm nrog lub roj teeb "lub hlwb" (BMS) kom tsis txhob overcharging - kom koj lub roj teeb tsis puas. Yog tias koj pub lub zog ncaj nraim rau daim phiaj, cov khoom sib txuas ua ke nrog cov kab sib chaws cov qauv, thiab qee qhov tseem muaj kev tiv thaiv xob laim (tseem ceeb rau kev teeb tsa sab nraum zoov!).
Cov chaw nres tsheb loj: Qhov txuas "hluav taws xob" txuas: Hauv thaj chaw hnub ci loj (xws li suab puam fais fab nroj tsuag), koj tsis tuaj yeem xaim txhua lub vaj huam sib luag ncaj qha mus rau lub inverter - uas yuav yog qhov teeb meem. Hloov chaw, cov vaj huam sib luag tau muab faib ua arrays, thiab cov khoom sib txuas pub tag nrho cov hwj huam ntawd rau hauv "lub thawv sib txuas" (kom muab cov tam sim no). Tom qab ntawd, hnyav- cov haujlwm txuas txuas xa cov fais fab sib txuas mus rau lub inverter. Cov hlws ris lub thawv txuas no yuav tsum tau ua kom muaj cua sov siab (-40℃txog 85 degree) thiab ua haujlwm tsis ua haujlwm sab nraum zoov.
Kev sib txuas rau txhua qhov xwm txheej: Ib Qhov Loj Tsis haum Txhua
Kev teeb tsa hnub ci tsis zoo ib yam -koj lub ru tsev vaj huam sib luag xav tau cov khoom sib txuas sib txawv dua li cov nroj tsuag suab puam lossis lub vaj huam sib luag mus pw hav zoov. Nov yog qhov lawv hloov pauv li cas:
Kev teeb tsa hauv tsev / kev lag luam ru tsev: Cov vaj huam sib luag ru tsev yog qaij, thiab lawv nyob ze ntawm koj lub tsev -yog li cov khoom sib txuas yuav tsum tsis txhob muaj dej tsis zoo / plua plav (nyob IP67 lossis siab dua, txhais tau tias lawv tuaj yeem tiv nag thiab av). Rau cov ru tsev hlau (xws li nyob rau hauv warehouses), connectors feem ntau "sab-plug" style- yooj yim rau nruab rau hauv qhov chaw nruj. Lawv cov plhaub yas kuj tiv thaiv lub hnub puas tsuaj (lawv yog ua los ntawm PC + ABS yas, uas tsis tau nkig hauv lub hnub).
Cov chaw nres tsheb loj sab nraud:
Chaw nres tsheb suab puam: Xuab zeb yog yeeb ncuab ntawm no- cov khoom sib txuas muaj ob lub roj hmab ntsaws ruaj ruaj kom cov xuab zeb tawm. Lawv kuj tuav cov cua kub heev (qee tus tuaj yeem siv 125℃rau luv luv tawg) kom lawv tsis yaj.
Cov chaw dej (floating solar panels): Cov no yuav tsum tau tiv thaiv xeb -cov khoom txuas siv 316 stainless hlau cov lus qhia thiab dej- cov roj hmab tiv taus, yog li dej hauv pas dej tsis corrode lawv.
Cov chaw txias hauv roob: Cov khoom sib txuas ntawm no yuav tsum nyob twj ywm hauv qhov txias (-40 degree) yog li koj tseem tuaj yeem ntsaws / tshem tawm thaum lub caij ntuj no (tsis muaj cov yas tawg!).
Portable panels (camping/emergency power): Yog tias koj muaj daim pam solar foldable rau camping, connectors me me thiab siv tau yooj yim -xav USB-C lossis DC plugs. Lawv kuj muaj "nias rau qhib" tsim, yog li koj tsis txhob yuam kev yank lawv tawm thiab poob zog.
Cov lus qhia kom cov Connectors ua haujlwm zoo
Txawm tias qhov zoo tshaj plaws connectors xav tau kev saib xyuas me ntsis - ntawm no yog yuav ua li cas:
Xaiv qhov yog: Sib piv cov connector rau koj qhov system qhov voltage (1500V systems xav tau 1500V-rated connectors!) thiab tam sim no (mus rau 1.2x koj lub vaj huam sib luag max tam sim no). Rau sab nraum zoov, IP67 / IP68 yog qhov yuav tsum tau ua.
Nruab nws txoj cai: ntsaws rau hauv txhua txoj kev -koj yuav hnov ib "nias" thaum nws kaw. Yog tias nws tsuas yog ib nrab - ntsaws, nws yuav kub (xov xwm phem!). Tsis tas li ntawd, cia me ntsis ntxiv cable- panels nthuav dav / cog lus nyob rau hauv lub hnub, thiab nruj cables yuav rub cov connectors xoob.
Txheeb xyuas lawv tsis tu ncua: Txhua 1-2 xyoos, so cov plua plav tawm ntawm cov ntsaws ruaj ruaj, xyuas seb cov roj hmab ntsaws ruaj ruaj puas tawg, thiab sim "sib cuag tiv thaiv". Tom qab cua daj cua dub los yog cua daj cua dub, ob -kos-dej lossis xuab zeb hauv tuaj yeem ua rau lawv tawg.
Wrapping Up
Lub hnub ci txuas zoo li "cov pob qij txha" hauv lub hnub ci- tsis muaj lawv, lub zog tsis tuaj yeem ntws, thiab koj cov vaj huam sib luag tsuas yog khoom kim heev. Raws li lub hnub ci loj dua (qhov hluav taws xob ntau dua, lub zog ntau dua), cov khoom sib txuas kuj tau zoo dua - qee qhov tam sim no muaj qhov ntsuas kub los ceeb toom koj yog tias lawv kub dhau. Txawm hais tias koj siv zog rau koj lub tsev, lub nroog, lossis mus pw hav zoov, cov kev txuas me me no yog qhov ua rau lub hnub ci ua haujlwm rau koj.
