Yintoni ukuguqulwa kwempumelelo ye-photovoltaic inverter?Enyanisweni, izinga lokuguqulwa kwe-photovoltaic inverter libhekisela ekusebenzeni kakuhle kwe-inverter ukuguqula umbane okhutshwe yipaneli yelanga ibe ngumbane.Kwinkqubo yokuvelisa amandla e-photovoltaic, umsebenzi we-inverter kukuguqula umbane othe ngqo owenziwe yiphaneli yelanga kwi-alternating current, kwaye udlulise i-alternating current kwi-grid yamandla yenkampani yamandla, ukuguqulwa kokuguqulwa kwe-inverter kuphezulu, kwaye amandla okusetyenziswa ekhaya kunye nokuhanjiswa kuya kwanda.
Kukho izinto ezimbini ezimisela ukusebenza kwe-inverter:
Okokuqala, xa uguqula i-DC yangoku ibe yi-AC sine wave, isekethe esebenzisa i-semiconductor yamandla kufuneka isetyenziswe ukutshintsha i-DC yangoku.Ngeli xesha, i-semiconductor yamandla iya kutshisa kwaye ibangele ilahleko.Nangona kunjalo, ngokuphucula uyilo lwesekethe yokutshintsha, le lahleko inokuncitshiswa.kuncitshiswe kuncinci.
Okwesibini kukuphucula ukusebenza kakuhle ngenxainverterukulawula amava.Imveliso yangoku kunye ne-voltage yepaneli yelanga iya kutshintsha ngokukhanya kwelanga kunye nobushushu, kwaye i-inverter inokulawula ngokufanelekileyo ngoku kunye ne-voltage ukufezekisa ubuninzi bamandla, oko kukuthi, ukufumana amandla angcono kwixesha elifutshane.Okukhona indawo yamandla iphezulu, kokukhona iphezulu uguqulo olusebenzayo.Olu phawu lolawulo lwe-inverter luya kwahluka ukusuka kumenzi ukuya kumenzi, kwaye ukusebenza kwayo kokuguqulwa kuya kwahluka.Ngokomzekelo, ezinye ii-inverters zinezinga eliphezulu lokuguqulwa kwamandla aphezulu, kodwa ukuguqulwa okuphantsi kokusebenza kakuhle kwimveliso yamandla aphantsi;abanye bagcina i-avareji yoguqulo olusebenzayo ukusuka kwimveliso yamandla aphantsi ukuya kwimveliso yamandla aphezulu.Ngoko ke, xa ukhetha i-inverter, kuyimfuneko ukuqwalasela ukuhambelana kunye neempawu eziphumayo zepaneli yelanga efakiweyo.
