The product being used Omega2S+ Pro carrier board
Device Firmware Version: 0.3.3 b247
Description of the issue:-
When using Omega2S+ Pro with USB power and a LiPO battery as a backup, the Omega resets when the AC power supplying the USB power adapter drops out.
For context, we live off-grid in rural NSW, Australia. We are using the Omega2S+ Pro boards for things like power monitoring and generator control etc. Our main AC power comes from a battery and inverter solar system.
Expected Behavior:- We would expect that if the AC power supplying the USB power adapter drops out that the Omega would continue to run normally.
Observed Behavior:- When the AC power drops out, the Omega resets/reboots. However, if the USB cable is unplugged from the device the Omega runs normally on the battery without resetting.
Steps to reproduce the issue:- Simulate the AC disappearing by either unplugging the USB adapter from the mains or switching it off at the wall switch, this makes the Omega reset in my scenario. This is consistent no matter what is providing the USB power. We have tried the following USB power adapters Netgear, Apple, Samsung, and laptop plug pack that has a USB power output.
Could someone who does not live off-grid and has a stable AC mains supply try and reproduce the problem for me and share their results. This would help me rule out the AC power supply to the house being a part of the problem e.g is this related to the fact we using AC power generated from an inverter?
Also, if anyone else has experienced a similar issue and/or has any advice to share.
Any help would be appreciated.
