I'll try to update the MultiPlus 48/5000/70-100 remote (over VRM)....and he rejects the update with the error code 1391.....any thought why ?
I have had this happen a couple of times uploading an altered ve config file for an installation, I found trying again after a few hours helps (one site a whole day later). It is possibly a network/internet issue, or the installation is trying to upload VRM information. So it may not have stored or save correctly to the GX.
The other reason may be because the system restarts when updated and power to the internet router is cut off so no connection. Did it update at all? (it does uplaod to the GX device before updating so does not need for internet connection to be successful) Sometimes my remote configs were successful even though the error comes up.
Note if you have a VERY early model of a CCGX - these unit cannot be used to update the firmware remotely, this coulds be your Issue - its below a certain serial number that this issue occurs, It could also be that try again will work if the serial number is higher - but My guess is that your CCGX serial number is a early version, and you will not be able to update the multiplus' Fw remotely
Thank you Guys....I was trying to upload the latest firmware, den Inverter is quite new...but I'll try it again when I'm around (not remotely). The access is over the Cerbo unit (there, the firmware upgrade was remotely possible). Keep you posted !
The MP must have a minimum firmware version number of 426. If below it wont work . Not sure if it will attempt to or not https://www.victronenergy.com/live/venus-os:remote_ve.bus_firmware_updates?fbclid=IwAR3I2kcfqKnH70t1m4VUuHrvqCGIFbLVQoWEKyO05Aw42ps5Or7WLJWb4Y4
Additional resources still need to be added for this topic
