Hi gelp my plz i wnat to get an inverter that will power my house to save electricity bills which watt to buy?
finally wat wattage shall i buy to power my house e.g 6000w 7000w 8000 etc
finally can u plz name one on ebay .co.uk that u would recomend for me thank you and would be most appresiated
Answer:
I think you may be confused as to what an inverter actually is.
An inverter doesn't actually generate any power, it only *converts* it from direct current (DC) to alternating current (AC.)
Household electricity is AC.
One reason you might need an inverter is if you were using solar panels on your roof. Solar panels only produce DC, so you'd need to convert it into AC before you ran it through your wall outlets.
Inverters are usually only about 80% - 90% efficient, meaning that they take in slightly more DC power that they produce as AC. The excess power is given off as waste heat.
If you want to actually *generate* your own power, you need either solar panels, a wind turbine, or some type of "co-generation" unit, like a small gas or diesel backup generator.
All of these options tend to be rather expensive, and line current is generally cheaper. However, in the case of solar or wind power, many states offer incentive programs for people with such systems. Also, it's harder to put an exact price tag on the satisfaction you get, by knowing you are generating your own, seemingly "free" electricity, watching your power bill shrink to a fraction of what it was, and knowing that you aren't spewing tons of waste CO2 into the air.
Hope that makes sense,

An inverter converts alternating current (AC) to direct current (DC) power or the other direction.
It sounds more like you are looking for a generator (actually, more like a perpetual motion machine!)
Any generator will require a fuel source, which includes solar, wind or water, if you have any of those available. In most if not all cases, the cost to generate power on your own will be higher than buying it from the electric company!
In some cases you may be able to get incentives or tax breaks from the local utility or other governmental agencies to assist with installing renewable energy generation to reduce the upfront cost.
Sizing depends on the load of your house. Add up the load of all your appliances and add 10 to 20% of the amount you intend to run at the same time. More if you plan on adding any electrical equipment in the future.
You may find it more cost effective to do everything you can to minimize your electrical load first, to reduce the required size of the generator. You may find that alone will reduce your electrical bill enough to make you happy!
You have described a perpetual motion machine. An inverter can't power your house and itself too.
