Battery Capacity
The Battery Capacity potentiometer is used to set the correct charge profile for the
battery capacity (amp-hours) used with the inverter (see illustration below). The
setting allows the inverter to calculate over-discharge protection values and also
the end of the Bulk/Absorption charge mode, at which point the inverter switches
to the Float mode of battery charging.
The potentiometer should be adjusted as close as possible to the actual capacity of
the battery bank for optimum charging. If the system’s battery bank is larger than
1000 amp-hours, set the potentiometer for 1K.
Important:
If using dual inverters configurations, set each charger for half the value.
Important:
Most battery manufacturers list the amp/hour rating on the battery label.

Important:
The Battery Capacity (Amp/Hrs) potentiometer values have changed
between the minimum value of 50 Ah and 1 kAh. Please use the photo that matches your
unit.
