Product Description

The Dayliff SUNFLO‑A 270H Solar Pumping System is a reliable, low‑maintenance solar water supply solution specifically designed for off‑grid applications where conventional electricity is unavailable or costly. It’s ideal for domestic water supply, livestock watering, and small‑scale agricultural irrigation from boreholes or wells, harnessing solar energy to deliver consistent water flow with minimal operating costs.

At the heart of this system is the SUNFLO‑A 270H submersible pump, built with a helical rotary screw design and a stainless steel body with a rubber stator for durability and efficient performance. The pump includes an in‑built controller, allowing it to be connected directly to solar PV modules without needing additional control electronics. This simplifies installation and reduces the number of components required.

The unit is powered by a 36 V DC permanent‑magnet, oil‑filled, brushless motor specifically engineered for high efficiency with solar PV power. For optimal performance, the solar array should be sized at about 130 % of the motor’s rated power so that it effectively captures maximum available sunlight and drives the pump throughout the day.

Under standard test conditions of 1000 W/m² solar irradiance and 25 °C ambient temperature, the SUNFLO‑A 270H can deliver an indicative output of approximately 3 m³ of water per day at a 50 m head (vertical lift), although actual daily performance will vary depending on site irradiation levels, setup, and seasonal sunlight variation.

This pumping system is supplied as a ready‑to‑install kit, including carefully matched solar PV modules with connectors, submersible drop cable, a DC solar isolator with MCB control, safety rope, and pipe fittings needed for installation — making setup more straightforward and organized.

The pump’s IP68 enclosure rating ensures it can be safely submerged in water, and it performs well when pumping clean, chemically non‑aggressive water with low sand content (< 0.1 %). Other operating parameters include a recommended maximum immersion depth up to 20 m, a maximum liquid temperature of +40 °C, and compatibility with boreholes with a minimum diameter of 100 mm.

Overall, the Dayliff SUNFLO‑A 270H Solar Pumping System combines solar‑driven efficiency, durable construction, and ease of installation to deliver a dependable water pumping system that’s ideal for remote and off‑grid water supply needs — offering long‑term performance with minimal running costs.
