1. Features of Solar pump inverter.

Multiple pump motors with a single inverter control Standard asynchronous motors as well as more efficient permanent magnet syn. motors. (PMSM)

Save in energy costs and maximize productivity
solar pump inverters ensure reliable power supply throughout the day with on and off-grid compatibility

Save environment
Harnessing the power of sun provides an environmentally friendly pumping without producing any CO2 emissions

Easy install and operation and little parameters Configuring.
End user ,who never used inverter before, can Install and operation it very well.

Reduce maintenance costs
The inverters can be equipped with remote monitoring options, reducing maintenance trips to the site

Reduce operational risk
Embedded pump-specific features such as dry run detection, Minimum power input protection Maximum current protection Minimum frequency running protection Flow and generated energy showing

3. SDD600 Solar pump inverter--Hardware design

High cost performance and very strong practicability

Solar pump inverter developed based on SDD630 high performance vector control AC inverter with software MPPT and hardware updated.
The SDD630 vector control inverter is renowned for his excellent hardware deign and powerful software performance, long service life design.

Excellent hardware design .
● Ti ‘s 32 bit DSP ( 28034/35), Germany Infineon intelligent modules;
● Enhanded and 4 layer PCB design PCB wire corssing
● Low temperature rising design with delta fans
● Good quality components selecting,
● Independent cooling duct for lower temperature rising.

4. SDD600 Solar pump inverter--Software design

Software updated with MPPT design based on following solar inverter, ABB, Danfoss, Delta, Lorentz, INVT, VEICHI, SAJ.

√ Control mode: VF for induction motor pumps, open loop vector control for PMSM high speed pumps
√ 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 input power: When low power input, inverter no work
√ Stop frequency: Lower than stop frequency, inverter no work
√ Sleep mode: if lower than sleep voltage, inverter 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 RS485 interface, it is easy to connect GPRS remote controller.

We developed it base on ABB, Lorentz, Fuji, Danfoss , INVT and VEICHI---- That is why we are Good performance and better.

Solar pump control software developed
Based on SDD630 high performance
Vector control AC frequency inverter
Dual mode DC and AC input.

SDD660 solar drive developed based on SDD630 high performance vector control drive.
When it used for solar pump control, the PID and vector control can’t work.
