Page 9: Grounding Instructions
SPECIAL NOTES FOR CHILDREN: Never allow children to operate or play with the inverter. Keep the unit away from children. Choose to install the inverter out of the reach of children. Keep all accessories out of the reach of children as they could be dangerous. -
Page 10: Load Precautions
Load Precautions Note: If you encounter any situation where certain loads cannot be used when using the inverter, please contact our after-sales email promptly, and we will do our best to solve the problem for you. The rated power consumption and maximum power consumption of the following devices vary significantly. -
Page 11: Calculation Method Of Required Capacity
Calculation Method of Required Capacity To ensure the inverter works properly, make sure that the rated voltage of the battery matches the rated input voltage of the inverter. Keep in mind that small-capacity batteries may not be enough to power large appliances. In this case, the load of the appliance may cause the inverter to enter undervoltage protection mode. - Page 12 Please refer to the formulas below to calculate your battery and inverter needs: Formula to Calculate Required Inverter Wattage: Total Load Power (W) / Inverter Efficiency = Inverter Wattage (If the sensitive equipment is included in the devises that you connected to the inverter, the starting power of it may need to be increased by 3 to 8 times depending on the different situation.
- Page 13 Simple Example Reference Example: Load: Lighting 20W + Laptop 100W + Smartphone Charging 6W + Coffee Maker 800W Runtime: 2 hours Battery voltage: 12VDC Inverter efficiency: Calculation Method: （20+100+6+800*4）/90% ≈ 3696W Inverter Power NOTE: The coffee maker belongs to electrical appliances with motor, which requires at least 4 times the starting power.
- Page 14 Example: Load: Lighting 20W + Laptop 100W + Smartphone Charging 6W + Kettle 500W Runtime: 2 hours Battery capacity: 330AH Inverter efficiency: Inverter voltage: 12VDC Calculation Method: 330*12/(（20+100+6+500） Battery Runtime /90%) ≈ 5.69H Power Consumption 12*0.64A=7.68W at No load Summary: When using a battery with a capacity of 330AH, the load can be used for around 5.69 hours, with a no-load power consumption of 7.68W.

Page 15: Product Information
Product Information The waveform output waveform of this inverter is pure sine wave, which has the same high-quality as the power provided by utility and/or domestic power sources. This type of waveform is ideal for most electrical devices, appliances, and tools. The pure sine wave output of this inverter also provides more capabilities than modified sine wave inverters because it is a cleaner form of power. -

Page 25: Operation Method
Operation Method CAUTION Before making any electrical connections, ensure that both the inverter and the connected appliance’s power switches are turned OFF. When switching off the inverter, make sure to turn off all connected electronic devices first. Even when the inverter is off, its capacitors may be charged, so to modify the circuitry or perform any maintenance work on the inverter, always ensure to disconnect both the DC and AC terminals. -
Page 26: Connection On The Cigarette Lighter Side
Connection on the cigarette lighter side Insert the cigarette lighter plug of this product into the cigarette lighter socket of the vehicle, and the power will be turned on automatically. For most typical cars, the maximum available power is about 100W to 150W. NOTE: If you use an output that exceeds the allowable range, the fuse on one side of the car may blow. - Page 27 CAUTION The battery provides DC input voltage to the inverter, and its rated voltage should match the rated input voltage of the inverter. Any voltage exceeding the inverter input voltage range may cause inverter overload or damage. In addition to voltage, the capacity of the battery (measured in amp-hours) should match the power consumption of the load.
