Instructions for GPSW Inverter 150-300



Where to Install


The inverter should be installed in a location that meets the following requirements:



Do not connect the 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 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), available from Go Power!


a) Dry - Do not allow water to drip or splash on the inverter.


b) Cool - Ambient air temperature should be between 32 and 104 °F (0 and 40 °C); the cooler the better.


c) Ventilated - Allow at least 2 inches (5.08 cm) of clearance around the inverter for air flow. Ensure the ventilation openings on the rear and bottom of the unit are not obstructed.


d) Safe - Do not install the inverter in the same compartment as batteries or in any compartment capable of igniting flammable liquids such as gasoline.


e) The inverter location should not exceed 10 feet (3.05 m) of the batteries.


Installation and testing


The following procedure describes how to install and test the GPSW150 and GPSW300 inverters.


1. Unpack and inspect your Go Power!TM Inverter. Ensure that the power switch is in the OFF position.


2. Connect power: GPSW150: Attach the automobile DC plug to a DC socket; go to step 7.

Ensure there is circuit protection on the DC socket; see section 0 4.3 Cables. If the DC plug is removed showing the negative and positive wires, go to step 3. GPSW300: Plug in the Anderson Power Pole connectors; go to step 3.


3. Securely connect the negative cable (black) to the negative terminal of the battery.

CAUTION: Loose connections result in excessive voltage drop and may cause overheated wires and melted insulation.

CAUTION: A reverse polarity connection will blow a fuse in the inverter and may permanently damage the inverter. Damage caused by reverse polarity connection is not covered by the warranty.


4. Before proceeding further, carefully check to ensure that the cable connects from the negative DC input of the inverter to the negative terminal of the battery.

CAUTION: You may observe a spark when you make the positive 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.


5. Install the recommended inverter fuse in the positive lead; see section 4.3 Cables. The fuse should be located as close to the battery as possible. Ensure all connections are tight and secure.


6. Securely connect the positive cable (red) to the positive terminal of the battery.


7. Set the power switch to the ON position. Check the indicator LED on the front panel of the inverter to ensure that it is green.


8. Set the inverter switch to the OFF position. The indicator light 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.


9. Set the inverter switch to the ON position and turn on the test load; 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.




To operate the inverter, turn it on using the ON / OFF switch on the front panel. The inverter is now ready to deliver AC power to your loads. If you are operating several loads from the inverter, turn on the inverter, and then turn on each load separately. This will ensure that the inverter does not have to deliver the starting-currents for all the loads at once.


Operating On / Off Switch


The ON / OFF switch turns the control circuit in the inverter ON and OFF. It does not disconnect power from the inverter.


When the switch is in the OFF position, the inverter draws no current from the battery.

When the switch is in the ON position, but with no load, the inverter draws approximately 0.20 A from the battery.




Clean the exterior of the unit periodically with a damp cloth to prevent accumulation of dust and dirt and check all connections between the battery and inverter.
