Installation Precautions for GP Inverter 225-1000HD
1. Do not install the Inverter into a building’s electrical system. The Inverter is a vehicular accessory. It 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 an indoor well-ventilated area and do not cover ventilation openings or cooling fans. Do not install in engine compartment. Avoid placing the Inverter on carpets and rugs; they are not only flammable, but they also obstruct vents underneath the Inverter.
3. Keep combustible materials and gases away from the Inverter. The Inverter produces sparks and heat during operation and could start a fire.
4. Connect to a 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 the 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 the 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 the Inverter as close to the 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 ignited by the Inverter.
10. Mount the Inverter horizontally.
11. Verify that the 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 RVs have negative ground systems).
14. 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 the final connection. This is normal.
15. Properly ground the Inverter’s case as explained in this manual.
Where to Install
Your Inverter should be installed in a location that meets the following requirements:
1. Dry: do not allow water to drip or splash on the Inverter.
2. Cool: ambient air temperature should be between 0°C and 40°C (the cooler the better).
3. Ventilated: allow at least two inches of clearance around the inverter for airflow. Ensure the ventilation openings on the rear and bottom of the unit are not obstructed.
4. Safe: do not install the Inverter in the same compartment as batteries or in any compartment capable of igniting flammable liquids such as gasoline.
5. The Inverter should be located within 10 feet of the batteries.
GP-225HD Installation & Testing
IMPORTANT: most North American car lighters are rated between 10-15 Amps DC and are fused in the automobile fuse box.
CAUTION! Equipment Damage.
Do not connect this Inverter and another AC source (generator or utility power) to the AC wiring or AC loads at the same time. Doing so will destroy the Inverter and void the warranty, regardless of whether the Inverter is switched on or off. If you are using more than one AC source for the AC wiring or AC loads, it is highly recommended that you install an automatic transfer switch (GP-TS, TS-30, or TS-50), available from Go Power!
Please consult your automobile owner’s manual for the fuse rating of your lighter. It is recommended that you DO NOT exceed the load capability your vehicles electrical system, or modify the size of the fuses installed by the manufacturer.
1. Unpack and inspect your Inverter, and make sure the power switch is in the OFF position.
2. Insert DC input plug into any 12 VDC car lighter receptacle.
3. Set the Inverter switch to the ON position. The power status LED should be green.
4. Set the Inverter switch to the OFF position. The indicator lights may blink and the internal alarm may sound momentarily. This is normal.
5. Ensure the test load switch is OFF. Plug the test load into the AC receptacle on the front panel of the Inverter.
6. Set the Inverter switch to the ON position and turn the test load on; the Inverter should supply power to the load.
Note: if you plan to measure the output voltage of the Inverter, a true RMS meter must be used for accurate readings.
GP-400/800/1000HD Installation & Testing
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.
1. Unpack and inspect the Inverter, and make sure the power switch is in the OFF position.
Note: we recommend using Go Power! DC Install Kits when installing a Go Power! Inverter (sold separately). Check section 4.7 DC WIRING SIZE to determine what Install Kits works for your Inverter.
2. Connect the DC Inverter cables into the power input terminals on the back of the Inverter. Remember, the (+) terminal is positive and the (-) terminal is negative. Place the lug connector between the washers and tighten the terminal screw or nut to clamp the wires securely. Ensure connections are tight.
3. Connect the ground cable to the appropriate location; see article GP Inverter 225-1000HD: DC Wiring for more information.
CAUTION! Equipment Damage. Loose connections result in excessive voltage drop and may cause overheated wires and melted insulation. Ensure connections are tight.
4. First, connect the DC Inverter cables from the negative terminal of the Inverter to the negative terminal of the battery. Make sure the connection is secure.
5. Before proceeding further, carefully check that the cable you just connected is going from the negative terminal of the Inverter to the negative output terminal of the battery.
6. Install the Inverter fuse into the positive lead. The fuse should be located within 12” (31 cm) of the battery. Ensure all connections are tight and secure.
7. Connect the cable of the positive terminal of the Inverter to the positive terminal of the battery. Make a secure connection. Check your polarity.
WARNING! Fire/explosion Hazard. You may observe a spark when you make the final battery connection since current may flow to charge capacitors in the Inverter. Do not make this connection in the presence of flammable fumes, as explosion or fire may result.
CAUTION! Equipment Damage. This Inverter cannot supply power to any AC distribution wiring or AC loads in which the neutral and ground are connected (bonded). Doing so will destroy the unit and void the warranty. If you do not understand neutral to ground bonding, please have a professional install your system for you. See article GP Inverter 225-1000HD: DC Wiring for more information.
8. Set the power switch to the ON position. Check the meters and indicators on the front panel of the Inverter. The Function LEDs should be green showing the Inverter is ON. If it does not, check your battery bank and the connections to the Inverter. The other indicators should be OFF.
9. Set the Inverter switch to the OFF position. The indicator lights may blink and the internal alarm may sound momentarily. This is normal. Plug the test load into the AC receptacle on the front panel of the Inverter.
10. Set the Inverter switch to the ON position and turn the test load on; the Inverter should supply power to the load. If you plan to measure the output voltage of the inverter, a true RMS meter must be used for accurate readings.
