U-2022 waziwa kabanzi njengonyaka wemboni yokugcina amandla, futhi ithrekhi yendawo yokugcina amandla yaziwa nangokuthi ithrekhi yegolide yimboni. Amandla aqhuba ukukhula ngokushesha kwendawo yokugcina amandla avela ekhonweni laso lokuthuthukisa ukusebenza kahle kokusetshenziswa kukagesi okuzenzakalelayo nokunciphisa izindleko zomnotho. Ngaphansi kwenkinga yamandla kanye nokuxhaswa kwenqubomgomo, umnotho ophezulu wesitoreji se-PV sokuhlala waqashelwa yimakethe, futhi isidingo sesitoreji se-PV saqala ukuqhuma. Ngesikhathi esifanayo, uma kwenzeka ukuphela kukagesi kugridi yamandla, amabhethri e-photovoltaic angahlinzeka nokuhlinzekwa kwamandla okuphuthumayo ukuze kugcinwe isidingo esiyisisekelo sikagesi sasekhaya.
Ukubhekana nenqwaba yemikhiqizo yokugcina amandla emakethe, indlela yokukhetha sekuyindaba edidayo. Ukukhetha ngokunganaki kungaholela ekuxazululeni okunganele kwezidingo zangempela, izindleko ezikhuphukayo, ngisho nezingozi ezingase zibe yingozi zokuphepha ezifaka ukuphepha komphakathi engozini. Ungazikhethela kanjani isistimu yesitoreji sasekhaya efanelekile?
Q1: Luyini uhlelo lokuhlala lwe-PV lokugcina amandla?
Uhlelo lokuhlala lwe-PV lokugcina amandla lusebenzisa idivayisi yokuphehla amandla elanga ophahleni ukuze lunikeze ugesi ophehlwa emini ezintweni zikagesi ezihlala endlini, futhi lugcina ugesi oweqile ohlelweni lokugcina amandla e-PV ukuze lusetshenziswe ngesikhathi samahora aphakeme.
Izingxenye ezibalulekile
Umnyombo wesistimu yokuhlala ye-PV yokugcina amandla uqukethe i-photovoltaic, ibhethri kanye ne-hybrid inverter. Inhlanganisela yendawo yokugcina amandla ye-PV kanye ne-photovoltaic yokuhlala yakha uhlelo lokuhlala lwe-PV lokugcina amandla, oluhlanganisa ikakhulukazi izingxenye eziningi ezifana namabhethri, i-inverter ye-hybrid kanye nesistimu yezingxenye, njll.
Q2: Yiziphi izingxenye zezinhlelo zokuhlala ze-PV zokugcina amandla?
Izixazululo zesistimu ye-RENAC Power yokugcina amandla okuhlala eyodwa/izigaba ezintathu zihlanganisa ukukhethwa kwebanga lamandla ukusuka ku-3-10kW, ezinikeza amakhasimende ukukhetha okwengeziwe futhi zihlangabezana ngokugcwele nezidingo ezihlukahlukene zikagesi.
Ama-inverters okugcina amandla e-PV amboza imikhiqizo eyodwa/isigaba sesithathu, imikhiqizo yamandla kagesi aphezulu/aphansi: I-N1 HV, i-N3 HV, nochungechunge lwe-N1 HL.
Isistimu yebhethri ingahlukaniswa ngamabhethri aphezulu-voltage kanye ne-low-voltage ngokuya nge-voltage: i-Turbo H1, i-Turbo H3, nochungechunge lwe-Turbo L1.
Ngaphezu kwalokho, Amandla e-RENAC nawo anohlelo oluhlanganisa ama-inverter ayi-hybrid, amabhethri e-lithium, nezilawuli: uchungechunge lwe-All-IN-ONE lwemishini ehlanganisiwe yokugcina amandla.
I-Q3: Ungangikhethela kanjani umkhiqizo ofanele wokugcina indawo yokuhlala?
Isinyathelo 1: Isigaba esisodwa noma isigaba sesithathu? I-voltage ephezulu noma i-voltage ephansi?
Okokuqala, kuyadingeka ukuqonda ukuthi imitha kagesi yendawo yokuhlala ihambisana nogesi wesigaba esisodwa noma ezintathu. Uma imitha ibonisa Isigaba esingu-1, imele ugesi wesigaba esisodwa, futhi inverter ye-hybrid yesigaba esisodwa ingakhethwa; Uma imitha ibonisa iSigaba sesi-3, imele ugesi wezigaba ezintathu, futhi ama-inverters e-hybrid ezigaba ezintathu noma isigaba esisodwa angakhethwa.
Uma kuqhathaniswa nezinhlelo zokuhlala zamandla kagesi aphansi, isistimu ye-REANC yokugcina amandla kagesi aphezulu inezinzuzo eziningi!
Mayelana nokusebenza:usebenzisa amabhethri omthamo ofanayo, ibhethri yamanje yesistimu yokugcina i-optical high-voltage incane, ibangela ukuphazamiseka okuncane ohlelweni, futhi ukusebenza kahle kwesistimu yokugcina ukukhanya kwe-voltage ephezulu kuphezulu;
Mayelana nokuklama kwesistimu, i-topology yesifunda ye-high-voltage hybrid inverter ilula, incane ngosayizi, ilula ngesisindo, futhi ithembekile kakhulu.
Isinyathelo sesi-2: Ingabe umthamo mkhulu noma uncane?
