Congsin Modified Sine Wave Inverters for Sale
Reliable Modified Sine Wave Inverters by Congsin
Congsin modified sine wave inverters deliver cost-effective DC→AC power conversion for vehicles, RVs, boats, solar systems and light off-grid applications. Designed for everyday appliances such as lights, fans, power tools and small kitchen devices, these inverters balance performance and affordability without complicating installation or operation.
Key Benefits
- Affordable and efficient: Lower cost than pure sine inverters while providing stable power for most resistive and inductive loads.
- Compact and portable: Lightweight housing and simple mounting for vehicles, camping and portable power stations.
- Built-in protections: Overload, short-circuit, over-temperature and low-voltage shutdowns safeguard your devices and battery.
- Easy to use: Clear LED indicators and straightforward wiring make setup fast—even for non-technical users.
Who It’s For
Ideal for users looking for dependable, budget-friendly AC power: RV and camper owners, vehicle technicians, field workers, DIY solar installers and anyone needing backup or portable power for basic appliances.
Features That Stand Out
- Wide input range for 12V/24V systems—works with most car and solar battery setups.
- Reliable cooling and durable construction for long-term use in mobile and outdoor environments.
- Multiple output sockets and USB options available on select models for added convenience.
- Quality assurance: manufactured on automated lines, ISO9001-managed, and compliant with CE, EMC, LVD, RoHS and other international standards.
Note on Compatibility
Modified sine wave inverters are perfect for many devices but may not be ideal for highly sensitive electronics, some medical equipment, or certain motor-driven appliances that require a pure sine waveform. For sensitive loads, consider our pure sine models.

FAQ
Which country’s voltage standards does it support?
It defaults to AC 220V output, suitable for regions with 220V voltage standards such as China and Europe; it can also be customized to output AC 110V, suitable for regions with 110V voltage standards such as the United States and Japan.
Can this inverter power a laptop?
If the laptop power is within 150W and the input is AC220V, it can supply power normally.
Does it only support DC12V input voltage?
The regular model has DC12V input, and other input voltages such as DC24V can be customized. Please consult customer service for details.
Is the dual input automatically recognized or manually switched?
Automatically recognize DC12V/24V input, no manual switching required.
