Proposed Solar Charging Regimen (sanity check)

[Barry Fields]

Just curious, how well does waste-not PWM  work with LiFePo4? (close volt tolerance)

I did try the waste not with the lithium using the hawkes bay controller but it hadn't been implemented properly yet in the firmware and I haven't tried it again .
  There isn't much power to recover during the absorb stage since the lithium will take in 100% of the available pv in my system - instead of only a small part of it like with lead acid. That is why the lithium battery charges so much faster. Plus there is the 98 or 99% efficiency during charging. I think the diversion function may be a better option if someone wants to use pwm control.
I would want to be able to divert the pv before it gets to the controller to a direct dc load. I am not sure if the Aux diversion could do this and still let the controller supply loads on the system. It seems like it should be able to do this though.
