1. Isizathu
Kungani i-Inverter yenzeka ngokweqile i-tripping noma ukuncishiswa kwamandla kwenzeka?
Kungaba ngolunye lwezizathu ezilandelayo:
1)Igridi yakho yasendaweni isivele isebenza ngaphandle kwemikhawulo ye-voltage ejwayelekile (noma izilungiselelo ezingalungile).Isibonelo, e-Australia, njengoba u-60038 ecacisa ama-230 volts njenge-voltage yegridi engomusomi nge. + 10%, -6% uhla, ngakho-ke umkhawulo ophezulu we-253V. Uma lokhu kunjalo-ke inkampani yakho yegridi yendawo inesibopho esingokomthetho sokulungisa ivola. Imvamisa ngokushintsha i-transformer yasendaweni.
2)Igridi yakho yasendaweni ingaphansi komkhawulo kanye nohlelo lwakho lwelanga, yize lifakwe kahle nakuwo wonke amazinga, ligxilisa igridi yendawo ngaphezulu komkhawulo we-tripping.Ama-terminals akho okukhipha ama-solar inverter axhumeke 'iphuzu lokuxhuma' ngegridi ngentambo. Le ntambo inokumelana kukagesi okwakha ama-voltage ngaphesheya kwentambo noma nini lapho i-inverter ithumela amandla ngokuthumela ugesi wamanje kugridi. Lokhu sikubiza ngokuthi 'ukukhuphuka kwamandla kagesi'. Lapho kuthekelisa kakhulu ama-voltage akhuphuka abonga umthetho we-ohm (v = IR), kanye nokuphikisana nokuphikisana kokukhuphuka kwamandla kagesi.
Isibonelo, e-Australia, i-Australia Standard 4777..1 Isho ukuthi ukukhuphuka kwamandla kagesi okukhulu ekufakweni kwelanga kufanele kube ngu-2% (4.6V).
Ngakho-ke ungahle ube nokufakwa okuhlangabezana naleli Zinga, futhi kukhuphuke ama-voltage we-4V ekuthekelweni okugcwele. Igridi yakho yasendaweni nayo ingahlangabezana nezinga futhi ibe ngo-252v.
Ngosuku oluhle lwelanga lapho kungekho muntu ekhaya, uhlelo lwathumela cishe yonke into kwigridi. I-voltage icindezelwe kuze kufike ku-252v + 4V = 256V isikhathi esingaphezu kwemizuzu eyi-10 kanye nohambo lwe-inverter.
3)Ukuphakama kwe-voltage okuphezulu phakathi kwe-inverter yakho yelanga kanye negridi ingaphezulu kwe-2% ephezulu kwiZinga,Ngoba ukumelana nentambo (kufaka phakathi noma yikuphi ukuxhumana) kuphezulu kakhulu. Uma lokhu kunjalo-ke isifaki bekufanele selulekele ukuthi i-AC yakho ikwazi ukuthuthukiswa kwegridi ngaphambi kokuba ilanga lingafakwa.
4) Udaba lwe-Hernter Hardware.
Uma i-voltage yegridi elinganiselwe ihlala iphakathi kwebanga, kepha i-inverter ihlala inephutha lokuqamba amaphutha noma ngabe uhla lwamandla kagesi luwukuthi, kufanele kube yinkinga ye-Hardware ye-inverter, kungenzeka ukuthi izimali zilimele.
2. Ukuxilongwa
Hlola i-grid Voltage yakho ukuze uvivinye i-GRID Voltage Yakho yeGridi, kufanele kulinganiswe ngenkathi uhlelo lwakho lwelanga luxhaswa. Ngaphandle kwalokho i-voltage yakho isilinganiso izothinteka ohlelweni lwakho lwelanga, futhi awukwazi ukubeka icala kugridi! Udinga ukufakazela ukuthi i-grid voltage iphakeme ngaphandle kohlelo lwakho lwelanga lokusebenza. Kufanele futhi uphendule yonke imithwalo emikhulu endlini yakho.
Kufanele futhi kulinganiswe ngosuku olunelanga nxazonke ntambama - ngoba lokhu kuzobhekwa ukukhuphuka kwamandla kagesi okubangelwa yiluphi olunye izinhlelo zonozungezilanga okuzungezile.
Okokuqala - qopha ukufundwa okusheshayo nge-multimeter. I-sparky yakho kufanele ithathe ukufundwa kwamandla asheshayo ebhodini eliphambili. Uma i-voltage inkulu kune-voltage elinganiselwe, bese ithathe isithombe se-multimeter (mhlawumbe nge-solar supply main switch endaweni efanelekile esithombeni esifanayo) bese uyithumela eMnyangweni Wezinga Wamandla Wezinkampani zeGridi.
