• Ventilation: Maintain distance from objects to avoid blocking vents.
• Clean: Avoid dusty environments or particles that could enter the fan.
• Safety: Keep away from flammable objects (gasoline, alcohol) due to potential sparks from connections.

2. Assemble the inverter:

Due to its weight, mount on a solid platform (floor, table, bracket) capable of supporting its capacity. Secure with four screws.

Note: If not connected to the remote box, the product can function as a normal modified sine wave inverter.

5. USING TIME OF BATTERY

1. Current and voltage:

The battery must match the inverter's rated input voltage. Insufficient battery capacity may lead to excessive current draw and voltage drop, triggering undervoltage protection. The formula for battery current is: Load Power / Battery Voltage. Add approximately 10% for inverter loss. Example: 400W load, 12VDC battery: (400W / 12V) * 1.10 = 37A.

2. Battery working time:

Calculated as: Time (hours) = Battery Capacity (AH) × Battery Voltage (V) × Efficiency Rate / Load Power (W). Example: 200AH battery, 400W load, 90% efficiency: (200 AH * 12V * 0.90) / 400W = 5.4 hours.

Notice: Nominal battery capacity is based on a 20-hour discharge rate. Higher discharge currents reduce capacity and working time. Consult battery manufacturer specifications. Battery charge level also affects performance.

6. CONNECTION

1. Grounding:

Connect the "Grounding" terminal on the back panel to a ground source (vehicle chassis, ship grounding system, or earth). This is crucial for safety. Use a minimum 14AWG wire. Failure to ground can result in electric shock. ⚡

2. Connect to the battery:

Ensure battery voltage matches inverter requirements. Use appropriately sized DC input wires to prevent voltage drop under heavy loads. Refer to the wire gauge table.

Notice: The table is a guideline. Two thinner wires can be used in parallel if their total cross-sectional area meets the requirement. For high current, minimize lead length (under 1m) to reduce voltage drop.

Connect the battery's cathode to the inverter's black terminal and the anode to the red terminal. Secure connections.

Warnings:

• Wear eye protection and protective clothing when working with batteries.
• Have water and soap ready for acid spills. Seek medical attention for eye contact.
• Keep flammable materials away from installation area due to potential sparks.
• Ensure good ventilation. Batteries can release flammable gas.
• Secure DC input wires to prevent voltage drop or overheating.
• Incorrect polarity or short circuits can damage the inverter. ⚡
• Remove metal jewelry (rings, watches) during installation to prevent short circuits.
• High input voltage can damage the inverter, even with over-voltage protection.

3. Connection of the AC appliance

Plug the appliance directly into the inverter's AC output socket. Ensure both the appliance and inverter switches are OFF before connecting.

Warnings:

• Ensure inverter and appliance switches are OFF before connection.
• Check power cords for damage; replace if necessary.

4. Assemble the remote control box

Mount the remote control box using the provided holes and screws. Connect the remote control cable between the box and the inverter.

7. USAGE OF INVERTER

1. How to use a inverter:

1. Verify battery voltage and capacity match inverter requirements.
2. Connect the battery to the inverter's DC cable, ensuring correct polarity and secure contact.
3. Press and hold the inverter or remote switch for over 0.5 seconds. If the indicator light turns on, the inverter is operating normally. This prevents accidental activation.
4. Turn off appliances and unplug them from the inverter's AC output socket before switching off the inverter.
5. Cooling fans activate when the internal temperature reaches approximately 40°C.
6. Switch off both the inverter and remote to stop operation. Indicator lights will turn off. The inverter consumes no battery power when switched off.

2. How to use USB outlet:

The USB outlet provides a stable 5V DC voltage with a maximum current of 1000mA (or 2100mA, depending on model). It can power portable USB devices.

Notice: Ensure the device is USB-chargeable and its maximum working current does not exceed the outlet's rating.

8. OPERATIONAL PRINCIPLE

The inverter converts DC to AC in two steps: first, it boosts low voltage DC to high voltage DC, then uses a full-bridge converter to change high voltage DC to AC. This process utilizes advanced power devices and high-frequency power conversion technology, resulting in smaller size, lighter weight, and higher efficiency compared to traditional power frequency transformer inverters.

Diagram Description: The process involves DC input, an internal fuse, a DC step-up circuit, a DC to AC conversion circuit, and finally the AC output socket.

9. OUTPUT VOLTAGE AND WAVE FORM:

The output waveform is Pure Sine Wave, closely resembling utility-supplied AC power. It is suitable for a wide range of loads, including linear adapters, switching power supplies, transformers, and motors.

Compared to Modified Sine Wave, Pure Sine Wave improves power factor, battery usage efficiency, and reduces operating noise for inductive loads like refrigerators and electric fans. For sensitive electronics like laptop adapters, it lowers inrush current, increasing reliability and product lifespan.

Visual Description: A graph shows a smooth, sinusoidal AC output waveform.

10. ABOUT SOFT START TECHNOLOGY

This inverter features advanced soft start technology, gradually increasing output voltage from low to normal upon activation. This reduces high startup currents, making it easier to power large inductive loads.

For large inductive or capacitive loads (e.g., electric tools), it is recommended to turn on the appliance switch first, then the inverter, to allow the soft start to manage the initial surge.

11. LED DISPLAY:

The LED display shows input voltage and output protection status:

• Input(V) LED: Displays input voltage.
• Output(KW) LED: Displays output power in kW.
• Output(W) LED: Displays output power in W.
• LO: Indicates under-voltage protection status.
• HI: Indicates over-voltage protection status.
• OL: Indicates output overload or short-circuit protection status.
• OH: Indicates overheat protection status.

12. PROTECTION FEATURES:

1. Input under-voltage alarm: Buzzer sounds intermittently when input DC voltage drops below 10.1V (20.2V for 24V models), indicating impending under-voltage protection. Save data if using a computer.
2. Under voltage protection: Shuts down automatically when input DC voltage falls below 9.8V (19.6V for 24V models). Buzzer sounds continuously, green light off, red light on. Turn off and recharge the battery.
3. Over voltage protection: Shuts down automatically when input DC voltage exceeds 16V (32V for 24V models). Buzzer sounds continuously, green light off, red light on. Turn off and adjust input voltage.
