Ngenxa yokwehlukahluka kwezakhiwo, kuzoholela nakanjani ekuhlukanisweni kokufakwa kwephaneli yelanga. Ukuze wandise ukusebenza kahle kwamandla elanga ngenkathi kucatshangelwa ukubukeka okuhle kwesakhiwo, lokhu kudinga ukuhlukaniswa kwama-inverters ethu ukufeza indlela engcono kakhulu yamandla elanga. Ukuguqulwa. Izindlela ezivame kakhulu ze-inderter ze-solar emhlabeni yilezi: ama-inverters aphakathi nendawo, ama-inverters entambo, ama-inver-string ama-inverters kanye ne-inverner yezakhi. Manje sizohlaziya ukusetshenziswa kwama-inverters amaningana.
Ama-inverters aphakathi asetshenziswa ngokuvamile ezinhlelweni ezineziteshi ezinkulu zamandla we-Photovoltaic ("10kW). Izintambo eziningi ze-Photovoltaic ezihambisanayo zixhunywe kokufakwa kwe-DC kwe-inverter ephakathi nendawo. Ngokuvamile, amamojula wamandla we-IGBT amathathu asetshenziselwa amandla aphezulu. Amandla aphansi asebenzisa ama-transistors asebenza ngomkhakha kanye nesilawuli sokuguqulwa kwe-DSP ukuthuthukisa ikhwalithi yamandla kagesi akhiqizwayo, okwenza kusondele kakhulu ku-Sine Wave yamanje. Isici esikhulu kunazo zonke amandla aphezulu nezindleko eziphansi zohlelo. Kodwa-ke, kuyathinteka ekufanisweni kwezintambo ze-Photovoltaic kanye nokwenziwa okuyingxenye, okuholela ekusebenzeni nasekusebenzeni kwamandla wohlelo lonke lwe-Photovoltaic. Ngasikhathi sinye, ukuthembeka kwesizukulwane samandla sohlelo lonke lwe-Photovoltaic kuthintwa yisimo sokusebenza esingesihle seqembu lePhotovoltaic Unit. Ukuqondisa kwakamuva kokucwaninga kuwukusetshenziswa kwe-Space Vector monation control kanye nokuthuthukiswa kokuxhunyaniswa okusha kwe-Inverter Topology ukuthola ukusebenza okuphezulu ngaphansi kwezimo zomthwalo ezingxenye.
Ku-inverter ephakathi nendawo yeSolarmax, ungakwazi ukunamathisela ibhokisi le-Photovoltaic Array Array lokuqapha intambo ngayinye ye-potovoltaic Windsurfing string. Uma enye yezintambo ingasebenzi kahle, uhlelo luzodlulisela lolu lwazi kulawulo olukude ngasikhathi sinye, le ntambo ingamiswa ngokulawula okukude, ukuze ukwehluleka kwentambo yezintambo ze-photovoltaic ngeke kunciphise futhi kuthinte umsebenzi wohlelo lonke lwe-Photovoltaic.
I-string inverters isibe ama-inverters athandwa kakhulu emakethe yamazwe omhlaba. I-inverter yentambo isuselwa kumqondo ojwayelekile. I-Photovoltaic String ngayinye (i-1kw-5kw) idlula kwi-inverter, inomkhondo ophezulu wamandla we-Power Peak ekugcineni kwe-DC, futhi ixhunyiwe ngokufana ekugcineni kwe-AC. Izitshalo eziningi eziningi zamandla ze-Photovoltaic zisebenzisa ama-inverters wentambo. Inzuzo ukuthi ayithintwa ngumehluko module kanye nemithunzi phakathi kwezintambo, futhi ngasikhathi sinye yehlisa iphuzu elisebenzayo lokusebenza kwamamojula we-Photovoltaic
Ukungaziphathi kahle, ngaleyo ndlela kwandise inani lesizukulwane samandla. Lezi zinzuzo zobuchwepheshe azigcini nje ngokunciphisa izindleko zohlelo, kodwa futhi zandisa ukwethenjwa kohlelo. Ngasikhathi sinye, kwalethwa "umqondo we-" master-inceku "phakathi kwezintambo, ukuze kuthi lapho umucu owodwa wamandla kagesi ungakwazi ukwenza umsebenzi owodwa we-inverter ohlelweni, amasethi amaningana emicu ye-photovoltaic axhunyiwe ndawonye, futhi eyodwa noma eziningi zazo zingasebenza. , Ukuze kukhiqize ugesi owengeziwe. Umqondo wakamuva ukuthi ama-inverter ambalwa akha "iqembu" ukuze athathe isikhundla somqondo "we-master-inceku", okwenza ukuthembeka kohlelo lube isinyathelo futhi. Njengamanje, ama-inverters aguqulayo aguqukayo athathe ukuhola.
I-inverter ye-Multi-string ithatha izinzuzo ze-inverter ephakathi nendawo kanye ne-string inverter, igwema ukushiyeka kwayo, futhi ingafakwa eziteshini zamandla ze-Photovoltaic zama-Kilowatts amaningana. E-Inverter ye-Multi-string, ukulandelela okuphezulu kwamandla okulandela amandla kanye nabaguquli be-DC-To-DC kufakiwe. Lawa ama-DCs aguqulwa abe amandla e-AC nge-inverter ejwayelekile ye-DC-To-Ac-AC futhi exhunywe kugridi. Amanani ahlukaniswe alinganiselwe ezintambo ze-Photovoltaic (ezinjengokuthi: Amandla ahlukene alinganiselwe, inani elihlukile lezakhi kuyunithi ngayinye, futhi izintambo ze-angles ezihlukile, futhi zixhumene ne-inverter evamile, futhi i-string ngayinye isebenza emandleni abo aphezulu Peak.
Ngasikhathi sinye, ubude bekhebula le-DC buncishisiwe, umphumela wesithunzi phakathi kwezintambo nokulahleka okubangelwa umehluko phakathi kwezintambo kuncishisiwe.
I-Unverter ye-Compenent ukuxhuma ingxenye ngayinye ye-Photovoltaic kwi-inverter, futhi ingxenye ngayinye inokulandela okuphezulu kwamandla okuphezulu, ukuze isakhi kanye ne-inverter kuhambelana kangcono. Imvamisa esetshenziswa ku-50W kuya ku-400W izitshalo zamandla kagesi, ukusebenza kahle okuphelele kuphansi kune-inverters yentambo. Njengoba ixhumeke ngokufana nge-AC, lokhu kwandisa ubunzima be-wiring ohlangothini lwe-ac futhi kunzima ukukugcina. Olunye udaba oludinga ukuxazululwa yindlela yokuxhuma kugridi ngempumelelo. Indlela elula ukuxhuma ngokuqondile kugridi ngokusebenzisa isokhethi ajwayelekile e-AC Socket, okunganciphisa izindleko kanye nokufakwa kwamathuluzi, kepha imvamisa amazinga okuphepha wegridi angeke akuvumele. Ngokwenza kanjalo, inkampani yamandla ingahle iphazamise idivaysi yokuphehla amandla ixhumeke ngokuqondile ezisekelweni ezijwayelekile zabasebenzisi basendlini ezijwayelekile. Enye into ehlobene nokuphepha ukuthi ngabe i-solate transformer (imvamisa ephezulu noma imvamisa ephansi) iyadingeka, noma i-inverter engaguquki ivunyelwe. Leliinhlanganiselaisetshenziswa kakhulu ezindongeni zeglasi.
