Kodi chowongolera cha solar ndi chiyani?
Wowongolera ma solar charger (womwe amadziwikanso kuti solar panel voltage regulator) ndi wowongolera yemwe amawongolera njira yolipirira ndi kutulutsa mumagetsi adzuwa.
Ntchito yayikulu ya chowongolera cha charger ndikuwongolera kuyitanitsa komwe kukuyenda kuchokera pagulu la PV kupita ku batri, kupangitsa kuti madzi aziyenda kuti asakhale okwera kwambiri kuti banki isapitirire.
Mitundu iwiri ya solar charge controller
MPPT & PWM
Zonse ziwiri za MPPT ndi PWM ndi njira zoyendetsera mphamvu zomwe zimagwiritsidwa ntchito ndi olamulira kuti aziyendetsa kayendedwe ka magetsi kuchokera ku module ya dzuwa kupita ku batri.
Ngakhale ma charger a PWM nthawi zambiri amayenera kukhala otchipa komanso kukhala ndi 75% kutembenuka, ma charger a MPPT ndi okwera mtengo kwambiri kugula, MPPT yaposachedwa imatha kukulitsa kwambiri kutembenuka mpaka 99%.
Wowongolera wa PWM kwenikweni ndi chosinthira chomwe chimalumikiza gulu la solar ku batri.Zotsatira zake ndikuti voteji ya gululo imatsitsidwa pafupi ndi mphamvu ya batri.
Wolamulira wa MPPT ndi wovuta kwambiri (komanso wokwera mtengo): adzasintha mphamvu zake zolowera kuti atenge mphamvu zambiri kuchokera ku dzuwa, ndiyeno amamasulira mphamvuzo muzofunikira zosiyana siyana za batri ndi katundu.Chifukwa chake, imachotsa ma voltages a gululo ndi mabatire, kotero kuti, mwachitsanzo, pali batire ya 12V mbali imodzi ya MPPT charge control ndi mapanelo olumikizidwa mndandanda kuti apange 36V mbali inayo.
Kusiyana pakati pa MPPT & PWM solar charge controller mu ntchito
Olamulira a PWM amagwiritsidwa ntchito makamaka pamakina ang'onoang'ono okhala ndi ntchito zosavuta komanso mphamvu zochepa.
Olamulira a MPPT amagwiritsidwa ntchito pamakina ang'onoang'ono, apakati, ndi akuluakulu a PV, ndipo olamulira a MPPT amagwiritsidwa ntchito pamakina apakati ndi akuluakulu omwe ali ndi zofunikira zambiri, monga malo opangira magetsi.
Oyang'anira apadera a MPPT amagwiritsidwa ntchito m'makina ang'onoang'ono a gridi, apaulendo, mabwato, magetsi a mumsewu, maso amagetsi, machitidwe osakanizidwa, ndi zina zotero.
Oyang'anira onse a PWM ndi MPPT angagwiritsidwe ntchito pa machitidwe a 12V 24V 48V, koma pamene madzi amadzimadzi ali apamwamba, woyang'anira MPPT ndi chisankho chabwino.
Olamulira a MPPT amathandizanso makina akuluakulu opangira magetsi omwe ali ndi magetsi a dzuwa pamndandanda, motero amakulitsa kugwiritsa ntchito ma solar panels.
Kusiyana kwa Malipiro a MPPT & PWM Solar Charger Controller
Ukadaulo wosintha ma pulse wide modulation umalipiritsa batire mokhazikika pazigawo zitatu (zochuluka, zoyandama, ndi mayamwidwe).
Tekinoloje ya MPPT ndiyotsata kwambiri ndipo imatha kuonedwa ngati kulipiritsa kwamasitepe ambiri.
Mphamvu yosinthira mphamvu ya jenereta ya MPPT ndiyokwera 30% poyerekeza ndi PWM.
PMW imaphatikizanso magawo atatu olipira:
Kulipira batch;Kuthamangitsa mayamwidwe;Kuthamangitsa zoyandama
Kumene kulipiritsa koyandama kuli komaliza mwa magawo 3 a kuchajisa, komwe kumadziwikanso kuti kuthamangitsa pang'onopang'ono, ndipo ndikuyika kwa batire yocheperako pang'ono komanso mokhazikika.
Mabatire ambiri omwe amatha kuchangidwanso amataya mphamvu atatha kuchangidwa.Izi zimachitika chifukwa chodzitulutsa.Ngati chiwongola dzanjacho chikusungidwa pamtengo wocheperako monga momwe mumadzichotsera nokha, mtengowo ukhoza kusungidwa.
MPPT ilinso ndi njira yolipirira magawo atatu, ndipo mosiyana ndi PWM, MPPT imatha kusinthanso kuyitanitsa potengera PV mikhalidwe.
Mosiyana ndi PWM, gawo lolipiritsa mochulukira lili ndi voteji yokhazikika.
Kuwala kwadzuwa kukakhala kolimba, mphamvu yotulutsa mphamvu ya cell ya PV imakwera kwambiri ndipo charging current (Voc) imatha kufika mwachangu polowera.Pambuyo pake, imayimitsa kuyitanitsa kwa MPPT ndikusinthira ku njira yolipiritsa nthawi zonse.
Kuwala kwadzuwa kukakhala kofooka ndipo kumakhala kovuta kusungitsa pakali pano, kumasinthira ku MPPT kulipiritsa.ndi kusinthana momasuka mpaka voteji kumbali ya batri ikwera kufika pa saturation voltage Ur ndipo batire imasinthira ku charger yokhazikika.
Pophatikiza kuyitanitsa kwa MPPT ndi kulipiritsa kosalekeza komanso kusintha kwadzidzidzi, mphamvu yadzuwa imatha kugwiritsidwa ntchito mokwanira.
Mapeto
Mwachidule, ndikuganiza kuti mwayi wa MPPT ndi wabwinoko, koma ma charger a PWM akufunikanso ndi anthu ena.
Kutengera zomwe mukuwona: nayi mawu anga:
Owongolera ma MPPT ndioyenera kwambiri kwa eni akatswiri kufunafuna wowongolera yemwe amatha kugwira ntchito zovuta (mphamvu zapakhomo, mphamvu za RV, mabwato, ndi magetsi omangidwa ndi grid).
Owongolera ma charger a PWM ndioyenera kugwiritsa ntchito magetsi ang'onoang'ono opanda gridi omwe safuna zina zilizonse ndipo amakhala ndi bajeti yayikulu.
Ngati mukungofuna chowongolera chosavuta komanso chachuma pamakina ang'onoang'ono owunikira, ndiye kuti owongolera a PWM ndi anu.
