I currently have a 'hybrid' system comprising of:
SolarEdge Inverter, Victron Engergy MultiPlus-II, Byd B-Box Battery and CCGX controller
I am waiting for approval to export back to the grid, which can take up to 6 months in South Africa. In the meantime I want to control the charge rate to the batteries such that the charge rate is limited to the amount of surplus energy I have available from the solar panels.
I believe the relevant parameter in the CCGX controller is available under:
Settings -> System Setup -> 'Solar Charge Current Control' - Is this correct?
Unfortunately this is set to OFF and I have been unable to change it. Is there another setting I need to change to enable this? The current firmware CCGX is 2.33.
I am fairly comfortable with Modbus so writing the control loop isn't a problem but I am stuck with enabling charge control in the CCGX.
All suggestions gratefully appreciated.
