1. Isizathu
Kutheni le nto i-iniverter yenzekile ngaphezulu kokuhamba okanye ukuncitshiswa kwamandla okwenzekayo?
Isenokuba sesinye sezi zizathu zilandelayo:
1)Igridi yakho yendawo sele isebenza ngaphandle kwemida ye-voltage yomgangatho (okanye useto lwemigaqo engalunganga).Umzekelo, e-Australia, nge-60038 ichaza i-230 volts njengevolthi yegridi eyi-a. + I-10%, -6% i-%, ngoko umda ophezulu we-253v. Ukuba le yimeko ke inkampani yakho yegridi yendawo inembopheleleko esemthethweni yokulungisa i-voltage. Ngokwesiqhelo ngokuguqula i-transformer yendawo.
2)Igridi yakho yendawo iphantsi komda kunye nenkqubo yakho yelanga, nangona ifakwe ngokuchanekileyo nakuyo yonke imigangatho, ityhila igridi yomhlaba ngaphezulu komda wokuhamba.I-TheAREP yakho ye-Inverter yelanga iqhagamshelwe 'kwinqaku loqhagamshelo' kunye negridi ngentambo. Le cable ichasile i-voltical edala intambo kwintambo naphi na apho i-insuverter ikhutshelwa ngaphandle ngokuthumela umbane kwigridi. Oku sikubiza ngokuba 'vuka'. Okukhona uninzi lwelanga lukhuphela i-solar inkulu i-voltage inyuka inkosi yomthetho ka-Ohm (v = ir), kwaye iphakamile ichasi i-cabling inkulu i-cableger inyuka.
Umzekelo, eOstreliya, umgangatho wama-4777.1 uthi eyona voltage inyuka kwindawo yokufakelwa ilanga kufuneka ibe yi-2% (4.6V).
Ke unokuba nofakelo oluhlangabezana nalo mgangatho, kwaye une-voltage inyuka i-4V ngokuthumela ngokupheleleyo. Igridi yakho yendawo inokuhlangabezana nemigangatho kwaye ibe ngama-252v.
Ngosuku olulungileyo lwelanga xa kungekho mntu ekhaya, inkqubo ithumela ngaphandle yonke into kwigridi. I-voltage ityhutywe ukuya kuthi ga kwi-252v + 4v = 256v kangangemizuzu eli-10 kunye neehambo ze-inverter.
3)Elona tyala liphezulu le-voltage inyuka phakathi kwe-Inirter yakho yelanga kwaye i-grid ingaphezulu kwe-2% iphezulu kumgangatho,Kuba ukuxhathisa kwintambo (kubandakanya naluphi na unxibelelwano) luphezulu kakhulu. Ukuba le yimeko emva koko umfaki ebekufanele ukuba akucebise ukuba i-cabling yakho ye-AC kwigridi ifuna ukuphuculwa ngaphambi kokuba ifakwe i-solar.
I-4) Umcimbi we-inverter hardver.
Ukuba i-voltage edikini ilinganiswe ngaphakathi koluhlu, kodwa i-inverter ihlala inesifo sokuhamba ngempazamo yendlela yokuhamba kwe-voltage, nokuba ingaba i-Inverwage Genure ye-Inureter, inokuba i-Igbst yonakalisiwe.
2. Ukufumanisa isifo
Vavanya i-voltage yakho ye-grid ukuvavanya i-voltage yakho ye-grid yendawo, kufuneka ilinganiswe ngelixa inkqubo yakho yelanga ixhaswe. Ngaphandle koko i-voltage oyilinganisa iya kuchaphazeleka yinkqubo yakho yelanga, kwaye awungekhe ubeke ityala kwigridi! Kuya kufuneka ubonise ukuba i-voltage yegrid iphezulu ngaphandle kwenkqubo yakho yelanga isebenza. Kuya kufuneka uguqule yonke imithwalo emikhulu kwindlu yakho.
Ifanele ilinganiswe ngemini enelanga, njengoko oku kuyakuthatha ingqalelo i-voltage inyuka ibangelwa zezinye iinkqubo zelanga ezikungqongileyo.
Okokuqala-iRekhoda yokufunda ngokukhawuleza nge-multem. I-sparky yakho kufuneka ithathe i-voltaneal voltage kufunda kwibhodi ephambili yokutshintsha. Ukuba i-voltage inkulu kunevolthi encinci, emva koko thatha ifoto ye-Multimeter (ngokukhethekileyo i-switch eshiyiweyo yelanga kwindawo engekhoyo kwi-pidi engaphezulu) kwaye uyithumele kwiSebe leMigangatho ye-GRID yeGridi.
