That would be the next test, connect the inverter directly to a 12 volt boat or car battery. There's no telling how much voltage drop there is in the wiring to your boat's 12 volt outlet.

What I'm not reading in your post is any mention of overcurrent protection. We can assume that there is a fuse or circuit breaker protecting the wiring to the 12 volt outlet but if you're going to wire this inverter to the battery, the wiring will need an appropriate sized fuse or circuit breaker within 7 inches of the source of power.

Because the resistance of the conductors matters more at 12 volts than at 120 volts, your best plan is to keep the 12 volt wiring as short as possible and extend the 120 volt wiring to where the crockpot or other load will be.

Re: Getting rid of alcohol stove

Thanks for the instructions rwidman! The cig lighters are protected by a 15 amp fuse, I'm in the process of tracking all the wiring down now. To be on the safe side, I'm going to wire into the cabin lights spot on the bus, also fuse protected, with heavy gauge wiring. I'll never use the full wattage of the inverter, so the fuse will be undersized to the wire and inverter. Best place for the weak link. Thanks for the thoughts,
Dan

The sickening stench of the fuel while trying to cook underway and the occasional flare-ups which, with alcohol, are invisible until you smell your hair on fire were just a total nightmare.



The only thing that I can think of which could equal its menace would probably be a British Seagull outboard.



Toss it.

But the hunters had non pressurized alcohol Orego stoves with oven. No smell no flare ups
They are actually really great stoves

Re: Getting rid of alcohol stove

Hooking up direct to the battery worked wonders! I've been enjoying lentils and split pea soup. Works great as a rice cooker too. The one fault is that the model I got doesn't get hot enough to take the crunch out of the lentils, so I've been butane-boiling water first to prime the cooked. Le sigh ...

Re: Getting rid of alcohol stove

If I wanted to cook lentils (which I would not wish to ever do) I would throw a pot on top of my origo stove, and in 5 min or so it would be boiling...

(Just to punny to stir the pot here... Couldn't resist, sorry)
