SP PRO Series 2i Managed Batteries Installation
Introduction
This instruction will show how to setup and install a managed Lithium battery with a Selectronic SP PRO
Series 2i in either a single phase system or Advanced Multiphase system (Three phase or Split phase).
NOTES:
When installing an Advanced Multiphase system, also refer to installation guide:
IN0052_xx Installation of an Advanced Multiphase system.
In an Advance Multiphase system the CAN bus cable is ONLY connected from the battery bank to
the L1 SP PRO. There is no connection to the CAN on either the L2 or L3 SP PRO.
Refer to the table below to understand which installation kit is the right choice for your application.
Note that the table below is equally applicable to both on-grid and off-grid systems.

Preparation
If installing Sonnenschein@home Lithium 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 and SPMC480 installed in
each battery box. Battery fuses are not supplied with battery.
If installing LG Chem Stand-Alone modules (LG Chem Rack Mount) you must also purchase the
option Lead CAN RJ45-DB9 LM CS1022 stock code 005289.
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:
Install batteries according to the manufacturer installation manual.
Install the latest version of SP LINK on your computer from http://www.selectronic.com.au
If the system is Advanced Multiphase with BYD batteries, wire in the Pre-charge.
Connect Communication cable from battery to the SP PRO.
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.

Section 3 for LG RESU (Single battery)
1. Do not connect any wires to the pre-charge / battery sense terminals. The battery sense voltage
is read from the RESU battery BMS.
2. Leave the battery temperature sensor connected and rolled up inside the SP PRO. This is not
used in a managed battery system.
3. Follow the RESU instructions to install the RESU battery.
4. Configure the LG Chem : 1&2 = OFF and 3&4 = ON.

SP PRO Series 2i Managed Batteries
Installation Note
Turn on the Battery DC to the SP PRO
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 Lithium 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 and US3000 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 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
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.

SP PRO Configuration
1. Start Selectronic SP LINK.
2.
3. Follow the wizard to create a configuration for the SP PRO.
4. When the wizard is complete, select File > Site Information > Save to save the created site.

Installation Note
5. SP LINK will automatically detect when the SP PRO is ON and the USB cable is connected.
6.
The default settings passcode is 74.
7. NOTE: If you have changed the AC coupled string inverter to one not supported by the firmware
currently in the SP PRO, you may be prompted to replace the firmware after you have uploaded
the configuration.
If so, follow the prompts to upload firmware and restart on completion.

SP PRO Series 2i Managed Batteries
Installation Note
Testing the Batteries
1. Turn OFF the main DC breaker, waiting 20 seconds and turn back ON.
2. After the SP PRO has powered up and the front panel LEDs are stable, check the green LEDs on
the comm card.
Note: 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,
The third stage is what is referred to as stable.
The right LED should be steadily ON.
The left LED should flash approximately once per second.
NOTE: There may be a delay of up to 60 seconds after power on before the left LED
starts flashing.
3. Navigate , the values on
this screen will be valid for the batteries.
4. The values displayed under Battery Management are those read from the batteries.
The SP PRO uses these values to adjust the charge current and to limit the discharge current in
the battery.
Note: The SP PRO will be beeping and
the batteries will turn off after 5-10
minutes if there is a problem with the
communications between the SP PRO and
the batteries.
Note: If Module Status readings are greyed out they are not applicable for your battery type.

SP PRO Series 2i Managed Batteries
Installation Note
Operation of the SP PRO
The SP PRO reads all the data out of the batteries and automatically adjusts the battery current to suit.
This means the operation is a little different than with other battery banks.
When connected to the grid, the operation of the SP PRO is as follows:
1. When the SP PRO is charging the charge c
displayed in Battery Management (see diagram above
2. When the SP PRO is supporting the load, the current taken from the battery bank will not exceed
discharge current is not exceeded.
When the grid fails, the operation of the SP PRO in standalone mode is:
1. When the SP PRO is charging from the PV, the ch
2. When the SP PRO is supporting the load, but the current drawn from the battery exceeds the
the load so high that the AC voltage drops below 200V for 10 seconds, the SP PRO will shut
down as the battery can no longer support the load. The customer then needs to reduce the load
so that when the SP PRO retries, it can continue to provide backup power.
