DC-AC 40W Boost Inverter Module (12V to 220V AC)

The 12V to 220V High-Frequency Inverter Module (40W) is a compact DC-to-AC power conversion board designed for low-power household and DIY applications. It converts 8V–13V DC battery input into 220V AC high-frequency output, making it suitable for powering small AC loads such as LED bulbs, chargers, and energy-saving lamps.

This inverter uses a high-frequency switching design, allowing for a smaller size and lightweight construction compared to traditional transformers. The modular design also allows multiple boards to be connected in parallel to increase total output power for larger applications.

Features:

• DC to AC Conversion: Converts 8V–13V DC battery power to 220V AC
• 40W Output per Module: Suitable for low-power AC loads
• High-Frequency Inverter Design: Compact size with stable output
• Modular & Expandable: Multiple modules can be connected in parallel for higher wattage
• Lightweight & Compact: Ideal for portable and embedded projects
• DIY-Friendly: Suitable for learning, experimentation, and small inverter builds

Specification:

• Input Voltage: DC 8V–13V (12V recommended)
• Output Voltage: AC 220V (high-frequency, non-pure sine)
• Rated Output Power: Up to 40W per module
• Parallel Expansion: Supports higher output power when multiple boards are connected
• Inverter Type: High-frequency switching inverter
• Assembly: Manual soldering required (no pre-attached wires)

Output Power Reference (Typical):

• 8V input: ~1W – 10W
• 10V input: ~1W – 15W
• 12V input: ~1W – 26W (typical), higher under optimal conditions
• 14V input (max): ~1W – 35W
  ⚠ Output power depends on load type, input voltage stability, cooling, and wiring quality.

Wiring & Output Notes
A + B terminals:

• 220V AC output
• Recommended load: 1W – 15W (overload protection active)

A + C terminals:

• 220V AC output
• Supports higher loads up to 40W
• Some loads may be incompatible

Parallel Mode:

• Multiple modules can be connected for higher output (up to ~200W total with sufficient modules and cooling)

Applications:

• Power backup for LED lamps, routers, modems, and phone chargers
• Portable AC power for camping and outdoor use
• DIY solar inverter and battery projects
• Learning and experimentation with inverter circuits
• Small household electronics (not for high-power appliances)

Important Notes:

• This is a high-frequency AC output, not pure sine wave
• Standard multimeters may show incorrect voltage readings
• Use a high-frequency AC meter or test with a known load
• Not suitable for motors, refrigerators, irons, heaters, or inductive loads
• Do not exceed rated power or input voltage
• Proper heat dissipation is required for higher loads
• Manual wiring and soldering are required
