Customer ServiceConclusion. State of Charge (SOC), Depth of Discharge (DOD), and Cycle(s) are crucial parameters that impact the performance and longevity of batteries and energy storage systems.
Customer ServicePower is the amount of electricity needed to run an appliance at a given moment. This is the instantaneous supply of electrical energy, and it is measured in kilowatts (kW). Energy is the amount of power needed to run an appliance for a period of time; or the amount of stored electrical capacity and it is measured in kilowatt hours (kWh).
Customer ServiceThe energy storage capacity of a storage system, E, is the maximum amount of energy that it can store and release. It is often measured in watt-hours (Wh).

Customer ServiceElectricity is measured in both capacity and energy—watts and watt-hours. Understanding the difference is critical to understanding how the power grid works. Capacity is the maximum output an electricity generator can physically produce, measured in megawatts (MW).
Customer ServiceIt is usually measured in watts (W). The energy storage capacity of a storage system, E, is the maximum amount of energy that it can store and release. It is often measured in watt-hours (Wh). A bathtub, for example, is a storage system for water. Its “power” would be the maximum rate at which the spigot and drain can let water flow in and out.
The power of a storage system, P, is the rate at which energy flows through it, in or out. It is usually measured in watts (W). The energy storage capacity of a storage system, E, is the maximum amount of energy that it can store and release. It is often measured in watt-hours (Wh). A bathtub, for example, is a storage system for water.
Energy storage systems are designed with both your power and your energy needs in mind. SunVault storage systems have industry-leading power capabilities and energy storage capacities. Let’s review the difference between power and energy: Power is the amount of electricity needed to run an appliance at a given moment.
A bathtub, for example, is a storage system for water. Its “power” would be the maximum rate at which the spigot and drain can let water flow in and out. Its “capacity” would be the amount of water the tub can hold. Together, the power and the capacity determine how long it will take to fill (charge) or empty (discharge) the energy storage system.
Significance: Determines the system’s ability to meet instantaneous power demands and respond quickly to fluctuations in energy usage. • Definition: Energy capacity is the total amount of energy that an energy storage system can store or deliver over time. • Units: Measured in kilowatt-hours (kWh) or megawatt-hours (MWh).
Specifically, dividing the capacity by the power tells us the duration, d, of filling or emptying: d = E/P. Thus, a system with an energy storage capacity of 1,000 Wh and power of 100 W will empty or fill in 10 hours, while a storage system with the same capacity but a power of 10,000 W will empty or fill in six minutes.
