    Description

    Product Description

    The SWP Solar Pump Inverter Series is engineered for direct PV to AC water pumping solutions — eliminating battery dependency while making the most of solar output. Leveraging advanced MPPT algorithms used in top solar pump inverters, it continuously seeks the PV array’s best operating point for peak efficiency and sustained water output.

    This series adjusts motor speed in response to solar irradiation, ensuring optimal performance throughout daily sunshine cycles. Auto start/stop and frequency modulation reduce mechanical stress on pumps, enhancing overall system durability. Built-in protective logic guards against common failures like dry-running, low solar power, and electrical anomalies, giving operators peace of mind in remote or unattended environments.

    Typical Application Scenarios

    Agricultural Irrigation — direct solar pumping to irrigate fields and orchards with low operating cost.
    Livestock & Farm Water Supply — reliable rural water delivery for troughs and watering stations.
    Off-Grid Drinking Water Systems — clean PV-powered pumps for rural village water access.
    Landscape & Environmental Projects — park fountains, pond circulation, greenbelt irrigation.

    Q1: Do I need batteries with a solar pump inverter?

    A: No — this series is designed for direct PV-to-AC pumping without battery storage, which simplifies installation and reduces cost.

    Q2: Can the controller adjust to varying sunlight?

    A: Yes — the MPPT tracking and smart output frequency automatically adapt to real-time sunlight intensity.

    Q3: What types of pumps does this support?

    A: Compatible with both surface and submersible AC water pumps, and selection depends on site requirements.

    Q4: How does the inverter protect the pump?

    A: Built-in protections cover dry-run, over-current, over-voltage, overload, under-voltage, and other common electrical issues.
