BE500G3 stops randomly but no power outtage

[Dantes]

I recently purchased the BE500G3 on Amazon. Intermittently, and without any power outages or fluctuations, the unit unexpectedly shuts off power to the connected devices and starts beeping. I only have two devices plugged into the Battery + Surge Protection outlets.
The most recent occurrence of such happened on 10/23/2025 at around 12PM local time. I live in an Silicon Valley area, California, the power from PG&E is pretty stable. 

This behavior is concerning, as the primary purpose of a UPS is to prevent loss of work during power interruptions. Instead, the unit is causing unexpected shutdowns and data loss, which defeats its intended purpose.

I understand the product includes a three-year repair or replacement warranty, and I am considering submitting a warranty claim for repair or replacement. Please advise on the appropriate next steps.

If the system is connected to a computer running APC Power Chute Software (PCPE / PCSS) provide the following logs for review: Event, Data, UPS, Diagnostics.

What is connected to the system now and the actual load (wattage)?
