installing generator

Hey guys, I just scored a nice little portable 4 stroke generator that peaks at 2kw. I would like to make this a non portable unit and mount on my engine room will route exhaust outside. Can anyone point me on the right direction as of what steps I should take to add this to my a/c system? I'm not looking to use this gen to charge my battery bank would only use for some a/c I have on board in case my battery bank gets low. I currently have an inverter on my 2 6V bank and this does the trick the gen would be for a back up system only.

Thanks in advance

most people safely use these units up on the deck. I do not think they should be installed nonportable in the bildge. Dry exhaust right? A pigtail to your shorepower plug is the deal

Lots of portable gensets like that need to be slightly modified - the neutral "floats" compared to ground. Make sure that if it's not, you do it yourself. ABYC electrical recommendations call for neutral to be tied to ground at a single point - at the power source: on land for a shorepower connection, at the inverter (lots have an internal auto transfer switch to do this), or at the generator.

To be safe, if you have a shorepower connection, I'd install a small three-pole transfer switch to handle switching from shorepower to genset. Relying on remembering to unplug something just isn't safe in the long run

On the 'other' side of the genny, are you planning to install a flame arrestor and a bilge blower ?

Otherwise, the shorepower pigtail might indeed be ticket (esp as a backup) if you can turn off the battery charger and h/w tank.
