The Sunpal Solar Waterpump System is a solar‑powered water pumping solution designed for agriculture, irrigation, residential and commercial water supply. It harnesses solar panels and an inverter to run permanent magnet AC pumps for off‑grid or remote sites where sunlight is available.
Models: SP5HP-AC, SP10HP-AC, SP20HP-AC. Included per model: 280W mono panels (20 / 40 / 80 pcs), DC disconnect switches (1 / 2 / 5), solar pumping inverter (1 × 5.5 / 7.5 / 15 kW), solar pump (1 × 3.7 / 5.5 / 13 kW), DC cable (100 / 200 / 500 m), MC4 connector pairs (4 / 8 / 20), water level switch (1), ground mounting system and PV tools.
Standard panel: 280W mono, 60 cells. Vmp 31.8 V, Imp 8.81 A, Voc 38.8 V, Isc 9.33 A. Dimensions: 1650 × 992 × 35 mm. Weight: 18.6 kg.
Inverter power options: 5.5 kW, 7.5 kW and 15 kW. Max DC input voltage: 850 V. MPPT operating voltage range: 500–700 VDC. Warranty: 3 years standard. Wi‑Fi stick, LAN and GPRS are available as options for monitoring.
Because Vmp is 31.8 V per panel, you typically need about 16 panels in series to reach ~500 V and about 22 panels for ~700 V (500/31.8 ≈ 15.7; 700/31.8 ≈ 22.0). Do not exceed the inverter max DC input of 850 V (≈26 panels max in series). Final string design should be confirmed by an installer.
Approximate daily flows and head ranges by system: SP5HP-AC: 10–20 m³/day with pump head ~145–90 m. SP10HP-AC: 80–160 m³/day with head ~79–43 m. SP20HP-AC: 700–1100 m³/day with head ~22–18 m. Actual output depends on site solar irradiance and system configuration.
Pumps are permanent magnet AC with bodies in AISI 304 stainless steel. Outlet diameters: 1" (30 mm), 1¼" (65 mm), 2½" (150 mm) depending on model. Pump enclosure rating: IP68. Suitable for submerged/well and tank applications.
Yes. Each system includes a water level switch for dry‑run protection in wells and overflow protection for tanks. The switch is fast‑response, compact and designed for long life.
Standard DC cable supplied is 4 mm² (6 mm² optional). Rated voltage: 600 VDC (UL) / 1000 VDC (TUV). Rated current: 55 A (4 mm²) / 70 A (6 mm²). MC4 connectors supplied per model (4/8/20 pairs). DC disconnect switch: 1000 VDC rated voltage, available in 16 A and 20 A options, IP66 rated, M20/M25/MC4 connections.
A ground mounting system is supplied for standard installations. Rails are aluminum AI6005 with SUS304 bolts, mid and end clamps in several sizes, L‑foot and asphalt/hanger bolt options, and optional cable clips, ground clips and lugs.
The system is a direct solar pumping solution (PV → inverter → AC pump) and does not include batteries. It operates when sufficient sunlight is available. For 24/7 operation or night pumping you would need to integrate energy storage or an alternate power source, which is not included by default.
Optional monitoring via a Wi‑Fi stick is available, and LAN or GPRS connectivity can be added for remote monitoring and data logging. The inverter supports these optional modules.
Standard warranty is 3 years for the system. Typical component lifetimes: solar panels and DC cables are rated for long service life (DC cable lifetime ≤ 25 years). Regular maintenance extends service life.
Recommended maintenance: clean panels periodically (dust/soiling), inspect and tight‑check electrical connections and MC4 connectors, check DC disconnect switch function, verify pump seal and wiring, and test water level switch. Visual inspections every 3–6 months and a professional service annually are typical.
