3000VA Power Inverter Charger DC12V to AC220V Modified Sine Wave Inverter for Emergency Backup Power

The SDA-D3000A is a stable modified sine wave inverter with outstanding cost performance. It converts DC 12V battery energy into consistent AC 220V power for home devices and off-grid loads. Featuring MCU power-saving control and a soft-start circuit, it effectively eases the surge caused when loads start. It is well-suited for household emergency backup power and outdoor power supply scenarios.

1. Modified sine wave output ensures steady operation and is compatible with many kinds of daily household electric appliances.
2. Fitted with an aerospace-standard silent cooling fan, featuring low running noise and low idle power draw.
3. Adopts a smart MCU control solution to optimize energy conversion efficiency.
4. Comes with an auto power-on function for easy unattended operation.
5. Clear digital LED screen keeps showing output power and battery SOC in real time.
6. Low voltage protection: buzzer reminder plus automatic shutdown with indicator light; restart by toggling the power switch.
7. Overload and short-circuit protection: output power cuts off automatically with a warning alert; reset via power switch after troubleshooting.
8. Over-temperature safeguard: the inverter shuts down automatically when internal temperature exceeds the safe threshold.
9. Built-in anti-interference structure, complete protection circuits, and soft-start circuit for simple, user-friendly operation.
10. Soft-start design: output voltage rises gradually at startup to avoid sudden crashes; it suppresses instantaneous load surge and recovers quickly after voltage dip.
11. Onboard DC 5V 1A USB jack for charging small portable digital gadgets.
