Import 400kw Off Grid Solar Inverter Ac480v 3 Phase — Buy in wholesale FOB from Supplier in China

This 400kW off-grid solar inverter converts DC power from solar panels or batteries into stable AC480V three-phase power, using SVPWM (Space Vector Pulse Width Modulation) technology for high conversion efficiency up to 94%. The SDP series pure sine wave inverter is designed for areas without grid electricity, delivering clean power suitable for capacitive, inductive, and nonlinear mixed loads. Its modular design incorporates the sixth-generation IPM module from Mitsubishi and a DSP28335 chip from Texas Instruments, ensuring rapid response, stable performance, and long service life.

The inverter supports a wide DC input voltage range, configurable between 100-300V, 200-500V, or 500-850V, making it adaptable to solar systems with or without backup batteries. Output voltage can be adjusted between -40% to +20% of the rated voltage with ±1% accuracy, and the system offers two start modes: Reduction Voltage Start and Variable Frequency Start. Safety features include electrical isolation via a transformer, circuit breakers on input and output, and comprehensive protection against overload, short circuits, and low or over battery voltage.

Typical applications include powering industrial equipment, air conditioners, motors, refrigerators, CNC machines, and other machinery in remote or off-grid locations. The inverter’s humanized safety design, such as closed electric parts to prevent shock and modular plug-in construction, simplifies maintenance and installation. Its data display function, featuring LCD and LED screens, provides real-time monitoring of input/output voltage, current, kWh, and fault diagnostics for quick troubleshooting.
