That's the difference between 14.4 and 13.6
Note the 20A 'smart' charge @ 14+v exceeds the 13.6v/35A wfco.
What does East penn suggest, 30% of C20 or 150*.3 = 45A
45A charge until battery V = 14.7v
hold 14.7 @ battery for hrs
float 13.8v
http://www.eastpennmanufacturing.com/wp-content/uploads/Renewable-Energy-Charging-Parameters-1913.pdfthere is always this from PD, fast means high current to 14+v, hold 14+v
14.4v boost, 13.6 'normal', 13.2 float
WFCO theroy of operation:
"If the converter observes no significant variations in current draw for approximately 44 continuous hours, it will drop the output of the converter from 13.6V to 13.2V."
Ask why 44 hrs before float.
