Energy is the amount of electricity a generator produces over a specific period of time. Many generators do not operate at their full capacity all the time.

Battery capacity. It is a measure of a battery''s ability to store or deliver electrical energy and it is expressed in units of ampere hours (Ah). An ampere hour is equal to a discharge of 1 A over 1 h. For example, a battery that discharges 15 A to a load in 10 h is described as having delivered 150 Ah.
Rated Energy Storage. Rated Energy Storage Capacity is the total amount of stored energy in kilowatt-hours (KWh) or megawatt-hours (MWh). Capacity expressed in ampere-hours (100Ah@12V for example). Storage Duration. The amount of time storage can discharge at its power capacity before exhausting its battery energy storage capacity.
The math is simple: Energy (Watt-hours) = Capacity (amp-hours) x Voltage (volts) Let''s look at an example using the equation above — if a battery has a capacity of 3 amp-hours and an average voltage of 3.7 volts, the total energy stored in that battery is 11.1 watt-hours — 3 amp-hours (capacity) x 3.7 volts (voltage) = 11.1 watt
