Type:	Output Variable
Units:	hr
Symbol:	Abatt

The storage bank autonomy is the ratio of the storage bank size to the electric load. HOMER calculates the storage bank autonomy using the following equation:

equations_A_batt

where:
	Nbatt	= number of batteries in the storage bank
	Vnom	= nominal voltage of a single storage [V]
	Qnom	= nominal capacity of a single storage [Ah]
	qmin	= minimum state of charge of the storage bank [%]
	Lprim,ave	= average primary load [kWh/d]
