Import 20kw Split-Phase Inverter 120/240vac Output — Buy in wholesale FOB from Supplier in China

The SANDI SDP series 20kW pure sine wave inverter is a static power converter designed for industrial and commercial renewable energy applications. This split-phase inverter delivers 120/240Vac output from DC input, transforming battery or solar DC power into clean sinusoidal AC power suitable for sensitive electronic equipment. The unit employs SVPWM (Space Vector Pulse Width Modulation) technology with a sixth-generation Mitsubishi IPM (Intelligent Power Module) for stable performance and long service life. The DSP28335 chip from Texas Instruments handles central processing for quick and accurate response times.

The inverter features a steel chassis with aluminum heatsink for thermal management, copper windings in the isolation transformer, and PCB electronics throughout. The modular and plug-in design allows for convenient maintenance and reduces repair costs. Input and output are completely electrically isolated using an isolation transformer, with circuit breakers installed on both sides. The unit supports both DC (Battery/Solar) priority and AC mains bypass priority modes, configurable via the LCD panel. Two start modes are available: Reduction Voltage Start and Variable Frequency Start, selectable based on load type.

This inverter serves solar power systems, telecommunications infrastructure, backup power applications, and industrial facilities requiring clean sinusoidal power. Typical loads include air conditioners, electric motors, refrigerators, fluorescent lights, televisions, CNC machines, electric tools, and pumps. The product targets importers and distributors serving renewable energy integrators, telecommunications companies, and commercial backup power system installers worldwide. Buyers should verify specific DC input voltage requirements and configure overload, short circuit, and battery voltage protection parameters based on their application.
