N'afọ a, ihe ngosi El Niño nwere ike ime, ma ọ bụ oge okpomọkụ kachasị mma n'akụkọ ihe mere eme ga-ebute, nke ga-eweta ihe ịma aka siri ike na ụlọ ọrụ fotovoltaic.
1.1 Mmetụta nke elu okpomọkụ na components
Oke okpomọkụ ga-ebelata arụmọrụ na ndụ nke akụrụngwa, dị ka inductor, capacitors electrolytic, modul ike, wdg.
Inductance:N'ebe okpomọkụ dị elu, inductance dị mfe iji jupụta, na inductance jupụtara na ya ga-ebelata, na-eme ka ọnụ ọgụgụ dị elu nke arụ ọrụ dị ugbu a na-eme ka ọ dịkwuo elu, ma mebie ngwaọrụ ike n'ihi na ọ dị ugbu a.
Capacitor:Maka ndị na-ahụ maka electrolytic capacitors, ndụ ndụ nke ndị na-eme ihe electrolytic na-ebelata site na ọkara mgbe okpomọkụ ikuku na-ebili site na 10 Celsius. Aluminom electrolytic capacitors n'ozuzu na-eji okpomọkụ nso nke -25 ~+105C, na ihe nkiri capacitors n'ozuzu na-eji okpomọkụ nso nke -40 ~+105°C. Ya mere, obere inverters na-ejikarị capacitors ihe nkiri eme ihe iji meziwanye mgbanwe nke inverters na okpomọkụ dị elu.
Ndụ nke capacitors na okpomọkụ dị iche iche
modul ike:Ihe dị elu nke okpomọkụ, na-eme ka okpomọkụ nkwụsị nke mgbawa dị elu mgbe modul ike na-arụ ọrụ, nke na-eme ka modul buru nrụgide okpomọkụ dị elu ma na-ebelata ndụ ọrụ. Ozugbo okpomọkụ ahụ gafere oke okpomọkụ nkwụsịtụ, ọ ga-eme ka okpomọkụ nke modul.
1.2 Ntụsa ọkụ ọkụ inverter
The inverter nwere ike na-arụ ọrụ n'èzí na 45 Celsius C ma ọ bụ karịa okpomọkụ. Ntugharị ikpo ọkụ nke onye ntụgharị bụ ụzọ dị mkpa iji hụ na arụ ọrụ kwụsiri ike, nchekwa na ntụkwasị obi nke akụrụngwa eletrọnịkị ọ bụla na ngwaahịa n'ime okpomọkụ na-arụ ọrụ. Ebe nleba anya okpomọkụ nke inverter bụ nkwalite inductor, inverter inductor, na IGBT modul, na okpomọkụ na-esi n'èzí na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ. Ihe na-esonụ bụ usoro na-ebelata okpomọkụ nke GW50KS-MT:
Ngosipụta okpomọkụ na-ebili na ọdịda ibu usoro
1.3 Ewu mgbochi elu okpomọkụ atụmatụ
N'elu ụlọ ọrụ mmepụta ihe, okpomọkụ na-adịkarị elu karịa nke dị na ala. Iji gbochie inverter ka ọ ghara ikpughe na ìhè anyanwụ kpọmkwem, a na-etinyekarị ihe ntụgharị ahụ na ebe ndò ma ọ bụ na-agbakwụnye ihe mgbagwoju anya n'elu ihe ntụgharị ahụ. Ekwesiri iburu n'uche na a ga-edobe oghere maka ịrụ ọrụ na nrụzi n'ọnọdụ ebe ikuku inverter na-abanye ma na-apụ na ikuku na ikuku nke mpụga. Ndị na-esonụ bụ ihe inverter nwere ikuku aka ekpe na aka nri na ọpụpụ. Ọ dị mkpa idobere ohere zuru oke n'akụkụ abụọ nke onye ntụgharị, ma debe ebe kwesịrị ekwesị n'etiti anya anwụ na elu nke inverter.

Tihu igwe ebili mmiri

Eluigwe na oke mmiri ozuzo n'oge okpomọkụ.
2.1 Inverter Lightning na ihe nchebe mmiri ozuzo
Usoro nchebe ọkụ inverter:Akụkụ AC na DC nke inverter na-eji ngwaọrụ nchebe ọkụ dị elu, na kọntaktị akọrọ nwere ihe mkpuchi mkpuchi ọkụ, nke dị mma maka ndabere iji mara ọnọdụ kpọmkwem nke nchebe ọkụ.
Ihe mgbochi mmiri ozuzo na mgbochi corrosion:Onye ntụgharị ahụ na-anabata ọkwa nchebe IP66 dị elu yana ọkwa mgbochi corrosion C4&C5 iji hụ na onye ntụgharị ahụ na-aga n'ihu na-arụ ọrụ n'okpuru oke mmiri ozuzo.
Njikọ ụgha nke njikọ fotovoltaic, ntinye mmiri mgbe eriri ahụ mebiri emebi, na-eme ka obere sekit dị n'akụkụ DC ma ọ bụ nkwụsị ala, na-eme ka onye ntụgharị ahụ kwụsị. Ya mere, ọrụ nchọpụta DC arc nke inverter dịkwa oke mkpa.
2.2 Atụmatụ nchebe ọkụ (ihe owuwu) n'ozuzu ya
Mee ezigbo ọrụ nke sistemu ụwa, gụnyere ọdụ akụrụngwa na inverters.
Ihe nchebe ọkụ ọkụ na panel anyanwụ na inverter
Oge okpomọkụ nke mmiri ozuzo nwekwara ike ime ka ahịhịa tolite ma kpuchie ihe ndị mejupụtara ya. Mgbe mmiri ozuzo na-asachapụ ihe ndị ahụ, ọ dị mfe ime ka nchịkọta uzuzu dị n'akụkụ akụkụ nke ihe ndị ahụ, nke ga-emetụta ọrụ nhicha na-esote.
Na-arụ ọrụ dị mma na nyocha nke usoro, na-enyocha ihe mkpuchi na ọnọdụ mmiri mgbe niile nke njikọ fotovoltaic na eriri, chọpụta ma eriri mmiri na-agbanye n'ime mmiri ozuzo, na ma enwere ịka nká na mgbawa na mkpuchi mkpuchi eriri.
Igwe ọkụ fotovoltaic bụ ike ihu igwe niile. Okpomọkụ dị elu na égbè eluigwe n'oge okpomọkụ ewetala ihe ịma aka siri ike na ọrụ na mmezi nke ụlọ ọrụ fotovoltaic. Ijikọta inverter na n'ozuzu ike osisi imewe, Xiaogu na-enye aro na-ewu, ọrụ na mmezi, na-atụ anya na-enyere onye ọ bụla.