Okwesibili - Qopha isilinganiso semizuzu eyi-10 nge-logger ye-voltage. I-sparky yakho idinga i-logger ye-voltage (ie fluke vr1710) futhi kufanele ilinganise iziqongo eziyi-10 zamamitha ayi-10 nge-solar yakho nemithwalo emikhulu icishiwe. Uma isilinganiso sesingaphezulu kwe-voltage elinganiselwe bese sithumela idatha erekhodiwe nesithombe sokusetha kokulinganisa - futhi okukhombisa ukucisha i-solar Supply Main Valive.
Uma noma yikuphi kwalezi zivivinyo ezingenhla ezingenhla 'zihle' zicindezela inkampani yakho yegridi ukulungisa amazinga akho e-voltage.
Qinisekisa ukwehla kwamandla kagesi ekufakweni kwakho
Uma izibalo zibonisa ukukhuphuka kwamandla kagesi ezingaphezu kuka-2% kuzodingeka uthuthukise i-ac cabsing kusuka ku-inverter yakho endaweni yokuxhumeka kwegridi ukuze izintambo zingamafutha (izintambo ezinamafutha = ukumelana okuphansi).
Isinyathelo sokugcina - ukukala ukukhuphuka kwamandla kagesi
1. Uma i-voltage yakho yegridi ilungile futhi izibalo ze-voltage Rise zingaphansi kwe-2% lapho-ke sparky yakho idinga ukukala le nkinga ukuqinisekisa ukubalwa kwama-voltage Rise:
2. Nge-PV off, nayo yonke eminye imibuthano yokulayisha icishiwe, ukukala i-no-volul voltage eshintshile.
I-3. Faka isicelo somthwalo owodwa owaziwayo isib. I-heater noma i-oven / ama-hotplates futhi ulinganise ukudweba kwamanje kuma-actives, ungathathi hlangothi
4. Kulokhu ungakwazi ukubala i-voltage Drop / RED kwi-MAIN COMCHERER MAIN nesensizakalo.

3. Isiphetho
Izinyathelo ezilandelayo
Manje kufanele wazi ukuthi yini inkinga yakho.
Uma kuyinkinga # 1- I-Grid Voltage ephezulu kakhulu--ke leyo yinkinga yenkampani yakho yegridi. Uma ubathumelela bonke ubufakazi engibaphakamisile bazophoqeleka ukukulungisa.
Uma kuyinkinga # 2- Igridi ilungile, ukukhuphuka kwamandla kagesi kungaphansi kwe-2%, kepha kusahambela lapho izinketho zakho zithi:
1. Ngokuya yinkampani yakho yegridi ungavunyelwa ukuthi ushintshe i-Inverter 10 imizuzu ajwayelekile kagesi umkhawulo wenani elivunyelwe (noma uma unenhlanhla enkulu kakhulu). Thola ukuthi kukhanyeke kwakho ukuze uhlole nenkampani yegridi uma uvunyelwe ukwenza lokhu.
2. Uma i-inverter yakho inemodi ye- "Volt / Var" (iningi lanamuhla lenziwa) - bese ubuza isifakeli sakho ukuze ikwazi ukwenza le modi ngamaphoyinti wakho wegridi anconyelwe yinkampani yakho yegridi yasendaweni - lokhu kunganciphisa ukugcwala kwe-voltage.
3. Uma lokho kungenzeki ngaleso sikhathi, uma unesigaba 3, ukuthuthukela esigabeni sesigaba esingu-3 esivame ukuxazulula inkinga - njengoba ukunyuka kwamandla kagesi kusakazeka ngaphezulu kwezigaba ezi-3.
4. Ngaphandle kwalokho ubheke ukuthuthukisa amakhekhe akho e-AC kugridi noma ukhawulele amandla okuthekelisa wohlelo lwakho lwelanga.
Uma kuyinkinga # 3- I-MAX VOLTAGE YIBA I-2% - khona-ke uma kungukufakwa kwakamuva kubukeka sengathi ukufaka kwakho akukufaki uhlelo kwiZinga. Kufanele ukhulume nabo futhi usebenze ikhambi. Kuzofaka kakhulu ukuthuthukisa i-AC kufinyelela kugridi (sebenzisa izintambo ezinamafutha noma ukunciphisa ikhebula phakathi kwe-Inverter ne-Grid Connection Point).
Uma kuyinkinga # 4- Inkinga yehadiwe ye-Inverter. Shayela ukwesekwa kobuchwepheshe ukunikela ngokubuyiselwa.
