The 150W DC-AC Power Inverter Board is a compact, efficient power converter designed to transform DC 24V battery power into AC 220V output, making it suitable for powering small electronic devices, lighting, and chargers from a 24V battery source. This version includes built-in overload protection, providing a safer and more reliable solution than unprotected inverter modules.
At the heart of the board is a high-frequency inverter circuit that steps up the 24V DC input to approximately 220V AC output. The module is designed for battery-powered applications where a reliable AC source is needed, such as camping, emergency backup, and portable power stations. The overload protection circuit automatically limits or shuts down the output if the load exceeds the rated capacity, protecting both the inverter and connected devices.
The board features screw terminals for secure input and output connections, and the compact PCB design with mounting holes makes it easy to integrate into custom enclosures and portable power systems. The DC 24V input is compatible with common battery configurations, including two 12V batteries in series or a dedicated 24V battery pack.
The 220V AC output is suitable for powering low-power devices such as:
-
LED lighting
-
Phone and tablet chargers
-
Small power adapters
-
Laptop chargers (with appropriate power rating)
-
Small electronic equipment
Important Technical Note: This inverter board produces a modified sine wave or square wave output, depending on the specific design. It is not suitable for all devices — particularly those with sensitive electronics or inductive loads such as motors and compressors. Always check the compatibility of your device before connecting. For devices with motors or sensitive electronics, a pure sine wave inverter is recommended.
Overload protection is a key feature of this board. When the load exceeds the rated 150W capacity, the protection circuit activates to prevent damage. Some versions include automatic recovery — the inverter resumes operation once the overload condition is removed.
Whether you are building a portable power station, setting up an emergency backup system, or powering equipment from a 24V battery bank, the 150W DC-AC Power Inverter Board provides a practical, protected solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.
