AC is great for long distance and certain applications. DC is great locally. The bridge rectifier should be between the grid & the home battery, not between the home battery and the devices it is recharging and/or powering.

The exception to this are high power home applications: Stove, Oven, Microwave, Toaster, Fridge, Dryer, Washing Machine, Dishwasher. The battery charger can be on the same circuit set.

Note that TV is NOT on this list. All video screens can be low power these days. All lighting can be low power. There is no reason why this can't be a simple 5V, 4A circuit with USB compatible plugs, several to a room.

You really think a small fraction of executives have IT Skills?

If there is a small fraction then it is so small as to be non-existent. The last executive I met who claimed IT skills kept coming down to the IT department and asking us to answer lists of questions, sometimes it was "Can I get someone to write a C++ program to do XYZ?" where XYZ had nothing to do with the job. Come to find out, he was working on a degree in CS and was having the IT group do his homework.

25 years in the field and I have yet to meet an executive with anything more than the basic windows user skills. The bulk of them consider dual core systems with 2gig of ram and 500g of hard drive space as "Top of the line Desktops"

Im doing it on the enc28j60. It does not contain the tcp stack on the unit, you have to handle it in the CPU.

The current code uses 27,626 bytes (89%) of program storage space and 1,543 bytes (75%) of dynamic memory.

Handles web interfacing for the switch, network config, rebooting the unit, and offers a json API call for pulling current state.

That is a wired connection version. I am also working on one that uses the ESP8266 wifi unit which does have the TCP stack on it. That one is much smaller code.
