Solar Pump Controller

 Architecture

 

Features

  • Solar Panel Voltage set point calculation at every start.
  • True Maximum Power Point Tracking (MPPT)function.
  • Detection of sudden changes of conditions.
  • Stop criteria selectable (frequency and /or power).
  • Start criteria by solar panel voltage and time.
  • Dry pump detection function.
  • Water tank maximum level detection function.
  • Low power detection function.
  • Improved ease of operation and maintenance.
  • Remote multi-function keypad with backlit LCD screen available(option).
  • Functional safety compliance.
  • 1S013849-1 PL-e, Cat3 1EC61800-5-2 STO SIL3.
  • Global standard compliance.

Remote Monitoring System

We can monitor DC Voltage, Input Power, Current drawn from the Pump, Output Frequency, run time, Energy produced etc from remote.Also various reports & graphs can be viewed.Array Junction BoxArray Junction Boxes (AJB) basically collect DC power from PV strings. The collected power is then transferred to power Pump Controller.

Features

  • Fuse for overload protection on each string.
  • Blocking Diodes for reverse current flow protection.
  • MCB / Isolator on the output side to isolate the AJB from the Inverter.
  • Plug in type PV string input / output connectors.
  • With SPD (Surge Protective Device) for protection against Surges.
