A: Wanpela 'demand charge' em i wanpela pe we i kamap long pawa bilong pawa we wanpela 'facility' i kisim bihainim ol lo we i stap insait long 'tariff' bilong en. Ol i save kolim long dola long wanwan kilowat na i no long dola long wanwan kilowat-aua.
Q: Stoa bilong Bateri inap long daunim ol 'Demand Charges'?
A: Ating. Wanpela bateri inap long 'discharge' taim 'facility load' i bikpela na daunim pawa we i kam long 'utility meter'. Ol sevings i dipen long pe, taim bilong salim, taim bilong 'peak', pawa na eneji bilong bateri, na sapos taim ol i makim i makim 'billed demand'.
Q: Eneji Stoa i Daunim Total Elektrisiti Konsumsen?
A: Nogat tru. Storage i save senisim eneji long taim na senisim 'grid load profile'. Bikos ol ril sistem i gat ol lus, long daunim olgeta kWh i save nidim gutpela wok o wok gut na i no long putim ol samting tasol.
Q: Hamas Yutiliti Data Mi Mas Lukluk?
A: Wanpela ful yia bilong ol bil na ol data bilong ol intaval em i gutpela stating poin winim wanpela mun tasol. Ol fasiliti we i gat strongpela senis long sisen o senis long operesen sediul i ken nidim moa wok painimaut.
Q: Hau bai mi save wanem sais bilong bateri mi nidim?
A: Stat wantaim 'load profile' na 'tariff'. KW we ol i nidim i dipen long hamas 'peak power' ol i mas rausim. KWh we ol i nidim i dipen long hamas taim ol i mas saplaim dispela pawa, na tu, gutpela wok bilong en, mak bilong sasim, mak bilong wok, bagarap, na ol narapela yus keis.
Q: ?Behind-The-Meter Storage I Yusful Wantaim Sola Tasol?
