The internal transfer switch stopped working. The system was setup such that when the battery voltage reaches 48V for 5 seconds the internal transfer switch brings in the utility to power the loads. I loaded the ESS assistant settings in the inverter as an attempt to bypass however I don't see the menu options for the ESS on the CCGX. I also have no option but to advise the client to switch manually. I need some assistance to resolve this issue.
Please advise, which respective firmware versions are you running in the multi, and CCGX?
Try upgrading the firmware to the latest firmware 469 and the latest ess assistant. as one of the earler versions did not show the ess information in all senerios
if you have the assistant installed then the ess information will appear in the ess selection area on the CCGX
All connected devices had the latest firmware. I tried resetting to factory default, reprogramming, latest firmware update but none of that works. The correct voltage is confirmed to be present on the input as well. There is a sound of the inverter trying to switch over but it doesnt make the transfer.
