Inverter wani nau'i ne na na'urar daidaita wutar lantarki wanda ya ƙunshi na'urorin semiconductor, galibi ana amfani da su don juyar da ikon DC zuwa ikon AC, gabaɗaya ya ƙunshi da'ira mai haɓakawa da da'irar inverter gada.Da'irar haɓaka tana haɓaka ƙarfin wutar lantarki na DC na tantanin halitta zuwa ƙarfin wutar lantarki na DC da ake buƙata ta sarrafa fitarwar inverter;Da'irar gadar inverter tana canza ƙarfin wutar lantarki na DC zuwa mitar AC ta gama gari daidai.
Inverter, wanda kuma aka sani da mai sarrafa wutar lantarki, ana iya raba shi zuwa nau'ikan samar da wutar lantarki masu zaman kansu da haɗin grid bisa ga amfani da inverter a cikin tsarin samar da wutar lantarki na hotovoltaic.Dangane da yanayin juzu'i na waveform, ana iya raba shi zuwa mai jujjuyawar kalaman murabba'i, mai jujjuyawar matakin mataki, inverter sine da kuma haɗa inverter mai mataki uku.Don inverter da aka yi amfani da shi a cikin tsarin haɗin grid, bisa ga kasancewar ko rashin na'urar wuta za a iya raba shi zuwa nau'in mai juyawa da nau'in mai canzawa.Babban sigogi na fasaha na hasken rana photovoltaic inverter sune:
1. Rated fitarwa ƙarfin lantarki
Inverter pv yakamata ya iya fitar da ƙimar ƙarfin lantarki a cikin kewayon juzu'i da aka yarda na ƙayyadaddun wutar lantarki dc da aka ƙayyade.Gabaɗaya, lokacin da aka ƙididdige ƙarfin fitarwar ya zama 220v mai ƙarfi-ɗaya da 380v mai hawa uku, juzu'in canjin wutar lantarki yana da tanadi masu zuwa.
(1) A cikin tsayayyen aiki na jiha, ana buƙatar juzu'in canjin wutar lantarki kada ya wuce ± 5% na ƙimar ƙima.
(2) Rashin wutar lantarki ba zai wuce ± 10% na ƙimar da aka ƙima ba idan akwai maye gurbi.
(3) A ƙarƙashin yanayin aiki na yau da kullun, ƙimar rashin daidaituwa na fitowar wutar lantarki mai ƙarfi uku na inverter kada ta wuce 8%.
(4) Karɓar igiyar wutar lantarki mai matakai uku (Sine Wave) bai kamata ya wuce 5% ba, kuma fitowar lokaci ɗaya kada ta wuce 10%.
(5) Mitar wutar lantarki ta inverter AC a ƙarƙashin yanayin aiki na yau da kullun yakamata ya kasance cikin 1%.Mitar wutar lantarki da aka ƙayyade a cikin ma'auni na ƙasa gb/t 19064-2003 ya kamata ya kasance tsakanin 49 da 51hz.
2, ɗora nauyi
Matsakaicin ƙarfin ɗaukar nauyi yana nuna ƙarfin inverter tare da nauyin inductive ko kaya mai ƙarfi.Ƙarƙashin yanayi na sine, ma'aunin wutar lantarki ya tashi daga 0.7 zuwa 0.9, kuma ƙimar shine 0.9.A cikin yanayin wani nau'i mai nauyin nauyi, idan ma'aunin wutar lantarki na inverter ya ragu, ƙarfin inverter da ake buƙata zai karu, wanda zai haifar da karuwa a farashi, a lokaci guda, ikon da aka bayyana na tsarin photovoltaic AC madauki yana ƙaruwa, madauki halin yanzu yana ƙaruwa, asarar babu makawa za ta karu, kuma ingancin tsarin zai ragu.
3. Rated fitarwa halin yanzu da kuma iya aiki
Ƙididdigar fitarwa na halin yanzu yana nufin ƙimar fitarwa na halin yanzu na inverter a cikin ƙayyadadden kewayon ma'aunin ƙarfin kaya (raka'a: A).Ƙarfin fitarwa da aka ƙididdige shi ne samfurin ƙarfin fitarwa da aka ƙididdigewa da ƙimar fitarwa na halin yanzu na inverter lokacin da ƙarfin fitarwa ya kasance 1 (watau babban nauyin juriya mai tsafta), a cikin KVA ko kW.
