Home Inverter

What is a home inverter?

Home power inverter is to supply uninterrupted power to run family electrical gadgets.

These inverters for home are available in different voltage and load capacities.

In the fundamental design of the home inverter is a DC (battery) source is linked to a transformer that inverters the power to AC 230V


Range: 1000VA ~ 2000VA (1:1 Phase)

How big of an inverter do I need to run my house?

Calculate approximate start-up load (peak/surge watts).

You would need an inverter with a continuous rating of roughly 1500 watts and with a peak/surge rating of approximately 3500 watts.

It is constantly recommended to build in a safety factor by overrating the continuous score by 20– 25%.

Is it safe to keep inverter inside the house?

Yes, with appropriate ventilation (proper for the size of the system), it is safe.

A small system, say 100w of inverter and solar panels, would be safe without extra ventilation for the most part.

However, a much bigger system needs much higher care.

Does inverter increase electricity bill?

However, when the inverter goes on charging its batteries, it will take in sufficient power and for this reason will get reflected in your costs. So on the whole your bill will be more compared to the case without inverter.

The costs will begin to increase as batteries begin to age.

    These inverters for home are available in different voltage and load capacities. In the fundamental style of the home inverter a DC (battery) source is linked to a transformer through the center tap of the primary winding.

    A switch is rapidly switched backward and forward to allow existing to flow back to the battery following 2 alternate courses through one end of the primary winding and after that the other.

    Types of Power Inverters

    Based on the output waveforms, there are 3 types of Inverters. These are Sine wave, Modified Sine wave and Square wave inverters.

    Sine wave power inverter

    Sine Wave Power InverterAlternating current has continuously differing voltage, which swings from positive to negative.

    This has a benefit in power transmission over long distance.

    Power from the Grid is thoroughly managed to get a pure sine wave and likewise the sine wave radiate the least quantity of radio power throughout cross country transmission.

    However it is costly to generate sine wave in an inverter. Its quality is outstanding and almost all electrical and electronic appliances work well in sine wave inverter.

    The sine wave is the AC waveform we obtain from the domestic lines and from the generator.

    The major benefit of sine wave inverter is that all of the house hold appliances are created to run in sine wave AC.

    Another advantage is that the sine wave is a type of soft temporal increase voltage and it lacks harmonic oscillations which can trigger unwanted counter forces on engines, interference on radio devices and surge current on condensers.

    Modified Sine wave or Quasi Sine wave

    Modified sine wave is designed to simulate a sine wave given that the generation of sine wave is expensive.

    This waveform consists of a Flat Plateau of positive voltage, dropping quickly to no for a short period, then dropping once again to a flat plateau of negative voltage.

    It then go back to no once again and returning to positive. This short pause at no volts offers more power to 50 Hz basic frequency of AC than the simple square wave.

    Inverters providing modified sine wave can adequately power most house hold appliances.

    It is more economical but may present certain issues with appliances like microwave ovens, laser printers, digital clocks and some music systems. 99% of appliances run happily in modified sine wave.

    Instruments utilizing SCR (Silicon Controlled Rectifier) in the power supply area behave terribly with modified sine wave.

    The SCR will think about the sharp corners of the sine wave as trashes and shut off the instrument.

    A number of the Laser printers behave like this and fail to work in inverters and UPS providing modified sine wave power.

    The majority of variable speed fans buzz when utilized in modified sine wave inverters.


    Power Rating of Inverter

    Inverters are readily available in various ‘Size rankings’ from 50 VA up to 50000 VA. Inverters larger than 11000 VA are rarely used in household applications.

    The first thing you have to consider about the inverter system is its optimum peak power or surge power and steady existing supply. The surge score is usually specified at a lot of watts for a lot of seconds.

    This implies that the inverter will manage an over load of that numerous watts for a short time.

    This ‘surge capacity’ will differ considerably between inverters and even with in the very same brand.

    Generally 3-15 seconds surge ranking suffices to cover 99% of appliances. Inverters with lowest surge rating are the high speed electronic changing types.

    Selecting the Best Home Power Inverter

    Prior to selecting the inverter, it important to calculate the overall power consumption of the appliances that are going to be linked to the inverter.

    It is important to keep in mind that the power usage (Current drain) increases when the driving voltage decreases.

    When the input voltage drops in the domestic supply lines from 230 V AC to 200 VAC, electric gadgets will take in more current. For example a load ranked 300 Watts (like Fridge) operating in 230 volts uses 1.4 Amps in one hour.

    The very same load takes 1.5 Amps if the line voltage drops to 200 volt during peak hours (6pm- 9 pm). So it is suggested to switch off high present devices during peak hours.

    This conserves energy as well as reduces the electrical energy bill.

    If heavy loads are running in inverter, battery voltage reduces from 13.5 volts to 12 volts with in a short time.

    This lowers the backup time. So it is better to link only light loads such as fan, lights and TV to inverter lines.
