Hi there,
In an attempt to stop asking 156462 questions in a
single thread, I'll make a separate thread about this particular one.
I know
solar discharge can be a problem, draining
batteries at night. I also know diodes are what you need to stop this process. But fairly little information seems to be at hand about this.
Some sources say the voltage drop in the diode is usually more than the
power it saves by preventing discharge at night. I also find it hard to believe that the fancy
MPPT controller I got from eco-worthy wouldn't have such a dead-simple thing as a blocking diode in it's systems to control this...
So, long story short: in the typical 1-panel array, do you need a separate blocking diode yes or no?
