Some definitions would be helpful here.
I assume "hard start" is the regular 17 amp surge required by the AC-powered March pump plus (for instance) a Marine
Air 12,000 BTU unit. This, as far as I know, falls back to a 6 amp draw after start.
A soft start? Is that also a "smart start"? I get the sense that the Dometic device somehow lowers the need for 17 amps to the 13 amps or so that the Honda 2000 can provide on "full" (not "econo").
If it's less than the Honda Companion 2000 model, the Dometic device might allow us A/C at anchor
. Right now, that's not going to happen.
