GlennWest Posted February 18, 2019 Report Share Posted February 18, 2019 I been researching inverters and for the life of me, don't see where Victron outputs 2 120v legs on a single unit. Magnum does. Or am I missing something?

GeorgiaHybrid Posted February 18, 2019 Report Share Posted February 18, 2019 You can run two Victron inverters in a stacked configuration to get split phase 240 power or use a Victron auto transformer to convert single phase 230 to split phase 240 power (120-0-120) Quote 2017 Kenworth T6802015 DRV 38RSSA Elite Suites2016 Smart Prime Link to comment Share on other sites More sharing options...
GlennWest Posted February 19, 2019 Author Report Share Posted February 19, 2019 Thank you. Didn't know about the transformer.

oldjohnt Posted February 19, 2019 Report Share Posted February 19, 2019 Glenn, there are simple relatively cheap ways using a common generic "dry transformer" (if such is available??) to get 120/240 Single Phase Three Wire out of a 120 VAC single phase source be it a Victron or anything else. If you had say only one leg of straight 120 VAC available you can use a transformer that steps that up to 240 VAC Line to Line equipped with a center tap Neutral. That way you end up with the same as a residential 120/240 Single Phase Three Wire with two 120 legs and 240 Line to Line. Assuming any transfer method switches the Neutral you would configure the dry transformer (I'm talking about an isolation transformer here not an autotransformer) as a Separate Derived Source using a Bonded Neutral. Obviously the dry transformer needs the correct specs, such as say 120 VAC Primary in and 240 Secondary out with a center tap you use for Neutral PLUS it needs the required power rating DUH. Or use a Victron Autotransformer as discussed above (Im unfamiliar with them) if available and it does the job ?? and compare prices etc., IE do your homework and make YOUR choice John T Quote Link to comment Share on other sites More sharing options...
GlennWest Posted February 19, 2019 Author Report Share Posted February 19, 2019 Single unit is much less wiring and simple. But I want whole camper to run on inverter. Magnum just goes to 4400 watts. That is why I was researching Victron. Thanks guys.

Deekon Posted June 9, 2020 Report Share Posted June 9, 2020 ? So to make a 240v split phase would a victron 24v 5000w 230v linked to a transformer do that? Quote Link to comment Share on other sites More sharing options...
GlennWest Posted June 9, 2020 Author Report Share Posted June 9, 2020 Victron 230v units are 50hz. I read one can change that with software. That unit is made for the Europeaan community. And yes, with all VIctron to get 240v 60hz you need a transformer. That is why I decided to use Magnum Pae units.

Victron makes inverters capable of 240 volt 60 hz operation. It can be done with two 120 volt inverters run in opposing phases with one being a master and the other a slave or with a single 240 volt capable inverter. There are many people who use Victron inverters to produce 240 volt 60 hz power.

oldjohnt Posted June 10, 2020 Report Share Posted June 10, 2020 (edited) Glenn, I don't have the specs or wiring diagrams for any Victron units you are considering. That being said, do any of the appliances you will be using require 240 VAC ??? DO YOU NEED 240 ??? I ask because many 50 Amp RV's just use two legs of 120 (perhaps one AC on L1 other AC on L2) and nothing requires 240. Subject to how an RV pedestal is configured if it had two legs of 120 THAT WERE IN PHASE (NOT 180 out like typical 120/240 single phase three wire residential) there's a risk the Neutral could be over loaded. If a person were to use two separate 120 VAC Inverters, one for each leg in a 50 amp RV, they need to be synchronized so each is 180 out of phase with the other. If two legs of 120 are 180 out with each other you end up with 240 L1 to L2. In pass through hybrid inverters they are synced with the utility power. As I noted above one option (if available) is the use of a dry transformer (perhaps Victron or another???) that has a 240 Volt secondary winding having a center tap, which is similar to your homes transformer, thus providing two legs of 120 each 180 out of phase with the other and 240 L1 to L2. Again, if you were to end up with two legs of 120 that are in phase, there's no L1 to L2 240 and there could be a Neutral issue. PS In the electrical power distribution trade where I practiced at least, this is called "120/240 Single Phase Three Wire" instead of split phase. A single phase motor might be called split phase as it has a start winding and a separate run winding........... Maybe talk to Victron for advice, they know this stuff better then I do for darn sure John T Too long retired this is getting over my pay grade lol Edited June 10, 2020 by oldjohnt Quote Link to comment Share on other sites More sharing options...

