1. Kusho ukuthini izinga lokushisa?

Ukuhlekisa ukuncishiswa okulawulwayo kwamandla we-inverter. Ekusebenzeni okujwayelekile, ama-inverterter asebenza endaweni yawo ephezulu yamandla. Kuleli phuzu lokusebenza, isilinganiso phakathi kwe-PV Voltage kanye nemiphumela yamanje ye-PV kumandla aphezulu. Iphoyinti lamandla aphezulu lishintsha njalo ngokuya ngamazinga we-solarrradiation namazinga we-PV module lokushisa.

Ukushisa okushisa kuvimbela abakwa-semiconductor obucayi ku-inverter kusuka ekushiseni ngokweqile. Lapho izinga lokushisa elivumelekile kwizakhi ezibhekisiwe lifinyelelwa, i-inverter ishintsha iphuzu layo elisebenzayo liye ezingeni elincishisiwe lamandla. Amandla ancishiswa ngezinyathelo. Kwezinye izimo ezedlulele, i-inverter izovala ngokuphelele. Lapho nje izinga lokushisa lezakhi ezibucayi liwela ngaphansi kwenani elibucayi futhi, i-inverter izobuyela endaweni efanelekile yokusebenza.

Yonke imikhiqizo yeRenac isebenza ngamandla aphelele futhi i-currents egcwele kuze kube yilapho kushisa okuthile, ngaphezulu okungase kusebenze ngezilinganiso ezincishisiwe ukuvikela ukulimala kwensiza. Le ncwadi yezobuchwepheshe ifingqa izakhiwo ze-de-rating ze-renac inverterers nokuthi yini ebangela izinga lokushisa okululazayo nokuthi yini engenziwa ukuyivimba.

Incwajana

Onke amazinga okushisa alo mbhalo abhekisela ekushiseni okukhona.

2. Izakhiwo ze-de-rating ze-renac inverterers

Ama-inverters esigaba esisodwa

Amamodeli alandelayo we-Inverter asebenza ngamandla aphelele futhi agcwele ama-currents aze afike emazingeni okushisa abhalwe etafuleni elingezansi, futhi asebenze ngezilinganiso ezincishisiwe ezifika ku-113 ° F / 45 ° C ngokusho kwamagrafu aphansi. Amagrafu achaza ukuncishiswa kwamanje maqondana nokushisa. Ukukhishwa kwangempela akusoze kwaqhamuka kunesilinganiso esiphakeme esichaziwe kuma-datasheets we-inverter, futhi kungahle kube ngaphansi kunalokho okuchazwe ku-graph ngezansi kwe-inverter model ngezwe ngalinye negridi.

Ama-inverters amathathu esigaba

Amamodeli alandelayo we-Inverter asebenza ngamandla aphelele futhi agcwele ama-currents aze afike emazingeni okushisa abhalwe etafuleni elingezansi, futhi asebenze ngezilinganiso ezincishisiwe ezifika ku-113 ° F / 45 ° C, 90 ° C / 50 ° C, 50 ° C ngokusho kwamagrafu aphansi. Amagrafu achaza ukuncishiswa kwamanje (amandla) maqondana nokushisa. Ukukhishwa kwangempela akusoze kwaqhamuka kunesilinganiso esiphakeme esichaziwe kuma-datasheets we-inverter, futhi kungahle kube ngaphansi kunalokho okuchazwe ku-graph ngezansi kwe-inverter model ngezwe ngalinye negridi.

Ama-Hybrid Averterers

Amamodeli alandelayo we-Inverter asebenza ngamandla aphelele futhi agcwele ama-currents aze afike emazingeni okushisa abhalwe etafuleni elingezansi, futhi asebenze ngezilinganiso ezincishisiwe ezifika ku-113 ° F / 45 ° C ngokusho kwamagrafu aphansi. Amagrafu achaza ukuncishiswa kwamanje maqondana nokushisa. Ukukhishwa kwangempela akusoze kwaqhamuka kunesilinganiso esiphakeme esichaziwe kuma-datasheets we-inverter, futhi kungahle kube ngaphansi kunalokho okuchazwe ku-graph ngezansi kwe-inverter model ngezwe ngalinye negridi.

