    Which is the better option during power cuts- generator or inverter?

    Do you want to know whether an inverter or a generator is better during a power cut? Find out whether you should buy a generator or an inverter to tackle power cut problems.

    I need an opinion on which is the better option for a one floor building ie 4 bedrooms, 2 kitchens, four bathrooms and 2 halls. Though we will not use all the rooms simultaneously, but I need to have them connected. Is generator better or inverter in my situation. What are the pros and cons? How much will they cost and what would be petrol or electricity charges?

  • I refer to Inverter better than generator . This is because . You can charge inverter when you have power in your location and another advantage is that you can setup inverter to automatic on when power down whereas a generator need to start when power down so it takes some time another disadvantage of generator is that the price of diesel increase day by day everyone know that the price of diesel never down . it may be possible to increase more high.

  • I suggesting you to buy an Invertor.
    Invertor is very user friendly and less maintenance cost. you need not to buy a Generator, because the Invertor is enough for you wholely.
    Also, there are no power cuts which exists more than 5 days. You can enjoy the power of invertor 2 to 5 days.
    Besides the argument of Noise Pollution air pollution etc., from a practicality standpoint, if your locality gets 8-10 hours cut a day with continuous cuts more than 3-4 hours, a generator makes more sense. Don't forget that diesel is very dangerous to health. You can get LPG or Diesel one to save costs. Inverter will be more expensive initially, but you will recover the cost within 2-3 years if you go for a good branded product. Su-Kam and Hyundai are good candidates. Of course a Desi inverter will cost less, but the headache is not worth it. Have already suffered. You can get easy EMI on most leading brands for 4KVA-5KVA inverters, but the cost will be very very high, initially that is.

  • Inverters are definitely better than generators for household uses. It requires less maintenance cost and runs smoothly for years. However, if you run a company than go for silent generators as they can generate more energy than inverters.

  • Yes, I do agree with Phagu Mahato, you should prefer an inverter instead of a generator. You can give connections to all rooms from the inverter and use them as per your required. There are many benefits by using an inverter instead of a generator.
    Generators run by fossil fuels, so they cause both air pollution and noise pollution but an inverter does not cause any such pollution.
    We know that the cost of petrol and diesel is increasing day by day, so using of inverter is more economically better than generators.
    We can put the inverter at any corner of our home but we need to create separate generator room to kept the generator as we cannot keep generator inside our house; because while running a generator produces poisonous gas like CO.
    You can use a 1500 VA inverter which may cost maximum Rs. 10000 and two batteries may cost you more Rs. 10000; so you have to spend approximate Rs. 20000 to connect all rooms with an inverter.

    If you think about a generator then you have to spend a lot as compare to an inverter. You cannot get a good generator lower than Rs. 20000/-.

    So it is better to prefer an inverter instead of a generator.

    Thanks and regards,

  • I think generators are meant for big apartments and offices uses where in the usage of power is more. But in your case it seems to be house hold requirement for which Inverter is the better option. The end use is limited and there are small versions of Inverters available in the market which are cost effective too.

  • The choice between inverter and generator for meeting the stand-by power requirement certainly depends on the load that is to be catered when the regular supply of electricity is interrupted. Here in the question the writer has already specified the requirement. Under these conditions the inverter is the better choice for the following reasons--
    1)The capital required for the inverter will be in the range of RS.14000/- to Rs.16000/-. The cost of the generator will be above Rs.20000/-. If, however, a battery started generator is the choice then its cost will be still higher.

    2)The inverter starts supplying power to the circuit in the house automatically as soon as the regular power supply from the mains fails and thus there is no interruption at all. In case the generator is the stand-by arrangement for power supply then one has to start it. That causes interruptions and delay occurs.

    3)The inverter can be put-up inside the house in some corner while generator needs a separate shed out side the house and at times, for its installation, a foundation is to be made. This not only adds to the capital cost of the stand-by power source but also causes lot of inconvenience to the house owner if the generator is to be started at odd hours or when weather conditions are bad like in rains or hot summers.

    3)The generator is source of both noise and air pollution. Apart from annoying and harmful noise that it makes during its operation , the smoke generated by the burning of the fossil fuel is very harmful for the health of the human beings. The inverter makes no noise what so ever.

    4)Since switching on of the power is required to be done only in that room which in use then in the situation when the inverter is the source of stand-by power the running cost of the arrangement is comparatively much less.

  • Hi

    Please note the following options for your selection.

    The functioning of the inverter is dependent on the power supply. They do not have moving parts so they are not producing noise. You can install this device inside your house and allocate a space for the device inside the house. It is suitable for houses when there are more houses nearby. It will not be suitable if you have very long power cuts frequently. As you have less time to charge the batteries. Can start in automatic mode. Maintenance is less.

    A generator is a mechanical device that converts the calorific value of a fuel into electrical energy. So it is having lot of mechanical components so it produces noise pollution. It is suitable for places where the houses are not very near and are far way from each other. It is suitable for external application only. During power cuts you have to take the generator from your house and start it. You can place the generator permanently outside if you have a safe place for it. They run on fuels such as kerosene, petrol, diesel. So storage of the fuel or maintaining the fuel level in the fuel tank is mandatory for functioning of the machine. All fuels are having fire hazard so you have to take care of the fire safety aspects also. They deliver very high energy output. Machine to be started during requirements. You have replace the spare parts after a time period. Procuring fuel frequently is a add on expense. In overall generators require every day care and will be expensive for small energy outputs. It is also available in portable model.

    Some of the brands for inverters are Emerson, Mahindra, Amara raj. Some of the brands for generators are Honda, Birla power.

  • Recurring expenditure of power bill, due to continuous charging. In case of inverter the AC supply is converted in DC , by changing sinusoidal wave form to half wave, which causes almost 15% loss in power.( in other words, you pay 15% more for the charging that the actual current used for charging ). Second point is, when you convert the AC to DC through rectifire, *( which is basically thyrister control )third harmonics are developed, hence the severe distraction of the wave form, which is not good . Third point, when you use battery power, its DC converted in AC through transformer, there is again loss of power to the tune of 15%.
    Last point is , the battery life is just 2-3 years. If you dont replace the battery, the power back up timing reduces considerably.
    Up to 2-3 KVA inverter is good, but beyond that , one should go for the generator.
