Powerful output: Convert power of DC 12V/24V/36V/48V to AC 110V/220V 60Hz. Provides continuous 400W modified sine wave power and 800W peak power.
Multi-protection: safe charging design provides protection against, over-temperature, low voltage, over voltage charging, short-circuiting, and overloads.
Top quality material: this inverter board is made of high-quality material, which is durable and has a long service life.
Electrical appliances: non-inductive household appliances, lamps, soldering irons, set-top boxes, chargers, etc.
This 400W inverter board is ideal for powering resistive loads and simple electronics. Here’s what you can run:
💡 LED lamps and lighting – Perfect for off-grid lighting setups
🔌 Phone and laptop chargers – Keep devices powered anywhere
🛠️ Soldering irons – Great for DIY electronics work
📺 Set-top boxes and small TVs – Entertainment during outages
🔋 Battery chargers – Charge tool batteries or power banks
DIY enthusiasts – Build your own portable power station or solar backup system
Off-grid users – Small cabins, camping setups, or van conversions
Repair technicians – Replace faulty inverter boards in existing equipment
OEM/ODM buyers – Integrate into your own product designs
Modified sine wave inverters are cost-effective and work well for simple devices like lights, chargers, and motors. However, sensitive electronics (medical devices, variable-speed tools, high-end audio) perform better with pure sine wave inverters. If your application involves only resistive loads, this 400W modified sine wave board is an excellent choice.
What input voltage should I choose?
Select based on your battery bank. Common choices: 12V for cars/RVs, 24V for small solar systems, 48V for higher efficiency setups.
Can this board run a refrigerator?
No. Refrigerators require higher starting power and are best served by a larger pure sine wave inverter.
Is installation difficult?
Basic soldering and wiring knowledge is recommended. Ensure correct polarity and adequate wire gauge for safe operation.
