Blue Sky Energy - Solar Boost 1524iX
BATTERY TEMPERATURE SENSOR
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
930-0022-20. The cable may be lengthened or shortened if necessary. Be certain to observe proper RED/BLK polarity.
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 1524 located along the path. Wire length can be increased inversely proportional to actual current. If current was reduced by ½, wire lengths could
be doubled and still provide the same 3% voltage drop.
CAUTION: Battery, PV and Auxiliary Output terminal block accept #20−10 AWG wire and are to be tightened to 9 in-lb (1
nm). IPN Network and Temperature Sensor compression terminals accept #24−14 AWG wire and are to be tightened to 2.1 in-
lb (0.24 nm). DO NOT connect Bat– and PV– together outside of the unit or improper operation will result. Bat– and PV– connect
together internally.

AUXILIARY OUTPUT
The auxiliary output can serve one of three functions; a 2 amp auxiliary battery charger, a 20 amp 12V or 15 amp 24V load controller with Low Voltage
Disconnect (LVD), or a 15/20 amp variable Dusk-to-Dawn lighting controller. The Charge/Load function is selected by DIP switch #3 shown in Figure 3. The IPN-
ProRemote is required to adjust LVD thresholds or enable Dusk-to-Dawn lighting control. Auxiliary outputs in a networked multi-controller system will function
normally, but only the auxiliary output in the master can be configured or monitored using the IPN-ProRemote. The auxiliary output Load Indicator will illuminate
whenever the auxiliary output is ON.
CAUTION: The auxiliary output cannot perform both auxiliary battery charge and load control functions at the same time. Do not
connect to the Load+ terminal for auxiliary battery charge.
