How do I convert 220V to 440V?

The inverter for the machine requires a 440V, three phase power supply. My shop only has 220v single phase power. 1. Change the inverter to one that accepts 220V single phase- expensive and potentially complicated (I would imagine). 2. Use a single phase transformer to convert 220 to 440. Then use a rotary phase converter. Would this work?

How many powmr 5000W hybrid inverters are left?

Only 16 PowMr 5000W hybrid inverters with 80A MPPT Charge Controller are left in stock - order soon. These inverters offer a pure sine wave inverter DC to 220-230VAC, support utility/generator/solar charge, and come with a Bluetooth LCD USB control. They are suitable for 48v Lead-Acid and Lithium batteries.

Are 480V to 240V Transformers reversible?

Transformers are reversible, however, there is some loss that is accounted for when used for the stated step up or down. When you reverse the transformer, that loss is still accounted for, only in reverse, so a 480V to 240V transformer when supplied with 240V may not give you the full 480V output. This thread is interesting.

Can a 230V rotary phase converter be used as a 3 phase transformer?

Another option would be to use a 230V rotary phase converter and then step up from there with a 3 phase 460:230 VAC transformer wired backwards. One advantage of this is that most transformers have adjustable taps and this allows you to balance phases a little easier. And it seems these transformers are available as surplus for less cost.

Where can I buy a 220 3 phase transformer?

Now you have 220 three phase available, as well as 440. As for the transformer, there are usually a couple on Ebay al the time. You can check with local industrial electrical companies and surplus equipment dealers. Should be able to pick one up for $100-200.
