- CstolikerExplorerI saw a few. It looks like instead of switching you run on inverter all the time weather on battery or converter. Don't know how your supposed to run the AC like that.
Others have only 10amp chargers.
Decent ones are almost $1,000.00
I guess adding a 3rd party inverter is the way to go. I'll just do the same I did on the last one.
Thanks all. - wa8yxmExplorer IIILook in a mirror.. (Reverse converter and inverter)
There are dozens of IN-Line inverter/converters out there (called Inverter/charger) nearly all the bigger inverters work this way,, Most anythin in the 1500 watt plus range.. Mine is a Xantrex Prosine 2.0 (no longer made) but there are many many many others. - VeebyesExplorer IIThe converter chargers that most RVs are supplied with are miserable little things. Like a few other responders I have a pure sine wave Magnum 2kw inverter charger.
All 12V needs will be taken from the battery bank. The 3 stage inverter charger recharges the battery bank as needed. There are various ways to supply the 110VAC side to the 'house'. I wired mine to the main panel which supplys everything.
The down side of that arrangement is that somebody has to remember to leave the water heater & fridge on propane when drycamping otherwise the battery bank will be dead in no time. - Ed_GeeExplorer IIHere's another good unit common in some new RVs:
http://www.tripplite.com/rv-power-inverter-charger-750w-automatic-transfer-switching-hardwire~RV750ULHW/ - RoyBExplorer IIThere are a few of these unit out there. They are expensive however..
This is a block diagram of the Magnum ME2012-20B 2000W 12V Inverter 100A DC Charger
The way this works is when connected to shore power or Generator the MAGNUM ME2012-20B passes the 120VAC to your EMERGENCY 120VAC SUB=PANEL and also charges your connected battery bank.
When the SHORE POWER or Generator is off line then the MAGUNM ME-2012-20B auto switches and has a built-in SINE WAVE INVERTER to feed your EMERGENCY 120VAC POWER SUB-PANEL using your connected large 12VDC BATTERY BANK as power source.
Is this what you are looking for...
GOTO the MAGNUM site and read up on their different product models on this.
hope this helps some - I don't have one of these setups but have looked into them. When things cost in the thousands of dollars I usually quit my pipe dreaming.
You can do the same thing here with individual items - The MAGNUM is nice having all of that built-in a single box with a nice monitor panel.
Roy ken - As said it is an inverter/charger and will work exactly as described. Many RVs come OEM with inverter/charger set up. However they tend to be larger in the range of 2000+ watts inverter and 80+ amps charging and need four+ batteries to operate properly.
But honestly I prefer separate components and recommend a small separate inverter and separate transfer switch. Easy to wire in to the existing outlets if you have done any home wiring before.
GoPower 300w sine wave $171
15a transfer switch $50 - IvylogExplorer IIIEven if you could find a 600-800W inverter/charger, it will not have enough 12V charging amps for what you want to do. Buy a small pure sine wave inverter and put it on a A-B switch for the outlet you want to power when off shore/generator power.
- pianotunaNomad IIIHi,
Add up the wattage of all the devices that will be on at the same time. Purchase an inverter/charger that is 125% of that number for continuous demand.
I prefer stand alone converters and inverters rather than inverter/chargers. If you must go the inverter/charger route try to make sure the charger part is not over 125 amps. That way it will still run on 15 amp shore power.
Here is a place to look--and the owner is an RV'er.

I only run TV, laptops exc...but like the covenance of having the inverter power supplyed though existing outlets. 600 would be more then enough.
Thanks Chris. The name of the device is what I needed. - DennisVRExplorerI have the Xantrex Freedom 1800 which is a 1800 watt inverter/40 amp charger and automatic switch for the last 4 years and has been doing great.
