Imalunga nje ne-5.4% yesidingo esibaliweyo, ngoko ke akufanelanga iphathwe njengomlinganiselo ongakumbi wokulungiselela iimeko ezingalindelekanga. Uvavanyo lwexesha eliphakathi kunye nokuqinisekiswa kwesivumelwano malunga namandla asetyenziswayo kusafuneka.
Kutheni ijenereyitha itshintshwe yaba yi-66 kW iiyure ezine kumzekelo?
Ishedyuli elungisiweyo kufuneka ibuyise ukusetyenziswa kwebhetri kwemihla ngemihla kunye ne-5.0 kWh yamandla oncedo. Ijenereyitha eyi-30 kW ehambelana ngqo nomthwalo we-30 kW ayinakukwazi ukutshaja kwakhona ibhetri.
Ingaba ijeneretha ingahlala icinyiwe ukusukela ngo-22:00 ukuya ku-08:00?
Kuphela xa i-BESS inamandla aneleyo asebenzisekayo, i-kVA, i-SOC yomgcino kunye nobuchule bokuziqalisa, kwaye ihotele inesicwangciso esicacisiweyo sokunqunyulwa kombane kwiimeko ezingaqhelekanga.
Kwenzeka ntoni xa ibhetri ifikelele kwi-SOC ephezulu?
I-EMS kufuneka inciphise i-PV, inciphise ukutshaja kwejenereyitha okanye itshintshe imo yokusebenza ngokwe-sequence evunyiweyo. Ukhuselo oluxhunyiweyo ngokwasemgangathweni kufuneka luhlale lukhona ukuba unxibelelwano luyasilela.
Ingaba i-IP54 ingqina ukumelana nokutshiza kweyunivesi?
Hayi. I-IP54 ichaza ukukhuselwa ekungeneni, hayi ukumelana nokugqwala elwandle. Iprojekthi kufuneka icacise ngokwahlukeneyo isigqubuthelo, imathiriyeli, ubungqina bokutshiza ngetyuwa, iindawo zokungena kweekhebula kunye nokhuseleko lwe-heat-exchanger.
Ingaba i-MEGA PCS ezahlukileyo ingafakwa ngaphandle ecaleni kwehotele?
Iphepha le-PCS elipapashiweyo lidwelisa i-IP21. Ngenxa yoko, ifuna igumbi lombane elikhuselweyo okanye isingxobo esikhusela kwimozulu esivunyiweyo yifektri kwiprojekthi eyodwa.
Ingaba i-EXW iquka iindleko zothutho lwamazwe ngamazwe kunye nokuhanjiswa kwisiqithi?
Ngokwesiqhelo hayi. Phantsi kwe-EXW, umthengi ngokubanzi ulungiselela ukulayishwa, iinkqubo zokuthumela iimpahla kumazwe angaphandle kunye nokuthuthwa ukusuka kwindawo ekhankanyiweyo, ngaphandle kokuba isivumelwano sokuthengisa sitshintsha ezo njongo.
Ingaba i-EXW ichaza i-FAT, i-SAT kunye nenkxaso yokuqalisa ukusebenza?
Hayi. Ii-Incoterms zabelana ngemisebenzi yokuhambisa, iindleko kunye nomngcipheko wothutho. I-FAT, i-SAT, ukuqaliswa kokusebenza, isoftware kunye nenkxaso yewaranti kufuneka zibhalwe ngokwahlukileyo kwikowuteshini nakwikhontrakthi.
Yintoni ekufuneka i-EPC yaseThailand iqinisekise phambi kokuba ivume i-microgrid yesiqithi?
Qinisekisa iimfuno zombane nezokwakha zaseThai ezisebenzayo, iimvume zegunya lendawo, ukubethezwa komhlaba, ukhuseleko, udibaniso lwejenereyitha, ukungqinelana kwe-PV-inverter, ufikelelo lomlilo, ukuchanabeka elwandle kunye novavanyo lokwamkelwa kwendawo kanye.
Isicwangciso sokuhanjiswa kwesiqithi saseThailand sifanele sakhiwe njani?
Qinisekisa i-Incoterm nendawo echaziweyo, indlela yomthumeli-ophawulweyo, amaxwebhu ezinto eziyingozi, i-inshorensi yolwandle, ukuphathwa kwizibuko lokufikela, imida yenqanawa yaseziqithini, iindawo zokuphakamisa, ixesha elivumelekileyo ngokwemozulu kunye nogcino olukhuselekileyo phambi kokuba kuqaliswe umbane.
Yeyiphi inkcazelo ekufuneka ihotele esesiqithini iyithumele ukuze ifumane ikowuteshini yeMegSolid?
Thumela idatha yemithwalo yexesha elithile, umzobo womgca omnye, ubungakanani be-PV kunye nemodeli ye-inverter, iphepha ledatha legenerator kunye nekhava yamafutha, umgaqo-nkqubo weeyure zokuthula, ubushushu bendawo kunye nokuchanabeka kweyunivesithi, isipaji esifunekayo, imiqobo yezothutho kunye nematrix yoxanduva ye-EXW okanye ye-FCA eceliweyo.
