Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this
manual including all text under subheadings therein before set up or use of this product.
TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
Make sure that the Power Switch is in the off-position and unplug the tool from
its electrical outlet before performing any procedure in this section.
Note: For additional information regarding the parts listed in the following pages,
refer to Parts List and Diagram on page 11.
CAUTION! This Inverter must only be connected
to batteries with a output voltage of 12 volts DC.
Lower voltage will not operate the Inverter properly,
and more voltage could damage the Inverter
or the device being powered. Do not use this
Inverter with positive ground electrical systems.
The Inverter is configured to have a number of
shut-down points, for the safety of the operator,
the unit, and the devices being used with it.
• If the DC input voltage drops too low, the
alarm on the Inverter will sound. Should the
input voltage drop further, the Inverter will
shut down automatically to prevent permanent
battery damage. Recharge the battery soon.
• If the DC input voltage exceeds 15V the
Inverter will shut down automatically.
• If the output load power rises higher
than the rating power of the Inverter; the
unit may shut down automatically.
• The Inverter may automatically shut down
if its internal temperature gets too high.
Note: Even though this inverter has built-in mechanisms
to minimize damage, these situations should be avoided
because they can still damage the inverter or battery.
1. Place the Inverter on a dry, level, non-flammable,
stable surface. Make sure the Inverter has
adequate ventilation and is not in direct sunlight.
2. Connect one end of a ground wire (not included,
use at least recommended wire thickness from
specification sheet) to the wing nut located on the
back of the Inverter. Then connect the other end
of the ground wire to a paint/rust free grounded
metal surface, such as the vehicle chassis.
3. Battery Type Selection:
• Use only deep cycle lead-acid batteries with this
inverter, such as 12 volt marine/RV deep-cycle
batteries. Do not use automotive, engine starting
(SLI), or maintenance-free wet cell batteries with
this inverter; they are designed for repeated,
shallow discharge and will wear out quickly.
• Gel and AGM (Absorbed Glass Mat)
batteries can be used with this inverter, but
they require special charging procedures.
Refer to battery supplier’s instructions.
4. Battery capacity selection:
about 1 hour
about 4 hour
500W 80 Ah 200 Ah
1000W 150 Ah 400 Ah
1500W 240 Ah 700 Ah
2000W 300 Ah 1000 Ah
3000W 450 Ah 1500 Ah
4000W 600 Ah 2000 Ah
5000W 750 Ah 2500 Ah
Consult the chart above for approximate run
time at different battery capacities. If the battery
does not have a capacity this large individually,
use a bank of batteries as explained below.
5. Battery Bank assembly instructions:
a. Read the following safety rules before
assembling the battery bank:
• Connect batteries in parallel (negative
terminals together to one cable;
positive terminals together to the
other cable) as shown in Battery
Bank Example illustration ONLY.
• Do not connect 12V batteries in series (from
negative of one battery to the positive of the
next). This connection can result in voltage
high enough to cause ELECTROCUTION.
• Wear splash-resistant ANSI-approved
safety goggles and electrically insulated
gloves while assembling battery bank.
• Only connect similar batteries together in a
battery bank. Do not connect old and new
batteries together, wet and gel cells together,
or batteries of different capacities together.
• Connect all batteries in the battery bank together
using cables of the thickness recommended on
the specification sheet or thicker. Since amp
draw on this low-voltage circuit will be very
high, thinner cables present a fire hazard.
