Inverter

Has anyone installed an inverter in their FR3? I want to add a 1000W to ours but would really like to have a wiring schematic to show where the electrical lines are run.

Anyone have any ideas?

Thanks!

This should give you an idea...

Now, a few things that I know will get mentioned:

Yes, I realize I will have to unplug the converter/charger every time. I dont mind since Im already there (plug for converter is in the same bay).
Yes, I realize this will power every 120V AC circuit in the RV, including the AC. No, I dont intend to try running the AC off the inverter, this is mainly for the TV/DVD/outlet power while rolling down the road.
Yes, I realize I could replace the converter/charger with a converter/charger/inverter. I already have a Progressive Dynamics PD9280, which according to my research is a pretty good charger already, so Id like to keep it.
Yes, I realize an auto transfer switch would handle the plugging/unplugging for me. No, I dont wish to deal with one, Ive had more than one fail and its always a headache.

Otherwise, what issues do I need to address? I have an empty bay right next to the batteries in the MH, so the run of DC cabling and fuse will be ~3ft. From there, I intend to hard wire the 120V AC output to a NEMA 30TT plug that Ill put in the back bay next to the generator plug and label as "inverter".

Thoughts?

@cucamelsmd15. Have you installed your inverter as in your diagram above? I'm curious how it turned out.

Thanks!

I have not yet. With hustle and bustle of holidays, I plan on trying to tackle it in my time off around New Years before we head to Daytona for the 24.

Edit: Worth mentioning though, this is the one I plan on adding. Granted, you can run the microwave off of it, but nothing else at the same time, but I cant envision needing more than 1000 watts.

I do have a spreadsheet that I used to calculate the specifics of why I chose the 1000w over the 600w or 2000w if anyone is interested.

I started with the same goal as you (power the tv/DVR outlet). I hooked mine up by disconnecting the wires from the 110v breaker that fed the tv/DVR circuit, hooked up and sent 12v power to my 750 watt inverter from that same breaker then connected the wires to the tv/dvr circuit to the output side of the inverter.

Dear Batts-toy

Did you just run the TV/DVD always on the inverter or did you use some type of transfer switch to transfer to 120 volt when you hooked up to shore power?

I leave it connected that way all the time. Also I have 2 sets of 6 volts batteries (Interstate deep cell extreme 232Ah each) 2 in series for 12 volts then parrallel for 464 Ah, along with 288 watts of solar. DW won't go with me without her tv so I set it up this way for dry camping, I've only been out 3 days tops so far so I haven't determined a dry camp limit yet.

Thanks for the reply.

My wife and I both like our tv. Wouldn't leave home without it. I am going to put an inverter inline to my tv/DVD so we can use it while driving but will install a transfer switch so it will use the shore power when connected. My thinking is I don't want to be using battery while also trying to charge it with the converter. Might be too much on it. We don't do any dry camping and all I have is 2 12 volt coach batteries. We have a residential refridge that has an inverter for it and it doesn't last but 4 to 5 hours. I wish FR would have had the option for 6 volt batteries.
We live in the country but are city folk RVers.
We like our conveniences.
Thanks for your reply and happy thanksgiving!

I ran a circuit from the inverter to a dedicated inverter outlet near the existing 110VAC outlet for the entertainment center. I then installed a surge strip above the two outlets that all the entertainment system appliances (and out computer/phone chargers) plug into.

I just change the outlet I plug the strip into depending on the power source.

Went I ran the wire I also installed an outlet in the basement for an outside TV while dry camping.

I had considered something similar, but the ability to use other outlets in the coach, especially one on the dash near the laptop tray is appealing. Running the microwave is obviously a big help too.
