Import 2.2kw Solar Water Pump System For Irrigation — Buy in Bulk from Supplier in China

This 2.2kW solar-powered water pump system from Guangzhou Nianguan Electronics Technology is engineered for agricultural irrigation, pasture watering, and water supply projects where grid electricity is unavailable or unreliable. The system integrates a photovoltaic array, a submersible or surface pump, and a dedicated solar pumping inverter that uses dynamic VI maximum power point tracking (MPPT) to optimise energy harvest under changing sunlight conditions. Rather than storing energy in batteries, the design philosophy prioritises pumping water into a reservoir during daylight, which reduces system complexity and long-term maintenance costs.

The inverter is built around an intelligent power module (IPM) with reported efficiency of 98%, housed in an aluminium-alloy enclosure rated to IP41 for dust and water-splash protection. Operating temperature range is -10°C to +50°C, and the unit includes a 43 × 29 mm LCD panel for parameter setup. Protective functions cover overload, over-voltage, under-voltage, over-temperature, reverse polarity, lightning surge, over-flow, and dry-running conditions. An optional city-power bypass connection allows the pump to continue operating during prolonged overcast periods, a feature worth confirming with the supplier for off-grid sites that require round-the-clock water delivery.

Buyers in arid and semi-arid regions, including parts of Africa, the Middle East, and Central Asia, source these systems for drip-irrigation schemes, livestock watering stations, and desert-reclamation projects. Municipal buyers also deploy similar arrays for park fountains and landscape water features. Because the supplier's listing does not specify pump head, flow rate, solar panel wattage, or minimum order quantity, importers should request a complete technical datasheet and a quotation that includes shipping terms (FOB Guangzhou or CIF to destination port) before committing to a purchase order.

Guangzhou Nianguan Electronics Technology Co., Ltd. is registered at R326, Floor 3, Jin Fu Building, No. 90 Qifu Road, Guangzhou 510810, Guangdong, China. The company is listed as an imported-tier supplier on the marketplace, though its current response rate is shown as 0% with no recorded average response time, which means prospective buyers should allow extra lead time for initial correspondence or reach out through the Skype handle (gznianguansales) or email address provided in the product description.

The listing focuses exclusively on solar pumping systems and does not disclose the company's founding year, employee headcount, export history, or third-party certifications. The product description demonstrates familiarity with inverter design, MPPT algorithms, and IPM circuit topology, suggesting an engineering-oriented firm rather than a pure trading company. Buyers should request copies of any CE, IEC 62109, or ISO certifications, as well as factory audit reports, before placing volume orders.
