Power Inverter 4000W Features

Built-in Toroidal transformer

It has high efficiency due to its design, resulting in less energy loss during the power conversion process. The closed magnetic circuit of toroidal transformers helps minimize electromagnetic interference, leading to cleaner power output.

Wide input voltage range (110V-300V)

The inverter can handle a wide range of input voltages, allowing it to adapt to different power sources.

Multiple Protection Features

Safety is paramount, which is why our inverter comes equipped with multiple protection features. From overload protection to over-temperature shutdown, your devices and the inverter itself are safeguarded against potential damage.

Well unattended function

In the event of a power outage, the inverter automatically switches to battery power until it detects low voltage, and then it safely shuts down. Once the main power is restored, it seamlessly switches back to AC power while simultaneously charging the battery. No manual intervention is required.

Auto restart while AC is recovering

After a power interruption, the inverter automatically restarts when the AC power supply is stable again.

Boost and buck AVR for voltage stabilization

It employs an Automatic Voltage Regulator (AVR) to stabilize output voltage, safeguarding connected devices from voltage fluctuations.

Cold start function

The inverter can start without AC power, the main power is unavailable.

LCD panel for comprehensive display

The LCD screen provides clear and comprehensive information about the inverter’s status and settings.

Adjustable charging voltage and charging current

Users have the flexibility to select different charging voltages (ranging from 13.0V to 14.5V) and charging currents (ranging from 0A to 30A) to suit various battery types and ensure optimal battery life.

Versatile Applications

Whether you’re powering your RV, boat, cabin, or backup power system, our inverter fits a wide range of applications. Enjoy the convenience of reliable power wherever you go.

Advantages of DC to AC Power Inverter


Pure sine wave inverters are compatible with a wide range of devices, including sensitive electronics like laptops, smartphones, and medical equipment.
Efficiency: They offer high efficiency in converting DC to AC power, minimizing energy wastage.

Reduced Electromagnetic Interference (EMI)

Pure sine wave inverters produce minimal EMI, making them suitable for use in radio and communication equipment.

Motor Operation

Appliances with motors, such as refrigerators and fans, run more efficiently and quietly with pure sine wave power.

Improved Performance

Devices powered by pure sine wave inverters tend to perform better and have longer lifespans compared to those powered by modified sine wave or square wave inverters.
