Guy;
We have an Outback FX2524 inverter. 2500 watt at 24 volts. Pure sine wave. Very nice unit.
I don't run much off it compared to some, anyway.
I run the output to 5 breakers that control circuits as follows:
1 has 2 freezers and intermittent shop tools on it.
1 runs the house fridge, an answering machine and the house Sat TV receiver as well as the house TV when power is available by switching which outlet the TV power strip is plugged into.
2 for my office power 1 for each of 2 walls of outlets run from the inverter. These have intermittent loads like computers, network hardware, etc running off them. As well as a couple of devices that run 24/7 for my network hardware WIFI access points, the office TV equipment, etc. And, of course, on cruel, hot sunny days I can run the window AC to cool off the well insulated office and not drain the batteries too bad.
1 dedicated outlet for use in the garage next to office for things like my wire feed welder, table saw or other power tools that pull hard to start. They benefit from the short, heavy cable run to the other side of the wall and start better.
That is 5 outlets and I seldom pull even a KW of power other than surges, according to my logs.
I never, ever use less than #12 to wire outlets and prefer #10 these days to avoid issues with voltage drop but devices for #10 are not available at Big Box Stores in case you try to use #10 be sure the devices can accept it. #14 is for speakers or phones, IMHO not power cable.
Just what we do. Probably more than you wanted to hear but there it is.
