Solar Controllers--Don't be a Sucker! :(
Just got to say it again, how it is we are sitting here for five months off grid on solar with no problems at all (third season on solar like this), using the non-programmable, non-MPPT, solar control...

Hours are the same, but amps are 5 to 8% higher with mppt (under typical conditions).
The graph with mppt flat topping is not caused by amps clipping but due to rising panel temperature reducing the mppt controller's voltage headroom needed for operation. Components: Kyrocera 130W, 12V panel and Blue Sky 2512i charge controller.
Edit, battery voltage held constant at 12.25 to 12.35V.

The hours are the same and the amps the same, so how can you have more AH? Confusing what is meant. ISTR Salvo got some "flat topping" of his curve using MPPT which would do that, but that had something to do with amps clipping so doesn't count?
What does MPPT vs. PWM look like for dawn to dusk? Those ends of the graph are of interest too.
