Eco-Worthy MPPT and Solar30 PWM Test
Did a quick backyard test of my two solar controllers using the actual trailer wiring etc as intended for camping with solar later this month. Got some blue sky, no clouds. The Eco-W on the 230w p...

Hi,
This is all a balancing act. The higher the voltage the less efficient the MPPT is. But the hotter it is--the higher you wish the panel voltage to be. The sooner in the day voltage is above 14.8 (for example) the sooner charging happens.
Does the amperage stay the same as the voltage drops from heat?
Does higher design voltage allow for better shading results? (I'm talking general shade of the entire panel.)
What will happen if BFL13 uses his PWM vs MPPT in the shade on the 230 watt high voltage panel? Which will outperform the other?
