4000W Solar Power Inverter Kit 12V–110V | LCD & 30A Controller

Q: What is the actual continuous power output of this solar power inverter?

The inverter provides 300W of continuous rated power, with a peak (surge) capacity of 4000W. Always ensure the total power draw of all connected devices stays at or below 300W for safe, reliable operation.

Q: Is the solar panel weatherproof for outdoor use?

Yes. The 36W monocrystalline solar panel carries an IP65 waterproof rating, making it suitable for outdoor deployment in rain and varying weather conditions. Its operating temperature range is −20°C to +60°C.

Q: What devices can I NOT run on this inverter?

This inverter outputs a modified sine wave, which works well for resistive loads (phones, laptops, TVs, lamps, kettles, rice cookers, low-power tools). It is not recommended for laser printers, some variable-speed motors, certain medical equipment, or sensitive audio/video gear that requires a pure sine wave output.

Key Features

🔆 Intelligent LCD Display

The full-color LCD screen shows real-time battery input voltage, output voltage, battery capacity, frequency (60 Hz), and load capacity — so you always know exactly what your system is doing.

⚡ Dual USB Fast Charging

Two USB ports (up to 4.2A combined) let you charge smartphones, tablets, laptops, and other USB devices simultaneously alongside the AC outlet — no extra adapters needed.

🛡️ 8-Layer Safety Protection

Built-in protections cover: reverse polarity, low input voltage, high input voltage, over-current, short circuit, over-temperature, overload, and internal fuses — for worry-free operation in any environment.

☀️ 36W Monocrystalline Solar Panel

The high-efficiency mono panel delivers up to 36W of clean solar energy. IP65 waterproof rating makes it suitable for outdoor use in varied weather conditions. Compact at 840×420×2.5 mm and only 1.2 kg.

🔋 30A Smart Charge Controller

The PWM controller automatically detects 12V or 24V battery systems and manages charging cycles intelligently to extend battery life. Adjustable float, discharge stop, and reconnect voltages give you full control.

🚗 Compact & Portable

The inverter weighs just 0.65 kg and measures 20×11.2×5.6 cm — lightweight enough to toss in your kit bag. Works with virtually any standard 12V vehicle power socket or direct battery connection.

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 device = 12 × 60 × 0.8 × 0.9 ÷ 100 = ~5.2 hours.

Compatible With

Mobile phones, laptops, computers, tablets, TVs, digital cameras, incandescent lamps, rice cookers, electric kettles, low-power tools, and more (resistive/standard loads only; total connected load must not exceed rated 300W).

Frequently Asked Questions

Q: What is the actual continuous power output of this solar power inverter?

A: The inverter provides 300W of continuous rated power, with a peak (surge) capacity of 4000W. Always ensure the total power draw of all connected devices stays at or below 300W for safe, reliable operation.

Q: Can I use this solar kit to charge a 24V battery system?

A: The 30A charge controller automatically detects and supports both 12V and 24V battery systems. However, the inverter is designed for 12V input only. For a 24V battery setup, the charge controller will work independently, but the inverter would require a 12V battery source.

Q: Is the solar panel weatherproof for outdoor use?

A: Yes. The 36W monocrystalline solar panel carries an IP65 waterproof rating, making it suitable for outdoor deployment in rain and varying weather conditions. Its operating temperature range is −20°C to +60°C.
