As the title says, 50% of the time I plug my system into a "240V" source, it's either split-phase 180 degree, or two legs off of a three phase system. I had to double check, and when I measured it was exactly what I thought, 208V across L1 and L2. L1-N on the AT was 104V and L2-N was 110V. Clearly not acceptable.
I require the new neutral created, to pass downstream to my multiplus-ii 2x120.
Has anyone come up with a solution to resolve this, without bypassing the auto transformer?
If your question is, "how do I deal with 208V circuits in campgrounds?", then the only options I can think of are:
By the way, I'm a little surprised you measured 104V + 110V out of the AT given a 208V input. Was the actual input 214V?
1. Was the initial idea before I found the AT. The Victron chargers have pretty low limits for max current, and I went with the AT instead.
3. Thought about this, might look into it.
I will verify the actual input voltage today and report back.
Actual voltage was 208V, and another source was 207V. I wrote down the wrong numbers, and today verified it to be 101V and 106V on L1/L2. There's a slight imbalance on both pedestals I checked, but they both did add up to 208V and 207V.
After researching some of the 208V to 240V transformers, they all explicitly say that it will be three phase 240V. I wonder if the AT would handle this accordingly (it seems fine) and the downstream multiplus ii 2x120 will be able to utilize the input being 120V-0-120V from a Y. I don't see why not, but would be great to confirm.
I'm not sure where you're finding those. You just need a single phase boost transformer 208V-240V. Multiple phases don't come into play (and aren't relevant for your campground).
