Agriculture and Irrigation

Agricultural water pumping systems fail when the solar array, pump and inverter are mismatched or when the system cannot handle variable sunlight and peak demand.

Overview

What This Application Demands

Agricultural water pumping systems fail when the solar array, pump and inverter are mismatched or when the system cannot handle variable sunlight and peak demand. WeBright delivers complete solar water pumping systems pre-configured for the pump type, flow rate and head height, with the inverter, panels, mounting and cable included in one shipment so the system works from day one.

Pain Points

What Goes Wrong

  • Pump fails to start under low sunlight because the inverter is not MPPT-equipped
  • Inverter trips during startup due to mismatched voltage or pump motor surge
  • Pump and inverter arrive from separate suppliers, leading to compatibility issues
  • No automatic control means the system runs at full power even when water is not needed
  • Pump is not rated for continuous operation under solar input without thermal protection
Customer Needs

What the Buyer Actually Needs

  • An inverter with MPPT and AC complementary input for consistent pump operation
  • A system sized for the required flow rate and total dynamic head
  • A pump compatible with DC voltage and permanent magnet motor design
  • One shipment with panels, inverter, mounting, cable and connectors included
  • Full automatic operation with multi-functional control and overload protection

FAQ

Agriculture and Irrigation Questions

What pump types are compatible with your solar inverters?

Permanent magnet DC pumps with 110V 110Hz, 1″ or 2″ outlet, and well diameter up to 125mm are supported.

Can the inverter run on AC power if solar is unavailable?

Yes. The inverter supports AC complementary input for grid backup during low sunlight or night operation.

What is the maximum power capacity of your solar pump inverters?

Inverters are available from 400W to 110kW, with 220V/380V 1-phase or 3-phase output.

Is the mounting structure included in the kit?

Yes. The mounting structure is designed for roof, ground or pole installation and ships with the system.

Do you offer custom system design for specific irrigation needs?

Yes. Customized service is welcomed. Provide the pump type, flow rate and head height for a tailored solution.
