Indlela ukukhetha umlawuli ngenxa solar? Controller ukuba panel elanga kunye ngezandla zabo

Akulula xa uqeqeshelwa ukuba eminye imithombo yamandla iye yaqhubeka kangangethuba iminyaka embalwa, egubungele amacandelo ahlukeneyo. Ngaphandle nomtsalane ingqiqo energy simahla, xa kusenziwa kulula ukuba kusebenze. Kukho zombini ubunzima technical nezemali. Nakuba kunjalo, kwimeko yamandla bugwetyelwe iiprojekthi umthamo amancinci. Umzekelo, eli gosa ukuba ibhetri elanga ingasetyenziswa ukutya lwasimahla izixhobo zombane, nokuba ekhaya. Eli candelo olawula ukusebenza ibhetri, evumela kangangoko nisebenze intlawulo eyenziwe.

Yintoni na le parameters isilawuli kufuneka ziqwalaselwe?

Kwindawo yokuqala kulindeleke ukuba amandla iyonke kunye igalelo ombane kwenkqubo phantsi apho esisebenza ekhethiweyo. Oko kukuthi, izinto unikezelo samandla okanye ibhetri akayi ngaphezu inkqubo ombane yi ixabiso imveliso yangoku isixhobo yolawulo. Apho umlawuli ngenxa yeseli elanga yi ombane uyakhululwa ibhetri esekelwe ekhethiweyo. Kufuneka kwakhona kubonelelwa, kunye nesenti imajini 20 ngalinye le ombane xa kuthe eyandileyo umsebenzi elanga.

Kwakhona, eli zibalwa kwinqanaba ukuthotyelwa ukuya ombane igalelo. Eli xabiso lilawulwa ngokungqongqo kwezi meko efanayo umsebenzi radiation engaqhelekanga. Imarike for isilawuli ibhetri elanga thaca ngeendlela ezahlukeneyo, nganye kuzo ifuna iimpawu zayo ezithile wachaza novavanyo.

Ingakumbi ukhetho izilawuli PWM

Ukukhetha le hlobo isixhobo yolawulo iye indlela elula - elizayo umsebenzisi mfuneko ukuchaza kuphela elilelona parameters short ngoku wesiphaluka kumnqongo ezisetyenziswayo. Kuyimfuneko kwakhona ukunika ezithile eludinini. Umzekelo, ukuba solar generator 100 watt current stably esebenzela isalathi elifutshane langoku yesiphaluka ka 6.7 A, eli kufuneka abe rated ixabiso zangoku malunga 7.5 A.

Maxa wambi kuthathelwa ingqalelo kunye nokukhutshwa yangoku. Ingakumbi kubalulekile ukuqwalasela ukusebenza nabaqondisi ukuya umsebenzi wolawulo umthwalo. Kulo mzekelo, eli yokukhetha neebhetri elanga kwenziwa ukuze obhobhozayo yangoku ayidluli njengezifanelekileyo efanayo kwifowni wolawulo.

Features MPPT isilawuli oyikhethileyo

Olu hlobo isilawuli lukhethiwe ngokungqinelana kwingongoma nganye ngamandla. Ngoko ke, ukuba yangoku liphezulu icebo 50 A kwaye inkqubo isebenza ngokupheleleyo kunye ombane ayi-48 V, amandla isilawuli incopho malunga ongeziweyo 2900 W ezisekelwe eqinisekisa isakhono. Kwaye nanku omnye umba obalulekileyo. Isibakala sokuba ombane umbane yelanga ukuze kuncitshiswa kwiimeko kobhobhozo yabo. Ngako oko, amandla angehla inxalenye ebonakalayo ekhulwini. Kodwa ke oku akuthethi ukuba ungenza izibonelelo kunye ukusebenza isilawuli - oko moshchnostnymi ezinokubakho kufuneka kugubungela imida.

Ukongeza, umbuzo ukuba ukhethe njani umlawuli-solar uhlobo MPPT ibhetri, kufuneka ithathelwe ingqalelo neempawu radiation ekhutshwa. Kumphezulu womhlaba ubunzulu kwelanga, yongeza elinye-20% nomthamo kwezibonelelo yogcino. La ayikwazi ingqalelo umthetho, kodwa njengoko ingozi, kufuneka ukuba zinikwe ekubaleni ngamandla esisebenza.

Indlela yokwenza esisebenza yedwa?

isilawuli Model ngcono ngobuwena kubandakanya ukusetyenziswa iseti eqhelekileyo lweziqalelo. Phakathi kwazo kukho transistor into enokumelana ngoku ukuya kwi-49 A, eli relay isithuthi, eli resistor 120 ohms kunye elementi diode. Emva koko, lo relay liqhagamshelene accumulator, uze eyipasile ucingo resistor ukuya esangweni transistor. Ukusebenza, eli relay uphawu HIV kufuneka uvule isango, kwaye ngoku ukusuka umnqongo elangeni uya kucanda imilenze transistor kwi ibhetri.

Ukuba wenza umlawuli jikelele panel elanga kunye ngezandla zabo kunye ukulindela kubulawe ezizenzekelayo lombane ezingasetyenziswanga lwamandla, ukudityaniswa kwenkqubo diode inyanzelekile. Ebusuku, oko kuya kwenza ukuba indawo yolawulo elanga ilayithi, ukuphelisa ezongezelelweyo imodyuli ukusetyenziswa kwamandla.

Ngaba kunokwenzeka ukuba wenze ngaphandle umlawuli-solar?

Ngaphambi kokuba siphendule lo mbuzo, simele sikhumbule ukuba umsebenzi jikelele esisebenza njengenxalenye lomnqongo elanga. Ngayo, umnini ngokwawo ukulawula inkqubo ezibiza le pack battery ngenxa amandla okukhanya. Ukuba isilawuli akakho, ngoko ke amandla inkqubo yokuzaliswa kungathatha indawo ukuya kwinqanaba abilayo le electrolyte. Oko akukho ulawulo impefumlelwano lenjongo solar kwaye ibhetri ayikwazi ukuba akusebenzi. Enye into kukuba umlawuli ukuba ibhetri elangeni indawo ethile voltmeter. Xa uzingela amaxabiso kwincopho ombane kwaye umsebenzisi kuphela ukunqanda inkqubo zokuqhawula unit bebhetri. Le ndlela, Kakade, indisokolisa xa kuthelekiswa ulawulo ngokuzenzekelayo, kodwa kwimeko ukusetyenziswa ezinqabileyo inkqubo kwaye ukukugwebela ngokwayo.

isiphelo

Umenzi izilawuli elanga kunye namanye amacandelo ngenxa leeyunithi ezilolo hlobo, iinkampani ezininzi namhlanje. Esi sigaba asithathwa enomahluko ethile. Xa lentengiso components onjalo kuthengelwa 10-15 amawaka. Engange, kwaye yomgangatho elungileyo. Kakade ke, isilawuli ekhaya ukuba iseli elanga usebenzisa esezantsi-resistors kunye nezahlulo zombane Automotive iya kuxabisa sitshiphu, kodwa kusenokwenzeka ukuba babe nako ukwenza isiqinisekiso kwinqanaba elifunekayo kukuthembeka. A mzuzu uzinzo kunye nokhuseleko kubaluleke ngokukhethekileyo ukusebenzisa solar, ndingasathethi ibhetri. Ukuba yimpumelelo, izixhobo ze-solar isilawuli umnini umgangatho imodyuli iya kukwazi ukuthembela beqokelela oluzenzekelayo igunya ngaphandle kwimfuneko yokungenelela ngoncedo kwinkqubo sizukulwana.
