2025 Flow Pro+ 12W | MPPT Solar Aerator System with Battery Backup
The Flow Pro+ is a powerful, professional-grade solar aeration system designed for large ponds up to 5,000 gallons. With an industry-leading 12W MPPT-optimised solar panel and 4000mAh LiFePO4 battery backup, it delivers up to 10 LPM of oxygenation through your choice of a 5-stone multi-zone system or a high-efficiency cylinder diffuser.
✓ 12W Solar Panel✓ 10 LPM Output✓ 5 Air Outlets✓ Cylinder Option✓ For Ponds to 22,730L✓ MPPT Technology✓ Free 24 Hour UK Delivery
Choose the configuration that suits your pond layout: multi-point stone aeration for wide coverage, or a deep-water cylinder for powerful single-zone delivery. Both provide the same total performance.
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.

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
