Connecting To A Vehicle Battery
- Mount the inverter inside the vehicle in a well-ventilated location close to the battery
- For safety reasons install a properly rated fuse (not included) on the red cable as close to the positive (red) battery terminal as possible. Cut about 12 inches from the ring terminal and install the fuse. Use 2 x 150 Amp fuses for the 3000W inverter
- Disconnect the NEGATIVE (-) or black battery terminal of the vehicle
- Route cables close to the battery
- For items 5 and 6, you are installing (2) cables. (2) cables are needed for the PRO 3000 Watt Inverter
- Install the insulated terminal boots on the inverter end of the power cables (RED = positive, BLACK = negative)
- Connect each BLACK Cable to the NEGATIVE (-) terminal on the Inverter
- Connect each RED Cable to the POSITIVE (+) terminal on the Inverter
- Connect the other end of the RED cable to the (+) terminal on the vehicle battery
- Visually inspect and make sure the red wire or its connectors are not touching any metal parts of the vehicle or the black wire connectors
- Connect the other end of the BLACK cable to the (-) terminal on the vehicle battery. Caution: There is normally a spark at the point of contact at the negative terminal
- Check all connections making sure the RED cables are connected to the POSITIVE (+) terminals and the BLACK cables are connected to the NEGATIVE (-) terminals
- Go to the GETTING STARTED section to review the Battery Low Voltage Alarm setting based on the vehicle the inverter will be used with
Getting Started
- Connect the Remote On/Off Controller with Fast Charge USB (Optional)
- Press the POWER button to turn on your inverter (or the POWER button on the remote controller)
- When the inverter is powered on the Input Voltage LED is green
Setting Up Your Inverter
Cobra Pro Power Inverters are equipped with (2) settings to accommodate battery run times for both large and small vehicles. From the factory, the PRO Power Inverter is set to an 11.5 Volt default Battery Low Voltage Alarm and will automatically shut down at 10.5 Volts to protect the battery from deep discharge (so you can start your vehicle). This setting is ideal for Professional Trucks. If using a Cobra PRO Power Inverter with a car, van, or RV, the Alternative Setting is recommended since batteries in these vehicles can afford a slightly deeper drain and will avoid an “early” Battery Low Voltage Alarm signal and longer run time.
CAUTION: The Default Low Voltage Alarm Setting is designed for Professional Trucks and larger vehicle batteries. If using this setting with a standard vehicle, van, or RV, the alarm will sound earlier than necessary and reduce battery run time.
Instructions For Changing Low Voltage Alarm Setting
- Connect the Remote On/Off Controller with Fast Charge to 10.5 Volts
- Press the POWER button to turn on your inverter (or the POWER button on the remote controller)
- Press and hold the POWER button for 5 seconds or until the Input Voltage
LED turns blue
- Once blue, the Battery Low Voltage Alarm will be set to sound when your battery Voltage reaches 10.5 Volts. The power inverter will automatically shut down when the battery voltage reaches 9.5 Volts to protect the battery from deep discharge (so you can start your vehicle). The setting will not change when the inverter is turned off or the battery is disconnected. To set the inverter back to the Battery Low Voltage Alarm Default Setting at 11.5 Volts, follow steps 1 and 2.
CAUTION: Your power inverter will automatically shut off at 9.5 Volts when set to the Alternate Battery Low Voltage Alarm Setting. Do not set the Battery Low Voltage Alarm Setting to the Alternate Setting when using your inverter with a Professional Truck or larger vehicle.

Note Connect the Negative and Positive Cables to the Negative and Positive Terminals on the Vehicle Battery Be Sure the Cables are not Incorrectly Connected
FAQS About Cobra PRO 3000W Professional Grade Power Inverter
What is a power inverter?
A power inverter is a device that converts DC (direct current) power from a battery or other sources into AC (alternating current) power, which is what most household appliances use.
What appliances can the Cobra PRO 3000W power?
The specific appliances that can be powered depend on the wattage and capacity of the inverter. Generally, a 3000W inverter can handle a variety of household appliances and power tools.
Can the Cobra PRO 3000W be used in a vehicle?
Many power inverters, including those of high capacity like the Cobra PRO 3000W, are designed for use in vehicles. They can be connected to a car’s battery to provide AC power on the go.
How do I install the Cobra PRO 3000W inverter?
Installation procedures may vary, but generally, it involves connecting the inverter to a power source (such as a battery), ensuring proper grounding, and connecting the AC devices to the inverter’s outlets. Always follow the manufacturer’s instructions for installation.
Does the Cobra PRO 3000W have overload protection?
Many inverters have built-in protection mechanisms, including overload protection. This feature helps prevent damage to the inverter and connected devices if the power demand exceeds the inverter’s capacity.
What is the difference between a modified sine wave and a pure sine wave inverter?
Power inverters produce either a modified sine wave or a pure sine wave. Pure sine wave inverters are generally more expensive but provide a cleaner and more stable power output, making them suitable for sensitive electronics. Modified sine wave inverters are more economical but may not be suitable for some devices.
Can I connect the Cobra PRO 3000W to solar panels?
Some inverters are designed to work with solar panels, allowing you to convert solar energy into usable AC power. Check the product specifications to see if the Cobra PRO 3000W supports solar panel connections.
How do I maintain and troubleshoot the Cobra PRO 3000W inverter?
The user manual will provide information on maintenance and troubleshooting. Regular checks on connections, ensuring proper ventilation, and understanding the LED indicators are common practices.
Can the Cobra PRO 3000W be used for extended periods, such as for powering appliances during a power outage?
The continuous usage of a power inverter depends on its design and the capacity of the connected power source (e.g., battery). It’s important to check the product specifications and user manual to determine the recommended usage duration and whether the inverter is suitable for prolonged use.
Is the Cobra PRO 3000W compatible with sensitive electronic devices like laptops and smartphones?
Power inverters with a pure sine wave output are generally recommended for sensitive electronics to ensure a clean and stable power supply. Check the inverter’s specifications to confirm if it produces a pure sine wave, making it suitable for charging and operating sensitive devices without risk of damage.
