Large Solar Pond Filter System – High-Capacity Filtration for Fish Ponds
This large solar pond filter system is designed for higher-volume ponds that require stronger circulation and more advanced filtration. Combining a high-output 80W MPPT solar pump with a multi-stage filter box, the system supports clearer, healthier pond water in medium to large garden ponds without relying on mains electricity.
✓ Up to 2800 LPH Flow Rate✓ For Ponds up to 8000 L*✓ Multi-Stage Filtration✓ Optional UVC Clarifier✓ MPPT Solar Efficiency✓ Battery Options Available
As with all solar-powered filtration systems, output depends on sunlight availability. Best performance is achieved in direct sunlight, with reduced output during prolonged overcast conditions or outside peak summer months.

Pond Suitability
Pond Size
Suitable for medium to large ponds when correctly sized and stocked.
No fish: up to 8000 L
Light fish stock: up to 5000 L
Heavier stock: additional filtration advised
Sunlight Requirements
Designed for solar operation using high-efficiency MPPT control. Performance varies with weather, season, and panel placement.
Water Features
Supports circulation, waterfalls, and return flows where pumping height requirements are within system limits.
Filtration System Design
The filter box uses multiple filtration stages to manage both visible debris and dissolved waste. Mechanical filtration removes solids, while biological media supports beneficial bacteria that help maintain balanced pond conditions.
Mechanical Filtration
Brush elements and layered foam filters capture leaves, sludge, and suspended debris before water returns to the pond.
Biological Filtration
Ceramic biomedia supports bacterial growth to help break down fish waste and organic matter naturally.
Maintenance Access
Large filter chamber with removable components for straightforward cleaning and seasonal servicing.
UVC Clarifier Option
This system is available with or without an integrated UVC clarifier. The UVC version helps reduce green water algae by sterilising free-floating algae as water passes through the filter chamber.
UVC wavelength: 265–315 nm
Lamp power: 5 W
Helps improve water clarity
Important: When the UVC option is selected, a battery system is required to power the UVC lamp via the light output on the MPPT battery controller.
Solar Pump & MPPT Power System
The system is powered by an 80W solar pump configuration using MPPT (Maximum Power Point Tracking) technology. MPPT continuously adjusts power input to maximise usable energy from available sunlight, improving real-world performance in changing conditions.

Exclusive Revolutionary MPPT Technology - Features and Benefits
PowerBee Ltd proudly introduces the world's first garden solar pumps with Maximum Power Point Tracking (MPPT) technology - a breakthrough previously only available in industrial solar systems. The battery for this pump includes our own patent pending MPPT system, which automatically optimizes solar energy conversion to deliver 30% more efficiency than conventional solar pumps, ensuring stronger performance in all weather conditions.
Exclusive MPPT optimisation for maximum efficiency
Advanced Solar Optimization > 30%
Maximum Power Point Tracking (MPPT) ensures peak efficiency in all weather conditions.
Up to 30% higher energy conversion compared to standard solar systems.
Optimized performance even during (in season) cloudier or lower-light periods.
Extended Performance and Reliability
Faster battery charging for uninterrupted operation.
Extended operating hours for pumps, aerators, and fountains.

Performance and runtime vary with sunlight, season, and installation.
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
