Chii chinonzi solar charge controller?
A solar charge controller (inozivikanwawo se solar panel voltage regulator) inodzora iyo inogadzirisa kuchaja uye kuburitsa maitiro mu solar power system.
Basa guru remuchaji wechaji ndere kudzora ikozvino yekuchaja inoyerera kubva paPV panel kuenda kubhatiri, kuchengetedza iyo inoyerera kubva pakukwirisa kudzivirira bhatiri rebhatiri kuti risakwidzwe.
Mhando mbiri dze solar charge controller
MPPT uye PWM
Ose ari maviri MPPT nePWM inzira dzekudzora simba dzinoshandiswa nevanochaja kudzora kuyerera kwezvino kubva kune solar module kuenda kubhatiri.
Nepo majaja ePWM achiwanzodiwa kuve akachipa uye aine 75% yekutendeuka, MPPT machaja ari kudhura zvakanyanya kutenga, ichangoburwa MPPT inogona kuwedzera zvinoshamisa mwero wekutendeuka kusvika 99%.
Iyo PWM controller inonyatso chinja inobatanidza solar array nebhatiri.Mhedzisiro ndeyekuti iyo voltage yearray ichadhonzwa pasi pedyo nevoltage yebhatiri.
Iyo MPPT controller yakanyanya kuoma (uye inodhura zvakanyanya): ichagadzirisa yayo yekuisa voltage kuti itore iyo yakanyanya simba kubva kune solar array, uye wozoshandura iro simba mune zvakasiyana siyana zvinodiwa zvebhatiri uye mutoro.Nokudaro, inonyanya kubvisa mavheti emhando uye mabhatiri, kuitira kuti, semuenzaniso, kune bhatiri re12V kune rumwe rutivi rweMPPT charger controller uye mapaneru akabatanidzwa mumutsara kuti abudise 36V kune rumwe rutivi.
Musiyano uripo pakati peMPPT & PWM solar charge controllers mukushandisa
PWM controllers anonyanya kushandiswa kune madiki masisitimu ane mabasa akareruka uye mashoma masimba.
MPPT controllers inoshandiswa kune madiki, epakati, uye makuru ePV masisitimu, uye MPPT controller anoshandiswa kune epakati uye makuru masisitimu ane akawanda-functional zvinodiwa, senge zviteshi zvemagetsi.
Special MPPT controllers anoshandiswa mudiki off-grid masisitimu, makaravhani, zvikepe, marambi emumugwagwa, maziso emagetsi, mahybrid masisitimu, nezvimwe.
Ose ari maviri PWM neMPPT controller anogona kushandiswa kune 12V 24V 48V masisitimu, asi kana sisitimu wetage yakakwira, mutongi weMPPT isarudzo iri nani.
MPPT controllers inotsigirawo mahombe-high-voltage masisitimu ane solar panels munhevedzano, nekudaro kuwedzera kushandiswa kwema solar panel.
Musiyano wekuchaja weMPPT & PWM Solar Charger Controller
Pulse width modulation tekinoroji inochaja bhatiri mune yakatarwa 3-nhanho yekuchaja (yakawanda, inoyangarara, uye kunyura).
MPPT tekinoroji ndeye yepamusoro yekutevera uye inogona kutariswa kuwanda-nhanho kuchaja.
Simba rekushandura simba reMPPT jenareta iri 30% yakakwirira kana ichienzaniswa nePWM.
PMW inosanganisira 3 mazinga ekuchaja:
Batch kuchaja;Absorption kuchaja;Float kuchaja
Iko kuchaja kweyangarara ndiko kwekupedzisira kwematanho matatu ekuchaja, inozivikanwawo sekuti trickle kuchaja, uye iko kuiswa kwechitsama chechaji kubhatiri nemutengo wakaderera uye nenzira yakatsiga.
Mabhatiri mazhinji anochajwa anopera simba mushure mekunge azara.Izvi zvinokonzerwa nekuzvibvisa.Kana iyo yekuchaja ichichengetedzwa panguva imwechete yakaderera seyekuzviburitsa rating, mutero unogona kuchengetedzwa.
MPPT zvakare ine 3-nhanho yekuchaja maitiro, uye kusiyana nePWM, MPPT inokwanisa kushandura otomatiki kuchaja zvichienderana nePV mamiriro.
Kusiyana nePWM, iyo yakawanda yekuchaja chikamu ine yakagadziriswa yekuchaja voltage.
Kana chiedza chezuva chakasimba, simba rekubuda rePV cell rinowedzera zvakanyanya uye kuchaja ikozvino (Voc) inogona kukurumidza kusvika pachikumbaridzo.Mushure meizvozvo, inomisa iyo MPPT kuchaja uye chinja kune inogara iripo yekuchaja nzira.
Kana chiedza chezuva chaita kupera simba uye zvichinetsa kuchengetedza chinogara chichichaja, chinochinja kuenda kuMPPT kuchaja.uye chinja zvakasununguka kusvikira voltage padivi rebhatiri yakwira kusvika kuSaturation voltage Uri uye bhatiri rinochinja kuti rirambe richichaja.
Nekubatanidza MPPT kuchaja nekugara-ikozvino kuchaja uye otomatiki switching, simba rezuva rinogona kushandiswa zvizere.
Mhedziso
Muchidimbu, ndinofunga mukana weMPPT uri nani, asi PWM majaja ari kudiwawo nevamwe vanhu.
Kubva pane zvaunogona kuona: heino mhedziso yangu:
MPPT ma charger controllers akanyatsokodzera varidzi vehunyanzvi vachitsvaga mutongi anogona kuita mabasa anodiwa (simba repamba, simba reRV, zvikepe, uye magidhi-akasungwa magetsi emagetsi).
PWM charger controllers inonyatsokodzera zvidiki off-grid magetsi maapplication ayo asingade chero mamwe maficha uye ane hombe bhajeti.
Kana iwe uchingoda yakapusa uye ine mari yekuchaja controller kune madiki emwenje masisitimu, saka PWM controller ndeyako.