Okwesibini - Rekhoda umndilili we-10 we-10 ngelogger yevolthi. I-sparky yakho ifuna ilog yevolthi (okt i-vr1710) kwaye kufuneka ilinganise i-10 yemizuzu eyi-10 ye-Peapide ngelanga lakho kunye nemithwalo emikhulu ecinyiwe. Ukuba umndilili ungaphezulu kwe-voltage enesimiliweyo emva koko thumela idatha erekhodiweyo kunye nomfanekiso weseti yendlela yokuseta-ngokuphinda-phinda ibonisa i-solar yokuhambisa i-souse spect switch ciction icime.
Ukuba enye yeemvavanyo ezi-2 ezingasentla 'iyodwa inyanzelise inkampani yakho yeGridi ukulungisa amanqanaba akho eVoltige.
Qinisekisa ukuba i-voltage yehlile kufakelo lwakho
Ukuba ukubala kubonisa i-voltage inyuke ngaphezulu kwe-2% kuya kufuneka uphucule i-cabling ye-AC kwi-Inverter yakho kwindawo ye-Grid ukuya kwinqaku legridi ukuze iingcingo zityebile (i-nimo ebunzi).
Inyathelo lokugqibela-ilinganisa i-voltage inyuke
1. Ukuba i-voltage yakho ye-grid ilungile kwaye i-voltage inyuke ingaphantsi kwe-2%, i-sparky yakho ifuna ukulinganisa ingxaki ukubala i-voltage inyukele ukubala
2. Nge-PV ecinyiwe, kwaye yonke enye imijikelezo yemithwalo ngaphandle, ilinganisa iflogi ye-No-Umthwalo we-No-Umthwalo kwiSpecial Switch.
3. Sebenzisa umthwalo ongaziyo umthwalo omnye owaziwayo, umzekelo, i-heater okanye i-oveni / i-oveni kwaye ulinganise umzobo wangoku kwi-Assives, engathathi cala nakumhlaba kwaye kwi-voltage yonikezo.
4. Kule nto ungabala i-voltage phosa / vuka kumthengi ongenayo kunye nenkonzo.
I-5. Bala i-Line Candelo lokunganyangekiyo nge-OHM umthetho ukuze uthathe izinto ezinje ngeenyawo ezimbi okanye ukungathathi cala.
3. Ukuqukumbela
Amanyathelo alandelayo
Ngoku kuya kufuneka uyazi ukuba yintoni ingxaki yakho.
Ukuba yingxaki # 1-I-Grid Voltrage ephezulu kakhulu- yingxaki yenkampani yakho yegridi. Ukuba ubathumelela bonke ubungqina endizicebileyo ukuba baya kunyanzeleka ukuba bayilungise.
Ukuba yingxaki # 2-Igridi ilungile, ukunyuka kwe-voltage kungaphantsi kwe-2%, kodwa ikwahamba emva koko ukhetho lwakho zezi:
1. Kuxhomekeka kwinkampani yakho yegridi onokuthi uvunyelwe ukutshintsha umxholo we-Inverter Wieltiment umda kwixabiso elivumelekileyo (okanye ukuba unethamsanqa kakhulu). Fumana i-sparky yakho ukukhangela kwinkampani yeGridi ukuba uvunyelwe ukwenza oku.
2. Ukuba i-iniverter yakho ine "volt / volt / var" yenziwa) - emva koko icele ukuba le ndlela isebenze yinkampani yakho yegridi - oku kunganciphisa isixa se-voltage.
3. Ukuba akunakwenzeka ke, ukuba ubonelela ngenqanaba le-3, ukuphuculwa kwe-INTERNTER yesiGaba esi-3 kudla ngokusombulula umba- njengoko i-voltage inyuka ngaphezulu kwezigaba ezi-3.
4. Ngaphandle koko ujonga ukuphucula iintambo zakho ze-AC kwigridi okanye ukunciphisa amandla okuthumela kwelinye ilizwe kwiSolar System yakho.
Ukuba yingxaki # 3-Umbane ophakama ngaphezulu kwe-2% - ke ukuba lufake ukufaka inkangeleko yakho ijongeka ngathi ifakiwe yakho ayifakwanga le nkqubo kumgangatho. Kuya kufuneka uthethe nabo kwaye usebenze isisombululo. Kuya kubandakanya ukuphuculwa kokuphuculwa kwe-cbling kwigridi (Sebenzisa iingcingo ezityebileyo okanye ukufutshane intambo phakathi kwendawo ye-inverter kunye nendawo ye-GRED).
Ukuba yingxaki # 4-Ingxaki ye-inverter ye-inverter. Fowunela inkxaso yezobugcisa ukuze inike indawo.