Usayizi wamandla we-hybrid inverters ngokuvamile unqunywa amandla amamojula we-PV, kuyilapho ukukhethwa kwamabhethri kukhethwa kakhulu.
Kumodi yokuzisebenzisela wena, ngaphansi kwezimo ezijwayelekile, amandla ebhethri namandla okushintshashintsha alinganiswa ngesilinganiso esingu-2:1, esingaqinisekisa ukusebenza komthwalo futhi sigcine amandla amaningi ebhethri ukuze asetshenziswe ezimweni eziphuthumayo.
Ibhethri lephakethe elilodwa le-RENAC Turbo H1 linamandla angu-3.74kWh futhi lifakwe ngendlela estakiwe. Ivolumu yephekhi elilodwa nesisindo kuncane, kulula ukuthwala, ukuyifaka, kanye nokunakekelwa. Isekela amamojula amabhethri angu-5 ochungechungeni, anganweba umthamo webhethri ufike ku-18.7kWh.
Uchungechunge lwe-Turbo H3 amabhethri e-lithium aphezulu anomthamo webhethri owodwa ongu-7.1kWh/9.5kWh. Ukwamukela indlela yokufaka efakwe odongeni noma ephansi, ekwazi ukukala okuguquguqukayo, esekela amayunithi angafika kwangu-6 ngokuhambisana, kanye nomthamo onganwetshwa ube ngu-56.4kWh. Idizayini yokuxhuma nokudlala, enokwabiwa okuzenzakalelayo kwama-ID afanayo, kulula ukuyisebenzisa nokunwetshwa futhi kungonga isikhathi esiningi sokufaka nezindleko zomsebenzi.
Uchungechunge lwe-Turbo H3 amabhethri e-lithium aphezulu-voltage asebenzisa amaseli e-CATL LiFePO4, anezinzuzo ezibalulekile ekuhambisaneni, ukuphepha, nokusebenza okuphansi kwezinga lokushisa, okuwenza abe yinketho ekhethwayo kumakhasimende ezindaweni zokushisa eziphansi.
Step 3: Kuhle noma kuyasebenziseka?
Uma kuqhathaniswa nohlobo oluhlukile lwesistimu yokugcina amandla ye-PV, umshini ALL-IN-ONE ujabulisa kakhulu ukuphila. I-All in one series yamukela idizayini yesitayela yesimanje kanye nencane, ihlanganisa endaweni yasekhaya futhi ichaze kabusha ubuhle bamandla ahlanzekile ekhaya enkathini entsha! Idizayini ehlanganisiwe ehlakaniphile yenza kube lula ukufaka nokusebenza, ngepulaki nedizayini yokudlala ehlanganisa ubuhle nokusebenza.
Ngaphezu kwalokho, uhlelo lwe-RENAC lokugcina indawo yokuhlala lusekela izindlela zokusebenza eziningi, okuhlanganisa imodi yokuzisebenzisela wena, imodi yesikhathi sokuphoqelela, imodi yokusekelayo, imodi ye-EPS, njll., ukuze kuzuzwe ukuhlela okuhlakaniphile kwamandla ezindlini, ukulinganisela ingxenye yokuzisebenzisa kwabasebenzisi kanye nogesi oyisipele. , kanye nokunciphisa izikweletu zikagesi. Imodi yokuzisebenzisela wena kanye nemodi ye-EPS yizona ezisetshenziswa kakhulu eYurophu. Ingase futhi isekele izimo zohlelo lokusebenza lwe-VPP/FFR, ikhuphule inani lamandla elanga lasekhaya namabhethri, kanye nokufeza ukuxhumana kwamandla. Ngesikhathi esifanayo, isekela ukuthuthukiswa nokulawula okukude, ngokuchofoza okukodwa kwemodi yokusebenza, futhi ingalawula ukugeleza kwamandla nganoma yisiphi isikhathi.
Lapho bekhetha, abasebenzisi bayelulekwa ukuthi bakhethe umkhiqizi ochwepheshile onezixazululo zesistimu yokugcina amandla ye-PV kanye namandla okukhiqiza emikhiqizo yokugcina amandla. Ama-inverter ama-Hybrid namabhethri ngaphansi komkhiqizo ofanayo angenza kangcono ngokuphumelelayo futhi axazulule inkinga yokufanisa uhlelo nokuvumelana. Bangakwazi futhi ukuphendula ngokushesha ngemva kokuthengisa futhi baxazulule ngokushesha izinkinga ezingokoqobo. Uma kuqhathaniswa nokuthenga ama-inverters namabhethri avela kubakhiqizi abahlukene, umphumela wangempela wohlelo lokusebenza uvelele kakhulu! Ngakho-ke, ngaphambi kokufakwa, kuyadingeka ukuthola ithimba lochwepheshe lokuklama izixazululo zokuhlala ezihlosiwe zokugcina amandla e-PV.
Njengomhlinzeki ohamba phambili womhlaba wonke wezixazululo zamandla avuselelekayo, i-RENAC Power igxile ekuhlinzekeni amandla asabalalisiwe athuthukile, amasistimu okugcina amandla, nezixazululo zokuphatha amandla ngobuhlakani ebhizinisini lokuhlala nelezentengiso. Ngesipiliyoni sembonini esingaphezu kweminyaka eyishumi, ukuqamba izinto ezintsha namandla, iRENAC Power isiwuphawu olukhethwayo lwezinhlelo zokugcina amandla ezindlini eziningi kakhulu.
