Protected 

from 

battery 

gases 

Do not operate where it will be exposed to battery 
gases. Prolonged exposure can damage the inverter. 

 

The inverter should be connected to your 

vehicle’s 12V power supply with the DC cables. We 

recommend that the equipment or appliance switch be in the OFF position prior to plugging into the 
AC receptacle of the inverter. 

Operating Instructions 

WARNING

 

Before connecting, make sure the cables will be connected correctly. If the poles of the battery are 
reversely connected, the inverter will be damaged and the warranty does not cover such damage.

 

 

1.  Turn on inverter.  

2.  Plug in AC appliances one at a time with the highest load first. 

3.  Before disconnecting the inverter from the battery, make sure the inverter is turned OFF.  

Note

: If connected to a vehicle battery, constant use of the inverter will greatly affect the life of the 

battery. Most vehicle batteries are not designed for constant deep discharge. If you plan to use the 
inverter for frequent extended periods of time, please consider using a separate battery for the 
inverter. 

Note:

 Please keep in mind most devices require an initial surge of power to start. Most devices can 

be started up with two times their power rating. Be aware of the start-up power of the device(s) you 
intend to use for the inverter. This inverter has the start-up capacity two times of rated power. The 
combined loads must not exceed rated power. The less combined wattage used, the longer the 
inverter will operate before recharging the battery is required. 

After Each Use 

When the inverter is not in use, disconnect the DC cable clips from the battery to prevent slight 
discharge of battery. 

Maintenance 

The inverter will operate efficiently when maintained properly. 

 

Clean the exterior surface of the inverter with a damp cloth to prevent accumulation of dust 
and dirt. 

 

Tighten the screws on the DC input terminals. 

 

Recharge the battery before it is discharged to 50%. This will extend the durability and 
efficiency of the battery.
