Thank you for purchasing this 8,000 Watt DC to AC Power Inverter by Wagan Tech. With
minimal care and proper treatment it will provide years of reliable service. Carefully read,
understand and comply with all instructions before use. Keep this manual for future reference.
ABOUT THIS INVERTER
This power inverter converts 12 volts, direct current (12V DC) to 115 volts alternating household
current (115V AC). It easily powers TV/VCR combinations, microwave ovens, refrigerators, even
air conditioners! It also operates at highest efficiency (up to 90%) which results in longer running
time and extended battery life compared to other inverters with this power.
This inverter has the highest surge capability in its class. Superior surge capability allows the
inverter to start the most difficult motorized loads. Advanced, microprocessor-controlled circuits
run cooler and, therefore, are more reliable than competing units.
GENERAL INSTRUCTIONS
• Keep the inverter away from any direct heat source or combustible materials or gases.
• Keep well ventilated–this device generates heat.
• Do not operate any equipment over 8,000 watts.
• This inverter will only operate from a 12-volt DC power source.
• Do not attempt to connect the inverter to any other power source, including any AC
power source.
• Incorrect battery polarity will damage the inverter and void the warranty.
• Keep this inverter in a dry environment.
• Do not open the inverter; there are no user serviceable parts inside.

LOAD CONSIDERATIONS
When a motorized appliance motor starts, it requires an initial surge of power. This surge of
power is called the “starting load” or “peak load”. Once started, the appliance requires less
power to continue to operate. This is known as the “continuous load”. It is important to know the
starting loads and the continuous loads of the appliances that are to be powered by the inverter.
Appliance power is rated in watts. This information is usually stamped or printed on most
appliances and equipment. In some cases, a tool will be rated in amperes. To convert from amps
to watts, multiply: AMPS X 115 (AC voltage) = WATTS. This formula yields an approximation of
the continuous wattage load of the appliance.
The start up load of an appliance is a major factor of whether this inverter can power it. Start-up
load is momentary. With many devices, it is approximately twice the continuous load. However,
with some devices start-up load can be as high as eight times the continuous load. To determine
if an appliance or tool will operate with this inverter, run a test. This inverter is designed to
automatically shut down in the event of an output overload, so there is no danger of damaging
either the inverter or the equipment.
This inverter may not properly operate some devices with either speed control features or dimmer
controls. Some appliance GFCI power cords will not operate properly while powered by this
inverter. Again, the only way to be sure of proper operation, is to try it.
If an appliance within the 8,000 watt range will not operate properly, it is likely that the inverter
system does not have the required output to operate that appliance.
SAFETY WARNING. THE INVERTER OUTPUT CAN BE LETHAL. IMPROPER USE OF THIS INVERTER
MAY RESULT IN PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OF LIFE.

FRO NT PANEL
The Front Panel view shows the inverter’s On/OFF Switch, indicators, AC outlets and direct wiring
high current terminals.
1. ON/OFF Switch
This switch controls ON/OFF operation of the inverter.
2. 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 8,000 watts. After the shut
down condition is removed, turn on the inverter. When the inverter cools to a safe temperature, it
will automatically restart.
3. 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.
4. 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.
5. Ground Terminal
This connection is for connecting to a 6 gage insulated ground wire. Do not directly connect this
ground connection to the Negative DC terminal. This is described in the installation procedure.
6. Four 115V AC Outlets
Each outlet will supply 15A (1,600 watts) 115V AC maximum, for powering appliances.
Exceeding 15A of continuous power from an outlet may cause damage to the inverter and cause
possible injury.

7. AC Output Terminals
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:
