Introduction 

Congratulations on your purchase of the STP-150 Power Inverter. It 

lets you provide two outlets for 115 Volts AC anywhere you have 12 
volts DC; in your car, truck, RV or boat.  It is designed to be easy to 
use and provide years of dependable service.

 

 

IMPORTANT SAFETY NOTE 

Read all the Cautions and Warnings before installing and using the 

power inverter. The inverter must be properly installed. If you are not 
familiar with 12 volt, high-current wiring, it is recommended that you 
have a professional automotive installer install the inverter. 

 
Cautions 

• 

The STP-150 generates 115 Volts AC power from your 12 volt 

car battery.  Treat the 115 Volt AC output just like you treat 
the 115 Volt AC in your house.  It is just as dangerous. 
Keep away from children. 

• 

With heavy use, the unit will become warm and possibly hot. 

Keep it away from any heat sensitive materials. 

• 

Do not connect the unit to AC distribution wiring. 

• 

Keep the unit away from water. Do not allow water to drip or 

splash on the STP-150 

• 

Keep the unit in cool environments. Ambient air temperature 

should be between 40

o

 and 80

o

 F. Do not block vent holes. 

• 

Keep out of direct sunlight and away from heating vents. 

• 

Keep the unit away from flammable material or in any location 

which may accumulate flammable fumes or gases, such as the 
battery compartment of your car, boat, RV or truck.

 

 

 

Health Advisory 

Sima Products does not authorize the use of the STP-150 with any

Key Features 

The STP-150 is designed for high-efficiency operation to 
provide the most output with the least battery power usage. 

 
Advanced protection

 

• 

Thermal Protection

 shuts the unit off to guard against 

the unit getting too hot 

• 

Overload Protection

 protects the unit from excessive 

loads 

• 

Under Voltage Protection

 turns the unit off to protect 

the battery from being over discharged 

 
This Sima power inverter produces a modified sine wave output 
which is suitable for most AC loads.  This includes lights, 
appliances, motors, TVs and most electronics. 

 
CAUTION

:  There are a few battery chargers that are not 

compatible with modified sine wave operation. These are 
typically small rechargeable, battery-operated devices like razors 
and flashlights that can be plugged directly into an AC receptacle 
to recharge.   

Some chargers for battery packs used in power tools also 

should not be used with an inverter. These chargers typically 
have a warning label indicating that dangerous voltages are 
present at the battery terminals. Only a true sine wave inverter 
should be used with these types of appliances. Damage to the 
device could result if you attempt to use them with any type of 
modified sine wave inverter. 

 

Warning: Do not use the Sima power inverter 
                 with the devices mentioned above!
