Yiya kumxholo 
I-BESS eyi-300kW / 1MWh inika iiyure ezi-3.33 kumandla apheleleyo achaziweyo phambi kokuba kubekho imida ye-SOC, ilahleko yoguqulo, ukuncitshiswa kwamandla ngenxa yobushushu kunye nokuguga kwebhetri. Ngenxa yoko, iprojekthi yaseNigeria eyi-C&I idinga ubalo lwamandla asetyenziswayo phambi kokuba i-EPC imisele inani lezixhobo.
Phambi kokucela iikowuti, chaza i-voltage ye-PCC, isilinganiso se-transformer, iprofayili yemithwalo, iindawo zokudibanisa ijenereyitha ne-PV, umthetho wokuthumela ngaphandle, ugcino lwasesilahlweni kunye noxanduva lwe-EPC yasekuhlaleni. Ezi ngeniso zivumela ababoneleli ukuba banike iikowuti zomsebenzi wombane ofanayo kunye nemida yokuhanjiswa.
Umxholo weprojekthi esetyenziselwe eli nqaku: Uphando olungaziwayo lwe-C&I EPC yaseNigeria malunga neprojekthi yokugcina amandla yangaphandle, esekwe kwi-container, edibaniswe kwi-grid, enika iinkonzo kwizixhobo zemizi-mveliso ezinkulu. Olu phando lubeke imida ye-300kW ne-1,000kWh, ngelixa ishedyuli yombane, iprofayile yemthwalo, ukuphakama kwendawo kunye nomda wokugqibela womsebenzi wasentsimini zishiywe zivulelekile ukuze ziqinisekiswe ziinjineli.
Indlela yokukhetha ubungakanani be-BESS engu-300kW / 1MWh eNigeria
Umbuzo worhwebo kukuba ingaba olu cwangciso lunokuxhasa na isiganeko sombane esifunekayo kwindawo kanye ekuyo.
- Bhala umsebenzi njengengxelo yokusebenza. Umzekelo: “Bamba ingeniso elinganisiweyo ngaphakathi kwemida yesiza ekuvunyelwene ngayo ngexesha lokunyuka kwemveliso elirekhodiweyo.”
- Yahlula imithwalo eqhubekayo, iincopho zexeshana, iziganeko zokuqalisa iimoto kunye namasebe emithwalo ebalulekileyo.
- Chaza ukuba i-BESS ingaba ilandela ingqalasizinda yombane, ixhasa ibhasi ezimeleyo, idibanise utshintsho lomthombo, okanye idibanise la maqondana ngokwahlukeneyo kwiishedyuli ezahlukeneyo.
- Faka i-voltage ye-PCC, isilinganiso setransformer, ulungelelwaniso lwefeeder, imeko yejenereyitha ekhoyo kunye neemfuno zolungelelwaniso lwe-relay.
- Chonga umnini-mthunzi: umqhubi wesiza, i-EMS yomthengi, i-EMS yomthengisi okanye umdibanisi wolawulo we-EPC.
Kwisiganeko somthwalo we-300kW, isiphumo esiqhelekileyo se-1,000kWh ÷ 300kW singawo iiyure ezi-3.33. Olo balo luyisalathiso sokuqala nje kuphela. Ixesha eliyilweyo lufuna iwindow evunyelweneyo yokutshaja, ilahleko yoguqulo, ukuncitshiswa kwamandla ngenxa yobushushu, isabelo sokuguga kwebhetri, ukusetyenziswa kwezixhobo zokuncedisa kunye nokumila komthwalo.
Idatha ejika isicelo somthamo sibe sisiseko sobunjineli.
I-EPC ingaqokelela ezi zinto zilandelayo phambi kokuba umenzi alungiselele isiphakamiso esilawulwayo.
