Installing a Selectronic Certified Fronius
Primo in a Managed AC Coupled system
INTRODUCTION
The SP PRO FRONIUS Selectronic Certified (SCERT) Primo Managed AC Coupling provides a
method of linking the single phase Fronius Primo range of grid tie inverters to the SP PRO via
the AC Load supply so that regardless of whether the grid or a generator is connected, the
SP PRO can manage and control the Fronius grid tie inverters.
Each SP PRO can manage a maximum of five Fronius grid tie inverters by commanding each
one to output the required amount of power to simultaneously supply the load, export to the
grid and charge the battery bank as required at any particular point in time. This is done via a
communications link between the SP PRO and the Fronius Primo.
This document only applies to Fronius SCERT inverters that have been pre-programmed by
Selectronic and details the additional steps needed to install the managed system.
The SP PRO and Fronius inverters must be installed as per their individual installation
instructions with the additional allowance of communications cables linking all of the inverters
together.
Note: This document needs to be read in conjunction with the SP PRO Instruction Manual and
the Fronius Primo Instruction Manual.
Only make adjustments to the Fronius configuration as indicated in this document.
The SP PRO SCERT Primo Managed AC coupling CANNOT be used with Fronius Smart
Meter. Refer to Appendix III: Fronius Smart Meter Configuration (page 50).
Must contact Fronius for the Profile Settings access code.
Series 2 SPPRO : Single and Multi Phase compatible.
Series 1 SPPRO : Single Phase Only!
For Fronius SCERT that need to be re-programmed see
Appendix II: Fronius Step Through Configuration (page 37)

FRONIUS SCERT “BACKUP READY”CONNECTION
When Selectronic certified Fronius inverters are installed without an SP PRO, a link must be
fitted to the orange “Fronius Datamanager Connector” from the “+” pin to IO “2” pin so that
Fronius inverters can produce full power.
PLEASE NOTE:
a. The link is ONLY required when the Fronius inverter is installed without an SP PRO
inverter.

MINIMUM BATTERY CAPACITY FOR SOLAR HYBRID &OFF GRID SYSTEMS
Each application will have a minimum battery capacity and a maximum allowable PV, please
refer to the battery manufacturers data sheet as well as the guidance given in the SP LINK Site
Configuration Wizard.
Note:
a. For a Solar Hybrid (grid connected) system, the minimum battery capacity that must be
connected to the SP PRO varies depending on SP PRO model.
When the system is islanded (e.g. during a grid outage) the SP PRO will limit the output
of the AC coupled solar based on the actual installed battery size.
b. For an Off Grid system, the minimum battery capacity that must be connected to the SP
PRO varies depending on SP PRO model, an overriding minimum battery capacity and
the combined maximum Fronius Primo AC Output.

INSTALLATION
The SP PRO and Fronius inverters must be installed as per their respective installation
instructions. Particular instructions directly related to Managed AC Coupling are listed below.
It is good practice to number each Fronius inverter from 1 up to 5 so that each inverter can be
easily referenced within SP LINK.
Series 2 Only - In a Multi (three or split) phase AC coupled system label each Fronius inverter
L1-1 to L1-5 for the Fronius inverters connected to SP PRO L1, L2-1 to L2-5 for those connected
to L2 and so on.
This number 1 to 5 is used for the Communications Link addressing. See Configuration section.
FRONIUS AC WIRING
The Fronius AC output wiring must be connected to the AC Load terminals of the SP PRO in
accordance with local wiring rules for correct operation.

COMMUNICATIONS LINK (RS485)
The communication link always starts at the SP PRO and links to the “AC Coupled Interface
PCA”, then connects to the first Fronius Inverter (Master). The Fronius link is used to connect
subsequent Fronius inverters ON the same phase as the SP PRO. Do Not Connect Fronius
inverters on different phases together.
To install the AC Coupled Interface PCA, remove the bottom two screws from the Expansion
Card and replace them with the provided 2x stand offs. Then mount the AC Coupled Interface
PCA to the Expansion Card inside the SP PRO close to the Serial Communication PCA and
connect the connector with the two blue wires to J2 on the Expansion Card as illustrated.
Connect the RJ45 Connector lead from the AC Coupled Interface PCA “To RS485 Port
2” to the SP PRO Serial Communication PCA RS485 Port 2.
Connect the second RJ45 lead from the AC Coupled Interface PCA “To Other AC
Coupled Inverters” to Fronius Inverter 01 (Master), Fronius Datamanger connector
(see section “Fronius RS485 Connection to Inverter 01 (Master)” page 11).
Connect the AC Coupled Interface PCA power loom (12V) from AC Coupled Interface PCA
“12V DC Power J4” to the SP PRO Serial Communication PCA 12V connector.
Note: Do not connect any RJ45 leads to the AC Coupled Interface PCA “To ABB AC Coupled
Inverter” connector as the pin out is different to the Fronius Inverter connection.

Using the supplied ‘CAT5’ network cable connect one end to the AC Coupled Interface PCA “To
Other AC Coupled Inverters” on the SP PRO. At Fronius Inverter 01 (Master), cut off the
non-connected RJ45 connector, expose and crimp the wires using wire crimps or
alternatively use a longer cable as required (not supplied) as outlined in the table below.
The Fronius link is used to connect subsequent Fronius inverters ON the same phase
as the SP PRO. Do Not Connect Fronius inverters on different phases together.
PLEASE NOTE: There are two different colour coding for RJ45 plugs, T568A and T568B, it is
common that either colour code is used. To ensure correct connections please check that the
“RS485 RJ45 Adaptor pin #” (see below table) corresponds to the “Fronius RS485 Connector”
connection by buzzing out the lead before connecting it to the Fronius or the SP PRO inverter.

CONFIGURATION –ADDITIONAL SETTINGS
It is recommended that the Site Configuration wizard (in SP LINK 9.4 or higher) be
used to configure the SP PRO settings. Using the wizard will ensure all SP PRO
settings are compatible with the managed AC coupled system.
The settings detailed below will be set when the Site Configuration Wizard is used to configure
the SP PRO. Only the settings required to enable Fronius Managed AC Coupling are shown. The
remainder of systems settings will be set by the Site Configuration Wizard.
The SP PRO must be configured before any of the Fronius inverters are energised.
The Fronius inverters are configured to Solar Net as default and the Inverter Number must be
set sequentially from 01. (See “Programming the Fronius” section).
Make sure in the SP LINK tab CONFIGURATION SETTINGS > SYSTEM the follow settings are
set.
Set String Inverter to Fronius.
Number of Devices is set to the number of Fronius inverters installed in the system.

FRONIUS CONFIGURATION
The settings listed below are required to be configured in each Fronius inverter in order for the
system to operate correctly.
1. Isolate the DC solar from the Fronius inverter(s) (via the appropriate DC circuit breaker).
Note: DO NOT connect the PV solar until system is configured.
2. Ensuring that the SP PRO AC Load supply is present at the Fronius Inverter, switch ON
the AC supply to the Fronius inverter.
3. When the Fronius inverter is powered for the first time, select the “language” for the
inverter and press the ENTER (↵) key.
Then “Select Country”,
-For Grid connect, scroll to AU-Australia (↓) and press the ENTER (↵) key.
-For Off Grid,scroll to MG50-Microgrid 50Hz (↓) and press ENTER (↵).
