Travel Guide-WELLSEE tell you How to Choose a Power Inverter for your RV or RoadTrip Vehicle

Finding a device to convert DC power to AC may seem like it should be a simple task, but when you start shopping for a power inverter for your RV or road trip vehicle, you'll soon find that many choices will confront you. With prices ranging from less than $40 to well into the thousands, it can be difficult to know what features are important and how to choose a unit appropriate to your needs. While wattage, features, and connections are obvious considerations, your final choice should take into account the inverter's wave form output.
Types of RV Power Inverters
Not brand, but type. Just as there are types of engines (gas, diesel, etc.). There are two general types of power inverters: pure sine wave or modified sine wave (square wave).
pure sine wave inverters produce power that is either identical or sometimes slightly better to power from the public utility power grid system. The power wave when viewed through an oscilloscope is a smooth sine wave.

Modified sine wave and square wave inverters are the most common types of power inverters on the market. Modified-sine wave power inverters produce a power wave that is sufficient for most devices. The power wave is not exactly the same as electricity from the power grid. It has a wave form that appears as a choppy squared-off wave when viewed through an oscilloscope.
At first glance, these Power Inverters are not cheap. But in terms of efficiency and the doller per watt cost compared to what you get out of them, they're cheaper than the less-efficient units.
Some can be held in your palm and simply plugged into a 12VDC receptacle. Other, larger output models, require elaborate installation. Some have features and options well worth an added cost.
What RV Power Inverter Should I Buy?
It depends on what you're going to use it for. You don't buy a 20-ton truck to pull a 10-foot camper. You don't pull a large trailer with a tiny plastic car. If you only want to operate a computer or similar low-energy user, all you may need is a small (300 watt) inverter. If you're going to run a microwave or power tools, you may need a 1,200 watt or larger inverter. You may actually find it more efficient to have more than one inverter.
What Size RV Power Inverter do I Need?
Do you want to use a Microwave or mutiple appliances at the same time? You'll need over 1,200 watts capacity. You'll also need at least 200AH (Amp Hours) of battery capacity (to run a microwave for brief periods). You'll need more battery reserve for longer periods and heavier loads. If you'll be cooking full dinners for 30 minutes, you'll need a 400AH battery capacity.
COST: The cost of power inverters, in general, has gone down over the years and they are more affordable now than they have ever been. We have WELLSEE WS-P pure sine wave inverter 1000W -6000W, any requirement, please contact us, or email us. We will give you the best price.
Just want to operate a TV or computer? Usually a 200 to 300 watt inverter is enough.
When it comes to buying an RV power inverter there are two ways to go:
One. Get a good, efficient 1,200W or larger inverter and feed the whole place.The best ones are 90+% efficient and no longer need to be matched to the load.They'll do nearly as well running a small load as a big one. Incredible but true.
Two. If you don't need a big inverter, consider having one or more smaller power inverters and use the size appropriate for the job at hand.
Maybe have an 800W for everything except a microwave. Perhaps a 300W for TVs, VCRs, stereos and satellite systems. A 200W palm-size may operate a small TV, small stereo, computer or breathing machine. The breathing machine is a prime inverter use. A palm size can be easily plugged into RV or tow vehicle cigarette lighter receptacle and can bring freedom to the camp-ground bound.

RV BATTERIES: Technically, you can run anything you want from an inverter -- if it's big enough and you have enough batteries and if you have a way to keep the batteries charged. But an RV, while it may be a home, is not a homestead. Space and weight are considerations. So practically you woun't be able to run your aircoditioner on a power inverter. And you probably won't be able to run everything at once even with a large RV power inverter. Small inverters can be used on a one-battery system with hardly any difference in amp draw. Large inverters will demand two batteries or four (or more) with heavy loads.
