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 yipaneli 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.
