Overview
Solar cascade pump with 1800 LPH max flow and 3.5m max head, supplied with a 40W monocrystalline solar panel.
Use this solar cascade pump by routing water through compatible 19 mm tubing (sold separately) and positioning the pump to minimise lift for your chosen waterfall or circulation layout.
Designed for versatility, it works seamlessly with medium to large ponds for various water features.

Exclusive MPPT Technology – Developed for Solar Pond Pumps
PowerBee Ltd was the first company to introduce MPPT-managed control systems into small garden and pond solar pumps — a level of solar optimisation previously used mainly in larger-scale applications.
Our MPPT design helps improve energy conversion in variable light, supporting more consistent flow and stronger usable performance in real UK conditions.
How Can I Create Stunning Waterfalls While Enhancing Pond Health?
The Max Head 3.5m system is ideal for producing natural-looking cascading waterfalls while improving pond circulation and oxygenation.
Cascade Waterfall Guidance
Why Cascading Waterfalls Work So Well
Waterfalls enhance visual appeal while breaking surface tension, promoting oxygen exchange and helping prevent stagnant water conditions.
Using the Pump for Cascade Effects
Attachments: Use compatible 19 mm tubing to route water.
Placement: Position the pump to minimise unnecessary lift.
Outlet Design: Delivers a steady, controlled flow.
Adjustment: Fine-tune flow to suit your waterfall design.
Additional Applications
Suitable for cascades, jet sprays, spitters, and circulation.
Optional battery improves consistency in variable light.
Durable construction for long-term outdoor use.
Note: This solar pump is an eco-friendly solution designed to enhance both water movement and overall pond health.
Powerful 1800 LPH Multi-Use Pump
The Cascade Pump Max Head 3.5 is a premium panel-to-pump kit built for waterfalls, cascades, and general water circulation.
Key Capabilities
Performance & Control
High-volume circulation for medium to large ponds
3.5m maximum lift for strong waterfall effects
Adjustable flow control
Protection & Efficiency
Dry-run and rotor-lock protection
40W monocrystalline solar operation
MPPT support when paired with battery backup
Performance Flow Rates
The 40W system delivers strong water movement in direct sunlight. Battery backup reduces peak flow slightly to extend runtime.

Performance note: Flow rates are measured under optimal sunlight. Battery backup extends runtime but reduces peak output by around 30%. For best waterfall results, aim to operate at least 0.5 m below the maximum lift height.
Optional Battery System (Recommended)
Adding a battery backup provides smoother, more consistent operation during cloud cover and evening hours.
Reduces start-stop behaviour
Extends operating time
Improves visual consistency of cascades

Tip: Position solar panels facing south at roughly 30–45° for best daily performance.
Our pump systems are designed for efficient, year-round operation, delivering best performance during spring and summer. Follow this guide for proper setup, seasonal adjustments, and maintenance to maximize performance and product life.
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
