Plug and play for typical 120/240V electrical system

Discussion in 'Connecting to the Grid' started by Mark Zinn, Feb 27, 2012.

  1. I'm building a small micro hydro system which should be well suited to a single plug and play GTI to start with. I'm building it to be expandable, if everything works out well.

    I have an unused 120/240v. line (2 hots, neutral, ground) available and would like to use it.

    I understand most small GTI's are stackable, but can they be stacked on opposite legs of a typical 120/240v. electrical system , utilizing a common neutral?

    Thanks, all .

    Yes you can split 240 volt line. Black,white,green for one 120 volt line and red,white,green for the other 120 volt line. Black and red should be the hot wires.There are some other color combinations as what would be red might be blue or some other color. Best to check with AC volt meter for voltage. And one of those new cheap test lights or a neon one to make sure which is the hot wire.
  3. That's what I thought, would be the same as two inverters on two seperate 120v. circuits.

    Sometimes I don't see the forest for the trees.

    Thanks Tom!
  4. Mark,

    Can you post pictures of your hydro system? We have a spring fed stream that runs year round that we would like to make energy from.

  5. I'm still in the design phase. I've been collecting parts this winter, and will start assembling this spring. Pics and progress will be submitted. I plan on using the totally enclosed PMA sold here because of the wet environment.

    I have a spring fed stream that runs all year at approx. 1800 gpm through a natural necked down point where I plan to install a low profile undershot water wheel. At that point, the stream has good fast moving volume, and I can make it even better with about 100 sand bags. Sand and bags are cheap. I have no usable fall without encroaching on the adjoining property.

    My wheel is being made from a poly lawn roller tank with 32 pcs. of 1 1/2" x 2' aluminum angle epoxy attached. I chose this design because of the 3' wide, shallow, fast moving nature of my water source. The wheel will 'hang' from the center of a tall saw-horse type structure. This will allow me to counter-balance it so it will 'float' with the rise and fall of spring rains. The two upstream legs will also incorporate a trash rack to protect the wheel.

    I should be able to make 300-500w. We'll see.
  6. My future posts about ny micro hydro system will be posted on Hydroelectric Generators forum.

    Thanks all!
