Avenue 29RL inverter installation

[DET29RL]

You are correct, If you are installing without an auto transfer switch, hook your inverter wires into these connections. You are going to need different connectors to allow the extra wires for the inverter.

I am installing with an auto transfer switch. If you are going this route you need to wire the transfer switch with feed in and out and the inverter as the alternate feed. I am also installing a 3000W inverter and will be pulling in 10/2 wire (if Alliance didn’t make it impossible?). You must know which wires are line and load to install the transfer switch to work correctly.

Do I disconnect the two and only connect to the outlet side and leave the shore power connection capped?

Below is how I wired my inverter and transfer switch. Note that the transfer switch energizes when connected to shore power/generator. This will disconnect the inverter output, effectively taking it out of the circuit. If nothing is connected to trailer's power cord, the transfer switch will drop out and place the inverter into the circuit.

Did you have to pull an additional 10/3 wire from the electrical panel shore power to the front storage area to add tobthe transfer switch?

I had the inverter prep on mine. Based on your picture, it looks like you have it too. I had to add one short romex run from the output of the inverter to the transfer switch.

Regarding the loop, one romex is going to be hot (from shore power) the other is going to be going to your inverted outlets. You open this loop and connect one input of the transfer switch to the hot romex. Then wire the inverter output into the other input on the transfer switch. Connect the transfer switch output to inverted outlet romex.

Note: Many high power inverters have an integrated transfer switch. In that case you would just open the loop, wire in the inverter, and connect the DC power to the inverter.

Also Note: On my trailer not all outlets are inverted, only the ones shown on my drawing.

Does your inverter run the microwave?

Did you install a 30 amp automatic transfer switch or a 50 amp automatic transfer switch?

Does your inverter run the microwave?

No, Alliance did not make the microwave part of the inverted outlets on my trailer, only the four shown on my drawing.

Do you have a 29rl?

Thanks you as you have been a big help....

The way Alliance did the inverter prep is fairly simple. They installed a junction box in the front storage compartment that has connectors inside. The Inverter breaker in the panel is pre wired to selected outlets in the camper. I checked living room TV and bedroom TV, end of island and both sides of bed tables are on this circuit. One must find the feed from the breaker and that connects to Line (Shore/Generator Power) terminals on auto transfer switch, other wire in the box connects to the Load Side terminals to feed your outlets. When you are on shore or generator power this will be the normally closed contacts in the transfer switch. You will need to run a new 12/2 wire from the auto transfer switch to the inverter. When you are disconnected from shore power the contacts for shore power will open and inverter contacts will close. My transfer switch states Generator on these terminals. Important thing is to never allow the inverter to be back fed AC power. It will damage the Inverter!

For what these RV’s cost, they should come from the factory with a charger/inverter installed? It would not cost a lot of extra money at the initial build stage and I would not mind paying the extra up front. Charge me the extra cost to do it right while being built! I relate RV’s to Harley Davidson, how much $$$ can we get from the customer after they buy that new shinny penny?
