CHANGING A 220V INVERTOR TO A 110V

[shaun1]

Hi all.

I have a 220v 2000w inverter on my catamaran and now i am cruising the states and am trying to find out if it is possible to convert it to 110v.
I don't want to use a adapter as all my wall plugs are wired from the inverter.

Do any of you fellow cruisers have any advice for me.
I'm a toolmaker by trade so if you have any machining questions ill trade you.

Smooth sailing and Tight lines.

I don;t believe it can be done - at least not affordably.

The other issue is that the wiring to the outlets is likely too small as the amperage will double with the change to 120 volts.

There is an old Internet expression for this -- RTFM.

You will need to find (or download) the manual for your particular unit and see whether it is switchable or not. Some of them are, and some of them aren't. If it is not switchable, then you will have to change it.

But I'm surprised you would need to -- did you throw out all your AC gear just because you arrived in the States? The beauty of supplying your AC power on board with an inverter is that you can use whatever power you can find to charge your batts, then feed your AC equipment with the same nice 230v or whatever power just like you have back home.

Most battery chargers I have seen will accept any kind of power (some of them need to have jumpers switched over). And if your battery charger won't take a different voltage, you can buy an isolation transformer which will convert the voltage (but N.B. not the frequency) for you -- i.e., step up 110v power to 230v so that your battery charger can use it.
