Iibhetri zelanga zasekhayaibe ngumgangatho weenkqubo zamandla e-PV, kwaye ukuba inkqubo yakho yokugcina ekhethiweyo ngokucokisekileyo ayisebenzi ngokufanelekileyo kwaye ayifanelekanga kwiimpawu zenkqubo ye-PV, ngoko ke iba lutyalo-mali olubi, olungenanzuzo kwaye ulahlekelwa yimali eninzi.Uninzi lwabantu, faka iibhetri ze-lithium zamandla elanga ngenjongo yodwa yokuvelisa ukonga kunye nenkqubo ye-PV, kodwa ihlala ingasetyenziswanga ngokufanelekileyo ngokuchanekileyo kuba abanye abavelisi okanye iibrendi zebhetri zibonisa iimveliso ezineempawu ezingafanelekanga.Kodwa zeziphi iimpawu ekufuneka ibhetri yelanga yasekhaya kufuneka isebenze ngokufanelekileyo? Yintoni omele ugxininise kuyo xa ukhetha inkqubo yokugcina ukuphepha ukuchitha imali? Makhe sifumanise kunye kweli nqaku.Umthamo webhetri yeSolar yasekhayaNgenkcazo, umsebenzi webhethri ye-lithium yamandla elanga kukugcina amandla angaphezulu akhiqizwa yinkqubo ye-photovoltaic emini ukuze isetyenziswe ngokukhawuleza ukuba inkqubo ayikwazi ukuvelisa amandla okwaneleyo ukunika amandla umthwalo wekhaya.Umbane wasimahla oveliswa yile nkqubo yebhetri yelanga yasekhaya udlula endlwini, unika amandla izixhobo ezifana neefriji, oomatshini bokuhlamba kunye neempompo zobushushu, emva koko ufakwe kwigridi.Ibhetri yelanga yasekhaya yenza kube nokwenzeka ukubuyisela la mandla agqithisileyo, ebeya kuthi ngenye indlela aphantse anikwe urhulumente, kwaye ayisebenzise ebusuku, ukuthintela isidingo sokutsala amandla ongezelelweyo ngomrhumo.Kumakhaya apho igesi yendalo ingasebenziyo, yonke into ifuna ukusebenza ngombane, ngoko ke iibhetri zelanga zasekhaya zibalulekile.Unyino kuphela ukuba ubungakanani benkqubo yePV.- Indawo yophahla- Uhlahlo lwabiwo-mali olukhoyo- Uhlobo lwenkqubo (isigaba esinye okanye inqanaba lesithathu)Kwiibhetri zelanga zasekhaya, ubungakanani bubalulekile.Ubukhulu besakhono sebhetri yelanga yasekhaya, sikhulu isixa esikhulu senkcitho yenkuthazo kunye nokukhulu ukonga "okwenzekayo" okwenziwa yinkqubo yePV.Ukulinganisa okufanelekileyo, ndidla ngokucebisa inkqubo ephindwe kabini kumthamo wenkqubo yePV.Ingaba unayo i-5kW yesixokelelwano selanga? Emva koko imbono kukuhamba nebhetri ye-10kWh.Inkqubo ye-10 kW? 20 kWh ibhetri.Kwaye nangokunjalo…Oku kungenxa yokuba ebusika, xa imfuno yombane iphezulu, inkqubo ye-PV ye-1 kW ivelisa malunga ne-3 kWh yamandla.Ukuba ngokwe-avareji 1/3 yale mandla ifunxwa zizixhobo zasendlini ukuze zizisebenzise, i-2/3 yondliwa kwigridi. Ngoko ke, amaxesha ama-2 ubukhulu benkqubo efunekayo yokugcina.Entwasahlobo nasehlotyeni, inkqubo ivelisa amandla amaninzi, kodwa amandla afunliweyo awakhuli ngokufanelekileyo.Umthamo linani nje, kwaye imigaqo yokumisela ubungakanani bebhetri ikhawuleza kwaye ilula, njengoko bendikubonisile. Nangona kunjalo, iiparamitha ezimbini ezilandelayo zinobugcisa ngakumbi kwaye zibaluleke ngakumbi kwabo bafuna ngokwenene ukuqonda indlela yokufumana eyona ifanelekileyo.Ukutshaja kunye nokukhupha AmandlaKuvakala kungaqhelekanga, kodwa ibhetri kufuneka ihlawulwe kwaye ikhutshwe, kwaye ukwenzela ukuba iyenze ibe