Hi All,

I was hoping to get some info on running a US 110v 60hz boats on
230v 50hz shorepower. If a transformer is used to convert 230v to 110v I
think the frequency remains at 50hz and would like to know what equipment will
work at 50hz, battery charges, aircon, fridges, TVs, etc.

I see some US
boats are 220v 60hz and 110v 60hz, hows does that work?

Thanks
JohnH

It really depends on the equipment. You can buy chargers that will work on
50hz and 60hz, same goes for some aircon equipment. You'd have to research
what's installed on your boat.

Some washers/dryers will tolerate the change in frequency, but not all.
Hairdryers and space heaters and such things are usually OK.

Fridges, TV and other electrical appliances will generally not tolerate a
change in frequency.

A common technique is to put a big charger on the boat that will work on both
frequencies, and then use your inverter to power most of the appliances. The
charger simply has to be big enough to keep up with the inverter. That's the
cheapest and simplest approach.

John:

I had a 60hz boat that cruised Europe.

There isn't an easy solution. Here's what I did...

Many, or perhaps most, battery chargers will accept 50 or 60 cycle power.
Thus, I kept the batteries charged using shore power. Then, I ran the boat
off of the inverters. For cooking, we used a propane stove (which was
another whole can of worms). We did without air conditioning and started the
generator when doing laundry.

During our last year in the med I had the boat's wiring changed so that
shore power could be used to directly power the washer/dryer and the air
conditioning. I verified first that these would accept 50 cycle power. It
worked "ok". The appliances ran hot, and I burnt out the dryer.

So...

It is possible, and not really bad -- if you are ok with running the
generator when you want to run the heavy appliances.

If you will be in Europe for an extended period, then you probably want the
second solution I did, which is to split the power such that electronics and
perhaps the refrigerators, run off the inverters (so that you get 60 cycle
power) while the heavy appliances run off of 50 cycle power (or the
generator).

Hopefully this makes sense.

Arild will probably jump in on this, but if I remember correctly, the
big issue is when you're trying to run "inductive loads" on the wrong
flavor of electricity. Mostly, this means "things with motors", and
includes your laundry machines, air conditioning compressors, and the
refrigerator/freezer compressors. Most electronics simply convert
incoming juice to DC anyway, and will tolerate wrong-Hz with little or
no ill effect.
