FAQ
Hamas bateri pawa mi nidim tru long 'peak seving'?
Mekim 'discharge kW' bilong bateri i go antap long 'recurring peak' bilong yu antap long 'target ceiling' bilong yu, na metim 'kWh' bilong en wantaim longpela taim bilong dispela 'peak' wantaim 15% i go inap 20% risev. Pawa reiting i bikpela samting moa long kapasiti.
Wanem taim sola-tasol 'peak shaving' i no wok gut?
Em i save feil taim ol 'peaks' i kamap bihain long san i go daun, long taim bilong ol klaut, o long sotpela pairap hariap moa long PV inap long bekim. Em i save feil tu taim PV sais i liklik tumas long 'spike', o taim ol data bilong 'interval' i no soim olsem 'solar production' na 'site peaks' i wok bung wantaim.
Peak shaving i gutpela sapos pe bilong mi i no gat 'demand charge'?
Nogat long askim-sasim ekonomiks tasol. Tasol stoa i ken bekim yet long taim-bilong-yusim arbitraj, sola self-konsumsen, na bek-ap veliu. Planti ol yutiliti i wok long putim ol 'demand charges' long ol 'C&I tarifs', olsem na askim i save stap olsem "wanem taim," na i no "sapos."
Wanem sais bilong bateri i save stap long wanpela C&I peak seving projek?
Planti liklik-i go long-namel komesel projek i save kisim namel long 100 kW / 200 kWh na 500 kW / 1 MWh. Ol indastrial sait we i gat bikpela proses lod i ken nidim 1 i go inap 5 MWh. Stretpela sais i kam long ol data bilong 'interval', i no long ol 'rules of thumb'.
Olsem wanem 'peak shaving' i narakain long 'load shifting'?
Peak shaving i save daunim bikpela kW yu pulim long grid na i save makim ol 'demand charges'. Lod shifting i save muvim kWh konsumsen namel long ol taim na i makim taim-bilong-yusim eneji reit. Wanpela sistem we ol i wokim gut i save mekim tupela samting wantaim.
