VFD700 can convert the direct current generated by solar panels into alternating current to drive photovoltaic pumps.

2. Adjustable output frequency

It is capable of adjusting the output frequency automatically in line with the irradiation intensity.

3. Maximum Power Point Tracking function

Built-in with the MPPT (maximum power point tracking) function, so the photovoltaic pumping system can produce better power outputs to improve the working efficiency of pumps.

4. Store water, instead of storing power

The energy storing devices such as battery have been eliminated from the system, so all the AC power can be directly used to drive pumps with the lowest energy loss.

5. Asynchronous and synchronous motors are available

While our previous modal can only work with asynchronous 3 phase induction motors, the VFD700 series can work perfectly with both asynchronous and synchronous 3 phase induction motors.

6. Support various kinds of pumps

Both the surface mount and submersible pumps are compatible with the photovoltaic pumping system.

7. Remote monitor function

VFD700 has inbuilt S200-GPRS that users can monitor the whole photovoltaic pumping system online at home or other place via our PC remote monitoring system. On the basis of user-defined curve, VFD700 can automatically calculate the present flow speed, flow per day, present power, total generation and more status parameters of the solar pumping system.

8. Pc tool commissioning

As VFD700-PV has developed with the PC tool commissioning , so users can upload and download technical data and duplicate the data excel to monitor the PV pumping system offline at any time.

9. Complete protections

VFD700 has designed with a wide range of protection functions such as water fulfill, dry run, low frequency, high voltage, short circuit, over heat, phase missing and more.

10. User-friendly

VFD700 is designed with an intuitive operation panel along with detailed instructions, so it is convenient in installation, operation and maintenance. Additionally, the cooling and shielding effect is great.

Besides, Veikong Electric also provides other solar energy products such as PV inverter at wholesale price.

Soft Starter

S6000

The soft start motor has Intelligent digital motor soft start equipment system with the complete protection function.

The soft starter reduces the cost of system cost and extend the service life of the system..

It is a new ideal alternative for traditional star triangle starter and self-coupling decompression starter.

It improve the reliability of system and compatible with all the functions of starting equipment.

General purpose soft start motor control applications where traditional across-the-line starting or wye-delta starting would typically be appropriate. Typical application types include:

  • Motor Fan: Use soft starter instead of conventional starter, to realize the smooth start.
  • Compressor: The soft starter limit the startup current, reduce the abrasion and mechanical impact, reduce the heat of motor, prolong the working life, save the maintenance cost.
  • Crusher: The block protection of soft starter prevent the motor being over burnt and hurt damaged come from mechanical fault and block.
  • Transmission Machine: Soft startup and presetting slow movement realize smooth, gradual start, to avoid products movement and liquid overflow.
  • Pump: The control of soft starter reduce the water hammer result from liquid impact, saving maintenance cost for system.
  • Grinder: The soft start reduce the abrasion of wheels, lighten the maintenance cost and tiem.
