This low frequency off-grid inverter is designed to handle capacitive, inductive, and nonlinear mixed loads, offering superior load capacity and perfect protection functions such as overload, short circuit, low/over voltage, and improper operation, without causing mechanical failures. This inverter is ideal for use in solar power systems, wind power generation systems, and wind and solar hybrid generation systems. The inverter can supply AC power to various electrical equipment including air conditioners, electric motors, refrigerators, fluorescent lights, televisions, electric fans, and other industrial power supplies.

• The pure sine wave inverter features the sixth generation efficient IPM (Intelligent Power Module) from Japanese Mitsubishi, renowned for its high efficiency and stable performance. It is equipped with robust protection functions, including safeguards against short circuits, overloads, and over-temperature conditions, ensuring a service life of up to 15 years or more.
• Intelligent, modularized, with a simple structure for easy maintenance.
• Two start modes are available: Reduction Voltage Start and Variable Frequency Start. Customers can select the start mode based on their load type, offering convenience and reducing the frequency converter's usage. This not only cuts down on equipment investment costs but also simplifies wiring and control processes.
• The output frequency can be setting via LCD panel, very convenient for customer.
• The output voltage can be set between -40 % to 20 % of rated voltage.
• The DC input voltage range is customizable, allowing users to set the over-voltage point, under-voltage point, over-voltage recovery point, and under-voltage recovery point via the LCD panel.
• This inverter produces a pure sine wave output with excellent dynamic response of less than 50ms, minimal waveform distortion, high conversion efficiency, and stable output voltage.
• Pure sine wave inverter features a built-in low-frequency isolation transformer, providing strong impact resistance and compatibility with high-impact equipment such as motors, pumps, and air conditioners. The DC busbar and AC busbar are fully isolated to prevent interference.
• The wide input voltage can be customized to meet customer requirements, with selectable ranges such as 100-400V, 200-500V, 300-600V, or 450-850V. This flexibility is ideal for solar systems without backup batteries, enabling significant cost savings and maximizing the utilization of solar energy.
• Pure sine wave inverter utilizes SVPWM (Space Vector Pulse Width Modulation) algorithms for high conversion efficiency, delivering high instantaneous power and minimal losses with efficiency reaching up to 93%.
• Pure sine wave inverter features a comprehensive data display function with an LCD screen showing various parameters including DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, and fault code display.
