You should already have a WFCO three stage charger, so an inverter/charger would be an unnecessary expense and wiring problem. A 1,000 watt (8.3 amps @ 120 volts) inverter will run most things. If you plan on using the inverter to power many electrical motors, a pure sine wave inverter is best. If the inverter load is mostly resistive (lights coffee maker, toaster, TV, computer), a modified sine wave inverter will work fine. Rule of thumb is you need about 200 amp/hours of battery power for each 1,000 watts of inverter. Remember it takes about 10 amps of battery current to produce 1 amp of 120 volt A/C current. I have a 31 foot coach with two fridges, a portable ice maker, three TV and a satellite setup. I never see a load greater than 4.5 amps on my 1,000 watt Xantrex Pro watt inverter.

its true that while most of us want a sizeable inverter, its really limited by the size of your battery bank/battery hours. You could install a 3000w inverter, as some larger coaches have, and yet with only a single 12v house battery, the inverter would ultimately do no more than a simple 1,000w model - your battery bank will be a better determination, unless you are expanding the batteries as well.

you also could simply purchase an off the shelf w*mrt power inverter, in the tire/battery section, and have an easy 120v power option, with minimal cost and effort

Who knows - how many factory batteries do you have? Are they 6 V or 12 V?

tvs and dvd/blueray devices don't require much power, so the batteries should have no problem powering them the whole night, if you're an all-nighter type.

of course, most folks don't take into consideration all the 'other' 12v items that are being used while just on the batteries, also, such as lights, fans, the water pump, furnace, and normal draws from C02 and propane detector, etc., that also draw down your batteries at the same time.

So, answering your question is really an impossible task. Everyone 'uses' power differently, and the state of your batteries, the time you are using devices, and even the outside temperature all play a role in 'how long' batteries can do anything.

But, it's doubtful that only using a few 12v and 120v items during the evening hours is going to be any real issue for your batteries, when you are off-grid.

It's both a combination of your Inverter usage AND your 12v items that will determine your 'battery time'... and it's different for everyone, and even different every day.

I agree. If you have TWO 12 v or 6 V batteries in good shape abd fully charged than one TV and one DVD player should go for hours before you have any problems.

Just monitor your batteries every hour or so until you figure out what works best for you.

In installed the Aims 1200 watt inverter last summer in mine. I love it.
Best bang for the buck IMO. Works seamlessly with the factory setup (the way I have mine setup).

Model# PWRIX120012S 1200 Watt Pure Sine Inverter, Built In Transfer Switch.

It was only $169 on Amazon. I also purchased a remote switch for $25 and installed it all myself.

Do a search on this site this one and other inverter writeups.

that's right, as batteries are not a 'specific' output device like others, as far a time goes.
Your inverter will output 120v power, for sure, at least as long as you have enough battery power.
Your shore power will give you 120v power, normally, as long as it has power itself.
Your generator, the same, as long as it has fuel.

While batteries give 12v output, the 'time' it will last is not indefinite, therefore the 'amount' of that 12v you use is going to impact the 'time' you have to use it - and it will be different in almost any and all situations.
Even if your neighbor has your exact same coach, parked right next to you, and under the exact same conditions, will probably not have the same outcome. It's just the nature of batteries.

This reminds me of the time I helped with my city's power bills - the billing department seemed to be the front for many calls and complaints about why the bill was so 'high'.
Inevitably, the conversation went from why 'my' bill is so high, to why is my bill not the same as my 'neighbors'??
The reality is that the neighbor's house may be better insulated.
They may run the air conditioner less.
They may not leave the front door open.
etc.,....

It's the same power source, and will bill for the same amount of usage, but one house that 'looks' like another house may not necessarily have the same bill!

Why did you install the remote switch? Doesn't that inverter have an automatic transfer switch?

I believe the remote switch he installed was to power the inverter on/off and not an automatic transfer switch taking different power sources.

That was my point. If it's automatic, then why would you need to turn it off?

They are two different things. The auto transfer switch will take either the inverter AC power, or the AC power from shore/generator and out put it to the circuit. The on/off switch will turn the inverter on or off. So if you are not connected to shore power and the inverter is on, then the inverter will supply power to the circuit. If you do not want all the devices on the circuit to consumer power, for example TVs for standby, fully charged laptop, etc. then you power the inverter off, thus not inverting power for nothing.

To keep from running down your batteries when stored without shore power. Or to lessen the use of your batteries when boondocking and you don't need 120 VAC.

- an automatic transfer switch, or relay in an inverter, simply 'bypasses' the Inversion and passes thru 120v power from the original source: generator or shore power, since you don't want the Inverter 'inverting' when there is already 120v power available

- the 'on/off' switch, remotely, is simply to power down the Inverter when it's not needed, and DOESN'T need to remain on, such as when the RV is in storage, when you're plugged into shore power for weeks or months, etc.: otherwise you might have to turn it on/off from it's built-in switch/button, which is sometimes hard to get to or not easy to reach, depending on where the Inverter is mounted/stored/installed.

Most of us with larger Inverters, such as the Magnum ME2012 or MS2012, have a Magnum 'Remote' - which is a readout panel, usually above the door, or in the hallway, that no only shows battery levels, and provides for changes of settings, but also turning the unit On and Off. If I had to turn my Inverter on and off from the inverter itself, I would be very aggravated, as I would have to go outside, and reach in to a very tight space and 'hope' that I was pushing the button, since the way it's mounted in the small inverter bay.

Thanks for the replies. I'd like to add an inverter to power TVs and outlets. I was thinking of getting the AIMS 1200W inverter that was mentioned earlier in this thread. My plan is to do something like in the attached diagram. I would transfer the desired TV/outlet circuits from the existing panel to a new sub-panel, which would be powered from the inverter. And I would have AC power supplied from the existing panel to the inverter. Would this work okay?


The trick is to figure out where to install the inverter and the new sub-panel. There is a compartment under the bed next to the compartment with the exiting panel that might work if we install some cooling vents there.

Yes but it give you the option of shutting it off totally. Plus it show GREEN light when on inverter and YELLOW when on shore power. But its switches so fast the TV does not even flicker when watching them.

Plus by having this swich I can run the Frig on 120 (Genney or shore) 12v battery or Gas. So now I have a 3 way frig if I want.
