Inverter pa Grid
R3 Max
PV inverter R3 Max mndandanda, magawo atatu inverter yogwirizana ndi mapanelo akulu a PV, imagwiritsidwa ntchito kwambiri pamakina amalonda a PV ndi mafakitale akuluakulu apakati a PV. ili ndi chitetezo cha IP66 komanso kuwongolera mphamvu zamagetsi. Imathandizira kuchita bwino kwambiri, kudalirika kwakukulu, komanso kuyika kosavuta.

Koperani Zambiri Kanema wa Zamalonda
Mafunso Ogwirizana
- 1.Chifukwa chiyani "SPI Fault" ikuwonetsera pawindo la inverter?
Chifukwa cha zomwe zachitika:
Choyambitsa cholakwika ichi ndi vuto la kulumikizana pakati pa ma CPU akulu ndi achiwiri a board control inverter.
Yankho:
(1)Ryambani inverter (muyenera kuletsa PV, gridi ya AC, ndi mabatire ndikuyatsanso).
(2) Ngati vuto likupitilira mutatha kuyambitsanso inverter, fufuzani ngati pulogalamu ya pulogalamu ya inverter control board ndiyolondola. Ngati sichoncho, yesani kuwotcha mu pulogalamuyo kachiwiri.
(3) Ngati vuto likupitilira mutatha kuwotcha pulogalamuyo, sinthani bolodi yowongolera.
- 2.Inverter ikuwonetsa cholakwika cha gridi ndikuwonetsa uthenga wolakwika ngati vuto lamagetsi "Grid Volt Fault" kapena zolakwika pafupipafupi "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.
- 3.Kuchuluka kwa magetsi ku 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.
