    Solar Pump Inverter (Controller) SWP1K5H-E-V1 / SWP2K2H-E-V1

    SWP1K5H-E-V1
    SWP2K2H-E-V1

    Product Introduction

    Solar Pump Inverter SWP1K5H-E-V1 / SWP2K2H-E-V1 is a compact, high-efficiency photovoltaic pump controller designed for small to medium solar water pumping systems. It converts DC power from solar panels into stable AC output to drive water pumps directly, ensuring reliable water delivery even in remote areas without grid access. With intelligent MPPT control and comprehensive protection functions, the inverter maximizes solar energy utilization while protecting the pump system for long-term operation.

    Product Features

    • High-Precision MPPT Control - Advanced Maximum Power Point Tracking technology continuously optimizes the operating point of PV arrays, enabling up to 99% tracking efficiency and stable pump operation under changing sunlight conditions.

    • Flexible Power Input Design - Supports DC power from solar panels and AC power from grid or generator, allowing uninterrupted water supply during low irradiation or emergency conditions.

    • Intelligent Pump Protection - Built-in dry-run detection, phase loss monitoring, and automatic fault response effectively reduce pump damage and maintenance costs, extending overall system lifespan.

    • Compact Structure, Easy Installation - Lightweight design with forced air cooling allows wall-mounted installation in pump rooms or control cabinets, ideal for projects with limited space.

    Description

    Product Description

    The SWP1K5H-E-V1 / SWP2K2H-E-V1 solar pump inverter is engineered to deliver stable water pumping performance using solar energy as the primary power source.
    By dynamically adjusting output frequency based on solar irradiation, the inverter enables smooth motor operation without batteries, reducing system cost and maintenance complexity.

    The integrated protection logic automatically responds to abnormal conditions such as low water level, voltage fluctuation, or motor faults, ensuring safe and unattended operation. Its communication interface allows easy system monitoring and integration into larger solar pumping or microgrid projects.

    Application Scenarios

    • Agricultural Irrigation
      Ideal for farmland irrigation, drip irrigation, and small agricultural water supply systems.
    • Livestock Watering
      Reliable solution for ranches and pasture areas with no stable grid electricity.
    • Rural & Remote Water Supply
      Suitable for villages, islands, and off-grid communities requiring sustainable water access.
    • Water Transfer & Storage
      Supports pumping water into tanks or reservoirs for domestic or commercial use.

    Q1: What type of pump can this solar pump inverter drive?

    A: It is designed for three-phase AC water pumps within the rated power range.

    Q2: Can the inverter work without batteries?

    A: Yes. The inverter directly uses solar power and adjusts pump speed according to sunlight, eliminating the need for batteries.

    Q3: What happens if there is no water in the well?

    A: The inverter automatically activates dry-run protection and stops the pump to prevent damage.

    Q4: Can I use grid electricity as backup power?

    A: Yes. The system supports both DC (PV) and AC input, enabling flexible hybrid operation.

    Q5: Is this inverter suitable for remote installation?

    A: Absolutely. It supports unattended operation, low maintenance, and stable performance in harsh environments.
