The Essential Guide to Selecting the Right Home Inverter and Battery Capacity – Powered by Electrent
Share
In today's world, consistent and clean energy is a necessity. With rising power demands and unpredictable outages, a reliable home inverter is no longer just a luxury but a crucial element in every household. Electrent, one of India’s fastest-growing cleantech startups, is leading the charge in transforming how homes access backup power. If you’re wondering how to select an inverter for home, this guide will help you navigate vital concepts such as inverter capacity, battery sizing, and how to choose the right solution for your home’s specific requirements.
Inverter Purchase Guide: Understanding Your Requirements
Before purchasing any home inverter, assess your power needs. Start by identifying which appliances you want to use during a power cut—commonly lights, fans, a TV, refrigerator, or computer. Each device has a wattage rating, typically mentioned on the product label.
Step-by-Step: How to Select Inverter for Home
1. Write down all appliances you want to run simultaneously during outages.
2. Sum their wattage ratings.
3. Account for the power factor (commonly 0.7) to convert watts to volt-ampere (VA), which is how inverter sizes are specified:

4. For example:
If your total would be 400 Watts (e.g., 3 fans + 4 lights + TV):

Electrent recommends always rounding up, so a Pure Sine Wave UPS 850/12V would be suitable for this load.
Choosing the Inverter Capacity for Home

Inverter capacity is fundamental for uninterrupted operation. For small homes or limited backup, Electrent’s Pure Sine Wave UPS 700/12V or 850/12V offer a compact solution. Larger households, especially those including heavy appliances like refrigerators or ACs, should consider higher capacities such as the UPS 3500/24V or UPS 5500/96V line, ensuring smooth operation for all critical appliances.

Inverter Battery Capacity – Maximizing Backup Time
Battery capacity (measured in ampere-hours, Ah) translates directly to backup time. Choosing the right capacity is vital to ensure you get enough hours of power before recharging is needed.
Calculating Home Inverter Battery Capacity
The formula to estimate the battery capacity you need is:

For example, with a 400W load, 3 hours backup, 12V battery, and 0.8 efficiency:

Electrent offers pure sine wave inverters that efficiently utilize every bit of battery power, meaning longer backup times and more reliability for your home.
How Much Ah Battery Required for Home?
For basic uses (lights, fans, TV), a 100–150Ah battery suffices for most homes wanting 3–4 hours of backup. Larger setups or longer run-times (more appliances, ACs) may need 180–220Ah batteries. Opting for Electrent's lithium options means even greater efficiency and faster charging, ensuring you’re covered for every scenario.
Matching Inverter Size and Wattage to Your Home
Choosing both the right inverter wattage and battery Ah is crucial. If you choose an inverter that’s too large for your needs, you’ll spend more unnecessarily; too small, and you risk frequent overload shutdowns.
· Small homes: 700VA–1500VA, 100–150Ah battery (Pure Sine Wave UPS 700/12V, 850/12V, 1350/12V)
· Medium/large homes: 1800VA–5500VA, 150–220Ah battery (UPS 1800/24V to UPS 5500/96V)
· Heavy appliance use: Consider ELECT+ Pure Sine Wave UPS 10000/120V, paired with appropriately sized lithium batteries for extended, maintenance-free backup.
