1. Ukuguqulwa kwelahleko ephantsi
Enye yeempawu ezibaluleke kakhulu ze-inverter kukuguqulwa kwayo kakuhle, ixabiso elimele umlinganiselo wamandla afakwe xa i-current ngqo ibuyiswa njenge-alternating current, kwaye izixhobo zanamhlanje zisebenza malunga ne-98%.
2. Ukulungiswa kwamandla
Ijika leempawu zamandla kwimodyuli yePV ixhomekeke kubungakanani obukhulu kunye nobushushu bemodyuli, ngamanye amazwi, kumaxabiso aguqukayo imini yonke, ke ngoko, i-inverter kufuneka ifumane kwaye iqhubeke igcina eyona ilungileyo kumandla. ijika lophawu.indawo yokusebenza ukuze ukhuphe amandla aphezulu kwimodyuli yePV kwimeko nganye.
3. Ukubeka iliso kunye noKhuseleko
Ngakolunye uhlangothi, i-inverter ibeka iliso ekuveliseni amandla ombane we-photovoltaic, kwaye ngakolunye uhlangothi, iphinda ibeke iliso kwigridi edibeneyo.Ngoko ke, ukuba kukho ingxaki kwigridi, kufuneka ikhuphe ngokukhawuleza isityalo kwigridi ngenxa yezizathu zokhuseleko, kuxhomekeke kwiimfuno zomqhubi wendawo.
Ngaphezu koko, kwiimeko ezininzi, i-inverter ixhotywe ngesixhobo esinokuphazamisa ngokukhuselekileyo ukuhamba kwangoku kwiimodyuli ze-PV.Ekubeni imodyuli ye-PV ihlala isebenza xa ikhupha ukukhanya, ayikwazi ukucima.Ukuba iintambo ze-inverter zinqanyuliwe ngexesha lokusebenza, ii-arcs ezinobungozi zinokuqulunqa kwaye ezi ngqungquthela aziyi kucinywa ngumbane othe ngqo.Ukuba i-breaker circuit ihlanganiswe ngokuthe ngqo kwi-converter frequency, ukufakela kunye nomsebenzi we-wiring unokunciphisa kakhulu.
4. Unxibelelwano
I-interface yonxibelelwano kwi-converter frequency ivumela ukulawula kunye nokubeka iliso kuzo zonke iiparamitha, idatha yokusebenza kunye nesiphumo.Ngonxibelelwano lwenethiwekhi, i-industrial fieldbus efana ne-RS 485, kunokwenzeka ukubuyisela idatha kunye nokuseta iiparitha kwi-inverter.Kwiimeko ezininzi, idatha ibuyiswa nge-logger yedatha eqokelela idatha kwii-inverters ezininzi kwaye, ukuba ziyimfuneko, idlulisela kwi-portal yedatha ye-intanethi yamahhala.
5. Ulawulo lobushushu
Iqondo lokushisa kwi-inverter case lichaphazela ukusebenza kakuhle kokuguqulwa, ukuba ukunyuka kukhulu kakhulu, i-inverter kufuneka inciphise amandla, kwaye kwezinye iimeko amandla emodyuli akhoyo akakwazi ukusetyenziswa ngokupheleleyo.Ngakolunye uhlangothi, indawo yokufakela ichaphazela ukushisa - indawo epholileyo eqhubekayo ifanelekile.Ngakolunye uhlangothi, kuxhomekeke ngokuthe ngqo ekusebenzeni kwe-inverter: nokuba i-98% esebenzayo ithetha i-2% yokulahlekelwa kwamandla.Ukuba amandla esityalo ali-10 kW, amandla obushushu aphezulu asengama-200 W.
6. Ukhuseleko
Izindlu zemozulu, ngokufanelekileyo kunye neklasi yokukhusela i-IP 65, ivumela i-inverter ukuba ifakwe ngaphandle kuyo nayiphi na indawo efunwayo.Izinto eziluncedo: Okukhona ukufutshane kwiimodyuli ezinokuthi zifakwe kwi-inverter, kancinci uya kuchitha kwiintambo ze-DC eziduru kakhulu.
