Once you’ve determined the amp-hour capacity of each battery, review how
your batteries are connected (parallel or series) to determine the total amp-
hour capacity of the battery bank:
Table 3-2, Battery AmpHrs Capacity to Suggested Absorb Time
How do I determine my Battery Amp-Hour capacity? The inverter
requires deep cycle batteries, which are specifi cally made for continuous
use. The batteries are rated either by AHrs or reserve capacity in minutes.
•
Amp-hour (AH) capacity is a measurement of how many amps a battery
can deliver for a specifi ed length of time (usually 20 hours) until the
voltage achieves 1.75 VDC/cell at 80° F.
• Reserve Capacity (RC) is a measure of how many minutes a battery can
deliver a certain amount of current (usually 25A) and maintain a voltage
above 1.75 VDC/cell at 80° F.
Info: If using the Reserve Capacity (25A), the 20-hour AH capacity
can be estimated by multiplying ‘minutes reserve capacity’ by 50%.
Table 3-3 provides an estimated 20-hour amp-hour capacity based on the
group/code size, physical size, and voltage of the battery. If you are not
sure of your battery’s 20-hour AH rating, consult your battery manufacturer/
dealer or use the table below to obtain an estimate.
