Ingaba iqonga leMegSolid ESSA lingasebenzisa iiseli zebhetri ze-solid-state?
Ewe. Iqonga le-ESSA elingaphandle le-C&I linokulungiselelwa ngeeseli ze-solid-state ukuze kuhlangatyezwane neemfuno ezithile zeprojekthi. Ikhowuteshini, idatasheet esayiniweyo kunye ne-BOM kufuneka zichaze ulungiselelo olunikeziweyo; olu khetho aluthethi ukuba zonke iiyunithi ze-ESSA ze-solid-state.
Yeyiphi iqela elifanele ukumisela umthwalo omncinci wejenereyitha kunye nesethingi yamandla abuyayo?
Amaxabiso kufuneka avele kumvelisi wejenereyitha, kuphando lokhuseleko kunye kunjineli weprojekthi otyunjweyo. I-MegSolid inokufaka imida eqinisekisiweyo kwingxelo yolawulo lwe-BESS ne-EMS kodwa akufuneki yenze ngokwayo izicwangciso zokhuseleko lwendawo.
Yintoni ekufuneka ingqwalaselwe ngexesha le-FAT ne-SAT?
Ubungqina bokumepisha imilinganiselo, impendulo yomyalelo, iimvume ezinxulumene nejeneretha, iimeko ezivaliweyo, ukusilela konxibelelwano, ukuhanjiswa kwe-alam, ukutshixwa kweebrakeha kunye neemeko ezivunyelweneyo zotshintsho lomthwalo. Rekhoda imiyalelo, impendulo elinganisiweyo kunye nezitampu zexesha ngokwezinto ezifunekayo zokudlula ezivunyiweyo.
Yintoni ulungelelwaniso lwe-BESS nesijenereyitha sedizili?
Yiyoyena yilo yokulawula nokukhusela enyabela i-voltage, i-frequency kunye namandla asebenzayo phakathi kwegridi, ijeneretha yedizili kunye ne-BESS kuyo yonke imo yokusebenza, kuquka iimeko zotshintsho kunye nokusilela konxibelelwano.
Ingaba i-BESS ingakuthintela konke ukucima okubangelwa kukuhamba kombane okuchaseneyo kwi-diesel-generator?
Akukho mthengisi onoxanduva onofanele aqinisekise loo nto ngaphandle kwedatha yeprojekthi kunye nophononongo lokhuseleko. I-BESS eyilwe ngokufanelekileyo inokuxhasa injongo yokusebenza, kodwa uthintelo luxhomekeke kwimilinganiselo, igunya lolawulo, imida yejenereyitha, useto lokhuseleko, uqhagamshelo lwezixhobo zombane kwindawo, ukuqaliswa kokusebenza kunye nolondolozo.
Yeyiphi eyona ndlela ikhawulezayo yokufumana ikowuteshini esele ilungele ukwamkelwa?
Thumela iphakheji enye equlethe i-SLD, idatha yemithwalo yamabanga, i-datasheet nemida yejenereyitha, iinkcukacha zemitha ye-PCC, iindlela zokusebenza ezifunekayo, amandla nexesha lokuhlala kwe-BESS, iimeko zendawo, umda wokuhanjiswa kunye nokulindelweyo kwe-FAT/SAT. Oku kuvumela ababizi ukuba babeke amaxabiso ngaphantsi kwemida yobuchwepheshe efanayo.
