Inkcazelo emfutshane:
I-photovoltaic off grid inverter sisixhobo sokuguqula amandla esonyusa amandla e-DC ngokutyhala kunye nokutsala, kwaye emva koko siyiguqulele kumandla we-220V AC ngokusebenzisa ibhulorho yokuguqula i-SPWM sine-pulse ububanzi bokumodulation ubuchwepheshe.
Igama elipheleleyo lomlawuli weMPPT ngu "Maximum Power Point Tracking" umlawuli welanga, oyimveliso ephuculweyo yokutshaja kwelanga kunye nezilawuli zokukhupha.Umlawuli weMPPT unokubona i-voltage yesizukulwana sepaneli yelanga ngexesha langempela kwaye ulandele i-voltage ephezulu kunye nexabiso langoku (VI), okwenza inkqubo ihlawule ibhetri kwimveliso yamandla aphezulu.Ukusetyenziswa kwiinkqubo ze-photovoltaic zelanga, ukulungelelanisa umsebenzi weepaneli zelanga, iibhetri, kunye nemithwalo yingqondo yeenkqubo ze-photovoltaic.Ubuninzi benkqubo yokulandelela indawo yombane yinkqubo yombane elungisa imeko yokusebenza kweemodyuli zombane ukwenzela ukuba iipaneli ze-photovoltaic zikhuphe umbane ongaphezulu.Iyakwazi ukugcina ngokufanelekileyo umbane othe ngqo owenziwe ngamapaneli elanga kwiibhetri, ukusombulula ngokufanelekileyo ingxaki yokuhlala kunye nombane woshishino kwiindawo ezikude kunye neendawo zokutyelela ezingenako ukugqunywa ngamagridi ombane aqhelekileyo, ngaphandle kokuvelisa ukungcola kokusingqongileyo.
I-Photovoltaic off grid inverters ifanelekile kwiinkqubo zamandla, iinkqubo zonxibelelwano, iinkqubo zikaloliwe, iinqanawa, izibhedlele, iindawo zokuthenga, izikolo, ngaphandle kunye nezinye iindawo.Iyakwazi ukuqhagamshelwa kwi-mains ukutshaja ibhetri.Inokusetwa njengebhetri ephambili okanye ingundoqo ephambili.Ngokuqhelekileyo, i-inverters yegridi kufuneka idibaniswe kwiibhetri kuba ukuveliswa kwamandla e-photovoltaic akuzinzile kwaye umthwalo awuzinzile.Ibhetri iyafuneka ukulinganisa amandla.Nangona kunjalo, ayizizo zonke ii-photovoltaic off grid inverters ezifuna uqhagamshelo lwebhetri.
Inokwenziwa ngokwezifiso
