Amanqaku esicelo

1. Intshayelelo Ummiselo wase-Italiya ufuna ukuba zonke ii-inverters eziqhagamshelwe kwigridi ziqale zenze uvavanyo lwe-SPI.Ngeli xesha lokuzivavanya, i-inverter ijonga amaxesha ohambo kwi-voltage engaphezulu, ngaphantsi kwe-voltage, ngaphezulu kwe-frequency kunye naphantsi kwamaza-ukuqinisekisa ukuba i-inverter iyanqanyulwa xa ifunwa...

1. Yintoni ukunciphisa ubushushu?Ukunciphisa kukunciphisa okulawulwayo kwamandla e-inverter.Kumsebenzi oqhelekileyo, ii-inverters zisebenza kwindawo yazo yamandla aphezulu.Kule ndawo yokusebenza, umlinganiselo phakathi kwe-PV voltage kunye ne-PV yangoku iphumela kumandla aphezulu.Elona nqaku lamandla liphezulu litshintsha iingxaki...

Ngophuhliso lwetekhnoloji yemodyuli yeCell kunye ne-PV, itekhnoloji ezahlukeneyo ezifana ne-half cut cell, imodyuli ye-shingling, imodyuli yobuso be-bi-facial, i-PERC, njl njl.Amandla okuphuma kunye nokukhoyo kwimodyuli enye anyuke kakhulu.Oku kuzisa iimfuno eziphezulu zokuguqula...

Yintoni “impazamo yokuba wedwa”?Kwiinkqubo ze-photovoltaic ezine-transformer-less inverter, i-DC yodwa ukusuka kumhlaba.Iimodyuli ezinemodyuli yodwa enesiphene, iingcingo ezingakhuselekanga, izilungisi zamandla ezineziphene, okanye inverter yangaphakathi impazamo inokubangela ukuvuza kwangoku kweDC phantsi (PE - ikhusela ...

1. Isizathu Kutheni i-inverter isenzeka ukukhubeka ngaphezulu kwe-voltage okanye ukuncipha kwamandla kwenzeka?Isenokuba sesinye sezi zizathu zilandelayo: 1) Igridi yakho yendawo sele isebenza ngaphandle kwemida yombane oMgangatho wendawo (okanye useto olungalunganga lommiselo).Umzekelo, eOstreliya, i-AS 60038 ichaza i-230 volts njenge ...

Amazwe amaninzi ehlabathini asebenzisa ukunikezelwa komgangatho we-230 V (i-voltage yesigaba) kunye ne-400V (i-voltage yomgca) kunye neentambo ezingathathi hlangothi kwi-50Hz okanye i-60Hz.Okanye kusenokubakho ipateni yegridi yeDelta yothutho lwamandla kunye nokusetyenziswa kweshishini koomatshini abakhethekileyo.Kwaye njengesiphumo esihambelanayo, uninzi lwe-solar inverte ...

I-Solar Inverter Uluhlu lweMitya yoYilo Eli nqaku lilandelayo liza kukunceda ukubala ubuninzi / ubuncinane benani leemodyuli ngothotho lomtya xa uyila inkqubo yakho yePV.Kwaye ubungakanani be-inverter bubandakanya iinxalenye ezimbini, i-voltage, kunye nobungakanani bangoku.Ngexesha lokulinganisa i-inverter kufuneka uthathe ...

Kutheni le nto kufuneka sonyuse i-invert switching frequency?Esona siphumo siphezulu se-invert frequency: 1. Ngokunyuka kwe-invert frequency frequency, umthamo kunye nobunzima be-inverter buyancitshiswa, kwaye ubuninzi bamandla buphuculwe kakhulu, obunokunciphisa ngokufanelekileyo ukugcinwa, ...

Kutheni sidinga i-Export Limitation Feature 1. Kwamanye amazwe, imimiselo yendawo inciphisa ubungakanani beplanti yamandla ye-PV inokondliwa-ngaphakathi kwigridi okanye ingavumeli ukondla kuyo nayiphi na into, ngelixa ivumela ukusetyenziswa kwamandla e-PV ukuba azenzele.Ke ngoko, ngaphandle kweSisombululo soMda wokuThunyelwa ngaphandle, inkqubo yePV ayinakuba...
