@guystewart - You were getting an update for this. Any news?

Thanks,

Hi,

I have two PV Strings - 1 connected to a SmartSolar 100/20 and the other (larger) string connected to a SmartSolar 100/50. Whilst the 100/20 works perfectly well, the 100/50 controller occasionally does not restart charging in the morning. This may happen once every 5 to 10 days. I can get it going again by turning charging off then on and all will work fine until next time. If it does not start and I leave it not charging, then it may start charging again the following morning! There doesn’t appear to be any consistency as to when it might not start charging.

I reckon this started happening after a firmware upgrade about 3 or 4 updates ago. Each time I try to update to a newly released version I hope that it will fix the issue - but unfortunately not. It used to work perfectly fine for over a year. Both units are configured with exactly the same settings.

Is anybody else getting the same issues? Any suggestions?

Thanks!

David

Hi @davidp,
The internal ticket is still open, last note was re-assigning it to another engineer to investigate. I have asked for an update and posted this new thread to it.

@guystewart - did you ever get an update?

I’m fairly sure it has to do with the VE Network side of thinks. I removed from the network for several days and it didn’t have this issue. Two days after I added it back in, the problem re-occurred

Thanks,
David
