How to select Inverter for home use with some example

Selecting the right home inverter in India is crucial to ensure uninterrupted power supply during frequent power cuts and outages.

By following these steps and considering your specific requirements, you can select the correct home inverter for your needs in India.

Determine Your Power Requirements:

  • List all the appliances and devices you want to power with the inverter.
  • Note down their power ratings in watts (W) or kilowatts (kW). You can find this information on the product labels or in the user manuals.

Calculate your total power load:

  • Add up the power ratings of all the appliances you want to run simultaneously. This will give you the total power load you need the inverter to support. Consider both continuous and peak loads (if applicable).

Example: Suppose you want to back up for the following appliances during a power outage:

  • Refrigerator: 800W
  • Lights: 200W
  • Television: 150W
  • Laptop: 50W

Your total power load is 800W + 200W + 150W + 50W = 1200W (or 1.2kW).

Budget:

Set a budget based on your requirements and stick to it. Inverters are available in a wide price range, so you can find one that fits your budget.

Choose the inverter type:

There are two main types of inverters for home use:

  • Pure sine wave and modified sine wave. Pure sine wave inverters are generally more expensive but provide a clean and stable power supply, suitable for all types of appliances.
  • Modified sine wave inverters are more affordable but may not be suitable for sensitive electronics.

You want your inverter to run these appliances for 4 hours during a power outage. The battery voltage of your inverter is 12V.

Using the formula for battery capacity (Ah): Ah = (1200W x 4 hours) / 12V = 400Ah

Considering a margin of safety, you might choose a 500Ah 12V battery or two 250Ah 12V batteries connected in parallel.

Select the Battery Type:

  • There are two main types of batteries for inverters: lead-acid batteries and lithium-ion batteries.
  • Lead-acid batteries are more affordable but require regular maintenance, including topping up with distilled water.
  • Lithium-ion batteries are maintenance-free and have a longer lifespan, but they are more expensive.
  • Choose the battery type that aligns with your budget and maintenance preferences.

Inverter Features:

  • Consider additional features such as digital displays, battery status indicators, and overload protection.
  • Some inverters come with features like automatic voltage regulation (AVR) to stabilize voltage fluctuations.

Brand and Warranty:

  • Choose a reliable and reputable brand that offers good after-sales service and support.
  • Check the warranty offered by the manufacturer for both the inverter and the battery. Longer warranties are often indicative of better quality.

Installation and Maintenance:

  • Ensure that you have a suitable place for installing the inverter and battery. It should be well-ventilated and away from direct sunlight and moisture.
  • Check if the inverter requires professional installation, and consider maintenance requirements.

Read Reviews and Seek Recommendations:

Read customer reviews and seek recommendations from friends or family who have experience with the specific inverter model you’re considering.

Example: Suppose you want to power the following appliances during a power outage:

  • Refrigerator: 800W
  • Lights: 200W
  • Television: 150W
  • Laptop: 50W

Your total power load is 800W + 200W + 150W + 50W = 1200W (or 1.2kW).

You want your inverter to run these appliances for 4 hours during a power outage. The battery voltage of your inverter is 12V.

Using the formula for battery capacity (Ah): Ah = (1200W x 4 hours) / 12V = 400Ah

Considering a margin of safety, you might choose a 500Ah 12V battery or two 250Ah 12V batteries connected in parallel.
