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?
Update: with regards to the Low SOC setting not being honored, according to Bluetti support, this is expected behavior. I know it says that in the app, but this seems extremely problematic and counter to how the system has been advertised. As it stands, the system will frequently (in my case, daily) drain to zero and then, just as problematically, charge from the grid during peak times. Adding insult to injury, if an outage were to occur when the system was low then it obviously wouldn’t be available as a backup. Relying on Backup mode could potentially address these problems, but then wouldn’t allow for peak shaving.
This all seems unnecessary as the Low SOC setting should be a fairly hard (I realize not exact) stop.
What am I missing? Are other folks just rolling with their systems draining to zero and hoping no outages hit at that time?
