Voltage vs. PWM controller & wire size
Ok, there is a recent thread out there MPPT vs. PWM and some post were a little confusing to me. Instead of hijacking his thread I started a new one. My set up is two 208 watt Sony panels with 28....

GD - I think his 10ga part of the rant was about "solar" part, i.e. from panels to batteries. Here 3% is fine with PWM. With MPPT it wouldn't affect the charging voltages at all - but 3% V-drop would mean 3% AH loss then.
