Njengoba izinhlelo zokugcina amandla elanga ziya ngokuya zithandwa, abantu abaningi bajwayelene nemingcele evamile yama-inverter okugcina amandla.Kodwa-ke, asekhona amapharamitha okufanele aqondwe ngokujulile.Namuhla, ngikhethe amapharamitha amane avame ukunganakwa lapho kukhethwa ama-inverter okugcina amandla kodwa abalulekile ekwenzeni ukukhetha okufanele komkhiqizo.Ngithemba ukuthi ngemva kokufunda lesi sihloko, wonke umuntu uzokwazi ukukhetha okufaneleka kakhulu lapho ebhekene nezinhlobonhlobo zemikhiqizo yokugcina amandla.
01 Ububanzi Bamandla Amandla Ebhethri
Njengamanje, ama-inverter okugcina amandla emakethe ahlukaniswe izigaba ezimbili ngokusekelwe ku-voltage yebhethri.Olunye uhlobo luklanyelwe amabhethri kagesi alinganiselwe angu-48V, anebanga le-voltage yebhethri ngokuvamile eliphakathi kuka-40-60V, okwaziwa ngokuthi ama-inverter okugcina amandla ebhethri aphansi.Olunye uhlobo ludizayinelwe amabhethri anamandla kagesi, anebanga lebhethri eliguquguqukayo, elihambisana kakhulu namabhethri angu-200V nangaphezulu.
Okutuswayo: Lapho uthenga ama-inverters okugcina amandla, abasebenzisi badinga ukunaka ngokukhethekile ububanzi be-voltage i-inverter engakwazi ukubufaka, iqinisekise ukuthi ihambisana ne-voltage yangempela yamabhethri athengiwe.
02 Ubukhulu Amandla Okufaka I-Photovoltaic
Amandla okufaka we-photovoltaic aphezulu abonisa amandla amakhulu ingxenye ye-photovoltaic ye-inverter engawamukela.Kodwa-ke, la mandla akuwona amandla amakhulu i-inverter engawaphatha.Isibonelo, ku-inverter engu-10kW, uma amandla okufaka ama-photovoltaic aphezulu angu-20kW, ukukhishwa okuphezulu kwe-AC ye-inverter kusengu-10kW kuphela.Uma i-photovoltaic array engu-20kW ixhunyiwe, ngokuvamile kuzoba nokulahlekelwa kwamandla angu-10kW.
Ukuhlaziya: Sithatha isibonelo se-inverter ye-GoodWe yokugcina amandla, ingagcina u-50% wamandla e-photovoltaic kuyilapho ikhipha u-100% AC.Nge-inverter engu-10kW, lokhu kusho ukuthi ingakwazi ukukhipha u-10kW AC kuyilapho igcina u-5kW wamandla e-photovoltaic ebhethrini.Nokho, ukuxhuma i-array engu-20kW kusazomosha u-5kW wamandla e-photovoltaic.Lapho ukhetha i-inverter, ungacabangi nje kuphela amandla okufaka we-photovoltaic aphezulu kodwa futhi namandla angempela i-inverter engakwazi ukuwaphatha kanyekanye.
03 Ikhono Lokugcwala Kwe-AC
Kuma-inverter okugcina amandla, uhlangothi lwe-AC ngokuvamile luqukethe okukhiphayo okuboshwe ngegridi kanye nokuphumayo kwe-off-grid.
Ukuhlaziya: Okukhiphayo okuboshelwe kwigridi ngokuvamile akunawo amandla okulayisha ngokweqile ngoba lapho kuxhunywe kugridi, kunosekelo lwegridi, futhi isiguquli esiguquguqukayo asidingi ukuphatha imithwalo ngokuzimela.
Ngakolunye uhlangothi, okukhiphayo ngaphandle kwegridi, ngokuvamile kudinga amandla okulayisha ngokweqile esikhathi esifushane njengoba kungekho ukusekela kwegridi ngesikhathi sokusebenza.Isibonelo, isiguquli sesitoreji samandla esingu-8kW singase sibe namandla alinganiselwe aphuma kugridi angu-8KVA, anamandla abonakalayo aphezulu angu-16KVA kufika kumasekhondi angu-10.Lesi sikhathi semizuzwana eyi-10 ngokuvamile sanele ukuphatha amandla okuhlinzwa ngesikhathi sokuqala kwemithwalo eminingi.
04 Ukuxhumana
Izixhumi zokuxhumana zama-inverter okugcina amandla ngokuvamile zihlanganisa:
4.1 Ukuxhumana namabhethri: Ukuxhumana namabhethri e-lithium ngokuvamile kuvame ukuxhumana ne-CAN, kodwa izivumelwano phakathi kwabakhiqizi abahlukene zingahluka.Uma uthenga ama-inverter namabhethri, kubalulekile ukuqinisekisa ukuhambisana ukuze ugweme izinkinga ngokuhamba kwesikhathi.
4.2 Ukuxhumana Nezinkundla Zokuqapha: Ukuxhumana phakathi kwama-inverter okugcina amandla kanye nezinkundla zokuqapha kufana nama-inverter aboshwe ngegridi futhi kungasebenzisa i-4G noma i-Wi-Fi.
4.3 Ukuxhumana Nezinhlelo Zokuphatha Amandla (EMS): Ukuxhumana phakathi kwezinhlelo zokugcina amandla kanye ne-EMS ngokuvamile isebenzisa i-RS485 enezintambo enokuxhumana okujwayelekile kwe-Modbus.Kungase kube nomehluko kumaphrothokholi e-Modbus phakathi kwabakhiqizi be-inverter, ngakho-ke uma ukuhambisana ne-EMS kuyadingeka, kuyatuseka ukuthi uxhumane nomkhiqizi ukuze uthole ithebula lephuzu lephrothokholi ye-Modbus ngaphambi kokukhetha isiguquli.
Isifinyezo
Imingcele ye-inverter yokugcina amandla iyinkimbinkimbi, futhi ingqondo ngemuva kwepharamitha ngayinye ithonya kakhulu ukusetshenziswa okungokoqobo kwama-inverters okugcina amandla.
