Patented Maximum Power Point Tracking (MPPT) technology allows Solar Boost SB50DL to increase charge current up to 30% or more compared to conventional charge controllers. 

Solar Boost SB50DL provides an advanced fully automatic 3-stage charge control system to ensure the battery is properly and fully charged, resulting in enhanced battery performance with less maintenance. An automatic or manual equalize function is also provided to periodically condition Flooded lead-acid batteries. To further enhance versatility, a user configurable auxiliary output and Blue Sky Energys advanced IPN network interface are
also included.

The user configurable auxiliary output can serve as either a 20 amp load controller, or as a 2 amp auxiliary battery charger. The load control feature can be used to limit excessive battery discharge in unattended remote systems, whereas the auxiliary battery charge feature is ideal for charging a separate battery such as the engine battery in an RV. The auxiliary output can also provide fully adjustable dusk to dawn lighting control.

Blue Sky Energys advanced Integrated PowerNet, or IPN Network, allows up to 8 IPN capable charge controllers to
communicate with each other and operate as a single machine rather than separate charge controllers. The IPN network also allows networked controllers to share an optional battery temperature sensor and remote display. The IPN network does not require a display or other special communication hardware to operate.


Patented MPPT technology increases charge current by up to 30% or more!
