General Precautions

  1. The warnings, precautions, and instructions  People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure.
  2. discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factor that cannot be built into this product but must be supplied by the operator.

Installation Precautions

    This Inverter is a vehicular accessory. is not designed to be safely used in a building’s electrical system and has not been evaluated to meet building wiring codes. Improper application may create a fire or electric shock hazard.
  2. To allow proper cooling, install in indoor well-ventilated area and do not cover ventilation openings or cooling fins. Do not install in engine compartment. Especially avoid placing the Inverter on carpets and rugs; they are not only flammable, but they also obstruct vents underneath it.
  3.  Keep combustible materials and gasses away from the Inverter. The Inverter produces sparks and heat during operation and can start a fire.
  4. Connect to 12 VDC power supply only. A power supply with lower voltage will not operate the Inverter correctly, and higher voltage could damage the Inverter.
  5.  Connect input polarity properly. Incorrect connection will damage Inverter and void warranty.
  6. Do not use in a marine application. This Inverter is not intended to withstand the highly corrosive conditions in marine applications and would quickly be rendered inoperable or unsafe.
  7. Keep Inverter dry and clean. Do not expose to rain, snow, spray, bilge water or dust.
  8. Use cables that are thick enough. The more power (amps) or the longer the cables, the thicker they need to be to prevent overheating and fire.
  9.  Install as close to DC source as possible, but not in a closed area with vented lead-acid batteries. Vented lead-acid batteries release explosive hydrogen gas that can be
  10. Mount Inverter horizontally.
  11.  Verify that installation surface has no hidden utility lines before drilling or driving screws.
  12. This product is not a toy. Keep it out of reach of children.
  13. Do not use with positive ground electrical systems.(Most automobiles, trucks, and RV’s have negative ground systems.) The positive (+) battery on the Inverter must be the last connection made, and must be connected before the Inverter is turned on. There may be a small spark during thefinal connection. This is normal.
  14.  Properly ground the Inverter’s case as explained in this manual.

Battery Precautions

  1.  Wear splash-resistant ANSI-approved safety goggles and electrically-insulated gloves while working near batteries.
  2.  Charge, store, and maintain batteries according to supplier’s instructions.
  3.  Locate batteries in a clean, well-ventilated area, away from ignition sources and flammable materials. Vented lead-acid batteries release explosive hydrogen gas while charging.
  4.  Only connect similar batteries together.Do not connect old and new batteries together, flooded and gel cells together, or batteries of different capacities together.
  5. Use only 12 V batteries with this item.
  6. Connect batteries in parallel ONLY (negative terminals together to one cable; positive terminals together to the other cable).
  7. Install a properly rated fuse on the positive output of the battery bank.

Operation Precautions

  1.  Multiple outlet power strips with switches and circuit breakers only interrupt power to the “hot” receptacle terminals. The “neutral” terminals remain powered with respect to the “ground” terminals. So strip switch may be off, but part of device may still be powered.
  2.  Inspect supply connections before use to ensure they are tight and that insulation is not damaged.
  3.  Do not use this Inverter to power sensitive devices such as medical devices or computers. Do not use in ignition protected areas.
  4.  Some rechargeable devices can damage the Inverter. Check the temperature of the device several times when it is charging. If the device becomes extremely hot; turn the power off, remove the device, and do not use with the Inverter again.
  5.  Check for breakage of parts and any other condition that may affect the Inverter’s operation. If damaged, have it repaired before use.
  6.  If the Inverter is powered by a vehicle’s starting battery (not recommended), do not drive or move the vehicle if the Inverter is attached using alligator clips or another temporary means.
  7.  Do not attempt to power a device, or combination of devices, that will require more than the rated output of this Inverter. This may damage the Inverter or the attached devices.
  8. Appliances such as microwave ovens will normally draw more than their rated current. For example: A typical 600 watt microwave oven will draw approximately 1,000 watts.
  9. Do not attach a battery charger if the charger carries a warning that dangerous voltages are present at the battery terminals.
  10.  Some fluorescent lamps may not operate properly with this type of Inverter. If the bulb appears to be too bright, or fails to light, do not use the lamp with this Inverter.
  11. some fans with synchronous motors may slightly increase in speed when powered by the Inverter. This is not harmful to the fan or to the Inverter.
  12. The inverter will consume some power while on, even without loads attached. Turn Inverter off after use.

