P–The pre-charge/Battery sense wiring must be installed when using a BYD battery in an Advance
Multi-phase (AMP) system. See Installation note IN0052_xx 005303 Installation of an Advanced
Multiphase system.
S–The battery fuse or circuit breaker must be turned ON before the battery bank is started (button
press on the master battery) when using the LG Chem Stand-Alone modules.
These install kits are required where a battery requires management between the SP PRO and
battery via CAN bus communications. If your chosen battery requires CAN bus connection and is
NOT on the list above, it cannot be used.

Preparation
If installing Sonnenschein@home batteries: Make sure there are 2x 200A NH fuses (ABB
OFAF1H200 or equivalent) for SPMC482 OR 2 x 160A NH fuses (ABB OFAF1H160 or equivalent)
for SPMC481 installed in each battery box. Battery fuses are not supplied.
NOTE: The battery fuse size for the SPMC482 when used with a Sonnenschein@home Lithium must be
200A. In this application ONLY, do not use 250A fuses as specified in the SP PRO installation manual as
this may damage the Sonnenschein@home lithium. A 200A fuse is suitable in this application as the
battery voltage for the Sonnenschein@home lithium is higher (54 VDC) than nominal (48 VDC).
Summary of steps
The following is a summary of the steps needed to complete the installation.
Once the installation is completed, use the below points as a check list:
Make sure the appropriate Battery kit is on site.
Install batteries according to the manufacturer’s installation manual.
Install the latest version of SP LINK (11.15 or higher) on your computer from
http://www.selectronic.com.au
If the system is Advanced Multiphase with BYD batteries, wire in the Pre-charge.
Connect to the SP PRO via the original green comm card using SP LINK software.
Update the SP PRO firmware, selecting a firmware suitable for your AC coupled inverter if
applicable.
Install the blue or black comm card in the SP PRO.
Connect Communication cable from battery to the blue or black comm card in the SP PRO.
Update firmware in blue or black comm card to 2.06 or higher using SP LINK.
Create the configuration for SP PRO using the Site Configuration Wizard in SP LINK.
Connect to the SP PRO via SP LINK and save the configuration to the SP PRO.
Turn battery power OFF and back ON again to the SP PRO.
Test and commission the system.

SP PRO Interactive Inverter Charger
Installation Note
SP PRO Firmware Update
The SP PRO firmware must be 11.11 or higher. You must install SP LINK 11.15 or higher on a Windows
computer, connect to the SP PRO and update its firmware. This is done by following the steps below:
1. Leave the original green comm card in the SP PRO until the firmware update process is
complete.
2. Download the SPLINK software from the Selectronic Web site and install it on a Windows PC.
Windows XP, Vista, 7, 8.1 and 10 are supported.
http://www.selectronic.com.au/splink
3. Connect the PC to the SP PRO via the supplied USB cable.
4. Connect the DC power to the SP PRO. This is done as follows:
For BYD B-Plus 2.5 modules, BYD B-Plus 13.8 BYD B-Plus 15.5, turn ON the battery bank
by pressing the ON button. Turn on the Pre-charge / Battery Sense (If the system is
Advanced Multiphase) and wait until the SP PRO comes on, then turn on the Battery
Breaker or switch.
For LG Chem RESU –Turn ON the system DC breaker of fuses to the SP PRO then turn
ON the battery bank circuit breaker(s).
For Pylontech US2000 –Turn ON the battery by switching the On/Off switch to the ON
position.
For Sonnenschein@home –Leave the system DC circuit breaker or fuses OFF and turn
the battery ON by pressing the ON button (adjacent to the fuse holder). When the relay
inside the battery clicks indicating the batteries have come ON, turn ON the system DC
breaker or fuses.
For LG Chem Standalone (Rack Mount) –Turn ON the system DC breaker or fuses to the
SP PRO then turn ON the battery bank by pressing the ON button.
Wait until the SP PRO front panel LEDs are stable.
NOTE:
a. During the SP PRO power up, the front panel display cycles through three stages. First, all
LEDs turn green from bottom up, second, all LEDs turn red from bottom up and third, some
LED’s will be flashing while the battery LEDs are ON solid green. The third stage is what is
referred to as stable.
b. Perform the following tasks promptly, as the batteries might shutdown in 5-10 minutes
without the CANBUS communications. If this happens, turn the batteries ON and restart the
process.
5. Start Selectronic SP LINK.

Check Communications Card Firmware
The Communication Card firmware must be 2.06 or higher.
A Communication Card with firmware 0.05 or higher can be updated using SP LINK.
To check and update the firmware if required, follow the steps below:
Note: Each battery type has a different power ON procedure. If the correct procedure for a given
battery type is not followed, the battery may not turn ON and run.
1. Connect the DC power to the SP PRO. This is done as follows:
For Sonnenschein@home –Leave the system DC circuit breaker or fuses OFF and turn
the battery ON by pressing the ON button (adjacent to the fuse holder). When the relay
inside the battery clicks, indicating the batteries have come ON, turn ON the system DC
breaker or fuses.
For LG Chem RESU –Turn ON the system DC breaker or fuses to the SP PRO then turn
ON the battery bank circuit breaker(s).
For Pylontech US2000 –Turn ON the battery by switching the On/Off switch to the ON
position.
For BYD B-Plus 2.5 modules, BYD B-Plus 13.8 BYD B-Plus 15.5, turn ON the battery bank
by pressing the ON button. Turn on the Pre-charge / Battery Sense (If the system is AMP)
and wait until the SP PRO comes on, then turn on the Battery Breaker or switch.
For LG Chem Rack Mount –Turn ON the system DC breaker or fuses to the SP PRO then
turn ON the battery bank by pressing the ON button.
Wait until the front panel LEDs are stable.
NOTE:
a. During the SP PRO power up, the front panel display cycles through three stages. First, all LEDs turn
green from bottom up, second, all LEDs turn red from bottom up and third, some LED’s will be flashing
while the battery LEDs are ON solid green. The third stage is what is referred to as stable.
b. Perform the following tasks quickly as the batteries might shutdown in 5-10 minutes without the
CANBUS communications. If this happens, turn the batteries ON and restart the process.
2. After the SP PRO has powered up and the front panel LEDs are stable, check the green LEDs on
the blue or black comm card.
The right LED should be steadily ON.
The left LED should be ON or flash approximately once per second.
3. Start Selectronic SP LINK.
