I'm looking at buying a used Thermal Arc 300S. The guy is selling cheap because he can't test it, so it would be a gamble. But he also says it's
208V 3-phase. I know the other, newer, inverters, like the LS300 can run on either 1- or 3-phase at that voltage.Does anyone out here know if the 300S also has that "Smart-link" or whatever they call it? The thermalarc.com website has no info on this whatsoever.
Thanks.