ne-bottleneck, isithintelo, esingamandla alindelekileyo kwaye alawulwa yi-inverter.Ukuba inkqubo yam yondla i-5 kW kwigridi, kodwa iibhetri zihlawulisa kuphela i-2.5 kW, ndisachitha amandla kuba i-50% yamandla ayondliwa ngaphakathi kwaye ayigcinwa.Ngethuba nje iibhetri zam zelanga zasekhaya zihlawuliswa akukho ngxaki, kodwa ukuba iibhetri zam zifile kwaye inkqubo ivelisa encinci kakhulu (ebusika), amandla alahlekileyo athetha imali elahlekileyo.Ngoko ndifumana ii-imeyile ezivela kubantu abane-10 kW ye-PV, i-20 kWh yeebhetri (ngoko ubungakanani obuchanekileyo), kodwa i-inverter inokuphatha kuphela i-2.5 kW yokutshaja.Ukutshaja/ukukhupha amandla nako kwakhona kuchaphazela ixesha lokutshaja kwebhetri.Ukuba kufuneka nditshaje ibhetri eyi-20 kWh ene-2.5 kW yamandla, indithatha iiyure ezisi-8. Ukuba endaweni ye-2.5 kW, ndihlawula nge-5 kW, ithatha isiqingatha selo xesha. Ngoko uhlawula ibhetri enkulu, kodwa usenokungakwazi ukuyibiza, kungekhona ngenxa yokuba inkqubo ayivelisi ngokwaneleyo, kodwa ngenxa yokuba i-inverter icotha kakhulu.Oku kwenzeka rhoqo ngeemveliso "ezidibeneyo", ngoko ke ndine-inverter ezinikeleyo ukufanisa imodyuli yebhetri, uqwalaselo lwalo luhlala lunandipha lo mda wesakhiwo.Ukutshaja/ukukhupha amandla ukwaluphawu oluphambili lokuxhaphaza ngokupheleleyo ibhetri ngexesha leemfuno eziphezulu.Kubusika, i-8pm, kwaye indlu iyavuya: iphaneli yokungenisa iyasebenza kwi-2 kW, impompo yokufudumala ityhala i-heater ukutsala enye i-2 kW, ifriji, iTV, izibane kunye nezixhobo ezahlukeneyo zisathatha i-1 kW kuwe, kwaye ngubani owaziyo, mhlawumbi unemoto yombane etshajayo, kodwa masiyikhuphe kwi-equation okwangoku.Ngokucacileyo, phantsi kwezi meko, amandla e-photovoltaic awaveliswanga, uneebhetri zokutshaja, kodwa awunyanzelekanga ukuba "uzimele okwethutyana" ngokuchanekileyo kuba ukuba indlu yakho idinga i-5 kW kwaye iibhetri zibonelela kuphela nge-2.5 kW, oku kuthetha ukuba i-50% yamandla. usathatha kwigridi kwaye uyayihlawula.Uyawubona lo mnqa?Umvelisi ucebisa i-solar yasekhaya engafanelekanga kuwe, kodwa uyayithenga nangona kunjalo kuba awuqaphelanga inkalo ephambili okanye, ngakumbi, umntu okubonelele ngemveliso ukunike eyona nkqubo inexabiso eliphantsi apho anokwenza khona. imali eninzi ngaphandle kokukunika naluphi na ulwazi olufanelekileyo.Ewe, kusenokwenzeka ukuba naye akazazi ezi zinto.Ukudityaniswa nokutshaja / ukukhupha amandla kukuvula izibiyeli zengxoxo yesigaba se-3/yesigaba esinye kuba ezinye iibhetri, umzekelo, iibhetri ezi-2 ze-BSLBATT Powerwall azikwazi ukufakwa kwinkqubo yesigaba esinye kuba iziphumo zombane ezimbini zongeza. (10+10=20) ukufikelela kumandla afunekayo kwizigaba ezithathu.Ngoku, makhe siqhubele phambili kwiparameter yesithathu yokuqwalasela xa ukhetha ibhetri yelanga yasekhaya: uhlobo lweebhetri zelanga zasekhaya.Uhlobo lwebhetri yeSolar yaseKhayaQaphela ukuba le parameter yesithathu yeyona "jikelele" kwezi zintathu zinikiweyo, njengoko ibandakanya imiba emininzi ekufanele iqwalaselwe, kodwa ikwinqanaba lesibini kwiiparamitha ezimbini zokuqala ezisandula ukunikezelwa.Ulwahlulo lwethu lokuqala lweteknoloji yokugcina kwindawo yalo yokunyuka. AC-alternating okanye DC-continuous.Uphononongo oluncinci olusisiseko.