PD or Iota for my upgrade?

I never set the "three things" on my Trimetric, using it right out of the box. It reset when charging stopped at sundown when I had it monitoring solar so I changed that not to. Maybe a power interruption counts as a charging stopped, don't know.

It reset because the charging current dropped below the charging limit and the battery voltage was above the charged voltage limit. If the battery wasn't fully charged when it reset, they expected you to set the charged voltage limit higher or the charged current lower. At sunset, it should have dropped in voltage and been well below the charged voltage limit, so I wonder if it really reset at some point before then, when it was producing enough voltage to be above the limit and low enough current to be below the current limit.

They have a cycle history function that will tell you how high the voltage got before reset and how low the current got before reset. You have to be in the L3 mode to read those, but you can look back and see why it decided to reset. Using those values, you can tweak the reset parameters if you want to use that function. I can understand that many feel it's just as easy to calculate it manually, or you can force it to reset whenever you want to if you know the battery is fully charged.
