Blue Sky Energy Charge Controllers

Blue Sky Energy Solar Boost Charge Controllers

The Blue Sky Solar Boost charge controllers feature Maximum Power Point Tracking (MPPT), reverse-polarity protection, selectable charge voltage set points, and an equalize function. An optional user-friendly digital display is available to monitor PV charge performance. The display shows battery voltage, solar current, charge current, and charge mode, either in the controller, as a remote panel installed up to 300' away, or both. Optional temperature sensor provides for compensation of charge voltage to further improve charge controller and battery performance. Solar Boost controllers are available with or without the digital display and optional remote display. 5-year limited warranty.

Solar Boost 3024iL
 

The SB3024iL is designed to charge 12 and 24 DC battery systems from a 24 VDC array (maximum open-circuit voltage is 57 VDC). Maximum charge current is 40 A output at 12 VDC and 30 A at 24 VDC. It has an auxiliary output that can serve as a 20 A load controller or as a 2 A battery charger. The SB3024DiL version adds a front-mounted digital display.

The DUO-Option software upgrade converts the auxiliary output into a 20 A diversion type PWM charge controller. The DUO-Option upgrade allows a 3024 to provide charge control for hydroelectric, wind or similar DC generators requiring diversion type charge control while at the same time providing MPPT type PV charge control. The MPPT PV power controller and the diversion power controller operate as a single coordinated charge control system fed by multiple power sources. Operation is similar to the coordinated operation of multiple 3024’s on Blue Sky Energy’s IPN Network. This coordinated approach provides better battery charge control for hybrid systems compared to using a separate diversion charge controller. For dump load applications exceeding 20 A, the Current Booster Module CBM4070 will support dump loads up to 40 A. The CBM4070 is driven by the auxiliary output of a DUO-Option equipped 3024.

The SB3024 controllers are IPN network interface enabled, and include load-control outputs so they can also serve as lighting controllers. An IPNPro remote is required to enable and configure dusk-to-dawn lighting control. Listed to UL 1741 and CSA STD E335-1/2E.

Solar Boost 2512i-HV and 2512iX-HV, and 1524iX

The SB 2512i-HV is a fully automatic three-stage charge controller system. A partial IPN network interface is also included to allow use of the Universal Communication Module (UCM), and IPN-Remote and IPN-ProRemote displays. This controller is rated for 25 A maximum output with a 36-cell module, and 20 A with a 60-cell module. 

 The Solar Boost SB2512iX-HV and SB1524iX provide additional features including automatic or manual equalization, remote battery-temperature sensor input, full IPN network compatibility, and an auxiliary output. The user-configurable auxiliary output can serve as either a 25 A (15/20 in 1524iX) load controller or a 2 A auxiliary battery charger for a separate battery, such as the starter battery in an RV. The auxiliary output can also provide fully-adjustable dusk-to-dawn lighting control.

All three of these Solar Boost charge controllers can charge a 12 VDC battery from a single 60-cell module or by using 36-cell modules. The 1524iX can be used for 24 VDC systems, however two 36-cell modules in series, or a 72-cell module should be used in 24 VDC systems with this controller.
