Onboard Charger vs. Smart Charger

So I have the standard WFCO 8900 series charge/converter (I believe it's the 45 amp model). However, I have a "smart" charger that I prefer to use. It just seems to do a better job charging and maintaining.

Can I bypass the WFCO when I'm using the Honda 2K and just use the smart charger directly to the batteries so as to not suck power from the generator when running the A/C? The generator noticeably kicks up and sometimes goes into overload mode when the WFCO charger tries to start charging the batteries.

  • I don't see any problem with that. You could just unplug the wfco from the 120v outlet and abanon it in place. WFCO is junk anyway, add to that a long wire run and you have batteries that never get a full charge.

    Edit: You probably still need the WFCO for the converter function, so if it's not on a seperate breaker, you could wire up a 120v switch and just turn off the WFCO when you want to use the smart charger. Running both chargers at the same time could interfere with the smart charger.
