Product Description

SG200 380V 0.75k to 5.5kw series solar pump inverter compatible with dual supply mode

The solar pump inverter operates in dual supply mode either with a three phase input supply from the grid or with DC input supply from PV cells.

A four-pole changeover switch enables switching between the two supply modes. At a given time only one power supply (PV cell or grid) can be connected to the drive.

The DC and AC also can connected to inverter at the same time (Hybrid input)

 

Solar Pumping System overview
Solar pumping systems can be applied to all forms of daily use, water pumping for drinking water supply for remote villages and farms without connection to the water grid, for agricultural use such as livestock watering, agricultural irrigation, forestry irrigation, pond management, desert control, and industrial use such as waste water treatment etc.

 

The PV generator, an aggregation of PV modules connected in series and in parallel, absorbs solar irradiation and converts it into electrical energy, providing power for the whole system. The pump drive controls and adjusts the system operation and converts the DC produced by the PV module into AC to drive the pump, and adjusts the output frequency in real-time according to the variation of sunlight intensity to realize the maximum power point tracking (MPPT). The pump, driven by 3-phase AC motor, can draw water from deep wells, rivers and lakes and pour it into storage tanks or reservoirs, or be connected directly to the irrigation system, fountain system, etc. According to the actual system demand and installation condition, different types of pumps such as centrifugal pump, axial flow pump, mixed flow pump or deep well pump can be used.
Solar pump system constitution.

Providing clean, environmentally safe water for livestock in sufficient quantities continues to be a major concern for farmers and ranchers. Abundant water in remote locations in needed to insure that grasslands are grazed evenly.

 

Solar pump Inverter has following advantages: 

  • Ground water lowering,
  • Irrigation systems
  • Industrial Application
  • Drip irrigation& sprinkler
  • Tank/ cistern filling
  • Wildlife refuge, Fountains
  • Rural water supply for ranches, cabins, and cottages

Solar arrays selection table for inverter and pumps.

Take solar panels Voc38VDC, Vmp 31VDC, 265W.
Please check if enough DC voltage for system, Voc and Vmp. If the input is correct, the inverter will not work properly. If the output frequency is not high, lower than 50/60Hz even in good sunlight radiation, please check if enough solar panels have been connected. The total power should be at least bigger 1.3 times than of rated power of pumps.
