Introduction 

Congratulations on your purchase of the STP-325 Power Inverter. It 

lets you provide 2 sources for 115 Volts AC anywhere you have 12 
volts; 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-325 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 children away from STP-325.  

• 

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-325 

• 

Keep the unit in cool environments. Ambient air temperature 

should be between 40 degrees and 80 degrees F. Do not block 
fan opening. 

• 

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-325 with 

any products to be used in life support devices or systems.

Key Features 

The STP-325 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 devices mentioned above!
