Mppt 2.2KW 4KW solar vfd solar pump inverter dc ac power input
VEIKONG VFD500-PV Technical data:
VEIKONG VFD500-PV series photovoltaic water pump driver is a special inverter for photovoltaic power generation to drive ac water pump. It inverts the direct current generated by solar modules into alternating current to drive various ac water pumps. The driver adopts high-precision and fast MPPT algorithm to track the output of the solar module through the maximum power point to maximize the drive of the water pump motor.
At the same time, it also supports ac input. When the power of the solar module is insufficient, it can accept ac input of the power grid or ac input of the generator to realize all-day work and meet various needs.

| Features | Your benefits | |
| High performance | Excellent overload performance: 150% 60s, 180% 3s, 200% 1s (normal test environment) High start torque performance: 0.5Hz, 150% Excellent current control capability: The inverter provides sufficient stable output torque when the load is suddenly changed to avoid trip operation | Improves productivity of machine Less interruptions of the production line |
| Improved energy savings | Integrated Eco-mode for V/f automatically adapts the motor magnetic flux to save energy. Improved special PID control with sleep mode helps to save more energy for pump application | Energy savings during low dynamic load cycles such as pump and fan. Increases the potential savings by up to 70%. Greatly reduces the return time of investment. |
| Multitude of function | With a new software platform, our VSDs offer more functions such as flexible V/F curve, 16 stage multi- speed control, command binding, industry specific functions, and many more. Easy to communicate with upper controller via built-in RS485 Modbus protocol. | No additional upper controller is needed for stand-alone machine, hence saving the system integration cost. Easy to do the system integration for large production line and long distance communication |
| Easy to use | Compact design and side-by-side mounting, din-rail installation. High accuracy motor parameters self-tuning function Supports pluggable keypad and extension keypad Wall-through mounting AVR (Automatic voltage regulation) technology | Makes it possible to use in smaller cabinets No need to set motor parameters anymore Easy to operate and maintain |
| Longer lifetime | Stable operation under main input voltage fluctuations. Reliable operation with net tensions between 380 V and 480 V (-15% / + 10%) Fully coated PCB Dust shield cover Better cooling and removable fan design | Wider voltage range, increases robustness of the drive in difficult environment Automatic adaptation in case of unstable power supply Longer life in high humid and high dust occasions Easy to maintain |
