Power cuts can disrupt your daily life, especially in areas where electricity isn’t always reliable. That’s why having a backup generator is not just a luxury—it’s a necessity for many homeowners in India. If you’re moving into a new home, choosing the right generator is a critical decision that impacts your comfort, safety, and budget.
In this guide, we’ll walk you through the key factors to consider while selecting the right home generator, so you can make a confident and cost-effective choice.
1. Understand Your Power Needs
Before purchasing a generator, you need to determine how much power your household appliances and systems require during an outage.
Make a list of all essential devices you want to run on generator such as fans, lights, refrigerator, water pump, and possibly an air conditioner. Add up their wattage and choose a generator that can comfortably handle that load.
Pro Insight: For a typical 2-3 BHK Indian home, a 3.5 kva to 5 kva generator is usually sufficient for basic household needs.
2. Know the Different Types of Generators
There are primarily two types of home generators:
Portable Generators: Ideal for short-term, temporary use. They are budget-friendly and can be moved around easily.
Standby (Fixed) Generators: These are installed permanently and turn on automatically when power fails. They’re more expensive but offer peace of mind.
Choose portable for small homes or rental properties, and standby generators for large homes or when consistent backup is needed.
3. Consider the Fuel Type
Home generators commonly run on:
Petrol: Affordable but less efficient and noisier.
Diesel: Longer life, better fuel efficiency—commonly used in India.
LPG/Natural Gas: Cleaner and quieter, but may require setup and permissions.
If you are unsure, then just remember that the diesel generators are most popular for Indian homes due to availability and durability.
4. Set a Realistic Budget
Generator prices vary significantly based on capacity, type, and brand. A portable generator may cost between Rs 20,000 to 40,000, while a standby unit can go above Rs 1 lakh with installation.
Also, make sure to include installation, maintenance, and fuel costs in your budget, not just the purchase price.
5. Check for Installation and Space Requirements
Space and ventilation are important. Generators must be installed in a well-ventilated, covered area outside your home.
Pro Tip: If you’re moving into an apartment or society flat, confirm the society’s rules for generator installation before purchase.
6. Look for Key Features and Warranty
Look for features like:
Automatic voltage regulation (AVR)
Auto start function
Noise level rating
Overload protection
Also, ensure the generator comes with at least 2–3 years of warranty and reliable after-sales service in your city.
7. Consider Maintenance and Service Support
Generators require periodic maintenance like oil changes, filter replacements, and general servicing to stay in good working condition. Choosing a reliable brand with easy access to authorised service centres can save you a lot of hassle down the road.
Check for:
Availability of spare parts
Local service centres or doorstep support
Warranty terms and post-sales service
8. Popular Generator Brands in India to Consider
When choosing a generator, picking the right brand matters as much as the power specs. Some brands are known for durability, service support, and long-term performance.
Here are some top generator brands trusted by Indian homeowners:
Honda – Known for fuel efficiency and quiet operation
Greaves – Offers reliable diesel and gas generator options
Mahindra Powerol – Great for both home and commercial use
KOEL Green – Popular for eco-friendly and silent generators
Elemax – Ideal for portable backup needs with stable output
Each brand has different models catering to specific budgets and needs. So, compare the warranty, fuel type, and key features of the generators before making a final call to buy one for your home.
Buying the right generator for your new home isn’t just about picking the biggest one you can afford. It’s about understanding your needs, being mindful of your budget, and making a smart choice that offers long-term reliability.
