Home battery systems for India
Choose a modular LFP home battery system for essential backup, stronger rooftop solar use, or extended resilience.
Leaf 10
Family homes and home offices
Balanced capacity for confident evening backup, greater solar self-consumption, and a connected household.
Final output, compatibility, and backup duration depend on the installation, inverter, and connected loads.
Plan your backup
Use the capacity buttons above, then adjust the average power of the appliances you want to keep running.
Add the average power of your selected appliances. Check each appliance label or manufacturer manual for watts. For cycling appliances, use average consumption over time.
Try an illustrative load:
Use the charge level you expect when an outage begins. Daily solar use or energy optimization may leave less than a full charge.
Try a starting charge or enter your own:
Use the typical length of an outage, or the period you want selected appliances to run.
Try a quick duration or enter your own:
Illustrative backup estimate
16.2 hours
At 500 W average load, 100% starting charge, and 10 kWh capacity.
| Capacity | Estimated hours |
|---|---|
| 5 kWh | 8.1 h |
| 10 kWhSelected | 16.2 h |
| 15 kWh | 24.3 h |
Capacity target for 6 hours at 100% starting charge
3.7 kWh estimated nominal capacity
5 kWh is the first listed option above this planning estimate.

Uses the selected starting charge, a 10% minimum energy reserve, 90% conversion efficiency, a constant average load, and no solar or grid input.
Hours = capacity in kWh × 1,000 × (starting charge fraction minus 0.10 reserve) × 0.90 efficiency ÷ average watts.
These are planning assumptions, not verified Leaf specifications. Real runtime varies with battery age, temperature, settings, inverter losses, and appliance use. This estimates energy duration only. It does not confirm that an inverter or battery can supply the load or appliance starting surge.
Prepare for sizing
Bring these to a conversation with Leaf so the recommendation can reflect your home, backup priorities, and existing equipment.
Ask Leaf about sizingList what must stay on, including any motor loads such as a refrigerator, pump, or air conditioner.
Note how often power cuts occur and how long they usually last.
Share details of rooftop solar, inverter, generator, meter, and available installation space.
Note the units (kWh) on a recent electricity bill, or your typical daily use if your meter or app shows it.
Note any planned air conditioner, pump, EV charger, or other major load that could change your backup priorities.
How Leaf works
Use rooftop solar or available grid power to charge your Leaf system.
Safe LFP cells hold energy quietly for the moments your home needs it.
Keep selected home loads running during outages or after the sun sets.
Follow charge, consumption, and system health through the Leaf app.
Built to fit
Leaf systems pair with leading inverter brands and are designed around local electrical conditions, installation practices, and service needs.
Residential battery backup
A residential battery stores electricity for later use. It can keep selected home loads running during an outage and make stored solar energy available after sunset.
Leaf systems are designed to pair with leading hybrid inverter brands, helping homes store daytime solar generation for evenings and interruptions.
Lithium iron phosphate chemistry is valued for thermal stability, long cycle life, and dependable performance in residential energy storage.
The right size depends on the appliances you want to support, their power draw, and the backup duration you need. Leaf offers 5, 10, and 15 kWh configurations.
