The Rutanpump JZDC3.5-48V-400W is a professional-grade solar-powered submersible screw pump designed for direct connection to solar panel arrays. Engineered for simplicity and efficiency, this unit operates at 48V DC with a rated power of 400W, eliminating the need for an external solar charge controller or battery bank. It is an ideal, cost-effective solution for agricultural irrigation and domestic water supply requiring a daily yield between 10,000 to 15,000 liters.
Constructed for extreme durability and long-term submersion in wells 4 inches or larger, the JZDC3.5-48V-400W features an industrial stainless steel pump body and 100% pure copper motor windings. This material choice ensures superior heat dissipation, corrosion resistance, and an extended service life. The high-lift screw mechanism generates a maximum head of 50 meters (150+ feet) and a substantial maximum flow rate of 3,000 liters per hour (3.0 m3/h).
This pump is uniquely designed to run dry without damage, removing the requirement for a float switch. It comes with a lengthy, integrated maroon power cable and a detailed wiring schematic on the pump body for straightforward, direct connection to two 250W solar panels. Note: This pump must not be used with an inverter.
