1. Introduction
This manual provides essential information for the safe and efficient operation of your MFUZOP Pure Sine Wave Power Inverter. This device converts DC (Direct Current) power from a battery into AC (Alternating Current) power, suitable for various electronic devices and appliances. Please read this manual thoroughly before use and retain it for future reference.
2. Safety Information
WARNING: Failure to follow these safety instructions may result in electric shock, fire, serious injury, or death.
- Ensure proper ventilation around the inverter to prevent overheating.
- Do not expose the inverter to water, rain, snow, or spray.
- Do not operate the inverter if it has been damaged in any way.
- Keep children away from the inverter.
- Connect the inverter only to a battery with the correct voltage (12V or 24V DC).
- Always connect the positive (+) terminal of the inverter to the positive (+) terminal of the battery and the negative (-) terminal of the inverter to the negative (-) terminal of the battery. Reverse polarity can cause damage.
- Avoid connecting loads that exceed the inverter's rated power.
- Do not disassemble the inverter. Refer all servicing to qualified personnel.

The MFUZOP Power Inverter includes multiple safety protections: Overheating, Low Voltage, Short-circuit, Overload, Undervoltage, and Surge protection.

3.2 Intelligent Voltage Detection System
The inverter features an intelligent system that automatically detects the connected battery voltage (12V or 24V) and adjusts its operation mode accordingly.

The inverter automatically detects 12V or 24V battery input. For 12V, it provides 1500W rated power (3000W peak). For 24V, it provides 3000W rated power (6000W peak).
4. Setup
4.1 Connecting to a Battery
- Ensure the inverter's ON/OFF switch is in the OFF position.
- Connect the red battery cable to the positive (+) terminal of the inverter and the positive (+) terminal of your 12V or 24V DC battery.
- Connect the black battery cable to the negative (-) terminal of the inverter and the negative (-) terminal of your 12V or 24V DC battery.
- Ensure all connections are tight and secure. Loose connections can cause overheating and damage.
4.2 Connecting to a Solar System (Optional)
The inverter can be integrated into a solar power system. Follow the diagram below for proper connection sequence:

5. Operating Instructions
5.1 Powering On/Off
- After securing all connections, switch the inverter's ON/OFF button to the ON position.
- The LCD display will illuminate, showing the current input voltage, output power, and frequency.
- Connect your AC appliances to the AC outlets and USB/Type-C devices to their respective ports.
- To turn off the inverter, disconnect all loads, then switch the ON/OFF button to the OFF position.
5.2 Understanding the LCD Display
The LCD display provides real-time information about the inverter's status:
- Input Voltage (DC V): Displays the current voltage of the connected battery.
- Output Power (W): Shows the current power consumption of connected AC loads.
- Output Frequency (Hz): Indicates the AC output frequency (typically 50Hz).
- Battery Level Indicator: Provides an approximate visual representation of the battery's charge level.
5.3 Application Examples
The MFUZOP Power Inverter is suitable for a wide range of applications, both indoors and outdoors, providing clean and stable power for your devices.

Indoor applications include powering laptops, projectors, coffee machines, and kitchen appliances.

Outdoor applications include powering tools like chainsaws and electric drills, as well as camping equipment.
6. Maintenance
- Cleaning: Regularly clean the exterior of the inverter with a dry, soft cloth. Do not use liquids or abrasive cleaners.
- Ventilation: Ensure the cooling fan and ventilation openings are free from dust and obstructions. Blocked vents can lead to overheating.
- Connections: Periodically check battery cable connections for tightness. Loose connections can cause voltage drops and heat buildup.
- Storage: When not in use for extended periods, store the inverter in a cool, dry place, away from direct sunlight and moisture.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output | Inverter switch is OFF Low battery voltage Loose battery connections | Turn switch ON Recharge or replace battery Tighten connections |
| Overload alarm | Connected load exceeds inverter capacity | Reduce load by disconnecting some appliances |
| Overheat alarm | Poor ventilation Excessive ambient temperature Prolonged high load operation | Ensure clear airflow around inverter Move to a cooler environment Reduce load or allow inverter to cool down |
| Low voltage alarm | Battery voltage is too low | Recharge the battery immediately |
| Short-circuit protection | Short circuit in output wiring or connected appliance | Identify and resolve the short circuit. Disconnect faulty appliance. |
