Kunda 110M Solar Submersible Pump

The Kunda 110M Solar Submersible Pump (192V) is a heavy-duty, high-lift commercial-grade solar pump designed for deeper boreholes and large-scale agricultural irrigation.

Stepping up from the 90M variant, this model runs on a much higher voltage system to efficiently handle high-volume water transfer over long vertical distances.

Key Specifications & Performance

Core System Features

• High-Power Brushless Motor: The 1500W brushless DC motor provides low-noise operation and high thermal efficiency, meaning it uses less solar power to lift heavier volumes of water.

• Heavy-Duty MPPT Controller: This system comes bundled with an external high-voltage control box. It actively manages the fluctuating energy from your solar panels, protects against over/under-voltage, and features soft-start tech to prevent sudden wear on the motor.

• Intelligent Dry-Run Protection: Sensors built into the control unit automatically shut the pump down if the water source drops below a safe level, restarting automatically once the well recovers (typically after 30 minutes).

Solar Panel Configuration Requirements

Because this pump operates at a high native 192V DC, planning your solar array correctly is essential to avoid starving or frying the controller:

• Total Wattage: You should aim for a total solar capacity of at least 1950W to 2200W (Rule of thumb is minimum $1.3 \times$ the pump’s 1500W motor rating).

• Wiring Design: You will need to string several standard solar panels in series to build up to the required 192V working voltage.

  Example Setup: Wiring 6 to 8 standard 330W–400W panels in a single series string (depending on the panel’s individual Open Circuit Voltage, or $V_{oc}$) usually perfectly satisfies the controller’s voltage input range.
