6 FAQs about [Energy storage rated power unit]
What is rated energy storage capacity?
Rated Energy Storage Capacity is the total amount of stored energy in kilowatt-hours (KWh) or megawatt-hours (MWh). It can also be expressed in ampere-hours (e.g., 100Ah@12V). This capacity determines the amount of time storage can discharge at its power capacity before exhausting its battery energy storage capacity.
What is the difference between rated power capacity and storage duration?
Rated power capacity is the total possible instantaneous discharge capability of a battery energy storage system (BESS), or the maximum rate of discharge it can achieve starting from a fully charged state. Storage duration, on the other hand, is the amount of time the BESS can discharge at its power capacity before depleting its energy capacity.
