Installation and Usage Instructions

1. Prepare Tools (for 3000W 12VDC inverter)

• Battery: 300AH 12V (recommended to use a battery of not less than 400A)
• Cables: 2 Sets of 6AWG Cables (provided by the manufacturer)

2. Installation Steps

1. Confirm the positive and negative poles of the battery, install the cables and tighten the screws.

   Visual Description: Two images show the battery terminals. The left image highlights the positive (+) and negative (-) terminals on the battery with red and black markings respectively. The right image shows two sets of 6AWG cables being connected to the battery terminals, with red cables for positive and black for negative.

2. Find the positive and negative poles of the inverter input terminals, install the cables and tighten them. Red: positive, black: negative.

   Visual Description: An image of the inverter's input terminals shows where to connect the cables. The positive terminal is marked with a red '+' symbol, and the negative terminal is marked with a black '-' symbol. The connection components include a flat washer, cable, and nut.

3. Use a multimeter to confirm the inverter input voltage. Make sure the voltage reaches about 12V before turning on the inverter.

   Visual Description: An image shows a multimeter connected to the inverter's input terminals. The multimeter displays a voltage reading of 12.26V, indicating the input voltage is within the acceptable range.

4. After turning on the inverter, confirm whether the LED display normally displays the input and output voltages.

   Visual Description: Two images show the inverter's LED display. The left image shows the display indicating an input voltage of 12.32V. The right image shows the display indicating an output voltage of 110V.

3. Notes:

• Please make sure your battery is fully charged to prevent the voltage from being too low and the inverter cannot be turned on.
• Please pay attention to the positive and negative poles of the battery and the inverter; do not connect them in reverse.
• Please tighten the screws to prevent the current from being unstable.
• Please pay attention to the specification of the cable; it is recommended to use the cable provided by the manufacturer. There is a voltage drop between the battery and the inverter, and the thinner and longer the cable gauge, the greater the voltage drop.
• The installation demonstration does not add load appliances but directly measures the output voltage with a multimeter. When operating, please turn on the inverter after installing the load.
• For your appliances, please know that loads are divided into resistive and inductive loads. If you need the inverter to run resistive loads (like laptop, TV, electric cooker, LED light), please choose the inverter with continuous power higher than the appliance's rated power. It is best to use 80% of the rated power. If you use appliances with motors or compressors, such as microwaves, water pumps, or air conditioners, please choose an inverter whose continuous power is 3-7 times higher than your appliance's. If you want to power up a refrigerator, it is suggested to use a 10 times higher power inverter.
• If you want to install a fuse or breaker between the battery and inverter, generally, a 500Amp fuse is recommended for the 5000watt 12volt DC version.
• There is a screw on the bottom of the inverter for grounding. The yellow wire on the terminal is connected to the ground screw on the bottom. As long as one of them is grounded, the inverter will be grounded.
