The Kunda 120M Solar Submersible Pump sits perfectly between the 110M and 150M heavy-duty setups. The 120M systems typically jump up to a much stronger power profile to maintain a robust water flow at deep elevations, often featuring an AC/DC dual-input controller.

Core System Features

Hybrid Intelligent Controller: Unlike the lower voltage DC-only pumps, Kunda’s 120M controllers are often hybrid. They prioritize solar power (DC) during the day and can automatically or manually switch over to grid power or an AC generator at night or during heavy cloud cover.
Maximum Power Point Tracking (MPPT): Maximizes power collection from the solar array, adjusting dynamically as the sun moves to prevent the pump from stalling.
Full Suite Protections: Includes internal safeguards against over-current, over-voltage, lightning surges, and dry-running (safeguarding the motor if your borehole runs low on water).

Solar Panel Setup Guidelines

To get the full 120-meter vertical push without straining the hardware, your solar array needs to properly match the controller’s voltage range:

Sizing the Array: For an 1100W pump, you want at least 1500W of panels. For a 2200W pump, aim for 3000W of panels.
Configuration: Because of the higher voltage requirement (often up to 300V open circuit), panels must be wired in a series string to build adequate voltage, rather than parallel.
