Sun Great Series Solar Pump Drives

Solar pump drives advantages:
Kewo sun great series solar  pump drive is positioned in environmental-friendly and economical PV market, the product is applicable to PV pumping system, replaces water storage with electric storage and needs no battery modules. The direct current generated by solar modules is to the inverter and then converted into the alternating current to drive various pumps directly. Additionally, the output frequency is adjustable in real time according to sunlight intensity change.

Specification:
*0 to **0VDC , **0V/**0V/**0/**0V AC output, 0.*5/1.5kw.
**0 to **0VDC , ******0VAC output, 0.*5 to 3.7kw
*******0VDC , ******0VAC output, 0.*5 to **0kw

Descriptions and Features
We are professional solar pump drive manufacturer, and provide high end solar drive, which developed based on our AC grid motor control drive.

It has following features.
1. Built-in MPPT function, Maximum power point tracking functionality ensures that you get the most power output possible from your solar panel and maximizes the performance of your pump throughout the day.
2. Built-in flow measurement and sensorless flow calculation.  And easy to get how much energy generated by this system with generated energy and calculating
3. Advanced function automatic start and stop of the drive when there is enough power available. ( auto/manual)
4. Multiple pump motors with a single drive control standard asynchronous motors as well as more efficient permanent magnet synchronous motors. (PMSM)
5. Best off-grid solution Where electricity is very erratic and unpredictable, farmers need not to depend on grid electricity for their agricultural requirements
Remote monitoring  With the addition of optional GPRS modules you can monitor and configure drive and application parameters from anywhere via Modbus RTU

Protection features
Electronic monitoring gives the controller the capability to monitor the system and automatically shut down in the even of: Dry run conditions- with smart pump monitoring, High voltage surge, Low voltage, Open motor circuit, Short circuit, Over heat, Earth fault, Phase missing…

Technical specification 

Excellent hardware design 
Sun Great solar pump drive developed based on S**0 high performance vector control AC drive with software MPPT and hardware updated.
The S**0 vector control drive is renowned for his excellent hardware deign and powerful software performance, the failure rate less than 0.6% for 3 years.
Excellent hardware design
Total brand new hardware design with two CPUs control way, which follow ABB and Schneider

Excellent software design 
Software updated with MPPT design based on following solar drive, ABB, Danfoss, Delta, Lorentz, INVT, SAJ,
  Control mode: VF, vectorization VF, senorless vector control 1, sensorless vector control 2
  MPPT function: always performance MPPT for gain highest efficiency
  CVT: When sunlight is good, can select CVT control for excellent stable frequency output.
  Dry run function: When little water or no water for pumping to protect pumps.
  Maximum current protection: set maximum current protection is available
  Minimum solar power: When low power , drive no work
  Stop frequency: Lower than stop frequency, drive no work
  Sleep mode: if lower than sleep voltage, drive go to sleep, it will wake up when DC voltage rise.
  Flow and generated energy calculating and monitoring
  A lot of  fault protection. Short circuit, ground short circuit, phase loss, over current, overheat…
  Built in RS**5 interface, it is easy to connect GPRS remote controller.
We developed it base on ABB, Lorentz, Delta, Danfoss , INVT and VEICHI***- That is why we are
Good performance and better.
