question

@billyblak, while there have been a number of reported instances of the load output malfunctioning, including several from my own customers, so far nearly every one that I personally have dealt with has been found to be caused by user error; ie, the "streetlight" function being left on (which changes the behavior of the load out and associated settings) or the jumper being left in, which can cause system conflicts if the jumper-defined settings are different than the app-defined settings, or a 20A load being attached to a 15A port... things of that nature.

I once thought I had managed to reproduce the load-out errors on my test bench, but after much trial and error I finally determined that in fact I was simply failing to take into account the shutdown and restart timers built in to the device - generally 2-minute shutdown upon low-voltage and the same timer upon reaching the restart voltage... +/- about 30 seconds.

Bottom line: my company in particular has ~137 customers using the load-out of the 100/20s as you describe, plus another ~237 using the load-outs of the 75/15s, and a grand total of 7 of our customers have reported problems in the last year. In 5 of the cases, I was able to positively identify the issue as user error. I haven't heard from the last 2 recently, so I'm uncertain as to their final resolution, but in general I'd say that so long as you fully read the instructions, connect the devices as appropriate, and understand all settings and limitations, you're fine to use the 100/20 as described.
