Iinkqubo ze-photovoltaic zelanga zihlulwe kakhulu kwiinkqubo zokuvelisa amandla e-photovoltaic ngaphandle kwegridi kunye neenkqubo zokuvelisa amandla e-photovoltaic ezidityaniswe negridi.
1. Inkqubo yokuvelisa amandla e-off-grid photovoltaic iqulunqwe ikakhulu ngamacandelo eeseli zelanga, izilawuli, kunye neebhetri.Ukuba ufuna ukunika amandla kumthwalo we-AC, kufuneka kwakhona uqwalasele i-inverter ye-AC.
2. Inkqubo yokuvelisa amandla e-photovoltaic edityaniswe kwigridi ithetha ukuba umbane othe ngqo owenziwe ziimodyuli zelanga uguqulwa ube ngumbane otshintshanayo ohlangabezana neemfuno zegridi yamandla ombane ngokusebenzisa i-inverter eqhagamshelwe kwigridi kwaye emva koko iqhagamshelwe ngokuthe ngqo kwigridi yoluntu.
Umgaqo osebenzayo we-solar photovoltaic system:
Emini, phantsi kweemeko zokukhanya, iimodyuli zeeseli zelanga zivelisa amandla athile e-electromotive, kwaye uluhlu lweeseli zelanga zenziwa ngoluhlu kunye noxhulumaniso oluhambelanayo lweemodyuli, ukwenzela ukuba i-voltage ye-array ikwazi ukuhlangabezana neemfuno ze-voltage input. yenkqubo.Emva koko tshaja ibhetri ngokutshaja kunye nesilawuli sokukhupha, kwaye ugcine amandla ombane aguqulwe kumandla okukhanya.
Ebusuku, ipakethe yebhetri inika amandla okufakwa kwi-inverter.Ngomsebenzi we-inverter, amandla e-DC aguqulwa abe ngamandla e-AC, athunyelwa kwikhabhinethi yokusabalalisa amandla, kwaye amandla anikezelwa ngumsebenzi wokutshintsha kwekhabhinethi yokusabalalisa amandla.Ukukhutshwa kwepakethi yebhetri kulawulwa ngumlawuli ukuqinisekisa ukusetyenziswa okuqhelekileyo kwebhetri.Inkqubo yesikhululo samandla e-photovoltaic kufuneka kwakhona ibe nezixhobo zokukhusela umthwalo olinganiselweyo kunye nezixhobo zokukhusela umbane ukukhusela ukusebenza okugqithisiweyo kwezixhobo zenkqubo kunye nokuphepha ukubetha kombane, kunye nokugcina ukusetyenziswa ngokukhuselekileyo kwezixhobo zenkqubo.
Ukuqulunqwa kwenkqubo ye-photovoltaic yelanga:
1. Iiphaneli zelanga
Iphaneli yelanga yinxalenye ephambili yenkqubo ye-photovoltaic yelanga.Umsebenzi wepaneli yelanga kukuguqula amandla okukhanya kwelanga kumandla ombane, kwaye emva koko ukhuphe umsinga othe ngqo oza kugcinwa kwibhetri.Iipaneli zelanga enye yezona zinto zibalulekileyo kwiinkqubo ze-photovoltaic zelanga, kwaye izinga labo lokuguqulwa kunye nobomi benkonzo zizinto ezibalulekileyo ezibonisa ukuba iiseli zelanga zinexabiso lokusetyenziswa.
2. Umlawuli
Umlawuli welanga uqulunqwe yiprosesa ye-CPU ezinikeleyo, izixhobo ze-elektroniki, iziboniso, iibhubhu zamandla ezitshintshayo, njl.
3. Ibhetri
Umsebenzi we-accumulator kukugcina amandla ombane awenziwe yipaneli yelanga xa kukho ukukhanya, kwaye emva koko uyikhulule xa kufuneka.
4. Inverter
Isiphumo esithe ngqo samandla elanga ngokuqhelekileyo yi-12VDC, 24VDC, 48VDC.Ukuze unikeze amandla ombane kwizixhobo zombane ze-220VAC, amandla e-DC aveliswa yinkqubo ye-photovoltaic yelanga kufuneka aguqulwe abe ngumbane we-AC, ngoko kufuneka i-DC-AC inverter.
