Solar pump 400W Max Head 110 meters

A 400 W solar pump with a maximum head of about 110 m is a solar-powered submersible water pump designed to lift water from deep sources — such as boreholes and deep wells — up to high elevations using only energy from solar panels. These pumps are ideal for off-grid water supply, irrigation, livestock watering, and household uses where grid power isn’t available.

Key Features

✔ Rated Power: ~400 W solar direct-drive (DC) pump — runs directly off solar panels with no grid electricity.
✔ Maximum Head: ~110 m (vertical lift capacity). This means the pump can lift water up to this height in ideal conditions.
✔ Motor Type: Brushless DC (BLDC) motor — efficient, low maintenance, and long-lasting.
✔ Pump Type: Submersible borehole pump — designed to be placed inside the water source.
✔ Flow Rate: Typically range varies with head — higher head usually means lower flow. At ~110 m, flow might be moderate (e.g., 1 000–3 500 L/h depending on model).
✔ Controller: Often includes an MPPT (Maximum Power Point Tracking) controller to optimize solar panel power and protect the pump (dry-run, over-voltage, overload protection).
✔ Materials: Stainless steel or corrosion-resistant construction for use in boreholes/wells.

Performance

• High Lift Capability: A head of ~110 m means the pump can push water a long vertical distance — useful if your storage tank or outlet point is well above the water source, or if you’re pumping from very deep.

• Flow vs Head: As vertical lift increases toward the maximum head, the flow rate decreases. At lower lift heights, the pump delivers more water.

• Solar-Only Operation: These pumps run directly from solar power without batteries (though batteries can be added for backup or cloudy days).

• Recommended Panels: You’ll typically need a solar panel array sized above 400 W (often 500–800 W total) to ensure full performance at high head under real sunlight conditions.

Typical Uses

✔ Deep borehole pumping for homes and communities.
✔ Agricultural irrigation — drip or sprinkler systems.
✔ Livestock watering on farms and ranches.
✔ Filling overhead tanks to provide water pressure for household use.
