Thanks, Scott. My converter should be delivered tomorrow. I’ll let you know my results. How did you mount the converter? I’m glad the guy I bought the transit from ordered the heavy duty alternator (250 amp) and dual AGM batteries. The factory wiring from the two 40 amp upfitter switches didn’t look big, I’d guess 10 gauge, and I will be putting the two of them in parallel. Think that will be good enough? So, would the current draw from the AC200P be the same whether the converter output rating is 15 amp or 20 amp? If so, I’ll seriously consider getting the 20 amp one depending on my results. Know of anybody else trying this?
@jkennon …I received my converter today and have been playing with it for about an hour. I ordered the 10 amp, but they shipped me the 15 amp which is a good thing. I think the 10 amp would have simply gone into auto overload and shut down.
I am getting a 573 watt charge rate and even though my input cables are fairly large, (I am using an 8’ extension as well on th input) the wire is generating some warmth but not bad. With my Isuzu trooper idling, the alternator would not output sufficient amps to keep the battery voltage from slowly dropping. If I ran the engine at 2,000 rpm I had plenty of amps to maintain this charging rate with the input voltage running around 14.4 volts. Just turning on the headlights and AC dropped the voltage to 12.43 while charging.
The 15 amp 12 volt to 48 volt converter is running considerably warmer than the 24 volt version I ran previously. If I were seriously going to rely on this for fast charging on the road, I would probably get the 20 amp model in the hope that while it is running, the % of operating capacity is lower which should generate less heat. The voltage converter put out a steady 47.95 volts even down as low as 11.5 volts input.
I would say the biggest challenge with the install would be having sufficient wire capacity to feed the input side and I’m sure you have a much stronger alternator in your rig than my Trooper.
Here is what I ordered even though it states 10 amp capacity, they shipped a 15 amp.

Update been charging about 90 minutes. Converter is hot enough on the bottom that I cannot keep a finger on it for more than one second. Started at 37% and now at 88%. Unit is running fine other than getting hot and the cables are all fine with no real temp elevevation probs.
