About Photovoltaic Energy StorageA motor capacitor is a device that stores and releases electrical energy in a circuit. It''s essential for starting and running electric motors by providing the necessary reactive power. The size of the capacitor determines the amount of energy it can store, making the accurate calculation of the size paramount to motor functionality.
About Photovoltaic Energy StorageThe capacitance of a capacitor is a bit like the size of a bucket: the bigger the bucket, the more water it can store; the bigger the capacitance, the more electricity a capacitor can store. There are three ways to increase the capacitance of a capacitor. One is to increase the size of the plates. Another is to move the plates closer together.
About Photovoltaic Energy StorageSince we know that the (uncorrected) reactive power is 119.998 VAR (inductive), we need to calculate the correct capacitor size to produce the same quantity of (capacitive) reactive power. Since this capacitor will be directly in parallel with the source (of known voltage), we''ll use the power formula which starts from voltage and reactance:
