Transfer Switch
The inverters come with a 20A/30A transfer switch that allows the inverters to switch
between AC shore power and AC inverter mode (DC to AC) in a matter of 10
milliseconds. The inverter will automatically switch to battery power when the AC input
voltage drops below 90VAC.

SW 1 (Low Battery Disconnect):
This switch can change the low battery disconnect between 10.0V-11.5V. Depending on
whether shore power is present or not the low voltage set point will change. For most
applications, the voltage should be set to 11.5V to prevent the batteries from being
depleted.
SW 2 (AC Input Range):
Most electronics have a recommended AC voltage range and staying within this range
will allow the electronic to function normally. Some electronics will function between
100-130VAC 60Hz while other accept a lower frequency 40-60HZ. If the AC source falls
below 50Hz or 100VAC then position 1 will need to be used.
SW 3 (Power Saver):
The inverter’s power saver mode is activated when position 1 is selected. The inverter
will detect a load for 250ms every 3 seconds and if a load is detected the inverter will start
outputting AC power. NOTE: If the switch position is set to 0 and power saver mode is
selected on the inverter main power switch, then no AC power will be outputted unless
there is shore power connected to the inverter.
SW 4 (Frequency Switch):
