I mounted my inverter in the pass-through storage compartment at the front. From there it was less than 5ft to the batteries. You need as short a run as possible from the battery to the inverter. Also, others who have commented on battery drain are correct. If you only use a single 12v battery, battery drain will be an issue when using an inverter. I have 2-230AH 6v batteries and solar to recharge in the morning. I've been extremely happy with the setup.

Thanks sorry for so many questions, but are you then saying that you plug in your shore cord to the inverter? When you say that you have an auto transfer switch I don't understand.
How are you getting the inverter to the outlets in the trailer? Is that where your breaker panel is?

If you want to just plug your shore power cord into the inverter you don't need a transfer switch. Just plug in and you're good to go. I didn't want to do that. I ran 12g wire from the inverter's output to the power centre in the trailer, thus the need for a transfer switch. I was looking for something a little more integrated, as we rarely plug in to shore power. This way when we need 110v, I just flip on the inverter using the remote switch that came with it.

Ok I have done a great deal of research on this set up and have purchased the material to complete the install on my fifth wheel this weekend. I thought I had it all figured out and had a plan in place until I started reading this thread. My brother in-law sells and installs renewable energy systems everyday and I have never heard of having to shutoff all the power to the appliances as people are saying in this thread. I will make a couple calls tomorrow to find out the best way to connect the inverter up from my brother in-law who is an electrical, my father and my close friend who are master electricians. I have attached a link at the bottom of this post for reference and videos as to how to hook an inverter up. I have an automatic transfer switch, a 2500 watt pure sine wave inverter, 2 deep cycle batteries, weather proof NEMA 4 junction boxes as well as proper cable and connectors to complete the install. I will let you guys know how it goes when I am done. Wish me luck.

Hi KootenayWC,

Are you agreeing that you need to shut off the breakers in the panel as mentioned earlier in the thread or do you leave everything the same as if you were plugged into shore power?

I am not sure if I understood my brother in-law correctly now after reading this thread. I plan on hard wiring everything into the existing electrical system using the automatic transfer switch and inverter. I spoke with the dealer and he said I was all good to go with the install.

Cheers

If your inverter is powerful enough you can run the whole RV. I've even heard of guys running the A/C for a short period with a BIG inverter but the draw would be immense and the batteries would last only minutes. When we talk about shutting off breakers for appliances we're thinking about smaller inverters that can't handle the loads, saving the batteries by not running 110 appliances on battery power that could be using gas ( fridge and electric water heater) and especially not running the converter ( trying to charge the battery with the battery doesn't work). Another way to avoid having the inverter power things you don't want is by using a sub panel to isolate the circuits you want to power with inverter. I have no room for a sub panel so I didn't go this route.

Remember that watts AC = Watts DC (with a small loss inside the inverter).

A 1200 watt appliance (coffee maker for example) will use 10 amps of AC; BUT when drawing through an inverter you will need (at 12 volts) 100 amps.

Read about Peukert Effect as well.

Thanks for clarifying that for me. I was missing the reason for shutting down the converter. Thanks.

So I have a few pictures to update everyone on the status of the inverter and auto transfer switch install.


First a picture of some of the equipment and tools I used to complete the install.

Next I had to remove the double light switch for the through storage light and the light by the king pin hitch. This was removed so I could cut the hole to install the inverter.

Once the switch was removed I made a template of the inverter out of cardboard and cut the hole for the inverter in the 3/4" plywood between the through storage and the factory battery storage compartment.

This was the best location I could find for the inverter due to the close proximity to batteries and the 12 VDC terminals for the camper DC power supply. (I removed the original 12V battery when we bought the camper last summer and installed 2 new 6V golf cart batteries in the front storage compartment.)

The Go Power Automatic Transfer switch is installed behind the finished wall in the through storage compartment. (I forgot to get a picture of the transfer switch install location to post. I will do that when I go to the fifth wheel next time.)

I removed the converter/charger from under the main electrical panel and installed it inside the factory battery compartment with the inverter and tied it into the transfer switch as per the schematics supplied with the Go Power Auto Transfer switch.

I have a few more things to do in order to put the system in operation. If you are interested I will post more pictures and description of the work I complete as I go. Hope you enjoy the post!

Bottom line on power is Watts = volts x amps x power factor. If a 120V appliance, such as your CPAP, draws 10 amps on 120V it will draw a little more than 100 Amps on 12 volts. Make sure the wires are plenty big enough and you have a large battery bank that can supply 100 Amps for 8 hours.
