Go Power! SW150, SW300 Inverter
Owner’s Manual

Caution!
The negative DC input of the power inverter is connected to the chassis. Do not install the
power inverter in a positive ground DC system. A positive ground DC system has the
positive terminal of the battery connected to the chassis of the vehicle or to the grounding
point.
5. Operation
To operate the power inverter, turn it on using the ON/OFF switch on the front panel. The
power inverter is now ready to deliver AC power to your loads. If you are operating
several loads from the power inverter, turn them on separately after the inverter has been
turned on. This will ensure that the power inverter does not have to deliver the
starting-currents for all the loads at once.
5.1 Operating On/Off Switch
The ON/OFF switch turns the control circuit in the power inverter ON and OFF. It does
not disconnect power from the power inverter.
When the switch is in the OFF position, the power inverter draws no current from the
battery. When the switch is in the ON position but with no load, the power inverter draws
approximately 0.20 A from the battery.
5.2 Power Status
The power status LED indicates the operating state of the inverter. If the LED is green,
then the inverter is in operational mode and producing approximately 115 V AC. If the
LED is red or flashing red, then the inverter is in fault mode and there is no AC output.
Some common faults include:
5.2.1 Over voltage indicator (Red LED Blinking Fast)
The over voltage indicator indicates that the power inverter has shut itself down because
its input voltage has been over 16.5 VDC for the 12 V and 32.0 VDC for the 24 V.
5.2.2 Under voltage indicator (Red LED Blinking Slowly)
The under voltage indicator indicates that the power inverter has shut itself down because
its input voltage has been lower than 10.0 VDC for the 12 V and 20.0 VDC for the 24 V.
5.2.3 Over temp indicator: (Red LED Blinking Intermittently)
The over temp indicator indicates that the power inverter has shut itself down because it
has become overheated. The power inverter may overheat because it has been operated
at power levels above its rating, or because it has been installed in a location which does
not allow it to dissipate heat properly. The power inverter will restart automatically once it
has cooled off.
5.2.4 Overload indicator: (Red LED Solid)
The overload indicator indicates that the power inverter has shut itself down because its
output circuit has been short circuited or drastically overloaded. Switch the ON/OFF switch
to OFF, correct the fault condition, and then switch the ON/OFF switch back to ON.
5.3 Resetting Faults
Any of the inverters protection faults can be re-set by turning the inverter off for five
seconds and then turning the inverter on again. The GP-SW150 can also re-set any of its
protection faults using the optional remote on/off switch to turn the inverter off and then on
again.
