The SB3000i charge controller, utilizing patented MPPT (Maximum Power Point Tracking) technology, is a compact, reliable, and fully programmable solution. It offers a range of features that make it well-suited for RVs, marine applications, PV street lighting, and small-scale off-grid electrification projects.

Compact and Reliable: The SB3000i is designed to be compact and dependable, making it suitable for various applications where space and reliability are essential.

Patented MPPT Technology: The charge controller incorporates patented MPPT technology, allowing it to efficiently track and maximize the power output of solar panels. This technology enhances the energy harvesting capability of the solar system.

Second Battery Output: The controller includes a second battery output, which is particularly beneficial for RVs and marine applications where multiple battery banks are utilized for various energy needs.

IPN Connection for Remote Display and Networking: The controller features an IPN connection that enables remote display and networking capabilities. This allows users to monitor and manage the charge controller's operation from a distance using devices like IPN ProRemote, ProTouch, or BT Connect.

Programmability: The SB3000i can be programmed either through its onboard display or in conjunction with compatible devices like IPN ProRemote, ProTouch, or BT Connect. This level of programmability offers maximum flexibility in tailoring the controller's operation to specific requirements.

Versatile Battery Compatibility: The controller is compatible with a range of battery types, including FLA (Flooded Lead Acid), AGM (Absorbent Glass Mat), Gel, and Lithium batteries. This compatibility ensures that the controller can be used with a variety of energy storage options.

IPN Network Interface: Similar to other Blue Sky Energy charge controllers, the SB3000i's IPN Network interface allows it to communicate with other Blue Sky Energy charge controllers as part of a single charging system. This feature enhances system design flexibility and optimization.

The SB3000i charge controller with MPPT technology is designed to provide compactness, reliability, and programmability for a range of applications. Its second battery output, IPN connection, and compatibility with various battery types make it versatile and adaptable to different energy setups. The ability to communicate with other charge controllers via the IPN Network interface further enhances its capabilities in system design and coordination.
