1. Ukuguqulwa kokulahlekelwa okuphansi
Esinye sezici ezibaluleke kakhulu ze-inverter ukusebenza kahle kwayo kokuguqulwa, inani elimelela ingxenye yamandla afakwe lapho i-Direct current ibuyiswa njengamanje okushintshanayo, futhi amadivaysi esimanje asebenza cishe ngama-98%.
2. Ukwenza kahle kwamandla
Ijika lesici samandla semojula ye-PV incike kakhulu ekukhanyeni okukhazimulayo kanye nezinga lokushisa lemodyuli, ngamanye amazwi, kumanani ashintsha usuku lonke, ngakho-ke, i-inverter kufanele ithole futhi iqhubeke ibheka amandla aphezulu. ijika lesici.indawo yokusebenza ukuze kukhishwe amandla aphezulu kumojula ye-PV esimweni ngasinye.
3. Ukuqapha kanye Nokuvikela
Ngakolunye uhlangothi, i-inverter iqapha ukukhiqizwa kwamandla we-photovoltaic power plant, futhi ngakolunye uhlangothi, iphinde iqaphe igridi exhunywe kuyo.Ngakho-ke, uma kunenkinga ngegridi, kufanele inqamule ngokushesha isitshalo kugridi ngezizathu zokuphepha, kuye ngezidingo zomqhubi wendawo.
Ngaphezu kwalokho, ezimweni eziningi, i-inverter ifakwe idivayisi engaphazamisa ngokuphepha ukugeleza kwamanje kumamojula we-PV.Njengoba imojuli ye-PV ihlala isebenza uma ikhipha ukukhanya, ayikwazi ukuvalwa.Uma izintambo ze-inverter zinqanyulwa ngesikhathi sokusebenza, ama-arcs ayingozi angase akheke futhi lawa ma-arcs ngeke acinywe yi-current eqondile.Uma i-breaker circuit ihlanganiswe ngokuqondile ku-converter ye-frequency, ukufakwa kanye nomsebenzi we-wiring kungancishiswa kakhulu.
4. Ukuxhumana
Isixhumi esibonakalayo sokuxhumana kusiguquli sefrikhwensi sivumela ukulawula nokuqapha kwawo wonke amapharamitha, idatha yokusebenza nokuphumayo.Ngoxhumano lwenethiwekhi, i-fieldbus yezimboni efana ne-RS 485, kungenzeka ukubuyisa idatha bese usetha imingcele ye-inverter.Ezimweni eziningi, idatha ibuyiswa nge-data logger eqoqa idatha kusuka kuma-inverter amaningi futhi, uma kudingeka, iwathumele kuphothali yedatha ye-inthanethi yamahhala.
5. Ukulawula izinga lokushisa
Ukushisa esimweni se-inverter nakho kuthinta ukusebenza kahle kokuguqulwa, uma ukuphakama kukhulu kakhulu, i-inverter kufanele inciphise amandla, futhi kwezinye izimo amandla emojula atholakalayo awakwazi ukusetshenziswa ngokugcwele.Ngakolunye uhlangothi, indawo yokufaka ithinta izinga lokushisa - indawo epholile eqhubekayo ilungile.Ngakolunye uhlangothi, kuncike ngokuqondile ekusebenzeni kwe-inverter: ngisho nokusebenza kahle kwe-98% kusho ukulahlekelwa kwamandla angu-2%.Uma amandla esitshalo angu-10 kW, amandla okushisa aphezulu asengama-200 W.
6. Ukuvikelwa
Izindlu ezingamelana nesimo sezulu, ezinesigaba sokuvikela i-IP 65, zivumela inverter ukuthi ifakwe ngaphandle kunoma iyiphi indawo efiswayo.Izinzuzo: Lapho usondelana kakhulu namamojula angafakwa ku-inverter, uzochitha kancane ekuxhumeni izintambo ze-DC ezibiza kakhulu.