Service Precautions

  1.  DO NOT OPEN HOUSING. Contains no user-serviceable parts. Internal parts may be electrified, even with Inverter off and power disconnected.
  2.  Maintain labels and nameplates on the Inverter. These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
  3.  Have your Inverter serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the Inverter is maintained.
  4.  Fuses must be replaced with fuses of the same type and rating only.

Output Waveform

  1.  This Inverter’s output is a Modified Sine Wave.Power from most electric utilities is a Sine Wave. Note: Only multimeters identified as “TRUE RMS” will read Modified Sine Wave voltage accurately.Installation
  2.  Modified Sine Wave (MSW) power is suitable for most AC devices and power supplies used in electronic equipment, transform ers, and motors. Do not use to power sensitive devices such as medical equipment or computers. Some audio equipment may perform poorly if run on Modified Sine Wave power.
  3.  Sine Wave Inverters provide power that is identical to, or even better than, the power supplied by your power company. Motors start easier and run cooler under Sine Wave power. Certain devices, such as laser printers, variable speed motors and digital clocks, require sine wave power to operate properly. Sine wave Inverters are typically more expensive for their capacity than other Inverters.


Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document including all text under subheadings therein before set up or use of this product.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 has a number of shut-down points, for the safety of the operator, the Inverter, and the devices being used with it.

  •  If the DC input voltage drops too low, the alarm on the Inverter will sound. If the input voltage drops further, the Inverter will shut down automatically to prevent permanent battery damage. Recharge the battery soon.
  •  If the DC input voltage exceeds 15 V the Inverter will shut down automatically.
  •  If the output load power rises higher than the rating power of the Inverter, the Inverter 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 table) to the Ground Terminal located on the back of the Inverter. Then connect the other end of the ground wire to a paint/rust free grounded metal surface, grounding rod, or other appropriate ground source3. Battery Type
  3. 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:
Inverter Output about 1 hour

discharge time (Minimum battery capacity)

about 4 hour

discharge time (Optimal battery capacity)

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:

  •  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 ONLY.
  • Do not connect 12 V 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, flooded and gel cells together, or batteries of different capacities together.
  •  Connect all batteries in the battery bank together using cables of the thickness recommended in the specification table or thicker. Since amp draw on this low-voltage circuit will be very high, thinner cables present a fire hazard.
  •  Locate battery bank in a clean, well-ventilated area, away from ignition sources and flammable materials. Batteries release explosive hydrogen gas while charging.
  •  Charge, store, and maintain batteries according to the supplier’s instructions.
  • Connect the batteries in parallel as shown above. Connect all of the positive terminals to one another.
  •  Then connect all the negative terminals to one another.
  •  Connect the negative and positive output cables to opposite ends of the bank. Use two 2/0 AWG cables up to 3 feet long in parallel on each terminal. Do not allow the output cables to touch one another.
  • Test the voltages at the output cables to help ensure that the battery bank is properly wired. If the voltage is higher than 13 volts, then part of the battery bank is likely connected in series (a negative terminal of one battery attached to a positive terminal of another) instead of in parallel. Carefully examine the diagram and correct
    the wiring before attaching to the Inverter.
  •  Turn the Inverter’s Switch off.
  •  Connect the output cables from the battery bank to the Inverter.

Operating Instructions

  1.  Plug 120 VAC device(s) into the receptacles. Switch all devices off. The devices must not use more than the rated wattage during continuous operation, otherwise they may overload the Inverter.
  2.  Turn the Inverter’s Switch on.
  3.  Turn the device(s) on, one at a time. If the alarm sounds, turn off the device(s). Unplug the device(s) from the Inverter. Check the wattage of the devices, if there were multiple devices plugged in, discontinue use of one or more. If a single device set the alarm off, it is not appropriate for use with the Inverter.
  4. Inverter will consume some power while on, even without loads attached. Turn Inverter off after use.
