Battery Bank — Size and Example
To select the correct battery bank size you must determine the amount of total watts
(load) and how long the load needs to operate. This can vary depending on your
needs, applications, and appliances.

NOTE: This is a general Running Watt guide. Be sure to verify the correct Power Consumption & Surge of your appliances.
• A watt-hour is the Voltage (V) multiplied by the Current (Amps) that the battery
can provide during a period of use known as Amp Hours (AH).
• Using the equation below multiply the Volts (V) of your battery by the Amp
Hours (AH)
of each battery to determine total
Watt Hours (WH)
.
For an example of a rough estimate on appliance runtime, use the provided
information above in conjunction with the example of 12V applications table on
the next page.

Battery Size: The total Watt Hours (WH) determines the size of the battery.
V x AH = WH
In this example we used one 12V 100Ah battery to determine its Watt Hours.
(For more than one battery use: WH x the number of batteries)
