Operation Manual Addendum

430-0022 A

Manual Addendum Purpose

This addendum applies to Solar Boost 3024Di charge controllers (p/n SB3024Di) and describes installation and use of the digital
display. It is meant to be used in conjunction with Solar Boost 3024i operators manual (p/n 430-0018) revisions A, B and C. The
information in this manual addendum is included in Solar Boost 3024i operators manuals revisions D and later.

Operation

The digital display can monitor either a single charge
controller, or the combined total of up to 8 charge
controllers on a single IPN network. A low power LED
display is used to provide both very low power
consumption (≈0.15W) and excellent readability.

Battery voltage is continuously displayed when the
charge controller it not charging the battery. Once the
charge controller turns on and begins charging the battery
the display will alternate between battery voltage and
charger output current, each shown for 3 seconds. The
display can show readings of up to 99.9 volts or amps
maximum. Readings greater than 99.9 will display as

99.9.

The Charge Status LED will be off when the charge
controller is not charging, and will be on solid or blinking
when the charge controller is charging the battery. The
Charge Status LED operates in the same manner as the
Charge Status LED in the charge controller except that it
will turn on whenever any charge controller on the IPN
network is charging the battery. If the charge controller is
delivering at least 3 to 5 amps per 100 amp-hours of
battery capacity, the charge status LED can provide a
rough indication of battery state of charge as shown on the
front panel graphics. Refer to the charge controller
operators manual for a complete description of Charge
Status LED operation.

¾ Whenever the AMPS Indicator in the display is ON, output current is being displayed. Which output



current to display is configured during setup and can be set to show either total output current of all
chargers on the IPN network (factory default setting), or the output current of a particular charger unit

on the IPN network. Battery voltage is displayed whenever the AMPS Indicator is OFF.

Setup and Installation

A four position DIP switch on the display circuit board configures
the output current display. The factory default setting of total output
current from all charge controllers on the IPN network is suitable for
both a single charge controller, or multiple charge controllers if only
one controller has a display. If more than one charge controller is
present on the IPN network and it is desired to have the display
show only the output current from it’s charge controller, the IPN
network address of the display must match the IPN address of the
charge controller it is intended to monitor.

TOTAL OUTPUT CURRENT OF ALL

CHARGERS ON IPN NETWORK

Network connection and power for the display are provided by the Solar Boost 3024i using the short telephone cable supplied. The
cable should connect between the IPN Display connector on the Solar Boost 3024i main circuit board and the IPN Network connector
on the display circuit board.

¾ Note that standard 4-pin telephone cables swap pin numbers end-to-end. This end-to-end pin swap is



required for the display to operate properly. If cables are custom terminated or cable couplers are used,
be certain the pin swap is maintained as shown below.

Troubleshooting Guide

SYMPTOM PROBABLE CAUSE ITEMS TO EXAMINE OR CORRECT

Completely dead, no
display

Display turns on, but
battery voltage displays
“– – –“ rather than a
number

When charger turns on,
output current displays
“– – –“ rather than a
number
When charger turns on,
output current displays
but the value seems
incorrect

Voltage or current value
seems to be stuck and
does not change

No power Charge controller not properly powered

Cable faulty, not plugged in or cable pins do not swap
Display not communicating with
charge controller

Output current display selection
set for an address not present on
the IPN network

Output current display selection
set for wrong IPN network
address

Bat– connected to PV– outside
charge controller
Display or charge controller IPN
network addressed changed

Display lost communication link
with charge controller

Cable faulty

One charge controller is not set to be Master, or more than

one charge controller is set to be Master

One or more charge controllers on network has open Bat –

connection preventing communication

Configure display IPN network address DIP switch to properly

read output current of a charger present on the IPN network

Configure display IPN network address DIP switch to properly

read output current of a charger present on the IPN network

Some charge controllers require Bat– not be connected to PV–

outside charge controller, see charge controller manual.

Configure display IPN network address DIP switch to properly

read output current of a charger present on the IPN network

Intermittent faulty display cable
