VRM firmware update not working for VE.Direct MPPT - Error 1300

I’m having problems with VRM remote firmware updates. I’m on latest release v2.20. It's happening with a stable fibre internet connection, as well as 3G/LTE connection on two different modems.


With all VRM settings enabled etc…


Remote VEConfigure works OK – I can download and upload configuration for my multiplus no problems:


But the remote firmware doesn’t work most of the time – after a minute or so of this:


I get:


A couple of times it showed me a list of devices (very very rare) – sometimes incomplete, and still with a warning message:



But I managed to update two of my MPPTs that way… Also, I sometimes get, which I know is untrue:



During the scans my remote console goes like that – I guess this is intended?


Then after a few minutes it slowly comes back on:


The system is located in New Zealand, and the lag to victron servers is approx 400-500ms - could that be possibly related?



Should I try something else to get this working better somehow?

Hi, I’ll ask support to take a look. Is it ok if they login to your system for Diagnostics?

Yes, absolutely! I'm over 1000km from home, but within reasonably good internet coverage - most stable connection would be during European business hours (when we're parked for the night). VRM ID 16907.

The problem appears to be on a much lower level, it is not the firmware update feature itself, but in communicating with the USB-serial devices. I created a bug report and assigned it to my more hardware-savvy colleagues.

Thanks, let me know if you need anything. In case this is relevant - I'm only using Victron USB dongles, except for the USB hub.

What type of USB hub are you using? Is it self powered or bus powered? Are all USB cables of good quality and not unusually long (more than 2m/6ft)? Any other USB devices apart from the VE.Direct cables? That's probably enough questions.

The problem was sourced down to be particular to a certain type of USB hub. Its was solved by replacing it by something else.

The details, for example why with that particular USB hub (-chipset) normal operation does work; and firmware updates don't is on the list to be investigated by Victron.


For details; read the comment thread.

Have you tried to manually update this to the latest firmware now 2.23 and see if that helps.

I am using a wifi extender to connect to my Venus GX thus I am hard wired using RJ45 to the range extender. wirks very well for me. but then I only have the multi connected off that, and no other ve direct products.

anyway this may help and may not


I found My venus GX was very slow when using the internal wifi modem and very short on range


Good luck and I hope you get it sorted.
