4. 15 amp GFCI Duplex Receptacle.
5. Automatic shutoff for low or high battery voltage, overload or over temperature with indicator LEDs.
6. Remote control circuit. (Not present on 600-watt models.)
7. Indicator lights for Low Battery Shutoff, Over Temperature Shutoff, Overload and Inverter ON/OFF/Load
Demand status.
8. Thermostatically controlled cooling intake fan.
Definitions
Load Demand Feature and Load Demand Mode:
The Load Demand Feature is an energy conserving feature which allows the inverter to enter the ‘Load Demand
Mode’ whenever the inverter is ON and the AC load has been less than 10 watts for approximately 10 seconds.
While in the ‘Load Demand Mode’ the inverter does not produce 120 volts AC but instead produces pulses of
voltage which the inverter uses to look for a load. When a load greater than 10 watts is sensed, the inverter will
turn fully ON to produce 120 Volts AC. The ‘Load Demand Mode’ is often also described as ‘stand-by mode’ or
‘sleep mode’. While in the ‘Load Demand Mode’ 12-volt models consume approximately 0.1 amps of DC and 24-
volt models consume approximately 0.05 amps of DC.
Load Demand can be turned off by setting factory setup DIP switch #4 to the up position.
