Hello:

My KH 10.5 just got pushed firmware Master 1.70 and my inverter does not work anymore (thinks there is a grid fault when there is not, possible other problems too like EPS output from battery is not steady either). Anyone else received this version? Thanks.

still this I guess, not fixed: viewtopic.php?t=3016

Can anyone please send me master v 1.60 I can put on a usb stick and update tonight?

Master 1.60 and Manager 1.58 was mostly working. Only updated due an issue and Fox support said I was not on current firmware so they would not help!

On EPS port, with manager 1.70 voltage is varying wildly from 210v to 240v (only a brief sampling because my house was not liking it). Luckly I have a bypass I can power house via grid.

So, v1.70, cannot use grid and cannot use battery (EPS)!

@Will

Any chance you could send me master v 1.60 for KH10.5 I can put on a usb stick and update myself tonight?

I just need to know the folder structure / names inverter is looking for and the file. My manager was not updated so still 1.58 and my slave is 1.02.

I am so ready!

OK, this little disaster seems to have been caused by a failed update leaving the inverter in a partially-functioning state.

Though my installer started the update then became unavailable with any responses starting at about 4:45pm , about 5 hours later FoxESS support picked up the email ticket chain. I think that person re-applied the update to Master 1.70 then it started to behave again. He subsequently put me on Manager 1.66, slave remains at 1.02. Then he looked at my battery versions and said they should be updated.

(will update post when I see new versions)

(all S's the same)

I guess the grid fault issue with KH that started at 1.64 maybe has been solved.

This was a frustrating day.

Fingers (and toes) all crossed for you.
Watching with popcorn from my 1.60 version.

I got a FW upgrade notification today through

Master 1.60 -> 1.69
Manager 1.58 -> 1.64
Slave 1.02 -> 1.03

Have to see how they perform

So they just spray different version to different people. Indeed we are beta testers every time.

I was now offered 'slave' 1.03 in my app, so I did that to be all on the latest.

My battery versions are old though and Fox support said several attempts to update failed. I'd like to get these all on USB so I can have them as rollback sources for the future, and maybe I can get the battery versions newer also.

Yup, fire off random upgrade here and there... look at support tickets to see which get's the most reports
