The Storage tab in the Simulation Results window contains the following output variables.
Variable 
Description 
Batteries 
The number of batteries in the array is the string size multiplied by the number of strings 
String Size 
The number of batteries connected in series in each string 
Strings in Parallel 
The number of storage strings connected in parallel 
Bus Voltage 
The voltage of the storage array, calculated by multiplying storage voltage by string size, in volts 
The capacity of the storage bank divided by the average electrical load, in hours 

The cost of cycling energy through the storage bank, in $/kWh 

The amount of energy that could be withdrawn from the storage at a particular constant current, starting from a fully charged state, in kWh 

Usable Nominal Capacity 
The storage capacity adjusted to exclude all capacity below the minimum state of charge of the storage, in kWh 
The total amount of energy that can be cycled through the storage before it needs to be replaced, in kWh 

The number of years the storage bank will last before it requires replacement 

Average Energy Cost 
The average cost of the energy that goes into the storage, in $/kWh 
Energy In 
The total amount of energy charged to the storage, in kWh 
Energy Out 
The total amount of energy discharged from the storage, in kWh 
Storage Depletion 
The difference in the storage state of charge at the beginning and end of the year, in kWh/yr 
Losses 
Annual energy losses due to storage inefficiency, in kWh/yr 
The total amount of energy that cycled through the storage bank during the year, in kWh/yr 
In the bottom half of the page a DMap appears showing the state of charge of the storage bank in each time step of the year. Below is an example of Storage output in HOMER Grid.

Variable 
Description 
The maximum power (kW) that the battery can be charged in each time step. The actual power output is less than or equal to this amount. 

The maximum power (kW) that the battery can supply (the actual power output is less than or equal to this amount). The battery contributes this amount to the operating capacity. 

Charge Power 
The charge power (kW) in each time step. The charge power is zero if the battery is being discharged. 
Discharge Power 
The output power (kW) that the battery supplies. The discharge power is zero if the battery is being charged. 
Input Power 
The power flow (kW) in or out of the battery. Positive is charging, negative is discharging. This is equivalent to the Charge Power when the battery is charging, and to the negative of the Discharge Power when the battery is discharging. 
Energy Content 
The total energy currently stored in the battery, in kWh. 
State of Charge 
The energy currently stored in the battery, as a percentage of the maximum capacity of the battery. 
The average marginal cost of energy added to the storage bank in cost per kWh. This value is used in dispatch decisions. 

Temperature 
The internal temperature of the battery in Celsius (Modified Kinetic Battery model only). 
Degradation  Time and Temperature 
The degradation of the battery due to age and temperature history. This value works with the DegradationCycling value to determine the performance degradation of the battery and replacement time (Modified Kinetic Battery model only). 
Degradation  Cycling 
The degradation of the battery due to use. This value works with the value Degradation  Time and Temperature to determine the performance degradation of the battery and replacement time (Modified Kinetic Battery model only). 
Equivalent Cycles 
The cumulative count of total equivalent full cycles of the battery computed with the Rainflow counting algorithm (Modified Kinetic Battery model only).
