"Do you understand how PWM works?
A controlled serial connection from the array to the battery
Ignoring the older cheap junk controllers that did shunt operation
PWM is not that concerned about voltage drops.
Voltage drop equates to a loss of power to the battery which is always a bad thing
As mentioned, PWM can deal with a 5% line drop without performance loss (most of the time).
5% from my POV is a poor system design; anything more than 2 or 3% total line loss is poor design.
MPPT will have a 5% performance drop.
Please explain - some details please
It works like the simple PWM the buck conversion is not needed at lower input voltages. The MPPT controller should not be used in that specific example anyway
Please offer up some specifics - convince me - right now I do not believe
It's all relative, but MPPT needs the big cables."
Again - I need specifics as to WHY you believe this
Personally I do not believe it
