Replaced my WFCO8955!
Like a lotta folks, my TT (toy hauler) had a WFCO8955 that would never go into bulk/boost mode. With two 24 series batteries discharged to 12.2v the initial charge current would never go higher than 18-20 amps. Of course, 15 ft. of 6 gauge wire running from the WFCO8955 to the batteries certainly didn't help much.
After a week of dry camping in Yosemite with this setup, I decided this was the last time I wanted to put up with running my generator for 3-4 hours a day just to keep the batteries 70-80% charged. Initially, I was going to replace the WFCO8955 with the Progressive Dynamics PD4655 (a direct OEM replacement for the WFCO8955), but changed my mind and ordered the Progressive Dynamics PD9260C, 60 amp converter instead. The PD9260C is completely enclosed, includes a 110v residential power plug, has the Charge Wizard circuitry built-in, and is designed to support a more generic installation. The PD4655 is very similar to the PD9260C electrically; however, it's not completely enclosed, has some of the Charge Wizard circuitry on an external power distribution daughter-board, and the 110v input must be hard-wired. So, rather than replace the WFCO8955, I elected to install the PD9260C in the front of my toy hauler, only a few feet from the batteries. I had previously installed a pure sine wave inverter and winch in the same area, so I simply paralleled the output of PD9260C with the wiring I had already installed for the inverter and winch. This allowed maximum charge current to the batteries (shorter wire run), continued use of the WFCO8955 as a backup converter, and lastly, would allow me to quickly remove the PD9260C for use in another travel trailer in the event I sold my current unit.
Anywhoser, got the PD9260C installed yesterday. I now have 55-58 amps of initial charge current in bulk/boost mode---nearly triple what I was getting with the WFCO8955! Getting the same 50 to 70-80% charge that used to take 3-4 hours in about an hour. More quiet time--woo-hoo!
