3.1 Rear view – GP-300
a) Ventilation port:
Do not obstruct, allow at least 1 inch for air flow.
b) Battery terminals: Connect to 12 V battery or other 12 V power source. Note
that “+” is positive, “-” is negative. Reverse polarity connection may damage in
verter permanently.
Note: Minimum inverter DC cable & DC inverter fuse sizes, see section 4.3 and 4.4.
4. Installation
4.1 Where to install
The power inverter should be installed in a location that meets the following require-
ments:
Caution! 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 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 Electric Inc.
a) Dry - Do not allow water to drip or splash on the inverter.
b) Cool - Ambient air temperature should be between 0°C and 40°C (the cooler the
better).
c ) Ventilated - Allow at least two inches of clearance around the inverter for air
flow. Ensure the ventilation openings on the rear and bottom of the unit are not
obstructed.

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 Controls and indicators
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 idle
current is approximately 1 A (see product specifications for exact current draw).
6. Operating limits
6.1 Overtemp
The fault LED will come on when the inverter has shut itself down because the
inverter has become overheated. The power inverter may overheat because it has
been operated at power levels above it’s 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.
6.2 Overload
The fault LED will come on when 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.
Some induction motors used in refrigerators, freezers, pumps and other motor oper-
ated equipment require very high surge currents to start. The power inverter may not
be able to start some of these motors, even though their rated current draw is within
the power inverter.
If the motor refuses to start, observe the battery voltage indicator while trying to
start the motor. If the battery voltage indicator drops below 11 volts while the
inverter is attempting to start the motor, this may be why the motor will not start.
Make sure that the battery connections are good and that the battery is fully
charged. If the connections are good and the battery is charged, but the voltage
still drops below 11 volts, you may need to use a larger battery.
6.3 Input voltage
The power inverter will operate from input voltage ranging 10 V – 15 V. If the voltage
drops below 10.7 V, an audible low battery warning will sound and the fault LED will
be on. The power inverter will shut down if the input voltage drops below 10 V. This
protects your battery from being over discharged.
The power inverter will also shut down if the input voltage exceeds 15 V. This
protects the inverter against excessive input voltage. Although the power inverter
