The only experience I wasn't able to accomplish in our first season as a cruiser was a true overnight on the hook. We spent about 20 nights out, but always at a marina or slip with hydro. All because the Admiral is a bit of a nervous sort and has an insane fear of all of our batteries going dead and us being stranded, even though I've patiently explained how the battery switch with separate battery banks works and how we reserve the starting battery for starting only.
So....my only other alternative is to pick up a portable generator/inverter as a back up.
I know there is a whole other discussion on the safe use of portable generators on boats, I've got my head around that.
My question is, I have a 3 bank 20 Amp ProMariner Prosport onboard battery charger that is rated at full draw for 20 amps, so at 110V, about 2200 Watts. Specs below.
The generator brand I am considering is available in either a 1000W (900 Continuous) or 2000W (1750 Continuous) both at 15 amp of course (well, probably actual is around 13.7 I would think).
My preference is the smaller unit based on weight and size. Slightly cheaper too, but that's not the primary consideration, the difference is only a couple of hundred bucks. My cooktop is electric and draws 1500 watts, so the smaller gen wouldn't allow us to use that on the hook, but we're ok with that, always have a BBQ with us.
So my long winded question is, will the smaller unit be adequate to feed the charger, even if it takes longer to charge? Or do I need the 2000 Watt model to not cause issues with the charger? And for those of you that have/are using portable gen's, what are you using?
