Yayin da tsarin ajiyar makamashin hasken rana ke ƙara samun farin jini, yawancin mutane sun saba da ma'auni na gama gari na inverters na ajiyar makamashi. Koyaya, har yanzu akwai wasu sigogi da suka cancanci fahimta cikin zurfi. A yau, na zaɓi sigogi huɗu waɗanda galibi ana yin watsi da su yayin zabar inverter na ajiyar makamashi amma suna da mahimmanci don yin zaɓin samfurin da ya dace. Ina fatan cewa bayan karanta wannan labarin, kowa zai iya yin zabi mafi dacewa yayin fuskantar nau'ikan kayan ajiyar makamashi.
01 Wutar Wutar Batir
A halin yanzu, inverters na ajiyar makamashi a kasuwa sun kasu kashi biyu bisa ƙarfin baturi. Nau'i ɗaya an ƙirƙira shi don batir masu ƙarfin lantarki 48V, tare da kewayon ƙarfin baturi gabaɗaya tsakanin 40-60V, wanda aka sani da masu jujjuya wutar lantarki mai ƙarancin wuta. Wani nau'in an ƙera shi ne don batura masu ƙarfin lantarki, tare da kewayon ƙarfin baturi mai canzawa, galibi masu dacewa da batura na 200V da sama.
Shawarwari: Lokacin siyan inverter na ajiyar makamashi, masu amfani suna buƙatar kulawa ta musamman ga kewayon ƙarfin lantarki da inverter zai iya ɗauka, tabbatar da cewa ya yi daidai da ainihin ƙarfin lantarki na batura da aka saya.
02 Matsakaicin Ƙarfin shigarwar Hotovoltaic
Matsakaicin ƙarfin shigarwar hotovoltaic yana nuna matsakaicin ƙarfin ɓangaren hoto na inverter zai iya karɓa. Duk da haka, wannan ƙarfin ba lallai ba ne iyakar ƙarfin da inverter zai iya ɗauka. Misali, don inverter 10kW, idan matsakaicin ƙarfin shigarwar hotovoltaic shine 20kW, matsakaicin fitowar AC na inverter har yanzu 10kW ne kawai. Idan an haɗa tsararriyar hoto na 20kW, yawanci za a sami asarar wutar lantarki na 10kW.
Analysis: Ɗaukar misali na GoodWe makamashi inverter, zai iya adana 50% na photovoltaic makamashi yayin fitar da 100% AC. Don inverter 10kW, wannan yana nufin zai iya fitar da 10kW AC yayin adana 5kW na makamashin hoto a cikin baturi. Koyaya, haɗa tsararrun 20kW har yanzu zai ɓata 5kW na makamashin photovoltaic. Lokacin zabar inverter, la'akari ba kawai matsakaicin ikon shigar da hotovoltaic ba har ma da ainihin ikon da mai inverter zai iya ɗauka a lokaci guda.
03 AC Ƙarfin Ƙarfafawa
Don masu jujjuyawar ajiyar makamashi, gefen AC gabaɗaya ya ƙunshi fitarwa mai ɗaure da grid da fitar da waje.
Nazari: Abubuwan da aka ɗaure da grid yawanci ba shi da damar yin nauyi saboda idan an haɗa shi da grid, akwai goyan bayan grid, kuma mai inverter baya buƙatar ɗaukar lodi da kansa.
Fitowar Off-grid, a gefe guda, galibi yana buƙatar ikon yin awo na ɗan gajeren lokaci tunda babu tallafin grid yayin aiki. Misali, mai jujjuyawar ajiyar makamashi na 8kW na iya samun madaidaicin ƙarfin fitarwa na 8KVA, tare da mafi girman fitowar wutar lantarki na 16KVA har zuwa daƙiƙa 10. Wannan lokacin na daƙiƙa 10 yawanci ya isa don ɗaukar ƙarfin halin yanzu yayin fara yawancin lodi.
04 Sadarwa
Hanyoyin sadarwa na inverters na ajiyar makamashi gabaɗaya sun haɗa da:
4.1 Sadarwa tare da Batura: Sadarwa tare da baturan lithium yawanci ta hanyar sadarwar CAN ne, amma ladabi tsakanin masana'antun daban-daban na iya bambanta. Lokacin siyan inverters da batura, yana da mahimmanci don tabbatar da dacewa don guje wa al'amura daga baya.
4.2 Sadarwa tare da Platform na Sa ido: Sadarwa tsakanin masu canza wutar lantarki da dandamali na saka idanu yana kama da na'ura mai haɗawa da grid kuma yana iya amfani da 4G ko Wi-Fi.
4.3 Sadarwa tare da Tsarin Gudanar da Makamashi (EMS): Sadarwa tsakanin tsarin ajiyar makamashi da EMS yawanci yana amfani da waya RS485 tare da daidaitaccen sadarwar Modbus. Za a iya samun bambance-bambance a cikin ka'idojin Modbus tsakanin masana'antun inverter, don haka idan ana buƙatar dacewa da EMS, yana da kyau a yi sadarwa tare da masana'anta don samun tebirin yarjejeniya na Modbus kafin zaɓin inverter.
