The SE 2000 pump pushes 1400 litres per hour through a 20-litre filter bucket, keeping your pond clear and well-circulated without mains power. The LiFePO4 battery stores energy throughout the day so the system keeps running through cloud and into the evening — up to 14.5 hours on a sunny day. Add the optional 5W UV clarifier to kill green algae at the source.
The SE 2000 is one of our most popular pond pumps — proven across thousands of installations. Paired with the MPPT battery controller, it charges faster and runs longer than standard solar pumps.

Filtration & Water Clarity
The 20-litre SPF-20 filter bucket is three times larger than the standard eco filters included with smaller kits. More filter volume means longer intervals between cleaning and better water quality.
20L Filter Bucket
20-litre capacity — 3x standard eco
Dual mechanical filter pads
2x mesh media bags (media optional)
Pump pushes water through the bucket
No need to elevate — sits at pond level
Optional: UV Clarifier (+£59.99)
5W LED UVC kills green algae
Destroys bacteria and viruses
Connects inline: pump → UV → filter
Powered from battery box (12V DC)
19→25mm adapter included
Suitable Ponds
Wildlife ponds up to 2,000 litres
Fish ponds up to 1,500 litres
Koi ponds — light stocking only
Raised and in-ground ponds
Preformed liners and flexible liners
How It Works
The pump sits submerged in the pond and pushes water through the filter bucket. The solar panel charges the battery during daylight, and the battery keeps the system running through cloud and into the evening.
Set up your solar pond filter system in under 30 minutes. No mains wiring, no plumber — just solar power and clean water.
Important Setup Notes
⚠️ Before first use, allow the solar panel to charge the battery for 24–48 hours in direct sunlight. This ensures maximum battery capacity and reliable operation. For winter storage, fully charge the battery, then disconnect all cables and store pump and battery indoors in a frost-free environment.
1. Position the Filter Bucket
Place the SPF-20 filter bucket at the pond edge. It can sit at pond level — no need to elevate it. The pump pushes water through the bucket and out the other side back into the pond. Ensure the return outlet points back towards the pond.
2. Install the Pump
Place the SE 2000 pump in the pond, fully submerged. Use the included float for deeper water. Connect 19mm tubing from the pump outlet to the filter bucket inlet. Adjust the flow dial to balance filtration with water movement.
3. Set Up the Solar Panel & Battery
Position the 40W panel in the best available sunlight — ideally south-facing. Use the ground spike to secure it. Connect the panel to the battery controller. Connect the pump cable and fountain light cable to the battery box. Allow 24–48 hours initial charging.
4. Optional: Add UV Clarifier
If you’ve added the UV option, connect the clarifier inline between the pump and filter bucket using the included 19→25mm adapter. Plug the UV power cable into the light output on the battery box (12V DC). The UV draws just 5W — minimal impact on battery life.
5. First Start & Settling
Once the battery has an initial charge, press the power button on the battery controller. Check for leaks at all hose connections. Water may appear slightly cloudy initially — this is normal. The filter pads will begin trapping debris immediately. Allow 2–4 weeks for the full biological cycle to establish.
6. Routine Maintenance
Rinse filter pads in a bucket of pond water every 2–4 weeks (never tap water — chlorine kills beneficial bacteria). Clean the pump impeller if flow reduces. Top up pond water in hot weather. Clean the solar panel with a soft cloth. In winter, fully charge the battery, drain the pump, and store both indoors.
Our pump systems are designed for efficient, year-round operation, but perform best during spring and summer. Follow this guide for proper setup, seasonal adjustments, and maintenance to maximize performance and longevity.
