6 FAQs about [Energy storage ratio]

What is the difference between energy capacity and E/P ratio?

Energy capacity (kWh) is the total amount of energy the storage module can deliver. E/P ratio is the storage module’s energy capacity divided by its power rating (= energy capacity/power rating). The E/P ratio represents the duration (hours, minutes, or seconds) the storage module can operate while delivering its rated output.
