Product Overview
SD-2 Solar Direct Aerator Single Panel
The SD-2 Solar Direct Aerator Single Panel system brings professional-grade, off-grid solar pond aeration to larger ponds without batteries, trenching, monthly electric cost, or AC power at the shoreline.
Built for ponds and small lakes where utility power is unavailable, impractical, or expensive to install, the SD-2 converts solar energy directly into three-phase power to run a brushless rocking piston compressor. The result is a rugged, efficient, low-maintenance solar pond aerator that operates during daylight hours and helps improve water quality where conventional electric aeration is difficult to justify.
The SD-2 is a strong fit for remote ponds, farm ponds, wildlife ponds, livestock water, HOA ponds, golf course ponds, irrigation ponds, parks, camps, and other off-grid water-quality applications. By delivering subsurface aeration through two DB-36 stainless steel diffusers, the system helps increase dissolved oxygen, reduce thermal stratification, improve circulation, reduce odor, support fish health, and encourage natural biological breakdown of organic matter.
Solar Direct Power, Fewer Maintenance Items
The SD-Series platform is designed to use solar power directly instead of storing it in batteries first. Eliminating batteries reduces up-front cost, reduces maintenance, improves conversion efficiency, and removes one of the most common long-term service items found in many solar aeration systems.
The SD-2 uses a high-efficiency digital motor-control platform and a solar module sized to provide strong compressor output in normal sun while still supporting operation in lower-light conditions. For sites that need even more runtime in very cloudy weather, rain, snow, or winter conditions, a second solar module can be added for dramatically improved low-light performance.
Built Around Durable, Serviceable Components
The SD-2 uses a 3-phase brushless rocking piston compressor, a rugged powder-coated welded steel enclosure, stainless steel hardware, active compressor cooling, over-pressure protection, individual circuit protection, replaceable intake filter/silencer cartridge, brass valves and fittings, and USSM DB-36 stainless steel diffusers. It is built for real outdoor use, not light-duty garden-pond service.
The SD-2 Single Panel kit includes:
- Complete compressor and control system
- One USA-made 60-cell mono-crystalline solar module
- Adjustable top-of-pole solar mounting system
- Pole-mount enclosure with mounting hardware
- Two DB-36 stainless steel diffusers
- One 300-foot reel of 3/8-inch weighted airline
- PV cables and required wiring components
- Easy-to-follow installation instructions
- US-based technical support
- Factory warranty coverage
The customer supplies a 3-inch Schedule 40 or Schedule 80 steel mounting pole with a 3.5-inch outside diameter. Do not use plastic pipe or tubing for the solar mounting pole.
Single panel or dual panel? The single-panel SD-2 is a cost-effective solar-direct aerator for normal sunlight conditions. Choose the dual-panel configuration when longer daily runtime, better low-light operation, winter performance, or additional operating margin is important.
