Isiguquli selanga sidlala indima ebalulekile ohlelweni lwe-photovoltaic (PV) ngokuguqula ugesi wamanje (DC) okhiqizwe amaphaneli elanga ube ugesi wamanje (AC) oshintshanayo ongasetshenziswa izinto zasendlini noma ofakwe kugridi kagesi.
Isingeniso Solar Inverters
Ama-Solar inverters ayizingxenye ezibalulekile zezinhlelo zamandla elanga, anesibopho sokuguqula amandla e-DC akhiqizwa amaphaneli elanga abe amandla e-AC afanele ukusetshenziswa ezindlini nasemabhizinisini. Lolu shintsho lubalulekile ngoba izinto eziningi zikagesi kanye negridi kagesi kusebenza ngamandla e-AC. Ama-inverters aqinisekisa ukuthi ugesi okhiqizwa ama-solar panel uyahambisana nalezi zinhlelo.
Izinhlobo zama-Solar Inverters
Ama-Inverters Ahlanganiswe Igridi:
Ukusebenza: Lezi ziguquli zivumelanisa ugesi we-AC eziwukhiqizayo nogesi wegridi yensiza ye-AC. Ziwuhlobo oluvame kakhulu lwama-solar inverters asetshenziswa ezindaweni zokuhlala nezokuhweba.
Izinzuzo: Ama-inverter aboshwe ngegridi avumela ukulinganisa kwenetha, lapho ugesi oweqile okhiqizwa ama-solar panel ungabuyiselwa kugridi, ngokuvamile okuholela ekukhokheni noma ekuncishisweni kwezikweletu zikagesi.
Iziguquli ze-Off-Grid:
Ukusebenza: Idizayinelwe amasistimu azimele angaxhumekile kugridi yokusetshenziswa. Ngokuvamile zifaka isitoreji sebhethri ukuze sigcine ugesi omningi okhiqizwa emini ukuze usetshenziswe ebusuku noma ngezikhathi zokukhanya kwelanga okuphansi.
Izinzuzo: Nikeza ukuzimela kwamandla ezindaweni ezikude noma ezindaweni ezinokufinyelela kwegridi okungathembekile. Zivame ukusetshenziswa ezindlini ezingaphandle kwegridi, amakhabethe, nasemibhoshongweni yokuxhumana ekude.
Iziguquli zeHybrid (Isipele Sebhethri):
Ukusebenza: Lawa ma-inverters ahlanganisa izici zama-inverter ahlanganiswe negridi nangaphandle kwegridi. Angasebenza kokubili ngokuxhumeka kwegridi nangaphandle, ahlanganise isitoreji sebhethri ukuze akhulise ukuzisebenzisela amandla elanga.
Izinzuzo: Nikeza ukuguquguquka nokuqina ngokunikeza amandla ayisipele phakathi nokucisha kwegridi kuyilapho uvumela nokugcinwa kwamandla ukuze kusetshenziswe ngokugcwele amandla elanga.
Ukusebenza kanye Nezingxenye
Ukuguqulwa kwe-DC kuya ku-AC: Iziguquli zelanga ziguqula ugesi we-DC okhiqizwe amaphaneli elanga uwenze ugesi we-AC ngenqubo ehlanganisa amadivaysi okushintsha ama-semiconductor afana ne-insulated gate bipolar transistors (IGBTs).
I-Maximum Power Point Tracking (MPPT): Ama-inverter amaningi ahlanganisa ubuchwepheshe be-MPPT, obuthuthukisa ukuphuma kwephaneli yelanga ngokuqhubeka nokulungisa i-voltage yokusebenza kanye neyamanje ukuze kuqinisekiswe ukukhishwa kwamandla aphezulu ngaphansi kwezimo ezihlukahlukene zokukhanya kwelanga.
Ukuqapha Nokulawula: Iziguquli zesimanje zivame ukuza namasistimu okuqapha ahlinzeka ngedatha yesikhathi sangempela ekukhiqizweni kwamandla, isimo sesistimu, namamethrikhi okusebenza. Lawa masistimu avumela abasebenzisi ukuthi balandelele ukukhiqizwa kwamandla, bahlonze izinkinga ezingaba khona, futhi bathuthukise ukusebenza kahle kwesistimu.
Ukusebenza kahle kanye Nokwethenjelwa
Ukusebenza kahle: Ama-Solar inverters asebenza ngamazinga aphezulu okusebenza kahle, ngokuvamile asukela ku-95% kuya ku-98%. Lokhu kusebenza kahle kuqinisekisa ukulahleka kwamandla okuncane phakathi nenqubo yokuguqulwa kwe-DC kuya ku-AC, okwandisa isivuno samandla esiphelele sohlelo lwe-solar PV.
Ukuthembeka: Ama-Inverters aklanyelwe ukumelana nezimo ezihlukahlukene zemvelo ezifana nokushintshashintsha kwezinga lokushisa, umswakama, nokuchayeka elangeni. Ziphinde zihlonyiswe ngezici zokuvikela ezifana nokuvikela ukukhuphuka, ukutholwa kwephutha eliphansi, nokuvikela okudlulele ukuze kuthuthukiswe ukuqina nokuphepha kwesistimu.
Isiphetho
Kafushane, inverter yelanga iyingxenye ebalulekile yezinhlelo zamandla elanga, enesibopho sokuguqula ugesi we-DC okhiqizwe amaphaneli elanga abe ugesi we-AC ofanele ukusetshenziswa ezindlini, amabhizinisi, kanye negridi kagesi. Ngezinhlobo ezahlukene ezitholakalayo—ama-grid-tieed, off-grid, nama-hybrid inverters—ngasinye sisebenzisa izinjongo ezithile kusukela ekukhuliseni ukuzisebenzisela amandla kuya ekunikezeni amandla ayisipele. Njengoba ubuchwepheshe belanga buthuthuka, ama-inverters ayaqhubeka nokuguquguquka, esebenza kahle kakhulu, ethembekile, futhi ehlanganiswe namakhono athuthukile okuqapha nokulawula ukuze kusetshenziswe amandla elanga.
