Question:

I need to replace my OEM WF-8735P. I have a 08? Chalet, two Crown 6V 220-cr. 5 years with100 watt solar panel controller also. Now, with WFCO, no charge with anything, no 12v, no AC, got pump only to work with one fuse, others blow. And want lithium option too. PD 4045ka or 4000 series 35 amp?

Progressive Dynamics discontinued the PD4135K so the # PD4045KA is what you'll need to go with going forward. You'll most likely need to check the gauge of wire used to connect to your battery to ensure it's up to the specifications of the this higher amperage unit. You'll also most likely need to make alterations to the cutout hole to accommodate the new unit.

The # PD4045KA requires a 10-3/4" long x 7-1/4" tall cutout hole. Since the the WF-8735P requires a 10.44" wide x 6.13" tall x 3.75" deep cutout hole you'll have to trim the whole a bit taller regardless to swap it out.

This unit comes with an output mode switch so that you can set the converter to charge either lead acid or lithium batteries without having to purchase any kind of adapter. It's able to sense the charge level of the battery and work together with your solar panel system to keep the battery charged.
