Explore Modified Sine Wave Power Inverters
The current DAMAVO modified sine wave inverter range is built around the YM1466 series, with different configurations for input voltage, AC output voltage, and socket standards. Whether your application requires 110V or 220V AC output, the series provides a compact way to add AC power to 12V or 24V DC electrical systems.
01
Modified Sine Wave Inverter YM1466
The YM1466 110V version is designed for applications using a 12V or 24V DC power system and requiring 110V AC power.
-
Flexible 12V / 24V Input Options
- The YM1466 is available for both 12V and 24V DC systems, making it easier to match different vehicle and equipment electrical systems. Choose the input voltage that matches your existing DC power system.
-
110V / 220V Output with Multiple Socket Standards
- The series provides 110V and 220V AC output options, while the 220V version is available with European, British, and Chinese socket standards. This makes the YM1466 easier to configure for different markets and product platforms. -
AC Power Plus USB Charging
- In addition to 100W AC output, the YM1466 provides USB-A QC 18W and USB-C outputs up to 12V 3A. This allows one compact inverter to support suitable low-power AC devices and compatible USB-powered electronics. -
Compact Design for Space-Limited Applications
- With a compact housing and convection cooling vent design, the YM1466 is designed for applications where installation space is limited. Its ABS + PC 94-V0 housing also provides a flame-retardant material solution for vehicle and equipment applications.

What is a modified sine wave inverter?
A modified sine wave inverter converts DC power from a battery or electrical system into AC power. It provides a practical AC power solution for many basic electrical loads where a pure sine wave output is not required.
For vehicle and equipment applications, the right choice depends on the type of equipment being powered, its power requirements, and the manufacturer's recommended waveform.
02/
What is a modified sine wave inverter used for?
Modified sine wave inverters are commonly considered for applications that need AC power from a battery or DC electrical system but do not require the output characteristics of a pure sine wave inverter.
Typical applications can include selected vehicle accessories, commercial vehicles, agricultural equipment, material handling equipment, and portable power applications.
Typical applications can include selected vehicle accessories, commercial vehicles, agricultural equipment, material handling equipment, and portable power applications.
The connected equipment should always be checked before selecting an inverter, especially when motors, sensitive electronics, or other demanding loads are involved.
03/
What is the difference between a modified sine wave inverter and a pure sine wave inverter?
The main difference is the AC output waveform.
A modified sine wave inverter produces a stepped waveform, while a pure sine wave inverter produces a smoother waveform that more closely matches utility power.
Modified sine wave inverters can be a practical choice for suitable lower-complexity loads, while pure sine wave inverters are generally preferred when the equipment requires cleaner AC power or has more sensitive electrical characteristics.
If you are unsure which type is suitable, check the equipment manufacturer's requirements or contact DAMAVO with your application details.

When should I choose a modified sine wave inverter?
A modified sine wave inverter may be appropriate when:
The connected equipment is compatible with modified sine wave power.
The application requires AC power from a 12V, 24V, or other DC power system.
The equipment does not require a pure sine wave output.
A compact and practical AC power solution is more important than supporting sensitive or complex loads.
The decision should be based on the actual electrical requirements of the equipment rather than price or power rating alone.

How do I choose the right modified sine wave inverter?
Start with the requirements of the application rather than the inverter model.
Check these key points:
Check these key points:
DC input voltage — such as 12V or 24V.
Required AC output voltage — such as 110V or 220V.
Continuous power requirement — the inverter should provide enough continuous power for the connected load.
Startup or surge requirement — some equipment requires additional power when starting.
Waveform requirement — confirm whether the equipment can operate with modified sine wave power.
Installation and environmental conditions — consider available space, ventilation, temperature, moisture, and other operating conditions.
If these requirements are clear, it becomes much easier to identify a suitable inverter configuration.
