Controller efficiency is better at 48/48 than at 48/12 so why is there a lower amps rating for the Midnite at 48v (battery voltage, I ASSume) than at 12v?
If at 14.8v battery and the output watts limit is 800w can you ever see 60 amps? I think it would be limited to 800/14.8 = 54 amps but I don't own one to have noticed that.
My Tracer 2210A MPPT manual says its "rated charge power" is 260w/12v or 520w/24v and that the controller will limit charging current to the "rated charge current" (20 amps) However, 260/12 = 21.7 amps
Is the self-limiting based on the amps rating or the input power rating?
It says you can over-panel but at three times "charge power" you will fry the controller. So max panel allowed for my 20 amper is 3x260= 780/12v.
But panel is input and charge power is output.
