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]
