Table 3.1, Battery Amphrs To Absorb Charging Time - Magnum Energy ME-MR Series Owner's Manual

• SETUP: 03 Batt AmpHrs - Used to select the most approximate capacity
of the battery bank connected to the inverter. This setting determines the
time the battery charger is in the Absorb Charging stage (i.e. Absorption
Time). See Table 3-1 to correlate the battery capacity to the Absorption
Time.
Default setting: Batt AmpHrs= 400

Table 3.1, Battery AmpHrs to Absorb Charging Time

Battery AmpHrs Selected
Batt AmpHrs = 200
Batt AmpHrs = 400
Batt AmpHrs = 800
Where do I set the Battery Amp-Hour setting? Select the setting based
on the 20-hour Amp-Hour (AH) capacity of your battery bank.
How do I determine my Battery Amp-Hour capacity? The inverter
requires deep cycle batteries, which are specifi cally made for continuous
use. Deep cycle batteries are rated either by a) amp-hours or b) 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 25%.
