Automatic Transfer Switch
« on: October 22, 2008, 08:22:11 PM »
Good afternoon everyone,


I am wondering if there is a safe yet economical way to run some sort of automatic transfer switch.


I do not have anything hooked up as of yet, but do have a 1KW genny, controller and inverter (1500W 48VDC pure sine wave) -- still waiting on my batteries...


What I am wanting/hoping to do is when the inverter shuts down because of low voltage I would like a transfer switch to cut back to the mains and visa-versa when the batteries are charged again.


Most of what I am going to tie into the inverter it will not matter (kids rooms upstairs -- so if they loose their games oh well  ;0)) but I am hoping to also include my pellet stove downstairs so I can continue to have heat even if there is a power outage.


Any thoughts or suggestions would be appreciated.


Thanks.

Scott

looks exactly like what I am looking for -- thank you. I had found some items similar to this but did not have the ability to work "nicely" with an inverter.

You've been short-changed.  You have a 48VDC inverter but it doesn't have this feature built-in.  If you had asked for it when you were buying the inverter, you would have found one that includes it.  Outback, Magnum, Xantrex...

The Outback is in the plans. Just could not swing it money wise right now -- going to get it with tax refund money.

Hmmm... just wondering, if your on the grid why the batteries? Im guessing that your battery system will be to back up during a blackout?

I cant think of any other reason to be using batteries when you are grid connected.

Latronics in AUST sell a TF switch with 20mS change over time. 240V at 25 and 40A I think.

I won't be grid tied to begin with. Will run upstairs and my pellet stove off the batteries. The outback I will purchase come spring will be the unit that pulls it power from the batteries (GTFX3048).
