How do I hook up inverter?

I want to have all the 110V sockets run off my batteries when I am not hooked into shore power. I see inverters that would allow me to do that. I've never done this before and am wondering what the difficulty level is?

What you are wanting can be somewhat more complex if you want to have every socket powered. It would involve adding a fairly large inverter that includes a transfer switch. In addition you are going to need to add several more batteries depending on your application. You could be looking at considerable expense.

What exactly are you wanting to power and for how long? Give us some more details and you will get more people to chime in.

Eventually, I would like to add solar panels and use my batteries without hooking up for a 2-3 days. Within those days, I'd probably use power for my TV, DVD player, laptop, microwave (occasionally), vent fans, and interior lights.

I will be out of my RV with all appliances turned off during the day, so the day will be used to recharge the batteries.

Have you considered starting out with a small ultra-quiet generator like an EU2000 and seeing if that meets your needs? I think you are going to need at least 4 batteries to go that long and run that much stuff on inverter power. Not saying it is not do-able, but you are looking at a pretty considerable price tag I think if you add solar to the mix as well.

I too have been thinking of a way to do this. Except the Microwave, because I know It draws a lot of watts. Everything else on my list (and yours) is doable with just a small 500 watt inverter which will operate off one or two batteries and be a lot easier to charge than a bank of four batteries.

If you are not willing to sacrifice the Microwave you are looking at probably a 2000W inverter, big cables, big battery bank, and lots of solar arrays. ($$$)

Either, way you would have to have a transfer switch and a way to isolate the converter from the inverter power. On my 22FB some outlets are shared with the converter circuit breaker.

Part of the problem with powering "everything" is that you really need a large inverter because you are putting it inline with your shore power. Your outlets will only be able to power as much as your inverter puts out so when you are back on shore, you could have trouble running coffee makers, etc if you dont have it large enough. Trying to break out some circuits can be a little more challenging and you have to be careful that everything still has the proper breakers. Also keep in mind that if you want to hook up everything, that you really need an Inverter/Charger and will have to do some additional rewiring. If you try to just hook up an inverter to your shore power, the regular converter battery charger will kick on and will try to charge the batteries at the same time as you are pulling from them (ask me how I know).

Take a look at this converter and pull up the manual. It shows typical wiring diagrams for doing what you are talking about.

Dont get me wrong, I am not trying to discourage you from doing it cause it would be a sweet setup! I have looked at doing it myself, but when I got into what would be required to do it right - the cost really pushed me back to a generator.

IMO, 12V to 110/120V Invertors are great for small electrical items. For example, a low wattage LCD TV or perhaps a small 110/120V corded drill. Or, a 110/120V laptop - that only has 110/120V connection.

For the large amount of 110/120V devices and their power drain (in the OP's long long list), I'd recommend a "super quiet" generator as well. For more details on a recent review, surf:

https://www.jaycoowners.com/showthrea...ight=generator

If it were my setup.... I'd puchase / install Super Quit Generator on TT's main Power Cord. When shore power is available, unplug the TT's power cord from the generator and plug back into short power outlet. And, the generator would be sized for all "turned ON at same time" devices - using their startup power wattage (not their average running wattage needs). And where possible, don't use high hungary items with other other high hungary devices at the same time. re: TT's AC unit and 12V slide motor at the same time. Way "too much" power demand at the same time.

Hope this helps....

I have a 2000watt/4000 surge inverter... I am sure anyone with total confidence and understanding of how to follow instructions can hook one up.. HOWEVER I feel this is one thing best left to the experts.. On my new trailer I hooked my entire solar system up ran the wires for the inverter but had Solar Mike at www.thesunworks.com hook up the inverter... better safe than sorry
