Has anyone installed the WFCO AD model?

I saw a three-month-old post from WFCO that said they are working on a model that will stay in bulk for 10 hours.

Can you use a Charge Wizard with the WFCO to force it into bulk mode? https://www.amazon.com/Progressive-D...02OR41UM&psc=1

The charge wizard boost override is intended for use with select Progressive Dynamics converter/chargers and won't work with a WFCO. I've never been happy with the WFCO performance which is why I swapped the OEM WFCO out for a Progressive Dynamics.

OCD is my other initials..!

I didn't notice how much solar you have available, but-
I initially planned on swapping out my converter to a LI compatible one but after over a year I really don't see much advantage, especially so if you have enough solar. My converter breaker is always off unless I've got snow on my panels and a trip coming up. And even if I only get 85% LI charge from my LA converter it's still 35% more than equivalent LA batteries can supply.

IF you haven't already, take a deeeep breath, and try your existing setup out, you may find it's fine as-is. And if it's not, let the OCD run with it!

I have 380W of solar. The breaker for my converter has been switched off since I did my test of what the standard WFCO unit can do with Lithium on July 18. The trailer has only been plugged in for 4 of those days, and when not plugged in the inverter is on. The lowest I've seen is 85%, although the 12V refrigerator has been off for more than half of the time. Still, it is summer, although here that means most days have overcast mornings and sometimes overcast all day. It will be interesting to see how it goes in the winter. I don't need to have the inverter on when the trailer isn't being used, just leaving it on because I can.

In winter I noticed about a 50% drop in solar output in Michigan with my flat mounted panels. Low sun angle, shorter daylight hours, overcast days. PITA to keep snow off of them!

We got snow a couple of times that stuck, once in 1972 and again in 2002! Of course we make up for it with rain (most years, not this one).
