Installation
DC Coupled Charge Controller Preparation
Before a DC Coupled (charge current fed directly to the battery bank) renewable energy charge
controller is installed and integrated into the system, the following requirements must be adhered to:
•
All DC Coupled charge sources must be fed to the battery bank via an optional current shunt.
•
All DC Coupled charge controllers must have either an output that is activated when the charge controller
reaches Float or an input that triggers the charge controller to a Float Charge state.
•
The start-up and shutdown instructions
must
shutdown the charge controller CB before the main battery
CB is disconnected and start up must close the main battery CB before the charge controller CB is closed.
•
The SP PRO will not export active power from any DC Coupled charging sources to the grid, as per the
requirements of AS/NZS 4777.2:2200 appendix M.
•
DC Coupling cannot be used with a managed battery system. Contact Selectronic for further details.
Failure to install a current shunt or charge stage linking will reduce the performance and result in non-optimal
operation of the system, preventing accurate state of charge control or tracking.
For more detail on installing and integrating a DC charge controller, refer to the relevant document in the table
below, where the latest versions of all documents can be found.
