ZIRI 3SH1.5-70/24V 0.3HP 60m 1.6m³/h Submersible Solar Pump

Product Description

The ZIRI 3SH1.5-70/24V is a 3” solar submersible pump designed for narrow wells and moderate flow rates, with a maximum head of 60 m and a flow rate of up to 1.6 m³/h. This is a solar-only unit that includes an external controller and operates within a wide MPPT range of Vmp 20–40 V (max Voc 48 V), making installation simple and safe for self-consumption water supply applications.

Main Features

• High-thrust helical hydraulics for water columns up to 60 m.
• Maximum flow rate of 1.6 m³/h (nominal flow 1.3 m³/h), ideal for domestic and light agricultural use.
• Direct solar operation with included external controller; non-hybrid system (does not operate on grid/AC).
• MPPT window: Vmp 20–40 V and max Voc 48 V; 1 panel in series (max number in series: 1) to ensure the range.
• 3” body, ¾” discharge, approximate length 0.4 m and weight 8.4 kg; easy handling and installation in wells.
• Motor power up to 0.3 kW with optimal torque control at low irradiance.

Advantages or Benefits

• Total energy autonomy: pumps using only solar power, with no electricity bills or generators.
• Controller MPPT start and tracking to extract maximum performance on cloudy days.
• Helical hydraulics maintain stable flow at high heads and in deep wells.
• Simplified installation: a single series of panels within Vmp 20–40 V and protection by Voc≤48 V.
• Reduced maintenance thanks to robust design and protected external electronics.

Purpose or Applications

Supply for rural homes, occasional irrigation of gardens, filling elevated tanks, livestock, and small agricultural installations. Its 3” diameter makes it perfect for narrow wells and ¾” discharge pipes.

Technical Specifications

Compatibilities

Direct compatibility: external controller included, sized to operate with 1 series of PV panels within Vmp 20–40 V (Voc≤48 V). Recommended accessories: panel mounting structures, solar cable and MC4 connectors, DC protections (circuit breaker and surge protection), level probe/switch, foot valve and in-line check valve, safety rope in stainless steel or polyamide, and ¾” piping.

Panel recommendation: it is recommended to install at least a PV generator of sufficient power for your target flow rate (e.g., from 200–300 W) as long as it operates within the MPPT range 20–40 V and Voc≤48 V. This is not a mandatory power, but a guideline for stable performance.

The ZIRI 3SH1.5-70/24V offers reliable, efficient, and 100% solar pumping for small to medium flow wells, providing simple installation and virtually zero operating cost.
