Blue Sky Solar Boost 3024iL, MPPT Charge Controller, 30 Amp 24 Volt, no display (SB3048iL)

Product Description:

Maximum Power Point Tracking technology allows the Solar Boost 3024iL to increase charge current up to 30% or more compared to conventional charge controllers. 30% is max under ideal conditions, typical boost is 10% to 20% with an MPPT controller

The 3024iL'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 maintenance. The dual 30/40 amp rating will deliver at up to 30 amps in 24 volt systems, or up to 40 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 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 battery in an RV or boat. The auxiliary output can also provide fully adjustable dusk to dawn lighting control.

Blue Sky Energy's Integrated PowerNet™, 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 communication hardware to operate.

Note: For optimal Maximum Power Point Tracking performance, it is recommended that MPPT charge controllers be used in conjunction with uniform solar arrays consisting of multiple, identical solar panels. MPPT charge controllers will still work with mixed arrays, but at reduced efficiencies, which defeats the whole point of MPPT technology. These devices were designed to calculate the most efficient charging characteristics given the assumption of a uniform array. Mixed arrays, by definition throw this calculation off.

How Do Solar Boost Charge Controllers Increase Charge Current?

Solar Boost charge controllers increase charge current by harvesting more PV power. A conventional charge controller simply connects the PV module to the battery when the battery is discharged which can artificially limit how much power a PV module can deliver. Patented Solar Boost MPPT technology operates the PV module at it’s optimum voltage where it can produce the greatest amount of power rather than at battery voltage. The higher power extracted from the module is then provided to the battery as increased charge current. 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.
