ZIRI 3SH1.5-110/72V 0.75HP 110m 1.6m³/h Submersible Solar Pump

Product Description

The ZIRI 3SH1.5-110/72V is a 3” submersible solar pump with helical hydraulics, capable of lifting water up to 110 m with a maximum flow rate of 1.6 m³/h (1.3 m³/h nominal). Designed to operate exclusively on solar energy, it includes an external controller with MPPT tracking that supports a Vmp working range of 65–110 V and a maximum Voc of 150 V. Thanks to its continuous thrust and optimized electronic control, it offers reliable performance in narrow wells and elevated tanks without relying on the electrical grid or generators.

Main Features

• Helical (screw) hydraulics for high pressure: maximum head of 110 m with stable flow.
• Maximum flow rate 1.6 m³/h (nominal 1.3 m³/h), ideal for domestic supply and elevated tanks.
• 100% solar operation with external controller included; non-hybrid equipment.
• MPPT window: Vmp 65–110 V and Voc≤150 V; supports a series of 2–3 panels while maintaining the range.
• 3” format, ¾” discharge, approximate length 0.4 m and weight ≈8.4 kg: perfect for narrow boreholes.
• System power up to ≈0.9 kW (0.75 HP) with torque control for better starts at low irradiance.

Advantages or Benefits

• Zero operating cost: pumping with the sun, no fuel or electricity bills.
• More useful hours each day: MPPT makes use of available power in the mornings, evenings, and under clouds.
• Safety and simplicity: moderate voltages and short PV string reduce risks and simplify DC protections.
• Mechanical reliability: helical hydraulics maintain pressure at great heights with less wear.
• Quick installation: 3” diameter, ¾” discharge, and accessible external controller for maintenance.

Purpose or Applications

Water supply in off-grid homes, filling elevated tanks, livestock, and drip irrigation on properties with deep wells or medium-high pressure requirements. Especially useful when prioritizing head height over flow rate.

Technical Specifications

Compatibilities

Direct compatibility: external controller included for solar-only use. Recommended accessories: PV structures, solar cable and MC4 connectors, DC protections (PV circuit breaker and SPD), level switch/probe, check valve, safety rope, and ¾” piping.

PV recommendation: size a generator of sufficient power for the desired flow/head, always maintaining Vmp 65–110 V and Voc≤150 V. The stated power is indicative, not mandatory.

The ZIRI 3SH1.5-110/72V provides high pressure, low maintenance, and total autonomy for demanding solar pumping projects.
