Yini eyenziwa yi-solar inverter?

I-inverter yelangaiyingxenye ebalulekile yesistimu yokukhiqizwa kwamandla elanga. Idlala indima ebalulekile ekuguquleni ugesi wamandla aqondile (DC) okhiqizwa ngamaphaneli elanga abe ugesi wamandla ashintshanayo (AC) ongasetshenziswa ukunika amandla amakhaya namabhizinisi. Empeleni, i-solar inverter isebenza njengebhuloho phakathi kwamaphaneli elanga nezinto zikagesi, iqinisekisa ukuthi amandla akhiqizwa ngamaphaneli elanga ayahambisana negridi ekhona.

Ngakho-ke, yini eyenziwa yi-solar inverter? Ake sibheke imininingwane.

Okokuqala, i-solar inverter inesibopho sokuguqula amandla e-DC abe amandla e-AC.Amaphaneli elangaikhiqiza ugesi oqondile uma ivezwa elangeni. Kodwa-ke, izinto eziningi zasekhaya kanye negridi kagesi zisebenzisa ugesi oshintshashintshayo. Yilapho ama-solar inverters asebenza khona. Iguqula ugesi we-DC okhiqizwa amaphaneli elanga ube ugesi we-AC, okwenza ufanelekele ukunika amandla amadivayisi asekhaya futhi inikeze amandla amaningi emuva kugridi.

Ngaphezu kwalokho, ama-solar inverters adlala indima ebalulekile ekwenzeni ngcono ukusebenza kweizinhlelo zamandla elanga. Bahlonyiswe ngobuchwepheshe be-Maximum Power Point Tracking (MPPT), obubavumela ukuthi balawule njalo i-voltage kanye nogesi ukuqinisekisa ukuthi amaphaneli elanga asebenza kahle kakhulu. Lokhu kusho ukuthi i-solar inverter ingakhipha inani elikhulu lamandla kumaphaneli elanga ngaphansi kwezimo ezahlukene zokukhanya kwelanga, ekugcineni ikhulise ukukhishwa kwamandla kohlelo.

Ngaphezu kokuguqula nokwenza ngcono ugesi okhiqizwa amaphaneli elanga, ama-solar inverter nawo ahlinzeka ngezici ezibalulekile zokuphepha. Aklanyelwe ukuqapha ukuphuma kwamandla kwamaphaneli elanga nokuvala uma kwenzeka kuphazamiseka igridi. Lokhu kubalulekile ekuphepheni kwabasebenzi bokulungisa nokuvimbela noma yimuphi umonakalo ongaba khona ohlelweni lwelanga ngesikhathi kuphazamiseka.

Kunezinhlobo ezahlukene zama-solar inverters emakethe, ngayinye inezici zayo ezihlukile kanye namakhono ayo. Izinhlobo ezivame kakhulu zifaka phakathi ama-string inverters, ama-microinverters kanye nama-power optimizer. Ama-string inverters avame ukusetshenziswa ezinhlelweni zamandla elanga zendabuko lapho amaphaneli amaningi elanga exhunywe khona ngokulandelana. Ama-microinverters, ngakolunye uhlangothi, afakwa kuphaneli ngayinye yelanga, okuvumela ukuguquguquka okukhulu kanye nokuqapha ukusebenza. Ama-Power optimizer awubuchwepheshe obusha obunikeza izinzuzo ezifanayo nama-microinverters ngokwenza ngcono ukusebenza kwephaneli ngayinye yelanga.

Eminyakeni yamuva nje, intuthuko kwezobuchwepheshe be-solar inverter iholele ekuthuthukisweni kweama-inverter ahlanganisiwe, okungahlanganiswa futhi neizinhlelo zokugcina amandlanjengamabhethri. Lokhu kuvumela abanikazi bezindlu ukuthi bagcine amandla elanga amaningi ukuze bawasebenzise ngezikhathi zokukhanya kwelanga okunganele noma ukucima kukagesi, okuthuthukisa ukuthembeka nokuqina kwezinhlelo zikagesi welanga.

Ngamafuphi, i-solar inverter iyisici esibalulekile sohlelo lokukhiqizwa kwamandla elanga. Inesibopho sokuguqula amandla e-DC akhishwa amaphaneli elanga abe amandla e-AC, ithuthukise ukusebenza kohlelo futhi iqinisekise ukuphepha nokuthembeka. Njengoba isidingo samandla avuselelekayo siqhubeka nokukhula, ama-solar inverter azodlala indima ebaluleke kakhulu ekukhuthazeni ukwamukelwa kabanzi kwamandla elanga njengomthombo wamandla ohlanzekile noqhubekayo.
