The Dayliff SUNFLO‑B2 400C3 Solar Pump is an efficient, solar‑powered submersible pump engineered to deliver reliable water supply from wells and boreholes without the need for grid electricity. This PV‑driven pump is ideal for rural, off‑grid, and remote locations where sustainable water delivery is needed for agricultural irrigation, livestock watering, and household use.
At its core, the SUNFLO‑B2 400C3 features a 400 W permanent magnet brushless DC motor that is oil‑filled and specifically optimized to convert solar energy into pumping power with high efficiency. This design minimizes energy losses and ensures consistent performance even under varying sunlight conditions.
A standout advantage of this model is its integrated MPPT (Maximum Power Point Tracking) controller, which intelligently maximizes the output from the connected solar panel array. The MPPT controller not only boosts daily water output — typically up to around 9 m³ per day at a 30 m head under standard conditions — but also provides comprehensive electrical protections such as over‑voltage, under‑voltage, over‑current, and dry‑run safeguards for safer and more reliable operation.
Constructed with durable and corrosion‑resistant materials, including a stainless steel housing, polycarbonate impellers, and cast iron chambers, the pump is built for long service life even in demanding environments. Its submersible design allows it to be fully immersed in water, eliminating the need for priming and improving overall reliability.
The SUNFLO‑B2 400C3 can operate directly from solar panels without batteries, making it a low‑maintenance and cost‑effective water pumping solution. Optional battery integration is also supported for extended operation during periods of low sunlight, offering flexibility based on water demand and local conditions.
Typical setup for this model includes a recommended PV configuration of two 350 W solar panels, allowing the system to efficiently harness available solar energy for dependable daily water delivery.
Overall, the Dayliff SUNFLO‑B2 400C3 Solar Pump combines renewable energy efficiency, smart power optimization, and rugged construction to provide a dependable, low‑maintenance solution for off‑grid water supply needs. Whether for farms, villages, or remote homesteads, it’s a sustainable choice that delivers consistent water flow powered by the sun.
