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.
