Product Overview

VFD500-PV Solar Pumping Inverter is a new generation controller for solar pumping applications.

Key Features & Characteristics

• Maximizing power generation efficiency of solar modules with the use of advanced MPPT control technology and automatic MPPT voltage tracking.
• Adjust water outflow of pumps quickly on basis of sunlight intensity change.
• Automatic hibernation and wake up – hibernate at high water level and wake up at low water level; hibernate at sunrise and sunset and wake up at strong sunlight.
• Built-in C3 EMC filter and DSP technology and Infineon PIM design, with functions of light weak protection, dry run and low voltage, full water warning, overvoltage and over temperature protection.
• Advanced calculation for Pump flow and LCD monitoring display.
• Automatic running without any commissioning in keypad control and GPRS monitoring option.
• Dual supply capability with change over switch – solar and grid compatible.
• Special MPPT+PID function for better and more stable water supply.
• Independent air duct design, effectively preventing dust entering into inverter, causing short-circuit and other faults and improving reliability.
• Use bigger air volume and long-life cooling fan effectively reduces the internal temperature rise of the inverter and ensures reliable and stable operation of inverter.
• Designed for 10 years of maintenance free operation. Cooling fan, capacitors, relays, and IGBTs have been carefully selected and designed for a life expectancy up to ten years.

Optional Accessories

GPRS remote monitoring – VEIKONG solar pump inverter GPRS system is a professional monitoring system platform managing solar pump plants. It supplies water volume monitoring and operation of inverter from anywhere at any time. It's convenient to visit real time and historical data via web or IOS & Android APP anytime and anywhere. This easy-to-use platform make monitoring of solar pump systems simple and convenient, far reducing operate time and monitoring costs as well.

LCD keypad is optional. LCD keypad can monitor 4 parameters at the same time. LCD keypad with detailed parameter explain, no need use user manual, more user friendly. LCD keypad with copy and update and download function, widely used for government projects and big farms.

AC Output Reactor – smoothing circuit, efficient from IGBT motor drives, so as to extending service life of electric motors. Reduce motor noise and eddy loss. Reduce the leakage current resulted from the output of high harmonic. Protect the electronic power switch within the inverters.

Sine wave Filters – specially designed to improve the wave form and avoid over voltages in the motors of VSD system. Reduction of the overvoltage peaks caused by PWM and, therefore, a lower wear of motor insulation systems and bearings; reduction of motor noise and improves motor efficiency; improve the quality of the output wave of the PWM; attenuation of the interference emissions radiated by the conductors between the modulator and motor and improves the entire EMC load on the equipment.