- Iphaneli yebhetri ivelisa amandla eDC- Umsebenzi we-inverter yenkqubo kukuguqula amandla avela kwi-DC ukuya kwi-AC, ngokweeparamitha zegridi echaziweyo, ngoko ke inkqubo yesigaba esisodwa yi-230V, 50/60 Hz.- Le ngxoxo inokusebenza kakuhle, ngoko ke sinepesenti encinci okanye encinci yokuvuza, oko kukuthi "ilahleko" yamandla, kwimeko yethu sithatha ukusebenza kakuhle kwe-98%.-Ibhetri yelanga ye-lithium ibiza ngamandla eDC, hayi amandla e-AC.Ngaba yonke loo nto icacile? Kulungile...Ukuba ibhetri ikwicala le-DC, kwaye ngoko ke kwi-DC, i-inverter iya kuba nomsebenzi wokuguqula amandla okwenene awenziwe kwaye asetyenziswe, ukuhambisa amandla aqhubekayo enkqubo ngokuthe ngqo kwibhetri - akukho kuguqulwa.Ngakolunye uhlangothi, ukuba ibhetri ikwicala le-AC, sinamaxesha e-3 inani lokuguqulwa kwe-inverter.- I-98% yokuqala ukusuka kwiplanti ukuya kwigridi- Eyesibini ihlawulisa ukusuka kwi-AC ukuya kwi-DC, inika ukusebenza kakuhle kwe-96%.- Ukuguqulwa okwesithathu ukusuka kwi-DC ukuya kwi-AC yokukhupha, okubangelwa ukusebenza kakuhle kwe-94% (kuthatha ukusebenza kakuhle kwe-98% kwi-inverter, ngaphandle kokuqwalasela ilahleko kwinkqubo yokuhlawula kunye nokukhupha, ekhoyo kuzo zombini iimeko).Ngoku kubalulekile ukubonisa ukuba ukuhlangana kwezi teknoloji zimbini sisigqibo sokufakela iibhetri zokugcina amandla ngelixa ukwakhiwa kwenkqubo ye-PV, ekubeni iteknoloji kwicala le-AC zezona zisetyenziswayo xa kulungiswa ngokutsha, oko kukuthi ukufaka iibhetri kwinkqubo ekhoyo. , ekubeni abafuni ukuguqulwa okubalulekileyo kwinkqubo ye-PV.Enye inkalo yokuqwalasela xa kuziwa kuhlobo lwebhetri yikhemistri yokugcina.Ingaba i-LiFePo4, i-lithium ion ecocekileyo, ityuwa, njl., inkampani nganye inamalungelo awodwa omenzi, isicwangciso sayo.Yintoni esifanele siyijonge? Yiyiphi onokuyikhetha?Ilula: inkampani nganye ityala izigidi kuphando kunye namalungelo awodwa omenzi wechiza ngenjongo elula yokufumana eyona bhalansi ingcono phakathi kweendleko, ukusebenza kakuhle kunye nesiqinisekiso. Xa kuziwa kwiibhetri, le ngenye yezona zinto zibalulekileyo: isiqinisekiso sokuqina kunye nokusebenza komthamo wokugcina.Isiqinisekiso ke ngoko siba yiparameter engalindelekanga "yeteknoloji" esetyenzisiweyo.Ibhetri yelanga yasekhaya sisixhobo, njengoko besitshilo, sisebenzela ukusebenzisa kakuhle inkqubo yePV kunye nokwenza ukonga ekhaya.Ukuba ayikho, kufuneka uphile nakanjani!Emva kokunyamezela iminyaka eyi-10, i-70% yeenzuzo zisekhona kwaye nokuba ziphuke, akufuneki ukuba uzibuyisele ngenxa yokuba kwiminyaka emi-5, eyi-10 okanye eyi-15, umhlaba unokuba yindawo eyahlukileyo ngokupheleleyo.Unokukuphepha njani ukwenza iimpazamo?Ngokulula, ngokujika ngokukhawuleza kubantu abaqeqeshiweyo, abanolwazi abaya kuhlala bebeka umthengi embindini weprojekthi, hayi ezabo umdla.Ukuba ufuna inkxaso eyongezelelweyo, ikhaya lethu le-BSLBATTumenzi webhetri yelangangokuqinisekileyo unakho ukukukhokela ekukhetheni eyona mveliso ifanelekileyo kwikhaya lakho.
