Hi Drake, Do you have the AC coupling firmware in the Radian? It should be at least Required Firmware 001.006.070
This is a good place to start: http://outbackpower.com/downloads/documents/appnotes/acc_freq_app_note.pdf I have seen better results programming the Freq Shift Response Time to the lower end ie ~0.05s. Which micro version is it? Is it freq/watt capable? On Tue, Aug 25, 2020 at 10:09 AM <[email protected]> wrote: > P.S.
