Products Description
550W Solar Water Pump System – Complete Off-Grid Water Supply Solution
Solar-Powered Pump System for Agricultural & Residential Use
The 550W solar water pump system is a complete, self-contained water supply solution harnessing solar energy for efficient water transfer in off-grid locations. The system converts sunlight into electrical energy via PV panels, with a dedicated solar controller regulating power output to drive a 48V DC brushless pump motor, delivering water from sources such as wells, rivers, ponds, or storage tanks. Available in both surface and submersible configurations with durable construction, this 550W (0.75HP) system ensures reliable performance for irrigation, livestock watering, and residential water supply without reliance on grid electricity.
Technical Profiles & Materials
Maximum Power Point Tracking (MPPT) Technology – Integrated MPPT controller with >99% efficiency maximizes solar energy harvest by tracking the optimal voltage point of the PV array, ensuring the pump operates efficiently even under varying sunlight conditions. Soft-start protects the pump motor from current surges.
High-Performance DC Brushless Motor – Features a maintenance-free, quiet, and highly efficient brushless DC motor with permanent magnets. The 48V DC operation provides strong performance with low noise, reducing maintenance compared to traditional AC motor designs.
Durable Corrosion-Resistant Construction – Pumps feature stainless steel or cast iron construction with technopolymer impellers for long-lasting performance and reliability in various water conditions. Stainless steel variants offer enhanced durability for coastal or saline environments

Products Application
Agricultural & Farm Irrigation
Ideal for irrigating crops, orchards, and farms, the 550W pump can supply approximately 6 m³/h at 15–30m head, covering up to 0.59 hectares based on 5mm/day watering schedule. Solar panels allow placement in remote fields without grid access. The controller's MPPT technology ensures performance even on cloudy days, providing up to 10% flow during overcast conditions.
Livestock Watering & Off-Grid Supply
Perfect for providing clean water to livestock in remote pastures and off-grid homesteads. Surface pumps draw water from rivers, ponds, and shallow wells, while submersible models deliver from deep wells up to 42m depth. The system's automatic dry-run protection and tank-full shutoff function provide worry-free operation.
Residential & Garden Water Supply
Suitable for household water boosting, garden watering, and swimming pool circulation systems. With an outlet size up to 2", the pump delivers sufficient flow for domestic needs. Available in quiet DC brushless motor configuration, ideal for residential areas where noise is a concern.

FAQ
Q: Can this system work without batteries?
A:Yes, the solar pump system can operate directly from solar panels via the MPPT controller without battery storage. However, adding batteries increases reliability during low sunlight conditions. The system includes dry-run protection and automatic shutdown features for safe operation.
Q: How many 550W solar panels do I need for this pump?
A: For a standard 48V 550W pump, a configuration of 2×550W solar panels (total 1.1kW) is recommended to ensure optimal performance. The panels are connected in series to achieve the required voltage. For higher flow models like the 6 m³/h pump, a larger array (800W–1.1kW) may be required.
Q: What maintenance does this pump require?
A: The brushless DC motor is maintenance-free. The system requires very little routine care: periodic cleaning of solar panels, checking pump inlet for debris, and seasonal inspection of O-rings and seals. The stainless steel/technopolymer construction ensures corrosion resistance and long service life.
