I have a 14 foot travel trailer I built from the ground up based on the 1966 Aristocrat trailer. I am looking at putting solar, lifefo4 battery and an inverter on my trailer. I am a newbie and need help figuring out if my design is correct.
I am looking at adding one 12v 176AH Lifepo4 (4 - 3.2V 176AH cells), a 400w solar panel array with a 40amp MPPT, 2000 running watt generator, 2000w or a 2500w inverter and an automatic transfer switch. below is what my 12v and 110v loads are;

My 12 volt DC List consists of,
2 - 12v, ? amps, ? watts, run time on a hot day 4 hours, Ventline 14" rv roof vent 12 volt FAN (can't be much of an amp draw)
1 - Bathroom Light 12v, .1667 amps, 8 watts, run time .25 hrs per day
2 - Outside Lights 12v, 1.5 amps, 18 watts, runtime 1.5 hrs per day
1 - Water Pump - 12v, 8.8 amps, 53 watts, runtime 1 hr per day
1 - Range Hood - 12v, 18 amps, 216 watts, runtime .5 hrs per day
1 - Jensen Stereo - 12v, 9 amps, 108 watts, runtime 2 hrs per day
4 - 6" speakers ?, ?, ?, ?
1 - Laptop Charging - 12 volts I guess, 10.8 amps, 65 watts, charge time 3 hrs I think
1 - tablet - 12v, 3.33 amps, 10 watts, charge time 3 hrs I think
2 - Smart Phone Charging - 12v, 4.5 amps, 18 watts, charge time 3 hrs
9 - Ceiling Lights - 12v, .5 amps, 6 watts, run time 1.5 hrs
1 - reading light - 12v, .33 amps, 4 watts, run time 1 hr
1 - Flat Screen TV - 12v ? amp, ? watts, run time 2 hrs per day

110v DEVICES
1 - Window A/C Unit - 110v, 114 amps, 455 watts, run time 3 hrs per day

this is everything I have

i was thinking about adding a small microwave in the future. of course when I run off shore power and/or generator everything runs off 110v. So with solar / inverter (which I'm a newbie) I would like to run everything off the 110v 2000w / 2500w inverter and my lithium 176AH battery. Which inverter do you think would work the best when boondocking?

Let me know what you think
