Blue Sky Energy - Solar Boost 2512i and 2512iX
PRODUCT DESCRIPTION
Solar Boost™™ 2512i and 2512iX are 25 amp 12 volt Maximum Power Point Tracking (MPPT) photovoltaic (PV) battery charge controllers. The full
featured Solar Boost 2512iX includes all the features described in this manual. The Solar Boost 2512i omits certain features to reduce cost.
Through the use of patented MPPT technology the 2512 can increase charge current up to 30% or more compared to conventional controllers. The
2512’' 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. An automatic current limit feature allows
use of the full 25 amp capability without worrying about overload or nuisance fuse blow from excessive current. An environmentally sealed high current high
reliability relay is used to disconnect the PV array at night to prevent unwanted current drain. An IPN Network display interface is provided in both versions of the
product allow use of the available IPN-Remote or IPN-ProRemote displays.
Additional features included in the Solar Boost 2512iX 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 provide either a 2 amp battery charger for a second battery, 25 amp voltage or
amp-hour based load control, or 25 amp variable Dusk-to-Dawn lighting control. The full IPN Network interface included in the Solar Boost 2512iX allows
multiple IPN compatible charge controllers to communicate with each other and operate as a single charging machine rather than separate charge
controllers.
FEATURES OMITTED IN THE SOLAR BOOST 2512i
The following features described in this manual are omitted in the lower cost Solar Boost 2512i version of the product. See Figure 3 for omitted connectors
and setup selectors.
Battery Temperature sensor input
Full IPN Network interface (for multi-controller coordination)
PART NUMBERS AND OPTIONS
SB2512i ..............Basic Solar Boost 2512i charge controller
IPNPRO .............IPN-ProRemote display & battery monitor
CS-500 ...............500A/50mV current shunt
930-0022-20 .......Battery temperature sensor
OPERATION
Charge control and MPPT operation 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.
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.
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.

AUXILIARY OUTPUT INDICATOR (Omitted on SB2512i)
An Auxiliary Output indicator labeled “"LOAD”" is provided on the face of the SB2512iX, and is omitted on the SB2512i. The indicator will be ON when the
auxiliary output is ON providing power to a load, or charging an auxiliary battery. Auxiliary Output status can also be viewed on the IPN-ProRemote.
OPTIONAL REMOTE DISPLAYS
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.
