ROOMNY SOLAR WATER PUMP1

Here’s a breakdown of its characteristics:

• Application Focus: Primarily designed for drawing water from deep wells or boreholes. It’s often marketed for domestic use, livestock watering, and irrigation of small farms (e.g., up to 1 acre).
• Solar Powered: The pump operates directly from solar panels (PV arrays). This makes it an eco-friendly and cost-effective solution, especially in remote areas without reliable grid electricity or where fuel costs for traditional pumps are prohibitive.
• Submersible Design: ROOMNY SOLAR WATER PUMP1 is a submersible pump, meaning the pump unit itself is placed directly into the water source (borehole/well) to push water to the surface.
• Integrated System: These are often sold as a complete kit, typically including:
  • The DC submersible pump itself (often stainless steel for durability).
  • An MPPT (Maximum Power Point Tracking) controller: This is a crucial component that optimizes the power drawn from the solar panels to ensure the pump operates at its most efficient point, maximizing water output even under varying sunlight conditions. It also provides essential protections.
  • Solar panels: A specified number and wattage of solar panels (e.g., 2-4 panels, often around 100-340W each, depending on the pump’s power).
  • Submersible cable: Sufficient length of waterproof cable to connect the pump in the well to the controller on the surface.
  • Accessories: May include a float switch (for automatic on/off based on water level in a tank or well), splice kits, and connectors.
• Performance Specifications (Typical for “ROOMNY SOLAR WATER PUMP1” models):
  • Maximum Head: Around 30 meters (approx. 100 feet) – this indicates the maximum vertical distance it can push water.
  • Maximum Flow Rate: Around 1,100 liters per hour (L/hr) – this indicates the volume of water it can deliver.
  • Motor Type: Often uses a brushless DC (BLDC) motor for higher efficiency and longer lifespan compared to brushed motors.
• Protection Features: The accompanying MPPT controller typically provides safeguards such as:
  • Dry-running protection (prevents damage if the water source runs low).
  • Over-voltage/under-voltage protection.
  • Over-current protection.
  • Soft-start technology (reduces stress on the motor during startup).
• Market Position: Compared to premium brands like Grundfos or Lorentz, “ROOMNY” pumps are generally positioned as more affordable and accessible options, making solar water pumping viable for a wider range of users, particularly small-scale farmers and households in developing regions.
