When is Desulfation Mode Active With PD9280A Converter

Question:

I recently purchased the PD9280A and the remote pendant. In your video, as well as in some literature, you describe 4 modes of the converter Boost, Normal, Storage, and Desulfation. However, the pendant only allows you to cycle through 3 modes. How do I know if it is in desulfation mode, since I cant manually select it? Also...and I probably should have checked this before my purchase, but I have 4 12V 125 A/H each batteries in my RV. Vmax SLR-125. In addition to my mode question, can you confirm the PD9280A that I selected was the correct choice? Thanks

The Converter Status Remote Pendant # PD92201 that works with the Progressive Dynamics Inteli-Power RV Converter # PD9280A does indeed only allow you to cycle through three modes, however, one of those is the Storage Mode, and the desulfation is only active when the Charge Wizard from the converter is in Storage Mode.

The desulfation mode is an automatic occurrence so you can't toggle it on and off with the pendant; it will automatically increase the voltage for 15 minutes every 21 hours, which is what is referred to by desulfation mode. I added a cut out from the manual which mentions this.

In regards to your battery bank, this converter is an 80 amp converter, which is plenty for your 125 amp hour batteries.
