12 volt amp requirements of a new FC

I have a new 2014 Flying Cloud 20' "Bambi" and have just added a Tri-Metric meter to keep track of the power use of the rig. Also have added a new PD three stage converter charger and will soon have the solar system in.

But I have been playing with the Tri-Metric and have some interesting data for you numbers freaks out there (like me). Here is what I have measured for power draw on the various items in the new LED lighted FC.

Amp draw for things in a 2014 20' Flying Cloud "Bambi"

Measured with a Tri-Metric meter and 100 amp shunt.

Water heater, when flame on: .74 amp

Refrigerator, flame on: .32

Refrigerator fan only: .55

Bed lights, reading, each: .17

Bed lights, overhead, 3: dimmest .1
brightest .52

Main overhead lights, 6 dimmest .23
rightest 1.18

Step light: .06
Scare light (floodlight) .13

Table light: high .62
Low .31

Kitchen lights (either, there are 2) High .38
Low .19

Bath lights (2, each with high and low) All .72
one high .38
one low .19
Every LED light inside on at the same time: 3.9 amps

Fantastic fan, each: High 1.55
Medium 1.22
Low .93

Bath fan (little, 4" round) 1.5

Kitchen range fan: 2.4

Kitchen range fan lights (halogen) 3.5

Furnace, 18,000 btuh, direct vent burner on: 3.65
fan only: 2.9

Radio, all off, no lights showing: no measure
Radio, disco lights on, no volume: .7
Radio, lights on, medium volume: .9 to 1

Propane detector: .06
(note: mis measured and posted an error recently on the forum, I was off by a factor of 10)

Pump: (variable speed) 2-4

1000 watt sine wave inverter, on, no load 1.76
with TV and DVD plugged in, but not on: 1.76

TV on and DVD playing: 3.6

TV on DVD playing, + radio on for sound: 4.9-5.3

Very small microwave, supplied by inverter: 89

Toaster, supplied by inverter: 75

Apple Mac Book Pro, charged running from
inverter: 3.1 to 3.3

Sorry if the amp numbers don't line up well, the table didn't transfer well.

Note the lights are very low draw, the radio can be quite high, the inverter takes a fair amount of power if on and not operating. When the TV and DVD player are on, using the radio sound system, the power draw is fairly high.

And, yes I can make toast and run the little microwave (from Goodwill, and old tiny one) on the 1000 watt inverter for short time periods.
