the following example is for you reference.





1.Brief Introduction:

Fully automatic system using variable speed drive compatible with AC, 3-phase, submersible and surface mount pumps, and high efficiency PMSM Pumps. the system is composed of a PV generator, a pump and a solar pump drive. Based on the design philosophy that it is more efficient to store water rather than electricity, there is no energy storing device such as storage battery in the system. The system is prepared to be combined with a elevated water storage, e.g. Water tower or an uphill tank installation.  

 

2.Techincal parameters:
Recommended MPPT voltage range:

Vmpp 131 to 350 VDC for 1S (80V to 350VDC input, 3PH 110 to 220VAC output)

Vmpp 280 to 375VDC for 2S ( 150V to 450VDC input, 3PH 220 to 240VAC output)

Vmpp 486 to 750 VDC for 4T ( 250V to 800VDC input, 3PH 380 to 460VAC output)

Recommended input Voc and VmppVoltage:
Voc 180(VDC), Vmpp 155(VDC) for 1S model or 110V AC pumps

Voc 355(VDC), Vmpp 310(VDC) for 2S model or 220V AC pumps

Voc 621(VDC), Vmpp 540(VDC) for 4T model or 380V AC pumps

Rated output voltage:3-Phase,110V/160V/220V. 3-phase, 220V/380V/460V

Output frequency range:0~maximum frequency 600Hz.

  

3.Performance features:
MPPT ( maximum power point tracking), CVT (constant voltage tracking), auto/manual operation, dry run protection, low stop frequency protection, minimum power input, motor maximum current protection, flow calculating, energy generated calculating and water tank level detected.
