5kW Low Frequency Pure Sine Wave Inverter


5kW Low Frequency Pure Sine Wave Inverter for Off-Grid Power – OEM & ODM AvailableThis inverter delivers reliable power for demanding environments. It’s built to handle high surge loads, protect sensitive electronics, and operate efficiently in off-grid systems. With a toroidal transformer and low-frequency design, it offers long-term durability and consistent performance.

Powerful Surge Handling

Unlike standard inverters, this model handles up to 15,000W of surge power—three times its rated capacity. That means it can easily start heavy-duty appliances such as air conditioners, refrigerators, water pumps, and power tools. For remote sites or backup systems, this surge capability ensures smooth operation from the start.

5kW Low Frequency Pure Sine Wave Inverter

Clean and Stable Output

The inverter produces pure sine wave AC power, which matches the quality of utility electricity. As a result, it protects sensitive devices like medical equipment, computers, and communication systems from voltage fluctuations and electrical noise.

Durable Low-Frequency Design

Thanks to its low-frequency architecture, the inverter reduces stress on internal components. This design extends its lifespan and improves reliability, especially in harsh or fluctuating environments. You can count on it for consistent performance over time.

Flexible Charging Options

In addition to AC charging, the inverter supports solar charging systems. This flexibility makes it ideal for off-grid homes, cabins, RVs, and mobile power setups. Whether you’re using grid power, solar panels, or both, the system adapts to your energy needs.

Built-In Safety Features

To protect your system and connected devices, the inverter includes multiple safety layers. These features guard against short circuits, overload, overheating, and reverse polarity. With these protections in place, you can operate with confidence.
