Manufacturer's Description

Patented Maximum Power Point Tracking technology allows Solar Boost 1524iX to increase charge current up to 30% or more compared to conventional charge controllers. Don't waste your money by throwing PV power away! Get the power you paid for with a Solar Boost charge controller.

Solar Boost 1524iX's advanced fully automatic 3-stage charge control system will properly charge flooded lead-acid, AGM and Gell batteriesk resulting in improved battery performance with less battery maintenance. The dual 15/20 amp rating will deliver up to 15 amps in 24 volt systems, or up to 20 amps in 12 volt systems. 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 Energy's advanced IPNTM network interface are also included.

The user configurable auxiliary output can serve as either a 15/20 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 start battery in a boat or RV. The auxiliary output can also provide fully adjustable dusk to dawn lighting control.

Blue Sky Energy's advanced Integrated Power NetTM, 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 hardware to operate.

  • 15 Amp 24 Volt and 20 Amp 12 Volt Rating Supports A Wide Range Of Applications
  • Optional IPN-ProRemote Display Provides Charge Control and Full-Featured Battery System Monitoring (NOT included)
  • 3-Stage Charge Control with Filtered PWM Output Improves Battery Performance and Life While Minimizing Battery Maintenance
  • Clear Anodized Faceplate, Galvanized Mounting Box and Conformal Coated Electronics Resist Corrosion
  • Automatic or Manual Equalization To Periodically Condition Flooded Lead-Acid Batteries
  • IPN Network Interface Coordinates Multiple Controllers and Shares Optional Battery Temperature Sensor and Display
  • Auxiliary Output Provides 15/20 Amp Load Control Or 2 Amp Auxiliary Battery Charge
  • Lighting Control Provides Separate Post-Dusk and Pre-Dawn timers
  • Full 5 Year Limited Warranty

Solar Boost controllers increase charge current by operating the PV module in a manner that allows the module to produce all the power it is capable of. A conventional charge controller simply connects the module to the battery when the battery is discharged. When the 75W module in this example is connected directly to a battery charging at 12 volts its power production is artificially limited to about 53 watts. This wastes a whopping 22 watts or nearly 30% of the available power!

Patented MPPT technology used in Solar Boost controllers operates in a very different fashion. The Solar Boost controller continually calculates the module's maximum power voltage, in this case 17 volts. It then operates the module at its maximum power voltage to extract maximum power. The higher power extracted from the module is then provided to the battery in the form of increased charge current. In conditions where extra PV power is not available, Solar Boost controllers will operate as a conventional controller with very low voltage drop.

The actual charge current increase you will see varies primarily with module temperature and battery voltage. In comfortable temperatures, current increase typically varies between 10 to 25%, with 30% or more easily achieved with a discharged battery and cooler temperatures. What you can be sure of is that Solar Boost charge controllers will deliver the highest charge current possible for a given set of operating conditions.

Solar Boost 1524iX is a 12V or 24V multi-stage Maximum Power Point Tracking (MPPT) photovoltaic battery charge controller capable delivering up to 15 amps or 20 amps depending on PV modules and battery voltage. An auxiliary output can serve as either a 2A auxiliary battery charger, or as a load controller with or without variable Dusk-to-Dawn lighting control. The 1524 includes an IPN Network interface which allows multiple charge controllers to communicate with each other and operate as a single charging machine.

Through the use of patented MPPT technology the 1524 can increase charge current up to 30% or more compared to conventional controllers. The 1524's sophisticated three stage charge control system improves battery performance and life while minimizing battery maintenance. The unit is fully protected against voltage transients, over temperature, over current, reverse battery and reverse PV connections.
