Keeps medium to large ponds oxygenated with 3 LPM airflow through dual stones, powered by a 6W panel with MPPT battery backup that runs through cloud and into evening.
Set the aerator up by placing the pump where it can stay out of silt and running each hose to an air stone positioned in separate pond zones. Keep the panel clean and in full direct sunlight, and adjust its position if shade or seasonal sun angles change.

A 6W high-efficiency solar panel charges an integrated LiFe battery, while MPPT power management helps optimise charging and output when sunlight conditions change.
MPPT Technology – Features and Benefits
PowerBee Ltd introduces garden solar pumps with Maximum Power Point Tracking (MPPT) technology. 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.
MPPT solar air pump – maximum efficiency for aeration systems
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.
Reliable functionality throughout the day and night.
Innovative Technology, Industry First
First to bring MPPT technology to garden and pond solar systems.
Designed for solar pumps, oxygenators, and fountains of all sizes.
Sets a new standard for efficiency and performance in the industry.
Dual-Stone Aeration for Wider Coverage
Two air stones help spread aeration more evenly across the pond. Position the stones in separate areas to improve circulation and support oxygen transfer where fish tend to gather in warm conditions.

Pond Size & Stocking Guide
Use this guide to estimate suitability based on pond size and typical fish load. For deeper ponds, waterfalls or heavy stocking, consider adding additional aeration.
Pond Category
Capacity
Typical Stocking
Recommendation
Medium Ponds
4500–9000 L
Goldfish or mixed stocking
Dual stones provide strong coverage
Large Ponds
9000–13,500 L
Koi or warmer summer conditions
Use dual stones, optimise placement
Extra Large
13,500 L+
Heavy stocking or high demand
Consider multiple units
Optimisation Tips
Small placement adjustments can make a noticeable difference to daily output. Focus on sunlight exposure and stone positioning.
Stone Placement
Place stones in separate pond zones
Avoid burying stones in heavy silt
Keep hoses clear of sharp edges
Panel Position
Mount panel in full direct sunlight
Avoid shade during peak hours
Adjust angle as seasons change
Routine Care
Wipe panel clean when dusty
Inspect hoses for kinks or splits
Clean stones if airflow reduces
Premium Aeration, Low Running Costs
Built for seasonal pond demand, this 6W dual-stone aerator combines strong airflow, battery backup and MPPT optimisation to support healthier pond conditions without mains power costs.
I had previously bought a cheap and less than cheerful Solar Air Pump from elsewhere (which had stopped working in less than a year). I decided to risk spending a bit more for this kit and I'm so glad I did. Feels like quality straight out of the box and went together quickly and easily. Even on a late Autumn day the solar panel has been chugging away and the bubbles keep on flowing. Very happy with my purchase and hope it lasts longer than the last.
Very impressed.
I've had it a month now. Despite the short, cloudy days here in the north of England it's been working every day. Output is good and it was a piece of cake to install. I'm a very happy customer!
Excellent solar air pump
I am going to be honest with you I don’t really know that much about fish we got a few small Koi, we have had them for around four years and we never bothered with anything about oxygen before we have a few plants in the pond and thought that was enough, an old school friend came to visit me who is an expert and told me that I needed to put some oxygen into my water otherwise I risk having something called Fishkill which sounds horrendous and terrible we can’t really afford mains because it costs an absolute fortune to install a plug down near the pond which is about 40 feet away so I opted for solar power, this kit looked very good and semi-professional it was certainly the best oxygenator we could find started working straightaway after we installed it pumping out oxygen into the pond we also added a few more oxygenating plants and the fish seem a lot happier, I do feel a lot happier alsi now I reckon I should do little bit more research about Koi As when they get bigger they obviously need more oxygen from the water and if the pond is not big enough the oxygen will deplete apparently so you almost have to add something to add the oxygen back in, everyone should know about this because it really worried me, But I am very happy with this solar powered air pump it’s a very good bit of kit very well-made and works well and I would recommend it
