The capacity of a battery is typically measured in megawatt-hours (MWh) or kilowatt-hours (kWh), and it represents the total amount of energy that can be stored in the battery. The duration of a battery, on the other hand, is the length of time that a battery can be discharged at its power rating. This can be calculated by dividing the energy
Thus, we can take up to 150% of the ac power rating from our ESS to size the PV array. The Enphase Encharge has an ac power rating of 1.28 kWac per unit. Multiplying by 1.5, we find that we will need no more than 1.92 kVA (ac) of PV per Encharge unit. Finally, we use our PV array ac rating to calculate the number of IQ inverters for the
Calculate the capacity of the BESS: To calculate the capacity of the BESS, simply multiply the rated energy of the battery by the DOD: Capacity (kWh) = Rated Energy (kWh) * Depth of Discharge (%) For example, if the battery has a rated energy of 100 kWh and a DOD of 80%: Capacity (kWh) = 100 kWh * 0.80 = 80 kWh.
