yes as Nash said it converts 12 volts to 120 volts ,, that way u can operate certain stuff while driving or boondocking ,, also if u have a big enough inverter u can run u'r a/c ,, hope this answered u'r question....
But on the down side,, the inverter is only as good as u'r house batteries are ,, in other words if the batteries are weak,, then so will the power from the inverter be ,, weak that is
I was playing with it last nite(the inverter) and was unable to get anything that plugs in to operate. Is there a way to test it? Is there a limitation on the type or size of inverter if i need to replace mine? I am in an 85 holiday rambler Imperial 33. As things wear out or brake I am trying to upgrade to newer and/or better. So far very little has wore out or broken, but i am new to this rv and not sure how all of the bells and whistles work.
Sometimes the inverter is wired to only a few outlets and/or a few built in devices. Check the manual or wiring diagram to ensure that where you are plugging in is powered by the inverter. Also, check all the breakers and fuses.
The primary limitation is your battery bank. If you don't have a lot of battery power, having a bigger inverter is a waste of effort. The next 'limitation' is what you want to power by inverter. Add up the power 'needed' and round up. If the inverter was installed at the factory, then you probably want to stay with the same size, unless you really know what you are doing (if the wiring and fusing is based on one size, just replacing it with a bigger one could cause problems).
Finally, there is the 'type' of inverter. The cheapest ones put out a square wave, triangular wave or 'modified sine wave' which are very 'dirty' electrically ('noisy'). This can cause some devices to work 'funny' or even damage some devices. The best inverters are the 'true sine wave' which provide power as good or better than comes out of the wall. Unfortunately, these tend to be rather more expensive.
Also, the bigger inverters often have battery chargers built in. You will need to make sure the new one matches the old one in this regard, or modify the wiring to compensate so the battery charging continues to work.
Texas Clodhopper, The switch that I was trying to figure out is like a light switch with 3 positions. The top position says inverter, middle position is blank and bottom says shore power. There is also a separate panel with a power button ad a reset button, but there are no indicator lights to acknowledge that the power is on or not.
Hertig, I think I will just replace it(if its not working properly) with a stock equivalent. I don't want to get into the "never ending project"
Time to pull out the VOM (volt, ohm meter) and start checking. Did you try one of the tvs while not hook to shore power? As John said ,if it's a small inverter might just be wired to one wall plug, probably in kitchen area.
