Generic AC Coupled Preparation
For more full installation notes see:
IN0034 – SP PRO Generic AC Coupling Installation Notes
To successfully install an SP PRO generic system, particular system requirements need to be met:
•
Combined maximum AC output of all the connected generic inverters must not exceed the continuous
SP PRO output power rating.
•
Battery bank must be sized to suit the SP PRO model and the combined maximum AC output power of the
generic inverters.
•
SP PRO generic AC Coupling is only suitable for grid-connected systems.
•
SP PRO generic AC Coupling cannot control any grid export limits.
•
The Grid Disconnect function in the Solar Hybrid Control must not be used.
•
Using generic AC Coupling, ‘Solar Power’ will not display in Select.live monitoring, battery state of charge
will be correct.
•
Using generic AC Coupling, AC Load data within Select.live monitoring will not be accurate during the
sunshine hours. This will have no effect on battery state of charge.
The SP PRO will not export active power to the grid, as per the requirements of
AS/NZS 4777.2:2200 appendix M.
When designing a generic AC Coupled system, use the
determine the ideal match between battery type and size and the output of the solar inverters.
Powerchain – Split-phase Preparation
A split-phase system is suitable for connection to the 480V split-phase grid supply that is commonly found on
Single Wire Earth Return (SWER) line feeds.
Installing a split-phase system is possible using up to eight SP PRO inverters.
For detailed information on preparing for a split-phase installation, refer to the document:
