The typical vehicle battery has a minimum operating time of 1 to 2 hours, depending on
the current use of the load being driven. We recommend that the opeator start the vehicle
every hour to recharge the battery system. This will prevent unexpected shut downs of
equipment and will ensure that there is always sufficient battery capacity to start the engine.
Your power inverter circuitry constantly monitors the following hazardous conditions:
Low Battery Voltage — This condition is not harmful to the inverter, but could damage the
power source. An audible alarm is sounded when input voltage drops to 10.5 volts. The inverter
shuts down when input voltage drops to 10.0 volts. When the condition is corrected (i.e.
alternator charges battery). The unit may be restarted.
Short Circuit — Reverse polarity or short circuit condition of the load will usually
result in opening of the short circuit protecting.
High Temperature — When the temperature of the internal heat sinks reaches 150 degrees F, the
solid — state temperature sensor located in the power inverter will automatically shut down
the unit. Once it is allowed to cool, it may be restarted.