GlennWest Posted June 10, 2020 Author Report Share Posted June 10, 2020 (edited) Been this morning comparing using 2 Magnum 4448 vs one Victron 10k 120v and a autotransformer. With all the connections needed for two inverters, I had decided to use an E Panel for simplicity and cleaning up the wiring. Also need the artr remote to link the inverters together. Well my cost now is very close to Victron with transformer, <200.00. A lot simpler and way less connections. I may would build a bypass for maintance also. Have not figured on a remote for the Victron. Now I can go with 120v or 230v Viictron.

Lou Schneider Posted June 10, 2020 Report Share Posted June 10, 2020 (edited) You're looking at about $500 and 30 lbs of weight for a 4.6 Kw 240 to 120-0-120 dry transformer, and you'll have a cobbled together system. I'd just bite the bullet and add a second inverter if you have any 240 volt loads, if you don't just use a single 120 volt inverter and configure it to feed both sides of the breaker panel in parallel. Neutral overload isn't an issue as the maximum inverter power is 5000 watts, or 42 amps. It's no different than plugging the RV into a 30 amp shore power feed, except you have 5000 watts available, not 3600. Or let the Victron only feed one half of your power panel and leave the other on shore/generator power. Move the circuits you want to feed with the inverter to the inverter side and put the ones you don't want on the inverter on the generator/shore power side.

GlennWest Posted June 10, 2020 Author Report Share Posted June 10, 2020 (edited) Sounds like you are not a fan of autotransformers. Victron pushes them for getting both legs hot. Please explain. I also need 240 for my mini split.

GlennWest Posted June 11, 2020 Author Report Share Posted June 11, 2020 (edited) On the pkys website, they state a way to wire multi or Quattro to get 240 180 degrees apart. They show bringing in ac/shore power L1 to hot line on master inverter. L2 to neutral connection on slave unit. Then neutral line split to neutral on master and hot leg on slave. This just don't seem right to me. If this right sure save a lot of connections.

I was thinking about the input side for the single inverters and 240 volt. To get 240 volt on the output side you need two inverters like I listed or an auto transformer. You can however get 240 volts 60 hz with either method.

GeorgiaHybrid Posted June 11, 2020 Report Share Posted June 11, 2020 Glen, just buy a seperate 240 inverter to run just the mini split and the other 120 volt inverter to run the everything else.

Now that I know YOU DO NEED 240 I can narrow down your choices to these 1) Use two 120 VAC Inverters, one for L1 other for L2 that MUST BE 180 OUT OF PHASE WITH EACH OTHER to get 240 L1 to L2 2) Use a dry Transformer that has true 120/240 Volt Single Phase Three wire output consisting of a 240 volt winding that has a center tap similar to how a utility transformer works. It would feed your regular RV 50 amp 120/240 Panelboard 3) Use an Inverter having true 120/240 Volt Single Phase Three Wire output IE L1 & L2 are 180 out from each other so its 240 L1 to L2 4) As noted just above, use a 120 to 240 dry transformer for the Mini Split There may well be other methods I missed, but this is enough for now LOL Now its YOUR money YOUR choice how to proceed Let us know your decision John T Quote Link to comment Share on other sites More sharing options...

Much simpler that way. You open up another problem with that. Ok, run seperate line for Cassette. This would be a much smaller wattage. Then a 120v inverter to my eletricsl panel. Also my cassette, which is my 240v, wire at panel box goes upward, not downward. I reused the factory ac line. It was right there. Just attach to it and change breaker. Soo there's not enough slack to pull down to basement.

GlennWest Posted June 11, 2020 Author Report Share Posted June 11, 2020 Researching last night on dual Victron inverters and came across Amsolar website article on this. They state dual Victron inverters have peoblems with shore power like this. The pass through doesn't work. If this so, I will just go back to Magnum units.

GlennWest Posted June 11, 2020 Author Report Share Posted June 11, 2020 (edited) yes, we chatting on facebook. He uses the transformer for his 30 amp service when he has to and for his generator. PM Steve Dixion and he uses a relay to redirect 30 amp to a dc power supply feeding a PT-100 solar controller.
