Why Choose the 4SV?
This pump is a cost-effective, sustainable solution for areas with unreliable electricity. Its plug-and-play solar compatibility makes installation simple, while its heavy-duty build ensures years of trouble-free operation.
Direct Solar-Powered Water Extraction
The 4SV series represents a category of efficient, brushless DC submersible pumps specifically engineered to operate directly from solar panels (PV modules) or a DC power source, without the need for batteries or inverters. These pumps are a cornerstone technology for off-grid irrigation, livestock watering, remote village water supply, and fountain applications.
Core Concept & Operating Principle
Unlike conventional AC pumps that require grid power or a bulky inverter, the 4SV pump integrates a built-in Maximum Power Point Tracker (MPPT) or optimized controller. This intelligent electronics package allows it to directly convert variable DC power from solar panels into controlled motor output. It starts operating at a low sunlight threshold and adjusts its speed in real-time to match the available solar energy, maximizing water output throughout the day.
Key Features & Design
-
Pure Solar Direct Drive: Operates seamlessly by connecting solar panels directly to the pump. No batteries, charge controllers, or AC inverters are needed, simplifying the system and reducing upfront and maintenance costs.
-
High-Efficiency Brushless DC (BLDC) Motor: Provides superior reliability, longer lifespan (due to no brush wear), and higher energy conversion efficiency compared to traditional brushed motors.
-
Built-in Smart Controller (MPPT): The integrated controller constantly optimizes the match between the solar array’s power curve and the pump motor, extracting maximum available power especially during cloudy periods or early/late in the day.
-
Plug-and-Play Simplicity: Designed for easy installation. Typically involves connecting the correctly sized solar array (in series/parallel) to the pump’s cable, submerging it, and securing the delivery pipe.
-
Durable Construction: Housing is usually made of corrosion-resistant stainless steel (often AISI 304 or 316) or high-strength engineering plastics, making it suitable for deep wells, boreholes, and clean or slightly sandy water.
-
Dry Run Protection: Many advanced models include built-in sensors or algorithms to shut down the pump if the water level drops too low, preventing motor damage.
Typical “4SV” Model Specifications
(The “4” often refers to a 4-inch diameter, a standard size for boreholes, and “SV” may denote “Solar Version.”)
-
Voltage Range: Commonly designed for DC systems, e.g., 30V to 300V DC, allowing for flexible solar array configuration.
-
Power Range: Typically from 200 watts to 1500 watts of solar input power.
-
Head (Pressure) & Flow: Performance varies by model. Example ranges:
-
High-Head Models: For deep wells (e.g., up to 200+ meters head).
-
High-Flow Models: For shallow wells or surface water transfer (e.g., up to 20+ cubic meters per hour at lower head).
-
-
Application: Ideal for boreholes, deep wells, streams, ponds, and tanks.
Advantages of a Solar DC Submersible Pump 4SV
-
Low Operating Cost: Zero fuel cost and minimal electricity cost (sunlight is free).
-
Reliability & Low Maintenance: Fewer system components (no inverter, no batteries) mean fewer points of failure. The BLDC motor is inherently robust.
-
Environmentally Friendly: Zero emissions, silent operation, and fully renewable energy-powered.
-
Ideal for Remote Areas: Provides a sustainable water solution where grid power is unavailable or unreliable.
-
Automatic Operation: Starts at sunrise, runs all day at variable speed, and stops at sunset—fully autonomous.
Solar DC Submersible Pump 4SV System Design Considerations
-
Solar Array Sizing: The PV array must be correctly sized to meet the pump’s voltage and power requirements under local solar conditions.
-
Total Dynamic Head (TDH): This critical calculation (vertical lift + pipe friction loss) determines the required pump model and power.
-
Daily Water Demand: Sizing is based on the cubic meters of water needed per day, which influences pump flow rate and required solar array size.
Conclusion
The Solar DC Submersible Pump 4SV is a transformative technology for off-grid water access. It represents a simple, durable, and cost-effective solution that leverages solar energy directly to provide a vital resource. By eliminating the complexity and expense of energy storage, it offers a highly reliable means of irrigation, drinking water supply, and livestock management, empowering rural and agricultural communities with sustainable, solar-powered water independence
