TVNIKD 3500W 12V Power Inverter Instruction Manual

Introduction

This manual provides essential safety and operating instructions for your TVNIKD 3500W Power Inverter. Please read and understand these instructions carefully before use to ensure safe and effective operation of your device. This inverter converts 12V DC power from your vehicle's battery to 110V AC household power, suitable for various applications including vehicles, RVs, trucks, and off-grid solar setups.

Important Safety Instructions

• Always ensure the inverter is turned OFF before maintenance or cleaning. Turning off controls will not reduce this risk.
• Do not place the inverter on a flat surface.
• Avoid placing the inverter near heating vents, radiators, or other sources of heat or flammable materials.
• Do not place the inverter in direct sunlight. The ideal air temperature for operation is between 50°F and 80°F (10°C and 27°C).
• Only connect the power inverter to a 12V battery or power supply. Do not attempt to connect the inverter to any other power source, including an AC power source. Connecting to a 6V or 16V battery will cause damage to the inverter.
• Do not use the inverter with a product that draws a higher wattage than the inverter can provide, as this may cause damage to the inverter and product.
• Keep out of reach of children.
• Do not expose the inverter to rain or snow.
• Use of an attachment not recommended or sold by the unit manufacturer may result in a risk of fire, electric shock, or injury to persons.
• Do not disassemble the unit, as there are no user-serviceable parts. All servicing should be performed by qualified service personnel.
• Store inside, in a cool, dry place, out of the reach of children.
• Recycle or properly dispose of internal electrical components.

Product Features

• Continuous Power Output: Provides 3500W continuous modified sine wave power, with a peak output of 7000W.
• AC Outlets: Equipped with 4 standard 120V AC outlets (60Hz).
• USB Ports: Includes 2 USB ports (5V, 2.0A) for charging mobile devices.
• LCD Display: An updated LCD screen indicates real-time battery status, helping to monitor voltage drops.
• Cooling System: Features 3 powerful built-in fans for fast heat dissipation. The smart cooling system activates when the device gets warmer or output power exceeds a certain threshold, and slows down when the temperature decreases, ensuring quiet operation most of the time.
• Safety Protections: Built-in 8x40A fuses provide protection against short circuit current. The grounding wire protects against electric shock. Stable charging technology protects against overheating, undervoltage, overvoltage, overloads, and overcharging.
• Pure Copper Wires: Comes with 2 x 3.5FT 4AWG pure copper wires, which carry more current and reduce heat generation for enhanced protection.

Setup

Connecting Inverter Cables to the Inverter

1. Locate the Positive (RED) and Negative (BLACK) terminals on the inverter.
2. From the Positive (RED) and the Negative (BLACK) terminals, remove the nut, split lock, and flat washer.
3. Place the Positive (RED) ring connector onto the Positive (RED) inverter terminal. Place the Negative (BLACK) ring connector onto the Negative (BLACK) inverter terminal.
4. Place a flat washer and split lock on top of each ring connector. Put a nut over these and tighten.
5. NOTE: Please use the cables we provided. DO NOT use battery clamps.

Grounding the Inverter

1. Turn off and disconnect the inverter.
2. Locate the chassis ground screw on the back of the inverter.
3. Remove the outer nut and loosen the first locking washer.
4. Attach the grounding wire's ring connector to the ground terminal of the inverter.
5. Tighten the locking washer securely. Then, replace the outer nut and tighten it securely.
6. Attach the other end of the wire to a properly grounded location.
7. Vehicle: Connect to the chassis, unpainted frame part, or engine block of the vehicle.
8. Fixed location: Connect to a ground rod or other appropriately sized ground.

Operating Instructions

1. Connect the inverter (see Connecting Inverter Cables section).
2. Switch the inverter's ON/OFF switch to the ON (I) position.
3. The GREEN LED indicator will light, indicating the inverter is receiving power.
4. Plug the device into the inverter's AC outlet.
5. Make sure the device to be operated is turned OFF before plugging it in.
6. Switch the inverter's ON/OFF switch to the OFF (0) position to turn off.
7. To disconnect, reverse the above procedure.
8. "beep": This sound is normal during operation.

Power Source

Your average automobile battery at full charge will provide an ample power supply to the inverter when the engine is on. Keep the car running at all times when using the inverter. The actual length of time the inverter will function depends on the age and condition of the battery and the power demand being placed by the device being operated with the inverter. When possible, recharge your batteries when they are not more than 50% discharged. This gives the batteries a much longer life cycle than recharging when they are more deeply discharged.

LED Indicator and Shutdown Protection

The Green LED lights automatically when the inverter is plugged into a 12 volt DC power source and is turned on. The Red LED lights, the alarm sounds, and the inverter automatically turns itself off under the following conditions:

• When the power input from the vehicle's battery drops to approximately 10.5 volts, the low voltage alarm will sound. When the voltage goes down below 10 VDC, the inverter shuts off. Recharge or replace the battery.
• When the power input from the vehicle's battery exceeds 16 volts, high voltage protection occurs.
• The continuous load demand from the equipment or device being operated exceeds the continuous load rating of the inverter. Use a higher capacity inverter or lower rated device.
• The thermal resistor exceeds 80°C (176°F). Allow the inverter to cool. Do not block the cooling slots or air flow over and through the inverter. Reduce the load on the inverter to the continuous rated output.
• RESET: To reset after shutdown occurs, switch the inverter's ON/OFF switch to the OFF (0) position. Check the source of the problem and correct. Switch the inverter's ON/OFF switch to the ON (I) position.

Maintenance and Storage Instructions

1. Before each use, ensure that all of the inverter's components are in place and in good working condition.
2. After use and before performing maintenance, unplug and disconnect the inverter.
3. Use a clean, dry cloth to wipe external surfaces of the inverter's case.
4. Servicing does not require opening the unit, as there are no user-serviceable parts. All servicing should be performed by qualified service personnel.
5. Store inside, in a cool, dry place, out of the reach of children.
6. Recycle or properly dispose of internal electrical components.
