Kwinkqubo ye-erlid-rid-quated Grid, ixesha kunye nemozulu ziya kubangela utshintsho kwimitha yelanga, kwaye ivolthi kwindawo yamandla iya kuhlala itshintsha. Ukwenzela ukwandisa inani lombane ovelisiweyo, kuqinisekisiwe ukuba iiphaneli zelanga zinokuhanjiswa ngeyona ndlela iphezulu xa ilanga libuthathaka kwaye yomelele. Amandla, ihlala inkqubo yokuphucula i-boost yongezwa kwi-inverter yokwandisa i-voltage kwindawo yayo yokusebenza.
Olu shicilelo lulandelayo luchaza isizathu sokuba usebenzise ukomelela, kwaye ukonyusa indlela yokuphucula indlela enokukunceda ngayo inkqubo yamandla elanga ukwandisa amandla eSolar.
Kutheni ukonyusa isekethe?
Okokuqala, masijonge inkqubo ye-inverter eqhelekileyo kwintengiso. Inesekethe yokuphucula isekethe kunye nesekethe ye-inverter. Embindini iqhagamshelwe kwibhasi ye-DC.
Isekethe ye-inverter kufuneka kufuneka isebenze ngokufanelekileyo. Ibhasi ye-DC kufuneka iphakame kune-voltage ye-voltage (inkqubo yesigaba emithathu ingaphezulu kwexabiso le-voltage), ukuze amandla avelise kwigridi ngaphambili. Ngokwesiqhelo ukusebenzela impumelelo, i-DC ngebhasi ngokubanzi itshintsha ngokufumana i-voltage yegrid. , ukuqinisekisa ukuba iphezulu kunegridi yamandla.
Ukuba i-voltage yepaneli ingaphezulu kune-voltage efunekayo ye-Busbar, i-Inverter iya kusebenza ngokuthe ngqo, kwaye i-MPPP ye-MPPP iya kuqhubeka nokulandelela kwelona nqaku liphezulu. Nangona kunjalo, emva kokufikelela kubuncinci bemfuno ye-voltage, ayinakuncitshiswa kwakhona, kwaye eyona ndawo iphezulu yokusebenza ayinakufezekiswa. Ubungakanani be-MPPP iphantsi kakhulu, enciphisa kakhulu amandla okuvelisa amandla kunye nenzuzo yomsebenzisi ayinakuqinisekiswa. Ke kufuneka kubekho indlela yokwenza le mfutshane, kwaye iinjineli zisebenzisa isekethe yokuphucula ukuyenza le nto.
Ukomeleza njani ubungakanani be-MPTP ukukhulisa amandla?
Xa i-voltage yephaneli iphakamile kunevolthi efunwa yi-Busbar, isekethe yokuphucula i-booster ikwisimo sokuphumla, amandla ahanjiswa kwi-initter yayo, kwaye i-inverter igqibezela umkhondo we-MPPP. Emva kokufikelela kwi-voltage efunwayo yebhasi, i-iniverter ayinakuthatha ngaphezulu. I-MPTP yasebenza. Ngeli xesha, icandelo elinyusayo lithathe ulawulo lwe-MPTP, yalandelela i-MPPT, kwaye yaphakamisa ityholo lokuqinisekisa ukuba i-voltage.
Ngoluhlu olubanzi lwe-MPPPT yokulandela umkhondo, inkqubo ye-inverter inokudlala indima ebalulekileyo ekwandiseni i-voltage yeephaneli zelanga ngentsasa, inesiqingatha ebusuku, kunye neentsuku zemvula. Njengoko sinokubona kumzobo ongezantsi, amandla okwenyani icacile. Khuthaza.
Kutheni le nto i-inverter enkulu idla ngokusebenzisa izijikelezo ezininzi zokunyusa ukunyusa inani leesekethe ze-MPT?
Umzekelo, inkqubo ye-6KW, ngokwahlukeneyo i-3kw ukuya eluphahleni ezimbini, kuba zimbini ii-MPPT kufuneka zikhethwe ngeli xesha, kuba ilanga liziindawo ezimbini ezizimeleyo, ilanga liphezulu, kwaye i-B iphantsi kakhulu, emva kwemini. Xa kukho umahluko phakathi kweevolthi ezimbini, i-voltage ephantsi kufuneka inyuswe ukuze ihambise amandla ebhasini kwaye iqinisekise ukuba isebenza kwindawo ephezulu yamandla.
Isizathu esifanayo, umhlaba hully kwindlu entsonkothileyo, ilanga liya kufuna i-MPTP engaphezulu, ngoko ke ifuna i-MPTP engaphezulu, ngoko ke inamandla e-50kw-80k-8k-i-SPPP engaphandle kwe-3-4 ye-MPTP engazimeleyo.
