Nekuda kwekusiyana kwezvivakwa, zvinozotungamira mukusiyana-siyana kwekuisa solar panel. Kuti uwedzere kushandurwa kwesimba rezuva uchifunga nezve kutaridzika kwakanaka kwechivako, izvi zvinoda kusiyanisa kwema inverters edu kuti tiwane nzira yakanakisa yesimba rezuva. Kutendeuka. Iyo inonyanya kuzivikanwa solar inverter nzira munyika ndeye: centralized inverters, tambo inverters, akawanda-tambo inverters uye component inverters. Iye zvino tichaongorora mashandisirwo emamwe ma inverters.
Centralized inverters anowanzo shandiswa mumasisitimu ane hombe photovoltaic magetsi zviteshi (》10kW). Mazhinji akafanana photovoltaic tambo dzakabatana kune iyo DC yekupinza yeiyo yakafanana centralized inverter. Kazhinji, matatu-chikamu IGBT simba modules anoshandiswa kune yakakwirira simba. Simba rezasi rinoshandisa munda-effect transistors uye DSP inoshandura controller kuvandudza kunaka kweiyo inogadzirwa simba remagetsi, zvichiita kuti ive pedyo zvakanyanya kune sine wave ikozvino. Chinhu chikuru ndeyesimba repamusoro uye mutengo wakaderera weiyo system. Zvisinei, iyo inokonzerwa nekufananidza kwe photovoltaic strings uye shading chikamu, zvichiita kuti kushanda uye simba rekugadzirisa kwese photovoltaic system. Panguva imwecheteyo, kuvimbika kwekugadzirwa kwemagetsi kwese photovoltaic system kunokonzerwa nehutano husina kunaka hwekushanda kwe photovoltaic unit group. Iyo yazvino tsvakiridzo dhairekitori kushandiswa kwenzvimbo vector modulation control uye kuvandudza kweiyo inverter topology yekubatanidza kuwana hunyanzvi hwepamusoro pasi pemamiriro emutoro.
PaSolarMax centralized inverter, unogona kubatanidza photovoltaic array interface bhokisi kutarisa yega yega photovoltaic windsurfing tambo. Kana imwe yetambo isingashande zvakanaka, hurongwa huchaendesa ruzivo urwu kune mutungamiriri ari kure Panguva imwecheteyo, tambo iyi inogona kumiswa nechekure, kuitira kuti kukundikana kwetambo ye photovoltaic strings irege kuderedza uye kukanganisa basa uye kubuda kwesimba kwese photovoltaic system.
String inverters dzave dzinonyanya kufarirwa inverters mumusika wepasirese. Iyo tambo inverter yakavakirwa pane modular pfungwa. Imwe neimwe photovoltaic tambo (1kW-5kW) inopfuura nepakati inverter, ine yakanyanya simba peak yekutevera kumagumo eDC, uye yakabatanidzwa mukufanana kumagumo eAC. Mazhinji mahombe emagetsi ephotovoltaic anoshandisa tambo inverters. Iyo inobatsira ndeyekuti haina kukanganiswa nemodule misiyano uye mimvuri pakati petambo, uye panguva imwechete inoderedza iyo yakakwana yekushanda poindi ye photovoltaic modules.
Kusiyana neiyo inverter, nekudaro kuwedzera huwandu hwekugadzira magetsi. Aya mabhenefiti ehunyanzvi haangodzikisi mutengo weiyo system, asiwo anowedzera kuvimbika kwehurongwa. Panguva imwecheteyo, pfungwa ye "tenzi-muranda" inotangwa pakati pezvisungo, kuitira kuti kana tambo imwe chete yesimba remagetsi isingagoni kuita imwe inverter kushanda muhurongwa, seti dzakawanda dze photovoltaic strings dzakabatanidzwa pamwe chete, uye imwe kana vakawanda vavo vanogona kushanda. , Kuitira kugadzira mamwe magetsi. Pfungwa yazvino ndeyekuti inverters yakati wandei inoumba "timu" kutsiva iyo "tenzi-muranda" pfungwa, iyo inoita kuti kuvimbika kweiyo system kuenderere mberi. Parizvino, transformerless tambo inverters yakatungamira.
Multi-string inverter inotora zvakanakira centralized inverter uye tambo inverter, inodzivirira kukanganisa kwayo, uye inogona kuiswa kune photovoltaic magetsi zviteshi zvekilowatts akati wandei. Mune iyo yakawanda-tambo inverter, akasiyana ega ega simba peak tracking uye DC-to-DC converters anosanganisirwa. Aya maDC anoshandurwa kuita AC simba neyakajairwa DC-ku-AC inverter uye yakabatana kune grid. Yakasiyana yakayerwa kukosha kweiyo photovoltaic tambo (senge: akasiyana akayerwa simba, akasiyana nhamba yezvikamu mutambo imwe neimwe, vakasiyana vagadziri vezvikamu, nezvimwewo), mafotovoltaic modules ehukuru hwakasiyana kana hunyanzvi hunyanzvi, uye tambo dzeakasiyana nzira (senge : Mabvazuva, Maodzanyemba neMadokero), makona akasiyana-siyana kana mimvuri, inogona kubatanidzwa kune yakajairwa inverter, uye tambo imwe neimwe iri kushanda pamasimba avo epamusoro. peak.
Panguva imwecheteyo, kureba kwetambo yeDC kunoderedzwa, mumvuri wekuita pakati pematambo uye kurasikirwa kunokonzerwa nekusiyana pakati petambo kunoderedzwa.
The component inverter ndeyekubatanidza imwe neimwe photovoltaic chikamu kune inverter, uye chikamu chimwe nechimwe chine yakaparadzana yepamusoro peak tracking yemagetsi, kuitira kuti chikamu uye inverter zvienderane zviri nani. Inowanzo shandiswa mu50W kusvika 400W photovoltaic simba zvidyarwa, iyo yakazara inoshanda yakaderera pane tambo inverters. Sezvo yakabatanidzwa mukuenderana ku AC, izvi zvinowedzera kuoma kweiyo wiring padivi re AC uye zvakaoma kuchengetedza. Imwe nyaya inoda kugadziriswa ndeye nzira yekubatanidza kune grid zvakanyanya. Nzira iri nyore ndeyekubatanidza zvakananga kune grid kuburikidza neyakajairwa AC socket, iyo inogona kuderedza mutengo uye kuisirwa kwemidziyo, asi kazhinji chengetedzo yegridi inogona kusabvumira. Mukuita izvi, kambani yemagetsi inogona kuramba kuti mudziyo wekugadzira magetsi wakabatana zvakananga kune zvakajairwa zvigadziko zvevashandisi vemba. Chimwe chinhu chine hukama nekuchengetedza ndechekuti yekuzviparadzanisa transformer (yakakwirira frequency kana yakaderera frequency) inodiwa, kana isina transformer inverter inobvumidzwa. Izviinverterinonyanya kushandiswa mugirazi machira emadziro.
