I recently installed a AT1 Smart Panel with Apex 300s and BK300s connected via HubA1. I’ve encountered a number of issues with the AT1 not adhering to various settings. For example, in Backup mode, the battery discharges continuously unless I manually turn off AC/HUBA1 in the app. Another problematic example is in TOU and Custom modes, where the lower SOC charge limit (30%) isn’t honored and the batteries will continue discharging until I manually turn them off as they approach zero. I have other examples but these are the two most prominent issues.
Firmware is current and Bluetti Customer Care is looking into the concerns. I assume other AT1s are working as expected since I don’t see many reports of these types of problems. Any ideas what might be wrong?
