There is still a problem with the MPPT Can SmartSolar firmware 3.16

[ThomasManthey]

A year ago, I noticed that the solar controllers no longer functioned correctly after updating to the latest firmware.

Now, since I added a battery to my system, I also updated the firmware for the solar controllers to V3.16.

Then only one of the 7 SmartSolar controllers connected via Can was still working. Finally, I updated the GX device in my MultiGx to the latest version (3.51). Unfortunately without success. The behaviour remains the same.

Unfortunately, my account has also been deleted in the meantime and I had to register again.

So the only solution is the same as a year ago: downgrade to V3.13 ;-(

V3.13 yesterday, V3.16 today

Because I was already there, I tested version 3.15 straight away: It works “just as not” as version 3.16. Now I have all solar controllers running on V3.13 again and it works perfectly.

My system is now running:

Multi2GX V3.51

1x SmartSolar_MPPT_VE.Can_150_70_rev2_v3.13_A10C

2x SmartSolar_MPPT_VE.Can_250_70_rev2_v3.13_A114

4x SmartSolar_MPPT_VE.Can_250_85_rev2_v3.13_A116

@guystewart,

When can I expect a correction to the latest version so that I can also benefit from the improvements in the updates?

Until now I had assumed that the VictronComunity was supposed to be a knowledge base for all Victron users and therefore wrote the questions and problems in English.

However, with the changeover to the “new” system, my account has now been deleted and with it all chat histories. This means that I can no longer understand how to solve a problem myself, even if I have had it before.

Is it possible to get the chat as an export? There were a lot of interesting topics there that I would like to access if necessary.

Thanks for your help!

Hi @ThomasManthey,

All the older community content is archived here - https://communityarchive.victronenergy.com

Unfortunately the built in search is no longer working, but it has all been crawled by google, so you can find your original topics clicking here.

This was a once off, I expect it to never happen again. Apologies for the inconvenience.

Hi, @guystewart,

Thank you for your quick reply. Interestingly, Google does not find all the posts I have written, even with my name. However, I have searched for the content and have already found almost all of them. I had hoped that Victron would have recognised the potential of such a forum and not just have the costs in mind ;-(

It still lacks a sensible categorisation and a useful search function.

Now I will create a personal backup of the forum with “wget” just in case.

But what about the actual reason for my contribution?

Since my post of 20 May 2024 “Is there a problem with the firmware “SmartSolar_MPPT_VE.Can_250_70_v3.15_A109.xup” ?” nothing seems to have happened regarding the CAN problem.

Apparently there are also other problems with newer firmware: “MPPT Firmware 3.16 Issues”.

When can I expect the bugs to be fixed so that I can benefit from the latest improvements to the solar controllers again?
