Powercuts in India are quite common. According to the 2019 Global Competitiveness Index by the World Economic Forum, India ranked 108 out of 141 countries in electricity supply quality. This shows how much urban power outages have been happening for quite some time.
Frequent power outages, voltage drops, and fluctuations can hurt appliances, lower productivity, raise production costs, and lower standards of living, which is why a lot of people would rather invest in backup power solutions, like an inverter and an inverter battery.
Randomly picking an inverter and battery combo and calling it a day is not the right approach. Here at Livfast, we are committed to providing you with the best performance, and it comes with transparency. Which is why in this article, we’ll be telling you how to select an inverter and battery for home.
Understanding Your Home Power Needs
The inverter and battery buying guide for home starts with you calculating how much power your home needs.
Step | Description | Formula | Example |
1 | List appliances & note wattage | Check device label/manual (W) | TV = 100W |
2 | Calculate daily watt-hours (Wh) | Wattage × Hours used per day | 100W × 4h = 400 Wh |
3 | Convert Wh to kWh | Wh ÷ 1000 | 400 ÷ 1000 = 0.4 kWh |
4 | Calculate monthly usage | Daily kWh × 30 | 0.4 × 30 = 12 kWh |
5 | Find total monthly consumption | Sum of all appliances’ kWh | Depends on the household |
6 | Calculate monthly cost (optional) | Total kWh × Tariff (₹/kWh) | 12 × ₹X = ₹X |
However, if you’re busy and feel like this is quite time-consuming, you can simply list down your appliance wattages and use any online calculator to calculate the load. Most of them are accurate, and you’ll get your starting point. Here’s a sample load calculation for your reference:
Appliance | Wattage per Unit (W) | Quantity | Total Load (W) |
LED Bulb | 10 W | 6 | 60 W |
Ceiling Fan | 60 W | 2 | 120 W |
Tube Light | 18 W | 3 | 54 W |
Television | 80 W | 1 | 80 W |
Refrigerator | 200 W | 1 | 200 W |
Total Connected Load | Â | Â | 514 W |
Recommended Load (with 25% Safety Margin) | Â | Â | 643 W |
Choosing the Right Battery Type
Now, you need to pick the right battery type. There are two types of batteries: Lead-acid batteries and Lithium-ion batteries.
Lead-acid batteries like the one used in MXST 1648 are cost effective-reliable and easily work well with deep discharge cycles. Their pros include:
- Low cost
- Good for heavy loads
- Proven Technology
While its cons include:
- longer charging time
- periodic maintenance required
- shorter lifespan
On the other hand, Lithium-ion batteries are also popular. They have a higher upfront cost but are relatively low maintenance, and options like Livfast Lithium Alpha DT 100Ah come with features:
- Faster charging (2× lead-acid speed)
- Longer lifespan (6 times longer than conventional batteries)
- Low maintenance / zero water topping
- Backup example: 3+ hours at 400W
- IP55 rating – ideal for humid areasÂ
- App-based monitoring for state-of-charge, health, and backup time.
Picking the type of battery depends on your needs and wants, but the baseline is that the battery you pick should match the Load.
Selecting the Right Inverter
Now, here’s a table that would make the choice of how to select inverter and battery quite simpler for you:
Criteria | Small Home | Medium Home |
Inverter Capacity | 900 VA | Higher VA options |
Power Output (Watts) | 765 W | Suitable for medium loads |
Charging Current | Standard charging | Up to 22A fast charging |
Ideal Load Range | ≤ 650–750 W | 800–1500 W |
Waveform Type | Pure Sine Wave | Pure Sine Wave |
Suitable Appliances | Fans, lights, TV, refrigerator | Multiple fans, lights, TV, fridge, and additional devices |
UPS Mode | Yes (instant switchover) | Yes |
Overload Protection | Yes | Yes |
Deep Discharge Protection | Yes | Yes |
Solar Compatibility | Optional | Available (model dependent) |
Display Type | LCD | LCD with advanced indicators |
Charging Technology | Smart / AI-based charging | AI fast charging |

Recommended Livfast Inverter & Battery Combos
If you feel like you just want an easy solution, here’s a Inverter and battery combo that suits both small and medium homes.
Home Type | Inverter | Battery | Backup* | Warranty | Best For |
Small Home (≤800W) | Vision HDX 1100i (900VA) | Lithium Alpha DT 100Ah | 3+ hrs | 3 yrs | Fans, lights, TV, fridge |
Medium Home (800–1500W) | SmartFlash / Flashcharge | Tubular 150–200Ah | 4–5 hrs | Up to 3 yrs | Larger homes, pumps, washer |
*Backup at ~400W load.
Conclusion
To put it simply, you need to make sure that your needs match the inverter’s capacity. It should be able to meet or slightly exceed your daily power needs. If you go too small, you could overload. On the other hand, getting too big can be a waste of time and money. Also, think about surge power without tripping. Finally, see if ratings meet your needs now and in the future.
