Don't throw your PV power away! With Maximum Power Point Tracking (MPPT) technology the SB 50DL w/ display Solar Boost helps you get the most for your money. The Solar Boost 50DL also provides the most advanced precision Multi-stage Pulse Width Modulation (PWM) charge control system to ensure the battery is properly and fully charged. This results in enhanced battery performance with less battery maintenance. An equalize function is also included to periodically condition liquid electrolyte lead-acid batteries. The Solar Boost 50 is so well designed that it would be a winner even without the MPPT function. The MPPT power converter can charge lower voltage batteries from higher voltage panels. For example It can accept a 24 volt PV array to charge a 12 volt battery bank. This reduces the array wiring to 1/4 the size. A built in LCD digital display monitors solar charge performance. The display shows battery voltage, solar panel current and output charge current. You can actually see current boost working by noting the difference between solar panel current and output charge current.Back to Top

About Blue Sky

Industry Leaders In Solar Boost™ Charge Controllers With Maximum Power Point Tracking (MPPT)

Blue Sky Energy, Inc. is a quality-driven, customer-oriented company. Their development of Maximum Power Point Tracking technology in 1998 led to the issuance of two patents. Their products are used worldwide to provide power in battery based or off-grid systems. Whether the system is a remote telecomm site, security camera, portable solar power system for the military, an RV or boat, Solar Boost products are selected because of their proven reliability, consistent quality and affordable prices. Blue Sky patented technology delivers up to 30% more power from your PV Modules than conventional solar charge controllers.

What is the IPN Network?

Blue Sky Energy created the Integrated Power Net™, or IPN Network to provide both a charge controller communication strategy as well as create the next generation of Solar Boost MPPT charge controllers. The advanced high speed digital 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 an additional controller, display or other special communication hardware or software to operate.
