Xantrex Freedom SW 2000 using 220V - 50Hz transformer

Anyone have experience using a Xantrex Freedom SW 2000 designed for 110 V- 60Hz with a transformer from 220 V to 110 V and 50 Hz? The specifications in the users manual say 60 HZ with a nominal range 0f 55 - 65 HZ. Your guidance please.

I've used it with a step down transformer and 50Hz. I did set the max current draw on the unit low to avoid possible over heating. It has worked fine with months of use.

Thanks Paul L. Glad it has worked well for you. The electrician I spoke with here said the same about the current draw but he was hesitant to recommend it since the manufacturer didn't. I just received a response from Xantrex customer service and they didn't recommend connecting the unit to 50HZ for risk of damage to the electronic circuitry.

It's worked fine for us. Used it two seasons in NZ. Even if it caused premature death, that would be OK. I'd then buy a good charger/inverter that can handle international power and be programmed to the charging profile I want. Something the Cantrex doesn't do.

Re: Xantrex Freedom SW 2000 using 220V - 50Hz transformer

the charger should not work. it should shut off and stay in inverter mode. it's a function of all inverter / chargers (and all UPS's) to not pass through incorrect power. low and high voltage will do the same.

it's maybe possible to widen it's error range. but it will not be good for it.

buy a dedacated multi voltage charger. and then use the xantrax to produce 120v 60hz to power the boat in inverter mode. as the new charger keeps batteries up

i'm not aware of any multi voltage inverter charger.

It's the input I'm referring to. For example, Victron supports 45-65Hz.

I have used two Sterling multi-voltage chargers for over 5 years in Europe. Would definitely recommend that as an alternative. 100-220v 50-60hz in; 12v out. I have used step transformers to run AC’s and then only the continuous duty type.

Re: Xantrex Freedom SW 2000 using 220V - 50Hz transformer

When we bought our boat, there was an old Xantrex RV3012 charger/inverter installed. It was working and I saw no reason to replace it. I did install a Charles Marine transformer to drop the voltage to 120 Volts.

When we were preparing for our trip across the Atlantic, I had the same questions that you do and I contacted Xantrex about the AC frequency specs for the input. I got a very short response which, in it's entirety, read "Dear Steve Brown, It's best to use 60 hz. Having a 50 hertz frequency could damage components if there not rated for that frequency. Best Regards".

I ignored that advice and figured I would try it myself and replace the unit if it failed. Result - we have been here in the Med since June, 2015 and have been plugged into 50 Hz shore power close to 2/3 of that time. I have had no problems with the unit working with a 120 Volt 50 Hz input. It still works perfectly.

Just my experience with my old Xantrex. Cheers and best of luck!

Steve

xantrex 2 charger and its literature claims it analyses the input and adjusts accordingly
Mine is a 3 bank 20 amp imported from the US
it operates fine on 240v

I imagine your case is handled similarly

Most things are not frequency sensitive between 50 and 60. A synchronous motor, so a fan my run faster or slower.
