If you'd do a little research you'd know that the Progressive Industries hard wire EMS-HW30C (and EMS-HW50C) already comes with a remote monitor panel that includes a bypass switch. You'd also know that switching the EMS to "bypass" does
not bypass the surge protection section of the unit - it's active
all the time and it's that circuit which can be destroyed by any signal that isn't true sine wave. The alternative EMS-LCHW30C (and the companion 50 amp version) don't come with this remote monitor panel as the display is on the unit itself and although one can add a PI bypass switch to this LC series it's functionality is exactly the same - i.e. it does
not bypass surge protection either.
As far as "worry" is concerned I'm not "worried" at all, just careful. This afternoon I completed my tests and confident now that my particular inverter is
not internally wired with a 60/60 centre bonded neutral output I added a G-N bond to it's output, just as I recently did to my Honda EU2000i genset, and confirmed that my EMS-HW30C does accept the output signal from either with zero error and properly outputs it to the trailer. So contrary to your assertions it's obvious one
can set their rig up with a Progressive Industries EMS and have it properly pass voltage out to the rig
regardless of whether the input signal is conventional shore power OR a genset or inverter outputting a true sine wave signal, simply by plugging the rig's main service cable into that source, no transfer switching required. The upside is not only simplicity of use but it also means the EMS's remote display is usable regardless of whatever the source power may be - shore power, generator, or inverter. I'd say that's a win-win. :B
