Not the best way to be trying to load test. Use cables with lugs you can bolt to the battery terminals.

No, I think it's done in the app.

I would at this point. Might try a factory reset first just for the heck of it.

MPPT current is never going to be more than directly measuring current out of the panel outputs with an amp meter. And for the purposes of testing used (or new) panels, this works just fine.

While he did not say what brand, he did say he has a soft start.

And also just got all of your personal data off your phone. ;)

I've used those before and had zero issues. The only thing is I had to reverse inputs to get the results I desired. I wanted it to fall back to the grid when my inverter was down.

Measuring current directly across a panel output is going to tell you the max current the panel can output (assuming you are doing this in full sun). Perfectly valid way to test used panels.

What are you using to charge it? Perhaps the charger is what is cutting off too soon. Or are you saying it actually shows the charge MOS opening? If so, then it should be giving you a fault in the status area.

What do your cell voltages read when charging stops?

You have the sum high voltage set to 13.8v which IMO is a bit low (I have mine at 14.4v). And the Daly BMB SOC needs to be manually "reset" too every once in a while to 100% because it is not super accurate (especially if bluetooth is set to stay on a long time).

They seem a little smaller than a typical 100w panel. Perhaps their rating is based off of the bifacial aspect.

Yes. Also once the battery is fully charged, you may have to manually reset the Daly SOC to 100%

While there may be cheaper ones, I really like the Vestwood for about $209.00. Has Bluetooth and low temp cutoff.

Sort of a contradictory statement, no?
