Overview
Solar pond filter system with 1400 LPH pump and 40 W solar panel for fish ponds up to 2000 litres, with optional MPPT battery backup.
Set the system up by positioning the solar panel where it can receive direct sunlight and placing the integrated pump and filter so water can circulate through the filtration stages. It uses a DC brushless pump with dry-run protection and adjustable flow control, and selected configurations support an optional MPPT battery backup for operation when light levels drop.

Solar Power & Filtration System
The system uses a 40 W solar panel to power an integrated DC brushless pump, delivering steady circulation for filtration. Mechanical and biological filtration stages work together to remove debris and support a balanced pond environment.
Solar Panel
High-efficiency polycrystalline panel designed for outdoor use and consistent energy capture in suitable sunlight.
Filter Media Options
Compatible with zeolite or gravel media to support biological filtration and water clarity.
System Flexibility
Suitable for pond filtration, circulation, and decorative applications where flow and head height requirements are met.
MPPT Battery Backup (Optional)
Selected configurations support an optional MPPT battery backup system. Energy collected during sunny periods can be stored and used when light levels drop, helping to stabilise system operation during changing conditions.
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.
Foam filter stages capture solid debris, reducing waste build-up within the pond.
Biological Filtration
Filter media encourage beneficial bacteria that help convert waste products into less harmful compounds.
Performance Characteristics
When correctly installed, the system provides a maximum flow rate of up to 1800 litres per hour in direct solar operation, or up to 1400 litres per hour when running in battery mode. Maximum pumping head is up to 2.0 metres in direct solar conditions. Actual performance will vary depending on sunlight, installation height, and system configuration.
