0.75 kW Single Phase to Three Phase Solar Pump Inverter, AC 220V

This 0.75kW single-phase to three-phase solar pump inverter converts DC solar power or 220V single-phase AC input into 220V three-phase AC output, enabling standard three-phase pumps to run on solar or single-phase grid power. The built-in MPPT controller tracks the optimal power point of the PV array (recommended range 250~400V) for up to 98% system efficiency. Power factor >0.99, output frequency 0~50/60Hz, no condensation at humidity <95% RH. RS485 communication allows easy integration and remote monitoring. Suited for agricultural irrigation, desert greening, and small-scale water supply systems.

Features

1. High-Efficiency MPPT Control: This 0.75kW pump inverter utilizes advanced MPPT technology to track the optimal operating point of solar panels in real time, optimizing both voltage and current for system efficiency of up to 98%.
2. Smart Sleep Mode: Automatically adjusts its operation based on sunlight intensity. The water pump inverter enters sleep mode during low sunlight to save energy and quickly resumes operation when sunlight increases, maximizing solar resource utilization.
3. Water Level Adaptive Control: Integrated with water level sensing, the VFD solar inverter automatically stops when the water level is high to prevent overflow and restarts when the water level is low to avoid dry running, enabling unattended automated management.
4. Intelligent User Interface: The 220V solar pumping inverter features an intuitive control panel with support for water level detection and smart control, ensuring user-friendly and safe operation while preventing equipment damage.
5. Fault Self-Protection: Built-in multiple protection mechanisms immediately activate self-protection in case of faults, ensuring stable system operation and enhancing overall system reliability.
6. AC Bypass Backup: Includes an integrated AC bypass function. During insufficient or no sunlight periods, the 3-phase solar pump controller automatically switches to an AC power supply, ensuring uninterrupted water pumping.

Details

Air Vents

Good-quality 0.75kW solar water pump inverter has high-density ventilation ports for excellent cooling, ensuring stable operation in high-temperature environments.
