a. ON/OFF Switch

.  

This switch controls ON/OFF operation of the inverter. 
 
 

b. OVER HEAT INDICATOR 
 

The Over Temperature LED will turn RED and the inverter will automatically 
shut down if the inverter shuts down because of inadequate ventilation or 
excessive load. If this occurs, turn OFF the inverter and   check that the 
ventilation openings are not blocked. Then check that the continuous power 
requirement of the appliance load does not exceed 8000 watts.  After the shut 
down condition is removed, turn on the inverter. When the inverter cools to a safe 
temperature, it will automatically restart. 

c. OVER LOAD INDICATOR.  

This indicator turns RED as the inverter shuts down. Immediately turn off some 
appliances if this occurs. The inverter will automatically restart. 

 

d. BAR GRAPH METERS.  
 

The inverter is equipped with digital bar meters that display DC input voltage and 
DC current drawn to indicate system operation. These meters are there to assist

diagnosis if there are DC power supply problems.  
DC voltage reading is the measurement of the voltage between the DC input 
terminals of the inverter, not the actual battery voltage. During high wattage 
applications the display may show a lower voltage level than the battery because 
of the voltage drop that occurs between the input cables and the battery. This 
voltage drop should not be excessive as this will seriously reduce run time. This 
inverter will operate with input voltage ranging from 11 to 15 Volts of direct 
current (DC). If the inverter input voltage level falls below 10.5 Volts DC, an 
audible alarm will sound. Should the voltage drop below 10 Volts DC, the 
inverter will automatically shut down.  

During charging from a generator, solar panel, or AC powered charger, the 
battery voltage will be higher than when there is no load on the batteies. This 
inverter will shutdown if the input voltage is 15 Volts. It will shut down 
automatically if this occurs, however, in some rare cases voltages greater than 15 
may cause damage to the inverter. Damage caused by excessive voltage input is 
not covered under warranty.  

The DC Current Meter indicates the current drawn by the inverter with the present 
DC load operating. The current displayed is the sum of currents supplied to all the 
DC input terminals. The meter should show minimal current drawn when the 
inverter is operating and all AC loads are turned off.  

e.

 

Four 115V AC Outlets

.  

Each outlet will supply l5A (1600 watts) 115V AC maximum, for powering 
appliances. Exceeding l5A of continuous power from an outlet may cause damage 
to the inverter and cause possible injury.  

f. High Wattage AC Outlet 

There are three insulated terminals on the front panel of the inverter. These 
terminals are for connecting 115 Volt AC devices that require more than 15 amps 
to operate. Other uses are for connection to distributed wiring that has multiple 
AC outlets. Any wiring that is directly connected must be 6 gage or larger. 
Terminal connections from left to right are:
