Installation
Checking Managed AC Coupled Systems
For systems incorporating Managed AC Coupling, the following items should be verified.
Common System Checks on page 35 and other relevant sections should be completed first.
Refer to relevant installation document for the particular brand of
Selectronic Certified (SCERT) solar inverter and ensure the system has
been installed and commissioned according to that document before
completing the following checklist.
•
Turn on the DC supply to the SP PRO(s).
•
Long press SP PRO ON button so that the blue AC Load LED is lit.
•
If the solar inverter comes on with AC volts (Fronius SCERT), turn on
its AC. Leave off the PV volts.
• If the solar inverter comes on with PV volts (ABB SCERT), turn on
the PV volts to the solar inverter. Leave off the AC volts.
•
Connect SP LINK to the SP PRO System Manager (L1 Manager).
