Inverter

What are you going to invert?

That is to ask, do you have the remaining components of the system?

If yes, please list them.

If no, what are you going to invert?

I dont have any component or system and have no idea how it`s works .But will like to have one ,there is erratic power supply in my country .

Have you tried multiplying (or dividing) by -1?

Power inverter - Wikipedia, the free encyclopediaI

inverters and converters, manufacturers: Germany

Thanx alot for your contribution ,u will hear from me soon

You didn't tell him whose rate button to click on.

not your's for sure

What you need is a back-up generator system, this would be the cheapest way to go for most circumstances...

And AVR plus Surge Suppresor.

is a possibility.....they have cheap stuff good quality as does:-

Pearl Agency

If you can read German that is......also:-

German-inverter

Which is in both languages if I remember correctly....

Do you have a take on how much power at what voltage/frequency you need?

Also, I am surprised that you need the continental type socket that Germany uses, I thought where you lived, the British 3 pin was almost standard.......obviously a converter can be bought to change from any plug/socket type to any other, but do watch the earth pin, that is sadly not always converted correctly....

Best of luck.

Google 'Tamera solar testfield' in Portugal for ideas on power development. Idea's for inverter use can be found at 'instructables.com'

The inverter you refer to is a "black box" that takes electricity from some thing like a car battery and makes it the same as your household electricity. The important thing for you to know is that it is the SAME as your household electricity, in that it is DEADLY. For your application, size is important. You cannot power your fridge and TV from your car battery for example. This why other posters have asked for more details. Does your electricity bill show a usage in KW/H? That is a good starting point.Jim

You need to collect more information regarding load on the inverter. Such as lights, fans, air conditioners etc. How many watts is required to be powered. Better contact local shop to guide you.

You need to purchase inverter depending on the load in your house and the time period the power shutdown remains off ( the number of hours you need emergency alternate power and will decide the AH of the battery to be used ) . The inverter can be with auto change over switching or Manual change over switch . The inverter use battery to provide the reserve DC power which is charged when the line supply is available and the same is inverted to AC and stepped up to the required supply level and used when the power is not available in the mains. I do not know weather it is available in German market .Various makes of Inverters are available in Indian market with in built batteries or with out Batteries in which case you can purchase Batteries locally and connect to the inverter unit . Inverters are widely used in India due to the Power shortage and Load shedding in India This you can get it exported to Ghana

Thank you very much ,you are one of the few who have explain the use of inverter to my understanding . My next problem is to find a company here in Germany or can you please send me any website address in India .

M/S India mart .com will provide the address and telephone numbers of various Insdian Inverter and UPS manufacturers

Hi JIMRAT ,

You are right what PO wants is a UPS . Inverter is only a part of the item that he wants though his requirement is alternative power supply during power failure. For Engineers it is complete UPS combination of Battery /(solar power)+Charger+ auto change over / Manual Change over +Inverter + Protection .For the Electrical Market in India when we say we want Inverter they understand it as UPS less Battery .When it is a combination unit they market it as UPS .So the layman shop for inverter and he get the right thing and they buy suitable battery available locally and an electrician connect the unit for the user . In India most of the Villages and small cities and Town face power shortage and most of the houses and shops install these so called inverters + Battery to overcome load shedding and power shutdowns and power outage due to breakdowns on Distribution systems .

Mr V.I Abraham , so far you understand my situation well than the others ,I appreciate it so much please keep it up .

I also understand your situation very well. In your area an "inverter" refers to a device that is correctly known as a UPS. See V.I. Abraham's post. he also says this. You said you wanted good German inverter. If you shop for a good German inverter you will NOT get what you want. WHY NOT? Because the Germans and the English and the Americans and the Australians and the Europeans and the Indians and the Chinese and the Taiwanese all call your "inverter" a UPS. If you ask for an inverter you will just get a small part of the device you want. You will get a real inverter not what YOU call an inverter. V.I. Abraham explains that in some parts of the world ( yours ) the word "inverter" refers to a UPS. Please understand this.
Once you buy your UPS, without batteries ( to save shipping weight ) you will need to get the correct TYPE of battery for your needs. You also don't have to charge the batteries from the mains. See RedFred's posts for an explanation of why you shouldn't do this.Jim

You may be right, but using the word inverter for a complete UPS is seriously wrong.....its only a small part of a UPS.....

You may be right, but using the word inverter for a complete UPS is seriously wrong.....its only a small part of a UPS.....That is exactly what i am trying to tell him. In a few posts now! When I.V. Abraham said that in his part of India they call a UPS "inverter" the confusion in OP's mind became clear. I have tried to tell him .... well, you know the rest.
Jim

Lets hope he reads your comments and if he doesn't understand, that he simply asks.

I personally feel that the OP simply hasn't clue.....

The critical thing you have not included is where the energy in the batteries comes from. If these batteries are non-rechargeable batteries like a common alkaline cell then they must be frequently replaced. If these batteries are rechargeable batteries they will eventually have to be replaced but more importantly they will draw even more power from a marginal power grid than they return when the grid is OFF line. This can induce less ON line power grid time. [Particularly when many people have batteries to be charged.]

IMHO a real alternate source of power will be much better than double dipping from an unrelieble source of power.

Good point RF.

Hi redfred

It is clear that the Battery has to get charged from the regular power supply with float charging arrangement ( This combination is commercially known here as inverter). The life of the Battery is good when maintained properly and " inverter unit " comprising of charger ,change over switching during power failure and protective circuits when kept ON continuously ,serve as alternative supply during power failure. Unlike in US in India the power outing in Villages , Towns and Small cities are often due to acute shortage of electricity production specially in summer . So most of the houses and shop install UPS unit commercially known here as Inverters and Battery purchased separately . When it is purchased as a combination it is termed as UPS units ( mostly for computers and electronic equipments ).

You are missing my point.

It is clear that these batteries must be charged from a power source prior to use but this power source does not have to be the already overworked, inconsistent central electric power system. Adding an additional power source to an inverter based system can make this a more self sufficient system and lessen the burden on the inconsistent central power. What type of alternate power supply will depend on the available power. This is an additional option that should be considered on a case by case basis.
