ZIRI 4SC3-185 3HP 140m 6m³/h Hybrid Submersible Solar Pump

Product Description

The ZIRI 4SC3-185 3CV Hybrid Submersible Solar Pump is designed for demanding installations that require high pressure with stable flow. It delivers up to 6 m³/h and a head of 140 m in working configuration, integrating the control electronics and MPPT into the pump body itself for a clean, safe, and quick installation. Its hybrid architecture allows direct operation with photovoltaics and, when necessary, with grid or generator at 90–240 V AC. For those who prefer the electronics outside the well, the external ZIRI controller is offered as an option.

Main Features

• High pressure and good flow: 6 m³/h and 140 m head (maximum for the family up to ≈185 m depending on curve).
• Integrated MPPT with wide PV window: Vmp 60–380 V and Voc max. 440 V (recommended to operate in the 280–380 V range for best performance).
• AC mode 90–240 V for continuous backup with grid or generator.
• 4” hydraulics with 1¼” outlet, optimized for long lines and sprinkler irrigation.
• Robust 3 CV motor for prolonged operation in solar pumping.
• Professional construction: approx. length 1.15 m and approx. weight 18 kg for installation in standard casing.

Advantages or Benefits

• Simplified installation and fewer components on the surface, reducing the risk of wiring errors.
• Maximum utilization of PV thanks to the MPPT, which optimizes voltage and current at all times.
• Guaranteed continuity: switches to AC when solar radiation is insufficient or for nighttime needs.
• Maintenance flexibility by allowing the option of an external controller if accessible electronics are desired.
• Efficiency and durability in intensive working environments with pressurized irrigation and elevated tanks.

Purpose or Applications

Ideal solution for deep wells, multi-line sprinkler irrigation, long pipelines with significant pressure loss, and supply systems with tanks located at high elevation. Suitable for agricultural and livestock operations, estates, and off-grid homes that require high pressure with sustained flow.

Technical Specifications

Compatibilities

Accessories: 1¼” check valve, submersible cable, waterproof joints, level probe, DC type II protections, AC circuit breaker, IP65 panel, and PV structure/cabling. PV recommendation: size a minimum indicative power ≥ 1200 W according to required head/flow and always respecting the MPPT range.

The ZIRI 4SC3-185 3CV combines high pressure, consistent flow, and integrated electronics with AC backup option, providing reliability and efficiency in demanding solar pumping projects.
