Khetha iNjongo yokuSebenza Phambi kokuKhetha iBhetri
Iifektri zeemoto zineenkqubo ezinempembelelo ezahluke kakhulu zokuphazanyiswa. Ukuhla okufutshane kwevoltheji kunokumisa umgca olawulwa yi-PLC nangona intlobo-ntlobo yamandla asetyenziswa yifektri iphela ingatshintshi kakhulu. Inkqubo yokubumba, yokunyanga ngobushushu, yokugquma, yomoya oxineneyo okanye yamanzi abandayo isenokufuna amandla kunye nexesha elaneleyo ukuze ifikelele kwimeko ekhuselekileyo. Ezinye iilodi zinokulinda ijenerator okanye zihlale zingadityaniswanga.
- 🛡️ Ukuvalwa okulawulwayo: Zigcineni zixhonyiwe kumandla izilawuli, iziqhuba, iimpompo, izixhobo zokukhupha nomatshini wokusebenza ezivunyiweyo, de indawo nganye yokuvelisa iqinisekise ukuba ikwimeko ekhuselekileyo.
- ⚡ Ukukhwela okufutshane: Thintela ukuphuma kwekontaktha, ukusetwa kwakhona kwe-PLC okanye ukuphazamiseka kwe-drive ngexesha leengxaki ngaphakathi kwesigcawu sokutshintshela esivunyiweyo.
- 🏭 Ukuqhubeka okukhethiweyo: Sebenzisa kuphela imigca apho iindleko zokuphepha inkunkuma okanye zokuqalisa ngokutsha zivakalisa amandla kunye nombane webhetri ofunekayo.
- ☀️ Ukusetyenziswa kwamandla elanga: Gcina okanye sebenzisa i-PV enomthamo ongaphantsi okanye exabiso eliphantsi emva kokuba imiqathango yenkqubo kunye nokudityaniswa kugutyungelwe.
- ⛽ Ukuphuculwa kwejenereyitha: Sebenzisa i-BESS ukulawula imithwalo enyathelo-nyathelo, ukulibaziseka kokuqalisa kunye neendawo zokusebenza zegenerator ezingasebenzi kakuhle, ngaphandle kokwenza izithembiso ezingaxhaswanga zokonga amafutha.
- 📉 Ulawulo oluphezulu: Ukuthunyelwa ngokusekelwe kwitarif yeyangempela kunye nesithuba esilinganisiweyo sokufuna, hayi uqikelelo jikelele lwe-Afrika esemzantsi lwe-charge yokufuna.
Bhala ezi njongo ngokulandelelana kwazo ngokwezinto eziphambili.

Imibuzo Ebuzwa Rhoqo
Isalathiso se-4 MWh BESS sixelela umthengi weemoto ntoni?
Ichonga kuphela amandla agciniweyo asisiseko. Ayichazi amandla e-PCS, amandla e-AC asetyenziswayo, ixesha lokusebenza, imithwalo yenkqubo, umthwalo wokuqalisa, ukonakala okanye umda wemitha wesivumelwano.
Ingaba izikhongozeli ezibini ze-ESSC1000B-2150 zingenza inkqubo ye-4 MWh?
Iiyunithi ezimbini ezipapashiweyo zilingana ne-2 MW kunye ne-4.3008 MWh ngokubala. Oko kukubala kokuqikelela kuphela; isakhiwo esihambelanayo, amandla asetyenziswayo, ukuphindaphindwa, ivoltheji yendawo kunye nokusebenza kwenkqubo zifuna ubunjineli beprojekthi kunye namaxwebhu asayiniweyo.
Ingaba i-BESS kufuneka ibe ne-backup yomthwalo ngamnye kwiziko lemoto?
Ngokuqhelekileyo akunjalo ngaphandle kwesizathu esicacileyo soshishino lweso sikhululo sonke. Zahlula ulawulo lokhuseleko, imithwalo yokuvala, iinkonzo zokuqalisa kwakhona, imithwalo eguquguqukayo kunye neenjini ezingabalulekanga kakhulu, ukuze isipaji sisetyenziselwe isiphumo sokuvelisa esivunyiweyo.
Amandla e-PCS akhethwa njani kwi-application yokuvala ngokukhuselekileyo?
Sebenzisa elona nani liphezulu le-kW okanye i-kVA elihlangeneyo kwimodeli yokucima elandelelanayo ngokwexesha, uze uqinisekise ukukhawuleza kwemoto, ukuhla kwe-voltage, i-power factor, i-impedance ye-transformer, ixesha lokugcwala ngokugqithisileyo kunye neemeko zokutshintshela zegenerator.
