Capacity depends on your daily electricity consumption, number of rooms, and appliances. For a typical 3-bedroom home, 10–15 kWh is usually sufficient, while larger villas or farms may require 30 kWh or more.
| Home Type | Daily Consumption (kWh) | Recommended Battery Capacity | Recommended Inverter Power |
|---|---|---|---|
| Small Apartment | 8 – 12 | 5 – 10 kWh | 3 – 5 kW |
| Medium Home | 12 – 20 | 10 – 15 kWh | 5 – 8 kW |
| Villa | 20 – 35 | 15 – 30 kWh | 8 – 12 kW |
| Farm / Rural Home | 25 – 60 | 30 – 60 kWh | 10 – 15 kW |
For basic backup like lighting and refrigeration, a 5–10 kWh battery can provide 6–12 hours of power. Whole-home backup with HVAC and appliances typically requires 15–30 kWh capacity.
Yes. Modular battery systems allow starting with 5 kWh and expanding to 30 kWh or more as your energy needs grow.
A setup with 30–60 kWh battery capacity, 10–15 kW inverter, and 10–20 kW solar array reliably powers farm equipment, irrigation pumps, and household loads.
| Appliance | Power (W) | Daily Usage (h) | Daily Energy (kWh) |
|---|---|---|---|
| Refrigerator | 150 | 24 | 3.6 |
| Air Conditioner | 1500 | 6 | 9.0 |
| Washer/Dryer | 2000 | 1.5 | 3.0 |
| LED Lighting | 300 | 6 | 1.8 |
| TV + Router | 200 | 5 | 1.0 |
In sunny regions, smaller capacities (5–10 kWh) may suffice, while cloudier or colder areas should consider larger capacities (15–30 kWh) for reliable power.
A hybrid system with 5–15 kW solar, 5–10 kW inverter, and 10–20 kWh storage maximizes solar use and provides backup during outages.
Yes, with battery capacities above 30 kWh and proper load management, fully off-grid homes are achievable.
DoD indicates how much battery capacity can be safely used. LFP batteries support ≥90% DoD, improving usable capacity and battery life.
