auto transformer 230vac 50 hz to 120vac split phase

[edgerly779]

I need to split phases on hybrid 230 vac 50 hz single phase line to create 2 120 vac lines for appliances, I am installing off grid solar. Already have hybrid 5kw inverter There is 2 120 vac lines and no neutral from inverter. Looks like I need a midpoint neutral transformer .

Looks like you need two inverters?

Thanks but looks like 120 vac input not what we have ours is 230 vac 50 hz input which needs to be split into 2 separate 120 vac outputs

Is your input 240v single phase or or dual/tri-phase?

I'm assuming its 240 1 phase so two hots and a ground wire? You need to run another line back to the box for a neutral wire (center tap). Neutral plus one of the hots should be 120v. Neutral plus the other hot will also be 120v, just the oppposite phase. Tru and keep the loads even on the two sides. One reason the 14-50R plug is so popular nowdays for car chargers is it has a neutral wire along with the two hots and ground so you can pull 120 or 240 off of it, vs the traditional 6-50 plug most 240v things like welders and such use.

Not sure if the power rating is adequate for your application.

230 with 2 lines and no neutral.

There are some relatively inexpensive options for single phase 240v voltage converters. This seems too cheap and easy of a solution, so maybe someone that knows what they are doing has an opinion.

240 with 1 hot

No,
240v= 2) 120v hots and a neutral each

^^ Not with this hybrid solar inverter

Instead of us playing guess WTF you have, what you want, and what your going to power, how aboutyou spell it all out and stop being cryptic and giving us info piece meal. Equiptment model numbers, specs, etc. So at this point, how do you have an inverter putting out 240 volts (is it AC or DC?) with just two wires? What is powering it? How many amps is it supplying at 240 volts? Is it one or three phase going in and going out? Do you want 120 1 phase or 3 phase?

I'm thinking you think you can split the phase of a single wire coming out of some sort of inverter. It doesnt work that way. Inverters dont work like transformers. SOunds like you want some sort of step down transformer but without more specs, nobody can help you. Sounds like you go the wrong inverter if its not putting out what you need.

^^ Not with this hybrid solar inverter

It is an opti solar 5kw hybrid inverter. single phase and supplies 243 vac 50 hz. I found only 2 that work growatt 5000 split phase 5000t-us or seaauto-tx-5000. Cheapest is 350 bucks. Victron makes one I think as well. Just seeing if there are other options. Inverter is already supplied just need this auto transformer to finish solar off grid install. I just downloaded wiring diagram.

240 v 50hz is european, US uses 60 hz. Your not going to run your laundry machine off this. The first hit I get on google about this is: https://www.ebay.com/itm/303761229715

Note in the description "( This inverter could not connect directly to a AC 240V/120V split phase power system in USA )"

That Growatt transformer sounds like what you need, it converts that 240 euro to USA 120v split phase.

[edgerly779]

^^ Correct must create a neutral since non exists from inverter. Looking for options hat do not cost a lot. seauto auto trans former hard to find now.

You need to to solve the 50 Hz problem, or none of it matters. That or buy European appliances.
