I-inverter yingqondo nentliziyo yenkqubo yokuvelisa amandla e-photovoltaic. Kwinkqubo yokuvelisa amandla e-photovoltaic yelanga, amandla aveliswa yi-photovoltaic array yi-DC power. Nangona kunjalo, imithwalo emininzi ifuna amandla e-AC, kwaye inkqubo yokubonelela ngombane ye-DC inemida emikhulu kwaye ayilungele ukuguqula i-voltage. , uluhlu lokusetyenziswa komthwalo nalo lulinganiselwe, ngaphandle kwemithwalo yamandla ekhethekileyo, ii-inverters ziyafuneka ukuguqula amandla e-DC abe ngamandla e-AC. I-photovoltaic inverter yintliziyo yenkqubo yokuvelisa amandla e-photovoltaic yelanga, eguqula umbane othe ngqo oveliswa ziimodyuli ze-photovoltaic ube ngumbane otshintshanayo, kwaye iwudlulisele kumthwalo wengingqi okanye kwigridi, kwaye sisixhobo se-elektroniki samandla esinemisebenzi yokukhusela enxulumene nayo.
I-solar inverter yenziwe ikakhulu ziimodyuli zamandla, iibhodi zesekethe zolawulo, ii-circuit breakers, izihluzi, ii-reactors, ii-transformers, ii-contactors kunye neekhabhathi. Inkqubo yemveliso ibandakanya ukucubungula kwangaphambili kwezixhobo ze-elektroniki, ukuhlanganiswa komatshini opheleleyo, ukuvavanywa kunye nokupakishwa komatshini opheleleyo. Uphuhliso lwayo luxhomekeke kuphuhliso lwetekhnoloji ye-elektroniki yamandla, itekhnoloji yesixhobo se-semiconductor kunye netekhnoloji yokulawula yanamhlanje.
Kwii-solar inverters, ukuphucula ukusebenza kakuhle koguqulo lombane yinto ehlala ihleli, kodwa xa ukusebenza kakuhle kwenkqubo kusanda, phantse kube yi-100%, ukuphuculwa kokusebenza ngakumbi kuya kuhamba nokusebenza ngexabiso eliphantsi. Ke ngoko, indlela yokugcina ukusebenza kakuhle, kodwa nokugcina ukhuphiswano oluhle lwamaxabiso kuya kuba sisihloko esibalulekileyo okwangoku.
Xa kuthelekiswa nemizamo yokuphucula ukusebenza kakuhle kwe-inverter, indlela yokuphucula ukusebenza kakuhle kwenkqubo ye-inverter yonke kancinci kancinci iba ngomnye umba obalulekileyo kwiinkqubo zamandla elanga. Kwi-solar array, xa kuvela indawo yesithunzi yengingqi ye-2%-3%, kwi-inverter esebenzisa umsebenzi we-MPPT, amandla okukhupha enkqubo ngeli xesha anokwehla malunga ne-20% xa amandla okukhupha engekho semgangathweni. Ukuze uzivumelanise ngcono nemeko efana nale, yindlela esebenzayo kakhulu yokusebenzisa i-MPPT enye ukuya kwenye okanye imisebenzi emininzi yokulawula i-MPPT kwiimodyuli zelanga enye okanye engaphelelanga.
Ekubeni inkqubo ye-inverter ikwimeko yokusebenza eqhagamshelwe kwigridi, ukuvuza kwenkqubo emhlabeni kuya kubangela iingxaki ezinkulu zokhuseleko; ukongeza, ukuze kuphuculwe ukusebenza kakuhle kwenkqubo, uninzi lwee-solar arrays ziya kuqhagamshelwa kuthotho ukwenza i-voltage ephezulu ye-DC output; Ngenxa yokubakho kweemeko ezingaqhelekanga phakathi kwee-electrodes, kulula ukuvelisa i-DC arc. Ngenxa ye-voltage ephezulu ye-DC, kunzima kakhulu ukuyicima i-arc, kwaye kulula kakhulu ukubangela umlilo. Ngokwamkelwa ngokubanzi kweenkqubo ze-solar inverter, umba wokhuseleko lwenkqubo uya kuba yinxalenye ebalulekileyo yetekhnoloji ye-inverter.
