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…. ---------------------------------------------------------------------------- Dana Orzel Great Solar Works, Inc.

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 On Jan 31, 2018 2:39 AM, "John" <[email protected] <mailto:[email protected]> > wrote: 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.