Yeyiphi idatha yenkqubo ekufuneka ifektri yeemoto iyinikeze?
Nika ii-SLD ezilawulwayo, imithwalo yamabanga, iirekhodi zokuphazamiseka kwesantya esiphezulu, idatha yemoto ne-VFD, izinto eziphambili kwi-feeder, ulandelelwano lwemeko ekhuselekileyo, izilawuli zegenerator, useto lokhuseleko kunye nemigqaliselo yomamkeli wemveliso.
I-EMS kufuneka iyalungelelanise njani i-BESS nejeneretha?
Chaza ukufunyanwa kokuphelelwa kukagesi kwinethiwekhi, ukuqinisekiswa kwezinto ezisebenza zodwa, inkxaso yemithwalo ebalulekileyo, ukuqaliswa nokufaneleka kwejenereyitha, ukutshintshela okwenziwa ngokwezigaba, igunya lokutshaja, umthwalo omncinci wejenereyitha, ukubuyiselwa kwezinto ezigciniweyo kunye neemeko zokusilela konxibelelwano.
Yintoni ekufuneka i-BESS PPA iqinisekise?
Amandla ombane afumanekayo karhulumente, amandla e-AC ahanjisiweyo, indawo yemitha, i-SOC yokuqala, unyango oluncedisayo, ukufumaneka, ukonakala, amalungelo okuthunyelwa, izinto ezingabandakanyekiyo kulondolozo, amaxesha okulungisa kunye nezisombululo zokusebenza.
Zeziphi iimvavanyo ezifanele ukuba kwi-FAT ne-SAT?
I-FAT kufuneka iqinisekise inkqubo e-odoliweyo kunye ne-intifesi ezilinganisiweyo. I-SAT kufuneka ingqine utshintsho lombane olufakelweyo, ulandelelwano lwemeko ekhuselekileyo yenkqubo, ulungelelwaniso lwejenereyitha, amandla ahanjisiweyo, ii-alam, ukuchacha kunye nobungqina obunophawu lwexesha.
Ingaba i-BESS ye-solid-state iyayisusa umngcipheko wokuphuma emkhawulweni ngenxa yobushushu?
Hayi. Uqwalaselo oluqinisekisiweyo lwe-solid-state okanye lwe-hybrid lunokuphucula iimpawu ezithile zokushisa kwinqanaba leseli, kodwa ukhuseleko lwenkqubo lusaxhomekeke kwi-BMS, i-PCS, ukupholisa, ukufumanisa, ukucinezela, ukwahlula, ufakelo kunye nezilawuli zokusebenza.
Yintoni ekufuneka ithunyelwe kwi-MegSolid ukuze ifumane ikowuteshini?
Thumela indawo yesiza, i-SLD, ivoltheji, idatha ye-transformer nokhuseleko, iifayile zomthwalo, ulandelelwano lokuvala inkqubo, uluhlu lweemoto, idatha ye-PV nejenereyitha, umda we-PPA ofunekayo, iimeko zesiza kunye neshedyuli yokuhanjiswa.
Isetyenziselwa ntoni indawo yokugcina iibhetri zemizi-mveliso eGqeberha?
Ugcino lwebhetri yezoshishino eGqeberha lunokuxhasa ukuvalwa kwenkqubo okulawulwayo, ukuqhubeka okukhethiweyo, ukusetyenziswa kwamandla elanga, ulungelelwaniso lwejenereyitha kunye nolawulo olulinganisiweyo lwamaxesha oxinzelelo kumaziko emveliso xa luyilwe ngokusekelwe kwidatha yombane nemveliso ekhethekileyo yefektri.
Ingaba iprojekthi yeemoto yaseGqeberha yoluntu yifakelo leMegSolid?
Hayi. Ikhuthazwe njengereferensi yemarike ebhalwe ngokuzimeleyo. Eli nqaku alibanga ukuba iMegSolid yahanjisela loo projekthi kwaye alidluliseli iinkcukacha zayo zoyilo ezingachazwanga kwelinye iziko.
Yeyiphi iqonga leMegSolid elinokuvavanywa kwiprojekthi yodidi lwe-4 MWh?
Hlola iindidi zomthamo ze-ESSC1000B-2150 ne-5000INTL emva kokuba amandla e-PCS, amandla anikezelweyo, ivoltheji yesiza, ukuphindaphindwa, kunye nolandelelwano lokusebenza kuchazwe. Ukukhetha kokugqibela kufuna ikowuteshini yeprojekthi, idatasheet esayiniweyo, i-BOM kunye nematrix yokuthotyelwa.
