WFCO WF-8955 amps in absorption mode
I have a WFCO-8955 (55 amp) that absolutely will not go into bulk mode even though it’s a 3 stage converter. Not sure if it’s inadequate wiring or an inadequate converter. It’s always 13.6-13.8 no mat...

Strange thing is the manual cryptically says "although the converter is outputting 14.4 VDC, you will not be able to read that on a voltmeter due to the voltage-current relationship".
The WFCO trigger is to get voltage at the converter to sag down lower than 13.0 volts during the first minute of charging. This is virtually impassible without imposing a large load on the battery as stated above. If I hit my system with a 100+ amp load from the inverter for a few seconds the WFCO will go to boost mode every time.
To the OP: The 25 amp portable charger is an excellent solution and should serve you well.
