Blue Sky Energy-Solar Boost 1524iX MPPT Solar Charge Controller, 20A@12V or 15A@24V

Solar Boost 1524iX’s advanced fully automatic 3-stage charge control system will properly charge flooded lead-acid, AGM and Gel batteries 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 IPN™ 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.


  • Patented MPPT Technology Increases Charge Current up to 30% or more
  • Optional IPN-ProRemote Display provides charge control & full featured battery system monitoring
  • Clear anodized faceplate, galvanized mounting box and conformal coated electronics resist corrosion
  • 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

Blue Sky Energy’s advanced Integrated Power Net™, 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.

The perfect controller for a variety of applications, including marine, RV, Off-Grid, PV street lighting and PV traffic signals.
