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.
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.

system is built for wide ponds, deeper zones, and heavier stocking where
consistent oxygen levels support healthier water conditions.
Airflow Capacity
10 LPM total airflow output
500 mmHg max pressure
5-outlet or cylinder diffuser setup
Designed for large pond circulation
Solar + Battery Behaviour
12W polycrystalline solar panel
MPPT control (up to 30% boost)
LiFePO4 Battery: 12.8V 4000mAh
Backup runtime up to 17 hours
Protection & Safety
Locked rotor + overload protection
Reverse polarity safety system
IP65 weather protection housing
Certified CE / UKCA / RoHS
Choose Your Diffuser Configuration
Both options deliver the same total airflow output. The difference is how
oxygen is distributed across the pond.
5-Stone Multi-Zone Setup
Five independent air outlets
Best for wide or irregular ponds
Even oxygen distribution
Ideal for koi and mixed stocking
High-Efficiency Cylinder Diffuser
Single deep-water outlet design
Strong vertical oxygen lift
Best for deeper ponds (4ft+)
Focused zone oxygenation
Pond Size & Application Guide
This 12W aerator is designed for larger ponds where higher oxygen demand
requires stronger airflow and longer daily runtime.

Professional Aeration for Large Ponds
With strong 10 LPM airflow, MPPT-supported charging, and extended Battery
runtime, this 12W system is ideal for pondkeepers needing dependable
oxygenation across larger volumes of water.
We have been using our pond oxygenator since April 2020 and cannot recommend it highly enough. Works right through the year and happily bubbles away even on days with light cloud. Had previously tried several different units from other companies and been highly disappointed. Would definitely buy again.

Easily assembled. Bought because our pond (3m x 2m) was opaque green. Within a week the water is clearer. Admit to being surprised that one small inexpensive oxygenator can make such a big difference
