I may be wrong but is there a primary (alpha) and a Beta principle in inverter generator synchronization? They do not use the finals as a reference signal do they? Using finals would be risky interconnect cord vulnerability wise. If they use an intermediate signal, where and how would a person tap into an inverter circuit to find a readable signal? Heavy emphasis on doubt...
Honda and Yamaha use finals. Champion, I think, uses intermediate. Kipor originally used finals then switched to intermediate after Honda sued them. I'm noticing a number of newer "off brands" using finals. Makes me wonder if either the patent has run out or if they're paying royalties. The gist of the Honda patent is that a unit in the slave mode compares the phase of the current and voltage waveforms, using the result to adjust the frequency.
