Solar Boost™ 2512i-HV & 2512iX-HV

Solar Boost™ 2512i-HV  &  2512iX-HV
Solar Boost™
2512i-HV & 2512iX-HV
20/25 Amp / 12 Volt MPPT Charge Controller
Available both as low cost and full featured
versions. Great for cost sensitive applications that
require a quality, reliable MPPT controller capable
of running 60 Cell modules. Full featured version
includes LVD load control or lighting control.
Patented Maximum Power Point Tracking technology allows
Solar Boost 2512i-HV and 2512iX-HV to increase charge current
up to 30% or more compared to conventional charge controllers.
The new higher input voltage capability of the HV version
product now allows the use of higher voltage lower cost 60 cell PV
modules to charge a 12 volt battery. Don’t waste your money by
throwing PV power away! Get the power you paid for with a Solar
Boost charge controller.
The lower cost Solar Boost 2512i-HV provides an advanced fully
automatic 3-stage charge control system to ensure the battery is
properly and fully charged, resulting in enhanced battery
performance with less maintenance. A partial IPN™ network
interface is also included to allow use of the Universal
Communication Module (UCM), and IPN-Remote and
IPN-ProRemote displays.
Additional features provided in the Solar Boost 2512iX-HV
version include automatic equalization, battery temperature
sensor input, full IPN network compatibility, and an auxiliary
output. The auxiliary output can serve as a 25 amp load controller,
25 amp lighting controller 1, or as a 2 amp auxiliary battery
charger. The auxiliary battery charge feature is ideal for charging a
separate battery such as the engine battery in an RV.
Blue Sky Energy’s advanced Integrated Power Net™, or IPN
Network, allows multiple charge controllers to communicate with
each other and coordinate their activities to charge the battery as a
single coordinate charging machine. The IPN network also allows
networked controllers to share an optional battery temperature
sensor, UCM and remote display. Complete IPN network
functionality is provided within the charge controller and no
additional hardware or software is required.

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.
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.
Typical 75W PV Module Performance @ STC
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
