SP PRO Fronius Primo Managed AC

Coupling

Introduction

The SP PRO and Selectronic Certified (SCERT) Fronius 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. 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 Primo SCERT 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 SCERT.

This document only applies to Fronius Primo 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 Primo SCERTs 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 Primo configuration as indicated in this

document.

•The SP PRO and Fronius Primo SCERT Managed AC coupling cannot be used

with a Fronius Smart Meter. See Appendix III: Disable Fronius Smart Meter

(page 40).

•Installer must contact Fronius for the Profile Settings access code.

•SP PRO Series 2i and Series II: Single and Advanced Multiphase compatible.

•SP PRO Series I: Single Phase only.

For Fronius Primo SCERT that need to be re-programmed, see Appendix II: Fronius Step

Through Configuration (page 28).

Installation Notes

Fronius SCERT “Backup Ready”Connection

When Selectronic Certified Fronius Primos are installed without an SP PRO,

1. A link must be fitted to the orange “Fronius Datamanager Connector” from the “+” pin

to IO “2” pin so that Fronius Primos can produce full power.

2. The country code must be set to AU –Australia

Please note: The link is only required when the Primo inverter is installed without an SP PRO.

Installation Notes

Overview –Series 2i

The diagram below shows a managed AC coupled system with five Fronius Primos.

System Requirements

To successfully install the inverters, there are particular system requirements that need to be

met.

•SP LINK Site Configuration Wizard must be used to verify:

1. Combined maximum Fronius AC output

2. Battery bank size

•The combined maximum AC output of all the connected Fronius Primos must be verified

in the SP LINK Wizard.

•Battery bank must be sized to suit the SP PRO model and the combined maximum AC

Output power of the Fronius Primos, check the SP LINK Wizard.

•The SP PRO must have firmware version 9.09 or higher.

•The Fronius Primo must be Selectronic Certified.

•Maximum of five Fronius Primos per SP PRO.

To configure the SP PRO - Fronius system, the Site Configuration Wizard in SP LINK’s Easy Start

Guide must be used.

System Requirements

To successfully install a SP PRO Series I - Fronius managed system, there are particular system

requirements that need to be met.

•SP LINK Site Configuration Wizard must be used to verify:

1. Combined maximum Fronius AC output

2. Battery bank size

•To install an AC coupled system using a Series I SP PRO an additional AC coupling

adaptor (stock code 005077) is required.

•The SP PRO must have firmware version 9.09 or higher.

•The Fronius Primo must be Selectronic Certified.

•Maximum of five Fronius Primos per SP PRO

Installation Notes

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:

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.

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.

SP PRO Fronius Primo Managed AC Coupling

Installation Notes

Installation

The SP PRO and Fronius Primos 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 Primo from 1 up to 5 so that each inverter can be

easily referenced within SP LINK.

In a multiphase system, label each Fronius Primo connected to L1, from L1-1 to L1-5. Do the

same for each of the Fronius Primos connected to L2, from L2-1 to L2-5, and so on.

This number 1 to 5 is used for the communications link addressing. See Configuration section.

Fronius AC wiring

For correct and safe operation, the Fronius AC output wiring must be connected to the AC Load

terminals of the SP PRO in accordance with local wiring rules.

Communications Link (RS485)

For Series II, see Appendix IV.

The communication link always starts at the SP PRO, then connects to the first Fronius Primo

(Master). The Fronius link is used to connect subsequent Fronius Primos on the same phase as

the SP PRO. Do not connect Fronius Primos on different phases together.
