Old Xantrex 60 150 controller

Power went off while doing firmware upgrade. Unit not seen by combox. Is there a way to bring it back? Any and all help will be appreciated. I have been trying to kick myself but I don't  reach. Help!!!!

You did not see the warning that the inverter would cycle? Maybe you were kicking

Combox had various updates to recover from this. What version is combox?
The older versions required you to have the old firmware still. Do you still have it?
If yours is new enough, you should still see it if you hover correctly in the firmware update section.

Combox is out of support and was replaced with the gateway. Gateway will not allow this to happen.

The other thing here for others is, there is very little reason to change firmware on mppt-60-150. It has been totally reliable for offgrid since it came out. There are revisions now but I doubt you need them. There was one revision in 2006 or so that added a scroll mode (my suggestion) so my non skilled users did not have to push any buttons and the mppt would scroll thru the vitals like, current state of charging, mppt output, system output solar, hours/minutes in float, and a few other parameters. It is a nice feature as the controller can double as a system display and you can have an SCP or gateway at another location.

The combox is fine. Still working. It's the charge controller that it's missing in action. It has amnesia and it's not seen by the combox.

What I wrote is for your mppt !
