Blue Sky Energy - Solar Boost 2512i-HV and 2512iX-HV

PRODUCT DESCRIPTION
Solar Boost™ 2512i-HV and 2512iX-HV are improved versions of the original SB2512i and SB2512iX 12 volt 25 amp Maximum Power Point Tracking
(MPPT) photovoltaic (PV) battery charge controllers. The new HV versions retain their original 25 amp 340 watt rating when used with conventional 12 volt
36 cell PV modules, but are also able to operate up to 270 watts of higher voltage 60 cell “grid tie” type modules. The full featured SB2512iX-HV includes all
the features described in this manual. The SB2512i-HV omits certain features to reduce cost.
The 2512’s patented MPPT technology can increase charge current up to 30% or more compared to conventional controllers. MPPT also allows the
use of higher voltage 60 cell modules by converting higher PV voltage down to charge a 12 volt battery. The 2512’s sophisticated 3-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 and reverse polarity. The IPN Network display connector provided in both versions allow use of optional remote displays or a UCM.
Additional features included in the SB2512iX-HV version of the product include a battery temperature sensor input, equalization capability, full IPN
Network interface, and an auxiliary output. The versatile auxiliary output can operate as either a 2 amp battery charger for a second battery, or serve as a 25
amp load controller or 25 amp variable Dusk-to-Dawn lighting controller. The full IPN Network interface included in the SB2512iX-HV allows multiple charge
controllers to communicate with each other and coordinate their activity to charge the battery as a single coordinated charging machine.
FEATURES OMITTED IN THE SOLAR BOOST 2512i-HV

OPERATION
Charge control and MPPT operations are fully automatic. At night when PV power production stops, the PV array is disconnected from the battery to
prevent unwanted current drain. There is a 5 second turn-on delay, and a 45 second turn-off delay.
¾ WARNING: The 2512 operates on battery power, not PV power. A battery must be connected with a minimum voltage of 9V
for the unit to operate. Battery voltage on the battery terminals of the 2512 must be the same as actual battery voltage within a
few 10ths of a volt for proper operation. DO NOT disconnect the battery with PV power applied as appliances still attached to
the output of the 2512 may be damaged by voltage spikes resulting from sudden removal of the battery, particularly when used
with higher voltage 60 cell PV modules. ALWAYS remove PV power first before disconnecting the battery.
CHARGE STATUS INDICATOR
A charge status indicator is provided on the face of the 2512, and on the optional remote displays. If net battery charge current is greater than ≈3 to 5 amps
per 100 amp-hours of battery capacity the charge status indicator can provide a rough indication of battery state of charge.

TABLE 1
AUXILIARY OUTPUT INDICATOR (Omitted on SB2512i-HV)
An Auxiliary Output indicator labeled “LOAD” is provided on the face of the SB2512iX-HV, and is omitted on the SB2512i-HV. The indicator will be ON when
the auxiliary output is ON providing power to a load, or charging an auxiliary battery. Default operation of the auxiliary output is Auxiliary Battery Charge and the
indicator may turn ON even though an auxiliary battery may not be connected. Auxiliary Output status can also be viewed on the IPN-ProRemote.
OPTIONAL REMOTE DISPLAYS OR INTERNET COMMUNICATION
There are two available remote displays, the low cost IPN-Remote and the full featured IPN-ProRemote. The IPN-Remote is a basic 3-digit LED type
voltage, current and charge mode display without setup or control capability. The full featured IPN-ProRemote provides setup capability and enhanced
monitoring of charge controllers on the IPN network. It also provides a complete battery system monitor with various amp-hour counters and a highly accurate
“fuel gage” type battery level indicator. A Universal Communication Module (UCM) may also be used for communication with other devices or to access the
charge control system remotely over the Internet.
