[RE-wrenches] My .02 - 12/24v garage door opener.....

[Dana]

Wow, this is flash from the past…  I had almost forgotten about running DC in a house or garage.

With todays inverter efficiency’s & costs VS. the cost of proper DC wire sizing, garage lighting?, & having to modify a reliable lift system, etc.

Is there really a cost savings in the longs run?

 

It’s a garage, are you going to need to run any AC tools, battery chargers? 

I mean it is a potential man cave, really now….

I have measured the energy used by a garage door opener on more than one occasion.  they draw a fair amount of power while operating, however. they don't draw power otherwise so the total energy is very low.  I am wondering if a low cost non pure sine inverter to AC operated off the switches which would be low voltage would not serve the same low energy use and reliability of a DC garage door opener

Hi all,   any recommendations where to find 12 or 24v garage door openers.    Can’t remember this coming up on the list beforehand.   It is just for a single car garage door.    Don’t want to use an inverter, usually better to go direct to a dc motor.

Once I have a suitable opener, I can design the rest of the system around it.

Thanks for any/all input.                               John Veix,     GoSolar Ltd,   N.Z.
