Kutheni iiseli zeSolar zifuna i-Inverter?

Iiseli zeSolar zisisiseko sayo nayiphi na inkqubo yamandla elanga, kodwa azikwazi ukuvelisa umbane ngokwazo.Bafuna isiguquli sombane ukuguqula umbane othe ngqo (i-DC) abawuvelisayo ube ngumsinga otshintshanayo (AC), uhlobo lombane osetyenziselwa ukuphembelela amakhaya namashishini.

I-inverter sisixhobo esiguqula umbane we-DC ube ngumbane we-AC.Ikwenza oku ngokusebenzisa i-transformer, esisixhobo esonyusa okanye esinciphisa amandla ombane wombane.

I-transformer kwi-inverter inyusa amandla ombane ombane we-DC ukusuka kwiiseli zelanga ukuya kwinqanaba lombane we-AC osetyenziswa kumakhaya nakumashishini.

Iiseli zelanga zivelisa umbane we-DC, kodwa amakhaya amaninzi kunye namashishini asebenzisa umbane we-AC.Oku kungenxa yokuba umbane we-AC kulula ukuwuthumela kumgama omde kwaye unokusetyenziselwa ukunika amandla uluhlu olubanzi lwezixhobo.

Iiseli zelanga azikwazanga ukuvelisa umbane onokusetyenziswa ngokuthe ngqo kumakhaya kunye namashishini ngaphandle kwe-inverter.

Iintlobo zee-Inverters

Kukho iintlobo ezimbini eziphambili ze-inverters: i-grid-tie inverters kunye ne-off-grid inverters.

• Ii-inverters zegridiziqhagamshelwe kwigridi yombane.Bavumela abaninimzi ukuba basebenzise amandla elanga ukuhlawula amatyala abo ombane.Xa inkqubo yepaneli yelanga ivelisa umbane ongaphezulu kunoko kusetyenziswa ekhaya, umbane ogqithisileyo ubuyiselwa kwigridi.Xa iipaneli zelanga zingavelisi umbane owaneleyo, indlu itsala umbane kwigridi.
• Ii-inverters ze-off-grid azixhunyiwe kwigridi yombane.Bagcina umbane oveliswa ziipaneli zelanga kwiibhetri.Oku kuvumela abaninimzi ukuba basebenzise amandla elanga naxa ilanga lingaphumi.

Ukukhetha i-Inverter

Xa ukhetha i-inverter, kukho izinto ezimbalwa zokuqwalasela, kubandakanywa ubungakanani benkqubo yamandla elanga, uhlobo lwe-inverter, kunye neempawu ze-inverter.

Ubungakanani benkqubo yamandla elanga bumisela ubungakanani be-inverter efunekayo.Inkqubo enkulu yamandla elanga iya kufuna inverter enkulu.

Makhe siqwalasele umzekelo: Masithi une-5 kWinkqubo yamandla elangaeziquka 20 solar panels, ngalinye ukuvelisa 250 watts.Kule meko, uya kufuna isiguquli-mandla esinamandla angama-5 kW ubuncinci ukujongana nemveliso yamandla ewonke.

Ubungakanani be-inverter kufuneka bufanise okanye bugqithise kancinane ukukhutshwa kwamandla aphezulu kwiipaneli zelanga ukuqinisekisa ukusebenza kakuhle kunye nokuthintela ukugqithiswa.

2. I-grid-tie okanye i-off-grid

Uhlobo lwe-inverter luxhomekeke ekubeni inkqubo yamandla elanga ixhunyiwe kwigridi yombane okanye cha.Ii-inverters ze-grid-tie ziyafuneka kwiinkqubo zamandla elanga eziqhagamshelwe kwigridi yombane.

Ngaphandle kwegridiii-inverters ziyafuneka kwiinkqubo zamandla elanga ezingaqhagamshelwanga kwigridi yombane.

Iimpawu ze-inverter ziquka inani leesekethe eziphumayo, amandla aphezulu ombane, kunye nokusebenza kakuhle kwe-inverter.Inani leesekethe zemveliso limisela ukuba zingaphi izixhobo ezinokunikwa amandla yi-inverter.

Ubuninzi bemveliso yamandla bumisela ubungakanani bombane onokuthi uvelise i-inverter.

Ukusebenza kakuhle kwe-inverter kumisela ukuba ungakanani umbane oveliswa yi-solar panel usetyenziselwa izixhobo zombane.

I-inverter yinxalenye ebalulekileyo yayo nayiphi na inkqubo yamandla elanga.Iguqula umbane weDC oveliswe ziiseli zelanga ube ngumbane we-AC, onokunika amandla amakhaya kunye namashishini.

Kukho iintlobo ezimbini eziphambili ze-inverters: i-grid-tie inverters kunye ne-off-grid inverters.Xa ukhetha i-inverter, qwalasela ubungakanani benkqubo yakho yamandla elanga, uhlobo lwe-inverter, kunye neempawu ze-inverter.
