No matter the power curve, ya still gotta put all that energy back!
Yep, and the interesting thing about LiFePo4, is they do not require Full Charge or Floating... so one would have to re-think their solar charging set-up, and have it stop charging once the bank was at say 90%.
I don't believe in the "one size fits all" approach to solar, so I plan on switching things around, occasionally. For example, I won't need 280w of pointed mppt solar during the summer, so I will likely run one flat 140w panel on pwm. But come the colder, darker months, I will run 2 panels pointed mppt. It was considering the charging of lithium batts that got me thinking about dragging out the charging time to suit how much charging was actually needed.
