Customer ServiceThe required battery bank capacity (B r) is obtained as (7) B r = max {Q B (t)} DOD where DOD is the allowable depth of discharge of the battery. The proposed procedure provides the value of the minimum diesel generator capacity ( P = P min ) and the corresponding capacity of the battery bank ( B ).
Customer ServiceIn order to determine the energy required from the PV array, it is necessary to increase the energy from the battery bank to account for battery efficiency. The average round-trip energy efficiency of a new battery is 80–85 % (variations in battery voltage are not considered). Therefore, the energy required, which needs to be provided by the solar PV array, is

The quantity of electricity that the battery can deliver in amp-hours at the 8 hour rate. Replacement criteria = 80% of rated capacity. The initial rated capacity of the battery should be at least 125 percent (1.25 aging factor) of the load expected at the end of its service life. Batteries may have less than rated capacity when delivered.
The battery cells capacity is generally provided for a standardized temperature which is 25oC and if it varies somewhere with the installation temperature, a correction factor is needed to implement. Capacity rating factor This particular factor accounts for voltage reduction during the discharge of the battery.
Although many tests can be performed to assess the condition of the batteries such as ohmic testing, specific gravity, state of charge etc., only the capacity test, commonly referred to as the discharge or load test, can measure the true capacity of the battery system and in turn determine the state of heath of the batteries.
There are a number of different tests like: visual inspections, specific gravity, float voltage and current measurements, discharge test, individual cell condition, inter-cell resistance, and others, which are recommended in IEEE, NERC and other standards for diagnosing the condition of the battery banks.
At the completion of a capacity test, the measured capacity should be reviewed based upon sizing criteria used during installation to determine if the battery is still able to meet the load requirements. The most recommended practice is to replace the battery bank if measured capacity is less than 80% of manufacturer published ratings2.
