Question:

Good Day, From the Progressive Dynamic Website, Im interested in the Progressive Dynamic Power Center PD4045KV. The PD website indicates that that the PD4045KV Replaces PD4045K, PD4045LIKA, PD4045. On e-trailers description it lists the Part Number: PD4045KA. What Progressive Dynamics model number is e-trailer selling? Thank You

The Progressive Dynamics 4000 Series Mini RV Converter w/ Charge Wizard and AC/DC Distribution Panel item # PD4045KA is the PD4045KV. This power center has a 45 amp converter that works with lithium-ion, flooded lead acid, AGM, and gel batteries. It measures 12-1/4" long x 8-3/4" tall x 7-1/4" deep and fits a 10-3/4" long x 7-1/4" tall cutout.

What make and model power center are you replacing?

I am replacing a WFCO-8735-P, I realize I am going from a 35 Amp to a 45 Amp charger and will be upgrading the battery wiring from 8 gauge to 6 gauge.

@NickK Sounds like you're ready to go. The only other thing is the item # PD4045KA requires a 10-3/4" long x 7-1/4" tall cutout. So you'll need to make some minor alterations. The WF-8735P requires a 10.44" wide x 6.13" tall x 3.75" deep cutout hole.
