I need some help upgrading the firmware on our Goodwe ES.  According to the app it still runs firmware version 1 and it seems the app has less and less ability to update the settings on the inverter ("Setup Failed").

1.  Will an updated firmware allow me to change more settings through the app?

2.  If so, how do I update the firmware?  Internet searches has been rather unsuccessful.

Thanks

I have the same inverter and discussed and implemented a firmware update with the help of the support team at Goodwe. My problem was however different than yours (I had problems with the mppt's control behavior). There is 2 versions of the inverter. the older version serial number starts with 3 and the new version with 9. I have the older version. The firmware for the 2 inverters is because of the different microchips on their control boards different. Goodwe told me that they have stopped development of the old inverter firmware and send me a new control board with the latest firmware. I think it would be best for you to contact Goodwe and discuss your specific case with them. Your inverter has to be linked to their portal to enable the engineers to log on and evaluate what the best solution for you is.   

Thanks Fuenkli.  It seems we have an older inverter as the serial numbers starts with a 3.   Did you install the new control board yourself?  I'm wary of tinkering with something so expensive.

Do you have a contact at Goodwe that you can recommend?

yes I did. It is very easy. Goodwe will give you good instructions how to do it.

Awesome, thanks Fuenkli!

 

Update:  so I received an email from Oliver (Weiqun Shen) with files and instruction on how to update the Goodwe.  There seems to be a "master" and "slave" and the master updated succesfully but the slave not and now I'm stuck with a non-functioning Goodwe.  Is sent them the error message details and will see what they come back with.

What's interesting to me is that they said nothing about a control board, even though I asked.

Maybe he knows Jack s...

Update:  Goodwe got back to me and sent me a new update programme (using the same firmware file though).  I update the slave using this programme and the inverter is working again.  Thank goodness.

However, now I can't seem to connect the wifi anymore...

Ok, (hopefully) final update.  After a bit of back and forth with the Goodwe guys, I reset the wifi, set it up again, rebooted the Goodwe and it is now working.  It seems though, after changing some settings, I need to reboot the inverter for the changes to take effect.  This is a hassle, but fortunately I don't change settings often.

I am glad you managed to get the inverter going again. What firmware version do you have now (mine is 1212). Why is it a hassle for you to reboot the inverter? I find it very easy by just confirming reboot after you made the changes with the EzManage app on the cell phone.

Sorry for the late reply, was on holiday.

According to the app, the firmware version is 07X.

When I make changes to the settings, I can select "yes" when asked to restart and sometimes this works fine, other times I get "Setup failed".  I then have to shut down the inverter and start it up again.
