Inverter wiring setup

[lafester]

Hello all. I am new but have read many posts on this subject already and wanted to post my setup idea here to see if it sounds right.

My rig is a small Fleetwood Prowler 717B hybrid travel trailer.

99% of my camping is boondocking.

Battery is a new Duracell Ultra Marine size 31 (115 amp hour). Planning to upgrade to 2 golf carts in a couple years but that will require a whole new battery storage solution.

Converter is Itelipower 9100 40 amp (with smart charger) about to be wired to it's own circuit. (15 amp breaker)

I am pulling the microwave on to it's own circuit. (15 amp breaker)

A/C has it's own circuit but am not sure of the fridge yet. Hoping they are on the same. (20 amp breaker)

There are only 4 outlets left on on the last circuit which I want to power from shore (30 amp) or generator (20 amp 2600 watt) and inverter (10 amp auto switch/1200 watt). (15 amp breaker).

I am purchasing:

AIMS Power PWRIX120012S 1200W Pure Sine Inverter with Transfer Switch

High Quality 1/0/4/8 Gauge ANL Fuse Holder + 2 Pack Nickel 150 Amp 150A Fuse

Space Age Electronics SSU-PAM-1 Ssupam1 Relay Encapsulated

Already have:

2 gauge wire for battery hookup
4 wire romex from a house project

Plan is to run 2 gauge to the power side of the battery shunt, then from the battery side to the negative battery pole removing the old higher gauge wire (approx 2 feet total). Then run 2 gauge to the 150 amp fuse and then to the positive battery pole. I believe I also need to run a ground wire from the inverter to the frame.

Then pull the romex from the breaker to the outlet chain and replace with a romex line running to the power in on the inverter. Then remove that unused romex line from the outlet (first in chain).

Next wire the power output line from the inverter to that outlet.

I want the converter to auto switch so I got the space age relay (120 volt 10 amp). Hook up the black and white wire to the outlet breaker that is now wired to the inverter and then pull the black wire on the converter breaker and run it through the relay (always off wiring). Not 100% sure on this setup.

Hopefully all of that makes sense. Price is the main factor here and for pure sine wave this is the cheapest per watt for a name brand inverter and as a bonus has the transfer switch.

Just looking for feedback on the setup, also would like to make a bypass for the inverter for when/if it fails but not sure how to do that. I realize I can just pull the in/out romex and nut it together if things go bad but would like avoid that if possible.

I know for my battery power this is overkill but am planning ahead, and smaller does not really mean lower cost in this case. I have a remote start generator and battery monitor so I can fire it up easily when the amps/volts get low.

Hi,

How many watts is the microwave? I doubt a single jar will be able to do much more than warm up a cup of coffee.

It sounds like you have the circuits worked out. Do you have a particular question?
BTW, I wouldn't install the relay, choosing a manual switch, instead. Alternatively. using another breaker to power the converter. I just spent a few days and wore out my cuss-word load for a month, investigating a fuel pump relay in my Son's Subaru. Relays are another failure point, IMO. You may wish to have that convenience, no harm.
