I am trying to dial in maximum production on my system. I can regulate the amperage with adjusting the inflow to the batteries. This is the only control I have outside the automated processes of the MPPT of each string.

Above you can see I use string 1,2, and 4. Both strings 1 and 4 have 7 panels of of 650 watts panels. String 2 has 4 panels.

The Voltage power max is 44.56v. The Amperage max is 14.59. So my max string voltage is, in theory, 311.92 v.

When I set me resistance, which is max charge to the batteries, at 157amps, I am getting about what you see in the photo. When I set the max charge higher, i.e. 190 amps, I seem to be getting significantly higher daily production. It goes from about 38 kw to 56kw on average.

Here is the question:

Is this harming my panels by allowing this higher than stated Current max(14.59amps) on the panel data sheet? Will the panels, "self regulate" the amperage?…
