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... -
Page 5: Three Stage Charge Control
Installation and Operation Manual THREE STAGE CHARGE CONTROL The 2512 is factory configured for a three stage charging process, Bulk, Acceptance and Float. The three stage charge process provides a somewhat higher charge voltage to charge the battery quickly and safely. Once the battery is fully charged a somewhat lower voltage is applied to maintain the battery in a fully charged state without excessive water loss. -
Page 6: Current Limit
Blue Sky Energy - Solar Boost 2512i and 2512iX CURRENT LIMIT If PV input power is high enough to produce more than 25 amps of output current, the 2512 will automatically prevent output current from exceeding 25 amps. Note that when the 2512 exits current limit, it will briefly show Acceptance on the Charge Status Indicator even though battery voltage may be low. -
Page 7: Electrostatic Handling Precautions
Installation of the optional battery temperature sensor enables temperature compensation of all charge voltage setpoints. In a multi-controller system a single temperature sensor must connect to the IPN master. Do not attach a sensor or connections other than Blue Sky Energy battery temperature sensor p/n... -
Page 8: Battery And Pv Wiring
Blue Sky Energy - Solar Boost 2512i and 2512iX BATTERY AND PV WIRING A desirable installation will produce a total system wiring voltage drop of 3% or less. The lengths shown in Table 2 are one way from the PV modules to the battery with the 2512 located along the path. -
Page 9: Auxiliary Battery Charge
Installation and Operation Manual AUXILIARY BATTERY CHARGE – DIP #3 OFF The auxiliary charge function is used to charge an auxiliary battery of the same voltage as the primary battery. If the primary battery is charging in Acceptance or Float, up to 2 amps is diverted to the auxiliary battery at the same charge voltage. Auxiliary battery charge is disabled during Bulk or Equalization. Use 14 awg wire to minimize voltage drop and 25 amp maximum over current protection. -

Blue Sky Energy - Solar Boost 2512i and 2512iX IPN NETWORK WIRING FIGURE 5 IPN Network Address – DIP’s #1, #2 & Jumper A2 (Omitted on SB2512i) A single controller must be set to IPN network address 0 (zero). In a multi-controller system one controller must be set to address 0 (zero) to serve as the master. -
