I'd have suspected that they use inductive current sensors wired in parallel to get the combined current draw from both lines, but perhaps they measure individually and only show one at a time on the 50A unit, or some other setup
Using both on a 30amp 3wire system gets the same reading assuming you add the L3 to L1 jumper. That provides false voltage to the voltage sensor. The "amp sensor" is simply a amp probe type reading so it is the same also.
Funny thing. The man from PI suggested I always use the 50amp connection if available with an adapter because it provides more available wattage... My understanding was the available wattage vs used(30 in my case) maybe was cleaner/more efficient in certain times when loads vary. He also said to check both for the best voltage supply. In peak demand times the 50 could be better or 30 depending on who is using what. It was interesting. I will get a good adapter to check it.
After installing mine I got 117 on each leg and 9 amps(converter) and 17 amps a/c and converter.
I also got code E10 which is surge failure. It was after 10 so I quit for the night. As Google noted I would need a new board. Wondie. I will call them next week and see. I need to turn the breaker off and recheck. I was sweaty and tired so I gave in after I cleaned for a bit. Funny I got no sparks or anything when I plugged up. Makes me wonder if I messed something up.
