Ukukhetha phakathi-kugridi,{1}}kugridi, kanye ne-hybrid akukhona ukuthi iyiphi isistimu "ehamba phambili." Kumayelana nokuthi iyiphi isistimu efana nendawo yakho, ibhajethi yakho, ukwakheka kwesilinganiso sokusetshenziswa kwakho, nokuthi kungakanani ukuphazamiseka ozimisele ukukubekezelela lapho ilanga lingashi.
-Kugridi (Igridi-Iboshiwe): Inketho Elula Neshibhe Kakhulu
Isistimu yelanga{{0}yegridi yegridi yelanga ixhuma ngqo kugridi yokusetshenziswayo. Amaphaneli elanga aphakela igridi-i-inverter eboshiwe, eguqula i-DC ibe i-AC futhi ivumelanise negridi. Uma amaphaneli akho ekhiqiza okungaphezu kwalokho okusetshenziswa yindlu yakho, amandla engeziwe ageleza kugridi. Uma udinga okungaphezu kokukhiqizwa kwamaphaneli akho, udweba kugridi.
Awekho amabhethri. Azikho izilawuli zokushaja. Asikho isipele ngesikhathi sokucisha.
Lelo phuzu lokugcina liyabamangaza abantu. Uma igridi yehla, igridi evamile{1}}isistimu eboshiwe iyavaleka - ngokomthetho. Kubizwa ngokuthi -ukuvikela isiqhingi, kudingwa yi-NEC 705 kanye ne-IEEE 1547. Uma isiguquli sakho sigcina ukuphakela amandla emigqeni eyehlisiwe, singasebenzisa ugesi osebenza ukubuyisela isevisi.

imibuzo ejwayelekile ukubuzwa
Ngingakwazi ukuqala ngegridi-eboshiwe bese ngengeza amabhethri kamuva?
Yebo - lena yindlela evamile yokuthuthukisa. Faka igridi-eboshiwe manje, bese wengeza isistimu yebhethri{3}ehlanganisiwe ye-AC uma isamba sesilinganiso sokulinganisa sehla noma uhlangabezana nokucisha. Qinisekisa ukuthi iphaneli yakho kagesi inesikhala se-inverter breaker yebhethri yesikhathi esizayo.
Mangaki amabhethri engiwadingayo-kugridi?
Qala ngokusebenzisa kwakho amandla kwansuku zonke (hlola inkokhiso yakho yensiza - isilinganiso sasekhaya sase-US sisebenzisa u-30 kWh/ngosuku). Phindaphinda ngezinsuku ezingu-2-3 zokuzimela. Hlukanisa ngokujula kwebhethri lokuphuma (90% ku-LiFePO4).
