Professional Solar Water Circulation System – 80W | 3500 LPH | 3.1m Head | Battery Backup Option
Engineered for optimal water movement in medium-to-large ponds, this high-performance solar pump creates healthy circulation patterns without electricity costs. Choose direct solar for maximum lift and flow, or add the optional LiFePO₄ battery backup for extended operation after sunset and in cloudy conditions. The included 38mm tubing enables professional waterfall and cascade installations.
✓ 3,500 LPH Powerful Flow (Solar) ✓ 2,800 LPH Flow (Battery) ✓ Max Head: 3.1 m Solar / 1.8 m Battery ✓ Professional 80W Solar System ✓ MPPT Technology Included ✓ Zero Running Costs
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.

Pond Sizing & Flow Recommendations
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
