Battery Backup Unit Upgrade Kit for existing Solar-Direct Systems

Do you already have an SD-Series Solar-Direct Aerator?  If so, this package allows you to upgrade your existing system to a Battery Backup System.

The package includes:

• Enclosure
• 4 Batteries
• All Cables & Connectors
• Smart Controller with Digital Timer
• MPPT Charge Controller
• Low Voltage Disconnect
• Complete Instructions
• Full Tech Support
• Solar Panel and upgrade hardware (Optional, if needed)

IMPORTANT:

The BBU Upgrade requires 2 solar panels.  If your existing SD-Series aerator is currently configured with a single solar panel, you'll need to select the 2nd panel option.  Please CONTACT US or call (608)272-3999 if you have any questions about this.

Just like our full Battery Backup Systems, the BBU Upgrade Kits include the following:

• 48-Volt System with 4 AGM Batteries:
  Our aerator is the only system on the market to use 48-volt technology, paired with 4 AGM batteries for extended backup and higher efficiency. Most competitors only offer 2 batteries, limiting runtime and performance. With our system, you get more power and longer operation—even during the most challenging weather conditions.

• The Only Retrofit Solution for Existing Solar-Direct Systems:
  We are the only company offering a system that can be retrofitted to our existing Solar-Direct units. If you already own one of our Solar-Direct aerators, you can easily add our Battery Backup System to your setup. You can also install a Solar-Direct system now and add the battery backup later—providing the ultimate in flexibility and value.

• Proprietary Smart Controller:
  Our Smart Controller is the heart of your system, offering digital Time Clock functionality for precise control over run schedules. In addition, it actively controls the cooling fan operation, helping extend the life of your fan and improve battery longevity, especially during cold weather. This intelligent system ensures your aerator runs smoothly year-round.

• Optional Slow-Start Controller:
  Our Slow-Start controller is a game-changer. For the first time, you can start your aeration system gradually over a two-week period, avoiding the risk of fish kill. This unique feature gives you peace of mind, knowing your aquatic life will stay healthy while your system powers up.

• Industrial-Style Control Section with Full Wire Management:
  Designed with industrial-grade functionality, our system includes fully organized wire management that keeps your installation clean, efficient, and safe. The professional-grade control section ensures everything runs as it should, with minimal maintenance required.

• Magnetic Air Intake Louver – Quick and Easy Maintenance:
  We’re proud to offer the only magnetic air intake louver in the industry. This easy-to-use design lets you inspect, clean, and reinstall the louver in seconds—no tools required. No more complicated maintenance procedures—just quick, efficient upkeep for maximum system performance.

• Locking Enclosure Hardware
• Durable Powder Coat Finish
