I'd like to put an inverter in our 2460 Regal. I'm not completely clueless
when
it comes to electrical, but I'm not sure about all the options and
installation
issues. Can you point me to where I can learn what I need to know?

I'm thinking I want a 2000W with 3500W surge. That should handle a small
microwave or coffee pot. I notice there's a no-load drag that increases
with
the wattage.

Here are a few of my questions:

Can I fix it so that it's got an on/off switch but automatically kicks off
when I
go to shore power?

Are there any special features associated with a marine-specific inverter?
I figure GFI might be one.

Are there any models you would recommend? Any web sites to find out
about how to do an installation?

My batteries are going on 4 years old. Should I bail on them before they
start giving me problems? I've thought about maybe seeing if I can find
room for one battery that's bigger than the installed one so that I'll have
a
little more reserve. Is this a good idea? Is it practical?

Are there any other issues that I should be aware of?

Thank you, Michael

I put a 1000 watt inverter (2000 watt surge) in my trawler. Perfect
size, operates everything. You don't want to operate a lot on batteries.

It will run the coffee pot, but a kettle on the stove is better. The
thinking is, instead of getting a big enough inverter to run your
biggest load, you do not use electricity for your biggest loads.
Heating elements are battery killers.

I use the microwave, and anything else I wish. I'm good for 3 days at
anchor using everything, refrig and all. House batteries, are 2 8Ds.
#2 is one 8D for starting only. You don't have room for that many
batteries. What do you have, group 27s?

Can I fix it so that it's got an on/off switch but automatically
kicks off when I go to shore power?

That's called "automatic switching". One switch alternates between
inverter and shore power.

Hire yourself a good marine electrician, it's well worth it. There are
a couple of books at the book store, "The 12 Volt Bible", and others.

Thank you for your comments, Jim. I'll look into THE 12 VOLT BIBLE.

Yep, sounds right. The 2000 watt inverter should do nicely. You would
probably do fine on a 1500 watt unit as well. Neither one will allow you to
make coffee and microwave something at the same time, but the 2000 watt unit
will be more likely to allow you to keep coffee warm and microwave at the
same time.

The easiest way to rig this is to buy an inverter that is also a battery
charger and you will get the cross over function for free. I have a
"Xantrex" inverter/charger. If there is shore power then it passes the
shore power on to the output. If there is no shore power then the inverter
kicks in and provides the power. Mine even has a "load sharing" function so
that if the load is drawing a lot from the shore power it will back off the
battery charger so that it won't trip the circuit breaker.


Are there any special features associated with a marine-specific inverter?

I don't know of any GFI functions built into the inverter itself. Just
wire the inverter output to a GFI outlet.


Are there any models you would recommend? Any web sites to find out
about how to do an installation?

I am very happy with my Xantrex Freedom charger. It is a "modified sine"
wave output, which is better for battery efficiency but could create
problems for some equipment. My microwave, coffee pot, TV, VCR and various
chargers (cell phone, camcorder, etc.) all operate just fine on it.

Installation is pretty easy in concept, but can be a real bitch in practice.

You need to isolate the outlets for the devices you want powered by the
inverter. With luck this will be a single circuit breaker on your
electrical panel. With slightly less luck it will be more than one circuit
breaker. With bad luck you will need to rewire your boat.

It should be obvious what you DO want on the inverter: microwave and the
outlets for the coffee pot.

What may not be obvious is what you DON'T want on the inverter: Battery
charger, water heater, refrigerator.

You will want to mount the inverter as close to the batteries as possible
but NOT in the engine compartment. The farther away from the batteries the
larger the wire you will need to connect it up.

Speaking of batteries, you will want big ones. A 2000 watt inverter can
draw about 200 amps from your battery. At that rate you will get about 10
minutes of operation from a standard 27 series battery.

The inverter will generate a fair amount of heat and will need cooling so
don't bury it in a spot that will become an oven .



My batteries are going on 4 years old. Should I bail on them before they
start giving me problems? I've thought about maybe seeing if I can find
room for one battery that's bigger than the installed one so that I'll
have
a
little more reserve. Is this a good idea? Is it practical?

What do you have for batteries now? If those are good golf cart batteries I
wouldn't bail on them yet.

For a 2000 watt inverter I would recommend a minimum of 400 amp-hour battery
bank. I would also recommend a separate battery for starting your engine.


Are there any other issues that I should be aware of?

Keep in mind that the inverter is probably not "Coast Guard" certified and
can not legally be installed in the engine compartment. You probably
wouldn't want it there anyway because of the heat from the engines could
seriously damage the inverter.

You will definitely want to be able to turn the inverter off. If the
inverter is mounted some place that is awkward to get to then you will want
a remote panel to control it.

Neither one will allow you to
make coffee and microwave something at the same time

I'd bet the farm anyone who would even think this way is the guy who
always has battery problems.

Think this way? I don't understand what you mean.

I doubt that most people realize how much current a coffee maker draws when
it is making (versus keeping warm) coffee.

I use my inverter for making coffee all the time. I use it for the microwave
a lot too. Occasionally, especially when there are two cooks in the
kitchen, we accidentally attempt both at the same time. The inverter lets
us know it isn't happy and shuts down.

No problem with the batteries.

Rod

I mean the guy has a 24 foot power boat, probably with two group 27
batteries. Maybe 100 amps, probably less.

Better use the stove for coffee. My opinion, you are welcome to disagree.

I was a bit rough, wasn't I? Didn't mean to be. I don't agree with a
lot of people's opinions on power usage. I say, why use electricity for
something that's done better without it.

Electricity for a coffee maker is about the worst, since you can make far better
coffee "by hand," either with a manual drip into a Thermos, or with a French
Press.
