Inverter pa Grid
R3 Chidziwitso
RENAC R3 Note Series inverter ndi imodzi mwazinthu zabwino kwambiri zomwe zimapezeka m'magawo okhala ndi malonda ndi mphamvu zake zaukadaulo, zomwe zimapangitsa kuti ikhale imodzi mwazinthu zopanga kwambiri pamsika. Ndikuchita bwino kwambiri kwa 98.5%, kuchulukitsitsa kopitilira muyeso komanso kuchulukitsitsa, R3 Note Series ikuyimira kusintha kwakukulu pamakampani osinthira magetsi.

Mafunso Ogwirizana
- 1.Inverter ikuwonetsa cholakwika cha gridi ndikuwonetsa uthenga wolakwika ngati cholakwika chamagetsi "Grid Volt Fault" kapena cholakwika chafupipafupi "Grid Freq Fault" "Grid Fault"?
Chifukwa cha zomwe zachitika:
Ma voliyumu ndi mafupipafupi a gridi yamagetsi ya AC alibe mulingo wabwinobwino.
Yankho:
Yezerani ma voliyumu ndi ma frequency a gridi yamagetsi ya AC ndi zida zoyenera za multimeter, ngati zili zachilendo, dikirani kuti gridi yamagetsi ibwerere mwakale. Ngati voteji ya gridi ndi ma frequency ndizabwinobwino, zikutanthauza kuti dera lozindikira inverter ndilolakwika. Mukayang'ana, choyamba chotsani kulowetsa kwa DC ndi kutulutsa kwa AC kwa inverter, ndipo mulole inverter izimitse kwa nthawi yoposa 30min kuti muwone ngati dera lingathe kuchira palokha, ngati lingathe kuchira palokha, mukhoza kupitiriza kugwiritsa ntchito, ngati silingachiritsidwe, mukhoza kulankhulana.Renackwa kukonzanso kapena kusintha. Mayendedwe ena a inverter, monga inverter main board circuit, dera lodziwikiratu, dera lolumikizana, dera lozungulira, ndi zolakwika zina zofewa, angagwiritsidwe ntchito kuyesa njira yomwe ili pamwambapa kuti awone ngati atha kuchira okha, kenako ndikuwongolera kapena kuwasintha ngati sangathe kuchira okha.
- 2.Kuchuluka kwamagetsi otulutsa mbali ya AC, kuchititsa kuti inverter itseke kapena kusokoneza chitetezo?
Chifukwa cha zomwe zachitika:
Makamaka chifukwa cholepheretsa gridi ndi yayikulu kwambiri, pomwe mbali ya ogwiritsa ntchito PV yogwiritsa ntchito mphamvu ndi yaying'ono kwambiri, kutulutsa kwamphamvu kumakhala kokwera kwambiri, zomwe zimapangitsa kuti inverter AC mbali yamagetsi yotulutsa ikhale yokwera kwambiri!
Yankho:
(1) Wonjezerani waya wa waya wa chingwe chotulutsa, kukula kwa chingwe, kuchepetsa kutsekeka. Kuchuluka kwa chingwe, kutsika kwa impedance.
(2) Inverter ili pafupi kwambiri ndi malo olumikizidwa ndi gridi, yayifupi chingwe, kutsika kwa impedance. Mwachitsanzo, kutenga 5kw gululi olumikizidwa inverter mwachitsanzo, kutalika kwa AC linanena bungwe chingwe mkati 50m, mukhoza kusankha dera mtanda gawo la 2.5mm2 chingwe: kutalika 50 - 100m, muyenera kusankha mtanda-gawo la 4mm2 chingwe: kutalika kuposa 100m -6mm2 gawo chingwe chingwe.
- 3.DC mbali athandizira voteji overvoltage Alamu, zolakwa uthenga "PV Overvoltage" anasonyeza?
Chifukwa cha zomwe zachitika:
Ma module ambiri amalumikizidwa motsatizana, zomwe zimapangitsa kuti voteji yolowera mbali ya DC ipitirire mphamvu yayikulu yogwiritsira ntchito inverter.
Yankho:
Malinga ndi kutentha kwa ma module a PV, kutsika kwa kutentha kozungulira, kumapangitsa kuti magetsi atuluke. Ndi bwino sintha chingwe voteji osiyanasiyana malinga inverter datasheet. Mumtundu uwu wamagetsi, mphamvu ya inverter ndiyokwera kwambiri, ndipo inverter imatha kukhalabe ndi mphamvu yoyambira mphamvu pamene kuwala kumakhala kochepa m'mawa ndi madzulo, ndipo sikudzachititsa kuti magetsi a DC apitirire malire apamwamba a inverter voteji, zomwe zidzatsogolera ku alamu ndi kutseka.
