PRODUCT DESCRIPTION
Solar Boost™ 3024iL is multi-stage Maximum Power Point Tracking (MPPT) photovoltaic battery charge controller capable delivering up to 30A or 40A
depending on PV modules and battery voltage. The auxiliary output can serve as either a 2A auxiliary battery charger, or as a 20A load controller with or
without variable Dusk-to-Dawn lighting control. The 3024 includes an IPN Network interface which allows multiple charge controllers to communicate with
each other and operate as a single charging machine.
PART NUMBERS AND OPTIONS
• SB3024iL.............Solar Boost 3024iL charge controller • SB3024DiL..........Solar Boost 3024iL controller with volt/amp display
• IPNPRO ..............IPN-ProRemote display & battery monitor • IPNPRO-S...........IPN-ProRemote with required 500A/50mV current shunt
• CS-500 ................500A/50mV current shunt • IPNREM..............IPN-Remote display
• 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.
¾ The 3024 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 3024, and on the optional remote displays. If net battery charge current is greater than ≈3 to 5A per
100 amp-hours of battery capacity the charge status indicator can provide a rough indication of battery state of charge.

OPTIONAL DIGITAL DISPLAY
The SB3024DiL includes a digital display of battery voltage and output charge current. The display alternates between voltage and current when
charging. Current is displayed when the “AMPS” indicator is on and can be the total of all controllers on the IPN network (factory default), or the current of a
single controller on the IPN network. An automatic night time dimming feature reduces display brightness when PV charge is OFF.
OPTIONAL REMOTE DISPLAYS
Two remote displays are available. The IPN-Remote has the same display functionality as the SB3024DiL. 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.
MULTI-STAGE CHARGE CONTROL
Bulk Charge
The 3024 will be in Bulk charge when battery voltage is below the Acceptance Charge Voltage setpoint. During Bulk the 3024 delivers as much charge
current as possible to rapidly recharge the battery. Automatic current limit prevents output current from exceeding the 3024’s maximum current rating.
Acceptance Charge
When the battery recovers sufficient charge for voltage to rise to the Acceptance Charge Voltage setpoint (factory set to 14.4/28.8V) current is reduced as
necessary to control at the Acceptance Voltage. The 3024 remains in Acceptance until the battery is fully charged as determined by either;
1. The 3024 has remained in Acceptance for the Charge Time period (factory set to 2 hours).
– OR –
2. With the IPN-ProRemote display, net battery charge current while in Acceptance decreases to the Float Transition Current setting (factory
set to 1.5A per 100 amp-hours of battery capacity).
