Get dramatically improved performance from your solar modules and batteries with the Blue Sky 50DL charge controller.

Don't throw your PV power away! With Maximum Power Point Tracking (MPPT) technology the Solar Boost helps you get the most for your money. The Solar Boost 50DL also provides the most advanced precision Multi-stage Pulse Width Modification (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.
