MPPT 100/20 dropping to 0 watts every 10 minutes

[Shawnrt (Shawn)]

Hi, I have been using a Victron MPPT 100/20 for the last 3 months. I got another portable solar panel so that I can run two in series, to change at 20 amps. All good. One is a Nextgen Ecoflow 160W panel, and new one the bifacial 160W Ecoflow panel.

What I noticed with the new panel is that every 10 minutes it drops to 0 watts, and then a while after ramps up again. Two other panels never did that.

Connected in series with the other 160W panel, and I still see the drop, but clearly other panel does not drop.
Same when I run them alone, bi-facial one drops every 10 minutes, but other one not
According to this link it’s normal, but I don’t think so, why does the other panels not do that?

You have probably found a thread that explains this.

The mppt will retrack every 10 minutes or so if it hasn’t had to by then for other reasons.
The only way to know if is is panel or connection problem is to troubleshoot by swapping them over.
