AC Transfer Voltage
During normal operation, the inverter supplies AC power to the applied loads through the
pass-through circuit and simultaneously charges the system batteries. Whenever the
external AC source drops below the AC Transfer Voltage (set by the potentiometer), the
inverter switches to battery power in order to maintain the connected load.
Examples (120 VAC inverter system):
The AC Transfer Voltage potentiometer is set to 9:00 oclock with ODP disabled. Whenever
the incoming AC voltage drops to 40 volts or below, the inverter will switch to battery power.
The AC Transfer Voltage potentiometer is set to 2:00 oclock with ODP enabled. Whenever
the incoming AC voltage drops to 105 volts or below, the inverter will switch to battery power.
NOTE: ODP does not affect the operation of the AC Transfer Voltage. ODP is either ON or OFF,
depending upon the position of the potentiometer.
NOTE: There are 6 settings available for the AC Transfer Voltage for both ODP OFF and ON as
shown in the Table 9 below.
NOTE: To achieve the fastest transfer time (typically less than 16 ms), set the AC Transfer Voltage
potentiometer near the 2:00 oclock position (with the ODP enabled); or, near the 1:00 oclock
position (with the ODP disabled). If a high number of nuisance transfers caused by transients on
the AC line occur, adjust the potentiometer from the maximum position toward the minimum position
(i.e., 2 oclock toward 5 oclock with ODP enabled; or 1 oclock toward 9 oclock with ODP disabled).
