Thanks @Kawak! The fuse is indeed busted and it has a spare fuse in the fuse box. I just replaced it and I it's up and running again. Thanks for you positive and quick feedback!
Hey guys.
My Ellies Inverter/UPS 1440W is stuck in 'Backup Mode' and the alarm keeps on beeping.
For some reason the batteries ran flat over the weekend.
My troubleshoot so far:
I made sure to unpluck any devices from the backup plug on the Inverter/UPS, plugged it into Eskom power on the wall...
