In many rural water supply, livestock, farm and community projects, the real requirement is not simply to buy a pump or an inverter. The actual requirement is clear: lift water from a borehole and store it safely in a tank, with stable operation, simple maintenance and lower running cost.<\/p>\n

This is why HOBER describes this solution as a Borehole-to-Tank Water Supply System<\/strong>, not only as a solar pump inverter product. For distributors, installers and water project contractors, this way of thinking is closer to the real job site.<\/p>\n

\n

A good borehole-to-tank system should answer four questions before installation:
\nCan the pump reach the required head?
\nCan the solar array provide enough power?
\nCan the tank be protected from overflow?
\nCan the system stop safely when the borehole has low water?<\/p>\n<\/blockquote>\n

What Is a Borehole-to-Tank Water Supply System?<\/h2>\n

A borehole-to-tank water supply system uses a submersible pump to lift underground water from a borehole and deliver it to an elevated or ground-level storage tank. The tank then supplies water to houses, farms, livestock points, irrigation lines or local distribution networks.
\n\"solar<\/p>\n

In a solar pumping project, the system normally includes:<\/p>\n

    \n
  • \u0627\u0644\u0623\u0644\u0648\u0627\u062d \u0627\u0644\u0634\u0645\u0633\u064a\u0629<\/li>\n
  • Solar pump inverter or pump controller<\/li>\n
  • Submersible borehole pump<\/li>\n
  • Borehole cable and pipe<\/li>\n
  • Water level sensor or dry-run protection<\/li>\n
  • Tank level control<\/li>\n
  • Optional grid or generator input for hybrid operation<\/li>\n<\/ul>\n

    For the end user, the tank is the most visible part of the system. But for the installer, the critical work is hidden in sizing, protection settings and matching between pump, inverter, PV array and borehole conditions.<\/p>\n

    Why Tank Storage Is Often Better Than Battery Storage<\/h2>\n

    In many water pumping projects, the best storage is not a battery. It is water storage.<\/p>\n

    A tank is usually easier to maintain, more durable in hot environments and more suitable for daily water demand. Instead of storing electricity first and converting it later, the system pumps water during sunny hours and stores water directly in the tank.<\/p>\n

    This is especially practical in Africa, the Middle East, South America and Southeast Asia, where many customers need reliable water supply but want to avoid high battery replacement cost.<\/p>\n

    The Main Sizing Factors Installers Should Check<\/h2>\n

    A borehole-to-tank system should not be sized only by pump power. A 3 kW pump in one project may be easy to run, while another 3 kW pump may fail because of high head, long cable distance or poor PV configuration.<\/p>\n

    \u0625\u062c\u0645\u0627\u0644\u064a \u0627\u0644\u0631\u0623\u0633<\/h3>\n

    Total head includes borehole depth, vertical height to the tank, pipe friction loss and any pressure requirement. If the head is underestimated, the pump may run but deliver very little water.<\/p>\n

    Daily Water Demand<\/h3>\n

    A livestock project, a village water point and an irrigation project may all use borehole water, but their daily water demand is very different. This affects pump selection, PV capacity and tank size.<\/p>\n

    PV Array Configuration<\/h3>\n

    The solar panels must match the inverter input voltage range and the pump load. Too few panels can cause weak operation. Incorrect series or parallel connection can create unstable start-up or protection alarms.<\/p>\n

    Tank and Borehole Protection<\/h3>\n

    A proper system should stop when the tank is full and protect the pump when water level is too low. These functions reduce site visits and protect the installer\u2019s local reputation.<\/p>\n

    Why the Solar Pump Inverter Matters<\/h2>\n

    The solar pump inverter is the control center of the system. It converts solar DC power into AC power for the pump, tracks the solar panel output through MPPT control, and manages protection functions such as dry-run, overload, overvoltage, undervoltage and tank control.<\/p>\n

    For borehole projects, the inverter should be selected not only by kW rating, but also by pump voltage, motor type, cable distance, PV input range and application conditions.<\/p>\n

    HOBER solar pump inverters are designed for solar pumping applications and support inverter sizing, PV matching, wiring guidance and parameter support for distributors and installers.<\/p>\n

    Common Problems in Borehole-to-Tank Projects<\/h2>\n
      \n
    • The pump power is correct, but the head calculation is wrong.<\/li>\n
    • The borehole cable is too long without proper protection or output reactor consideration.<\/li>\n
    • The PV array voltage is too low for stable operation.<\/li>\n
    • The tank has no reliable level control.<\/li>\n
    • The installer does not receive enough technical support after delivery.<\/li>\n<\/ul>\n

      These problems are not always caused by bad products. Very often, they come from incomplete system design. This is why HOBER focuses on complete solar pumping solutions instead of only supplying inverter hardware.<\/p>\n

      Who Is This System Suitable For?<\/h2>\n

      Borehole-to-tank water supply systems are suitable for:<\/p>\n

        \n
      • Rural water supply projects<\/li>\n
      • Livestock drinking water projects<\/li>\n
      • Farm and irrigation water storage<\/li>\n
      • Schools, clinics and community water points<\/li>\n
      • Remote areas with limited grid access<\/li>\n
      • Water project contractors and borehole drilling companies<\/li>\n<\/ul>\n

        HOBER\u2019s Role in the System<\/h2>\n

        HOBER provides solar pump inverters, pump matching support and system configuration guidance for borehole-to-tank applications. For B2B partners, our goal is to help reduce installation uncertainty and after-sales pressure.<\/p>\n

        Before recommending a solution, we normally check pump power, pump voltage, borehole depth, total head, required flow, panel specification and site power conditions. This helps the distributor or installer prepare a more reliable proposal for the project owner.<\/p>\n

        \u0627\u0644\u062a\u0639\u0644\u064a\u0645\u0627\u062a<\/h2>\n

        Can a borehole pump run directly from solar panels?<\/h3>\n

        In most AC pump applications, the pump needs a solar pump inverter to convert solar DC power into suitable AC output and manage pump protection.<\/p>\n

        Do I need batteries for a borehole-to-tank system?<\/h3>\n

        Usually not. For many water projects, pumping water during sunny hours and storing water in a tank is more practical than using batteries.<\/p>\n

        What information is needed for system sizing?<\/h3>\n

        Pump power, voltage, total head, flow requirement, borehole depth, tank height, solar panel specification and cable distance are important for correct sizing.<\/p>\n

        Need Support for a Borehole-to-Tank Project?<\/h2>\n

        HOBER works with solar pump distributors, installers, borehole drilling companies and water project contractors. If you have an ongoing borehole-to-tank water supply project, our team can help check inverter sizing, PV matching and system configuration.<\/p>\n
