It is good to have a backup power source at home as this will help you when there are frequent power cuts in your locality. The inverter is designed for this purpose and can provide backup power for 4-12 hours. Thus it can save you from a lot of trouble occurring because of load shedding. In this article, we will review some of the best inverters which you can consider for buying.

Parameters to Consider Before Purchasing an Inverter
- The load that an inverter needs to bear is the most important factor to be considered before deciding which is suitable for your home. If you need to run just the basic fans and lights, the Square wave inverters are best and available at a cheaper price also. But if you want to run heavy-duty loads such as microwave, air coolers, TV, and mixer grinders, you will need inverters belonging to Pure Sine Wave and modified sine wave category, which are generally expensive.
2. The number of devices that you can connect with the inverter:
- It is the inverter’s capacity measured in Volt-Amp(VA) that indicates the duration and the number of devices it can power up simultaneously.
3. Size of Battery:
- If the battery capacity is more, the backup will be more as it can store more power.

Inverter Buying Guide in India – How to Choose The Right Inverter for Your Home?
An inverter is meant for converting the direct current to alternating current and is quite useful during outages. Here are some of the specifications that you need to look into for getting the best inverter for your use at home or office:
1. VA Rating:
Various daily use appliances have different electricity consumption. And in the case of outages people prefer bare minimum requirements to be fulfilled so they connect only essential devices to the inverter to avoid interruption because of power cuts. Based on the number of hours you need backup, the connected appliances have to be used.
VA is calculated by dividing the total needed load (watts) by 0.8. It is the maximum load that your inverter should take. Now, while buying, make sure to opt for a VA more than this for safety. Though this can be expensive, you will find it useful in the long run.
In case you want to run the refrigerator and AC with your inverter, the ideal inverter would be the one with high capacity and a small battery.
2. Check the Inverter Type:
i. Sine Wave Inverter: Most appliances are compatible with this type which has a rotating AC machine for power generation. They are costly but have the potential to carry heavy loads.
ii. Modified Sine Wave Inverter: Its waveform is like a square and is compatible with most appliances. Its drawback is that the device’s efficiency decreases and you can hear some noise. They are less expensive with respect to the above type.
iii. Square Wave Type: It has the least price among the three types but still unpopular because of the inefficiency and incompatibility with various appliances.
3. Battery Type:
The internal technology for storing current determines the type of battery used in an inverter.
i. Flat Plate:
They are lead-acid batteries of first-generation. It has sulphuric acid and water as the electrolyte solution in which the two electrodes are immersed.
These lightweight batteries are priced between ₹ 9000 to ₹ 15000. The distilled water has to be filled up every 3-6 months based on your use. In case you do not do this regularly, the battery life will be reduced. Since they emit toxic gases, it is recommended to avoid placing them in closed rooms. Currently, they are outdated models.
ii. Tubular Model:
These batteries have deep charging cycles and last long generally for 5 years. They are the most popular and available at a price range of Rs. 9000-25000.
iii. Value Regulated Lead Acid:
They are sealed and maintenance-free so you do not have to frequently refill the distilled water. They are more expensive compared to the other two models but shorter life.
4. Inverter Vs. UPS:
100 milliseconds are needed for switching during an outage whereas UPS takes just 3-5 mile sections. Hence UPS is needed in case of devices like PCs that require no power interruption during operation. UPS is again of two types- the online UPS which supplies power even while the mainline is on and the offline UPS which works only during an outage.
Inverter Safety Measures
Here are some basic safety measures which you must be aware of before starting the use of an inverter:
Make sure that your house wiring is suitable to install the inverter and connect various appliances to it. If not, get an electrician to do this before buying one. You can avoid connecting certain appliances to it if you want, based on your need.
Also, check if your house has proper earthing to prevent short circuits and electrocution.
2. Battery and Inverter Capacity:
When your power requirement is more, opt for an inverter and battery with larger capacity:
- 750 VA inverter needs 50 Ah battery(300-watt power requirement)
- 1550 VA inverter needs 100 Ah battery(600-watt power requirement)
- 3500 VA inverter needs 300 Ah battery(900-watt power requirement)
- 4000 VA inverter needs 300 Ah battery(1000 watt power requirement)
- 6000 VA inverter needs 400 Ah battery(1200 watt power requirement)
This is needed to safely position the inverter in the ground level. Try to place it close to the mains supply to avoid unnecessary clutter because of wiring.
4. Safety of Kids and Maintenance of Inverter:
Make sure no kids go near the device and also avoid touching the device with wet hands.
Don’t forget to refill water in the battery to make sure it functions well.
Go for brands that offer a good warranty because this ensures that the device will last long.
You must be well versed with various parameters of an inverter before buying one. Besides this sticking to the safety precautions can ensure a better experience.
Frequently Asked Questions (FAQs)
Ans: No. You should keep it in a well-ventilated room to avoid inhaling the toxic fumes from the inverter.
Ans: No, because this will discharge the battery and it won’t be able to provide backup in case of a sudden outage. It can be turned off only while refilling the distilled water. But make sure to turn it on again.
Ans: It is an inverter that converts PV panels DC output into AC for providing backup. A solar converter has to be added to the inverter for this. Models available for domestic purposes generally don’t have this option.
