⚠️ Important Usage Notes

• This is a modified sine wave inverter — NOT suitable for motor-driven appliances (hair dryers, air conditioners, refrigerators, microwave ovens, water pumps, induction cookers, coffee machines).
• Total rated load of connected devices must be ≤ 300W.
• When using the cigarette lighter cable, keep output under 150W. For loads over 150W, connect using the included battery crocodile clips.
• For DC 12V vehicle use only — not compatible with DC 24V systems or aircraft.
• Always connect to the battery before switching the inverter on.
• Keep the inverter dry, in a cool environment (0°C–40°C), and away from direct sunlight and heat sources.

Battery Runtime Estimate

Use this formula to estimate how long your battery will last:

Working Time (hours) = Battery Capacity (Ah) × Battery Voltage (V) × 0.8 × 0.9 ÷ Load Power (W)

Example: A 12V / 60Ah battery powering a 100W load: 12 × 60 × 0.8 × 0.9 ÷ 100 = ~5.2 hours

Frequently Asked Questions

Q: What is the difference between peak power (4000W) and rated power (300W) on this solar inverter kit?

A: The rated power (300W) is the continuous load the inverter can safely handle for extended periods. The peak power (4000W) refers to the brief surge capacity needed when certain devices start up. For everyday use, ensure all connected appliances total 300W or less in rated power consumption.

Q: Can I use this solar inverter kit to run a refrigerator or air conditioner?

A: No. This is a modified sine wave inverter, which is not compatible with motor-driven or compressor-based appliances such as refrigerators, air conditioners, microwave ovens, or water pumps. It is best suited for electronics, LED lighting, laptops, smartphones, and similar loads under 300W.

Q: How do I connect the 50W solar panel, charge controller, and inverter together?

A: Connect the 50W solar panel's DC output to the solar input terminals of the 50A charge controller. Then connect the controller's battery terminals to your 12V battery. Finally, connect the power inverter's battery clips or cigarette lighter plug to the 12V battery. The controller will regulate charging automatically and protect the battery from over- and under-charge.

Q: Is this kit suitable for camping and off-grid emergency use?

A: Yes — the kit is designed for exactly these scenarios. The lightweight 50W solar panel (0.8 kg) gathers solar energy during the day to charge a 12V battery via the 50A controller, which you can then draw on through the inverter for AC power or USB charging at any time, making it ideal for camping trips, road travel, or emergency preparedness.
