Powers medium to large waterfalls with 3500 LPH flow and a 3.1m max head from twin 35W panels, with an MPPT controller and optional 12Ah LiFePO4 battery for extended running.
Use the pump and panel together with your chosen tubing layout, positioning the components to match the lift and circulation path you want to create. It’s intended for pond circulation and waterfall-style water movement, with direct solar operation and the option to add a battery backup depending on when you want it to run.

Transform Your Pond's Ecosystem
With its powerful 3500 LPH flow capacity and up to 3.1 meter head height (solar mode), this system moves water more effectively than standard fountain pumps. The high-volume flow creates natural circulation patterns that improve both visual appeal and aquatic health.
Oxygenation & Water Quality
Breaks surface tension for optimal gas exchange
Distributes oxygen evenly through the water column
Prevents thermal stratification in deep ponds
Reduces stagnant zones that encourage algae
Installation Flexibility
Side-mounted for circular current patterns
Sub-surface angled placement for surface agitation
25 / 32 / 38 mm tubing ready for waterfall creations
5m cable allows optimal solar panel positioning
Precision Water Movement Engineering
The system’s dual 35W polycrystalline solar panels (approx. 80W total output) deliver consistent power to move 3500 liters per hour at low elevations, maintaining strong flow even at the maximum 3.1 meter solar head height – perfect for:
Cascade & Waterfall Creation
Build multi-tiered cascades up to 3.1m high (solar)
Create dramatic waterfall features
Design natural stream flows
Pond Circulation Systems
Complete water turnover every 2–3 hours
Eliminates dead zones in pond corners
Uniform temperature distribution
Creates optimal conditions for aquatic life
Professional-Grade Components
This system combines commercial-grade solar technology with industrial water movement engineering. The panels deliver reliable solar power to the high-efficiency DC brushless pump, while dry-run protection and robust construction ensure long service life. Every component is designed for continuous outdoor operation and easy integration into existing pond ecosystems.
Proper sizing ensures your water movement system works effectively without being overpowering. As a general principle, aim for complete water turnover every 1–2 hours for optimal oxygenation and circulation. The 3500 LPH solar capacity suits ponds between 1,000–3,000 liters for circulation, or smaller volumes when creating waterfalls.
Ornamental Ponds
500–1000L: Turnover every 10–20 minutes
1000–2000L: Turnover every 30–40 minutes
2000–3000L: Effective for medium fish stocks
Waterfall Systems
0–1m height: 2500–3500 LPH flow
1–2m height: 1500–2500 LPH flow
2–3m height: 500–1500 LPH flow

Discover the operational principles and realistic performance expectations of your
energy-efficient water pump system throughout the seasons. This guide helps you
understand your system's capabilities and how to maximize its potential.
1. Operating Principles
Energy Collection
The panel captures sunlight and converts it to electrical energy
Energy powers the pump directly or charges the battery (in backup models)
System activation depends on light intensity and system type
Performance varies significantly with weather conditions
System Types
Direct Systems: Function only with sufficient direct sunlight
Battery-Backed Systems: Store energy for more consistent operation
Hybrid Systems: Combine immediate operation with energy storage
Each type offers different benefits based on your specific needs
2. Realistic Performance Expectations
Direct Systems Performance
Operation strictly dependent on available sunlight
Flow varies continuously with passing clouds
May start and stop multiple times on partly cloudy days
Strongest performance during midday hours with direct sun
No operation during evening or heavily overcast conditions
Battery-Backed Systems Performance
More consistent operation throughout the day
Continues running during brief cloudy periods
Provides operation after sunset (typically 1–8 hours depending on model)
Maintains steadier flow rate regardless of minor light variations
May include adjustable flow settings and timer functions
3. Seasonal Performance
Summer Performance (May to August)
Peak performance period for all system types
Direct Systems: Operation possible from early morning to evening on clear days
Battery Systems: Consistent daytime operation plus evening hours
Maximum flow rates achieved during direct midday sun