3. Isizathu sokushisa okushisa

Ukushisa okushisa kwenzeka ngenxa yezizathu ezahlukahlukene, kufaka phakathi okulandelayo:

• I-inverter ayikwazi ukuqeda ukushisa ngenxa yezimo ezingezinhle zokufaka.
• I-inverter isebenza elangeni eliqondile noma emazingeni okushisa akhona avelele avimbela ukushiyeka okuvuthayo okwanele.
• I-inverter ifakwe kwikhabethe, isembatho noma enye indawo encane ebiyelwe. Isikhala esilinganiselwe asisilungele ukupholisa kwe-Inverter.
• I-PV ARRAY ne-Inverter kufakwe ama-mismall (amandla we-PV array kuqhathaniswa namandla we-inverter).
• Uma indawo yokufaka ye-inverter isendaweni evuthayo (isib. Ukuphakama kwezindlela eziphezulu zokuphakama okusebenzayo noma ngenhla okusho izinga lolwandle, bheka isigaba "idatha yokusebenza kwe-inverter). Ngenxa yalokhu, izinga lokushisa lihlekisa kakhulu lingenzeka njengoba umoya ungami okungenani emincane ezindaweni eziphakeme futhi ngenxa yalokho uyakwazi ukupholisa izakhi.

4. Ukuvimbela ukushisa kwama-inverters

Ama-inverter avuselela anezinhlelo zokupholisa ezihambisana namandla nokuklanywa kwazo. Ama-Inverterers apholile aqeda ukushisa emkhathini ngokusebenzisa izinsimbi zokushisa kanye fan.

Lapho nje idivaysi ikhiqiza ukushisa okwengeziwe kunokuvalelwa kwayo, ukushintshwa kwangaphakathi kwangaphakathi (ukushintshwa kwabalandeli lapho ukushisa okushisa kufinyelela ku-70 ℃) futhi kudonsele emoyeni ngemithi ebiyelwe. Umlandeli ulawulwa ngokusheshisa: Iphenduka ngokushesha njengoba izinga lokushisa likhuphuka. Inzuzo yokupholisa ukuthi i-inverter ingaqhubeka ukondla ngamandla aso aphezulu njengoba izinga lokushisa likhuphuka. I-inverter ayihlehliswa kuze kube yilapho uhlelo lokupholisa lufinyelela emikhawulweni yomthamo wayo.

Ungakugwema ukufuthelwa kwezinga lokushisa ngokufaka ama-inverters ngendlela yokuthi ukushisa kuhlakazeke kahle:

• Faka ama-inverterers ezindaweni ezipholile(isib

• Musa ukufaka i-inverter kwikhabhinethi, indawo yokuvalwa noma enye indawo encane ebiyelwe, kufanele kudluliselwe ukusakazwa komoya ukuze kuqedwe ukushisa okukhiqizwe yiyunithi elenziwe yiyunithi.
• Musa ukudalula i-inverter ukuqondisa i-solar irradiation. Uma ufaka i-inverter ngaphandle, uyibeka emthunzini noma ufake uphahla ophahleni.

• Gcina ukukhishwa okuncane okuvela kuma-inverters aseduze noma ezinye izinto, njengoba kuchaziwe kwincwajana yokufaka. Khulisa imvume uma kungenzeka amazinga okushisa aphezulu endaweni yokufaka.

• Lapho ufaka ama-inverterers amaningana, gcina imvume eyanele ezungeze ama-inverters ukuze uqinisekise indawo eyanele yokufakelwa kokushisa.

5. Isiphetho

Ama-Inverter ane-Renac anezinhlelo zokupholisa ezenzelwe amandla abo nokwakhiwa kwazo, izinga lokushisa elingenayo alinayo imiphumela emibi kwi-inverter, kepha ungagwema ukufukula ngokufaka inverters ngendlela efanele.
