SmartSolar 100/20 Load Momentarily Disconnecting.

I have the above solar controller. My caravan is connected to the load, the most I've had on the load is 10amps, so it's not that causing the disconnection BUT.......

When the sun fades and the input from the PV drops, the charger switches off, at this point the load is switched of for a split second and reconnected, it does this every day.

I've just downloaded the latest App for Android, and I've installed the latest firmware for the 100/20.

The problem I have is, when the disconnection/connection occurs, all my lights in my RV come on, so if I'm not there, I'll end up with flat batteries, and if I have to disconnect my battery when I'm away, what's the point of having solar as it won't charge a disconnected battery.

I live in my caravan, so I'm here most nights, to sort the problem out, I thought I was Upgrading when I put this controller in as I only had a PWM controller, wired the same, but this controller seems to be a step back for me.

Can someone from Victron please sort this out for me?

Regards,

Paddy

Hi,

Just to be sure, you still have the problem with the latest firmware? The latest firmware version is v1.54. This version specifically fixes a problem with the load output shutting off briefly.

If so, can you store the settings of the SmartSolar in VictronConnect and post the settings file here?

Kind regards,

Hi,

The settings file and service report are on a google drive that I do not have access to.

Can you please attach the files to an answer here, by using the "upload file" button in the editing toolbar?

Kind regards,

Hi,

So I got the file. I see that the load output is configured for "Always on". Did you always have it configured like this? If not, do you see the problem when it is configured for "Always on"?

And do you still have the black jumper installed in the VE.Direct port (underneath the fuse)?

Kind regards,

@Thiemo van Engelen.

Yes, I've also had it on battery life algorithm too, but it keeps doing it.

The jumper is currently on pins 1 and 2, I've also had it on 2 and 3, and also taken it out and it still does it.

Nothing I do seems to work.

Hi, any news on this problem?

It's still doing it, so the problem hasn't been solved by the firmware update.

Really need this sorting out ASAP.

THANKS

Hi Thiemo van Engelen,

Thank you for your reply, I found a similar thread after posting this question and I downloaded the beta v1.54 for Android and it didn't do it today.

I only installed my controller 9 days ago, it came up with a firmware update, which I did, and the problem started that evening, that's why I thought It was the latest version, because when i went into settings, it said i was running the latest version.

I'll see how it goes with the beta firmware, and if it does it again I'll post my settings file here.

Once again, thank you for your reply.

Regards,

Paddy

Hi,

This problem should be solved with MPPT firmware version 1.56, included in VictronConnect version v5.40. Can you please test and confirm that it is now indeed solved?

Kind regards,
