Have installed a 30A hardwired Hughes Watchdog. Didn't put in a "switch" (aSSume you mean a switch to bypass the SP) but will be doing it soon. Found out that the SP would kick out when running AC on generator due to voltage dropping below (very momentary!!) the "protection" low limit. Since trailer is now on our own 10 acres (not travelling anywhere), only running when needed on generator, I have disconnected the SP so we can run the AC!! Hughes sees no problem with the unit, the gen mfg doesn't see any problem with the genny!! So, no SP being used at this time!!
Just thought I'd mention it to help with your decision!!
So, are you happy with your Outdoors "replacement"??!!
