220 vs. 110v SWG

[donaldm823]

I've noticed that at least one of the SWG systems is 220v. I'm going to assume that it's being imported from Austrailia.
I see the need to rework my power as an avoidable expense.

Is there any reason why you would need 220v to generate chlorine?

I think you will find that all of them are 220v since most use 220v to power their pool pumps (lots cheaper). But also, most SWGs, give you the option to rewire via jumpers at a terminal on the SWG to convert to 110v
