FAQ

1. How do I choose the right capacity for my home energy storage system?

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.

2. What capacity and inverter size are recommended for different home types?

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

3. How can a home energy storage system support backup during outages?

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.

4. Can I start small and expand my energy storage system later?

Yes. Modular battery systems allow starting with 5 kWh and expanding to 30 kWh or more as your energy needs grow.

5. What configuration is recommended for farms or rural homes?

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.

  • Battery Capacity: 30–60 kWh
  • Inverter Power: 10–15 kW
  • Solar Array: 10–20 kW

6. What are typical power consumption and daily energy use of household appliances?

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

7. How does climate affect my choice of energy storage system?

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.

8. How do I balance solar self-consumption and grid backup?

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.

9. Can homes go fully off-grid with these systems?

Yes, with battery capacities above 30 kWh and proper load management, fully off-grid homes are achievable.

10. What is Depth of Discharge (DoD), and why is it important?

DoD indicates how much battery capacity can be safely used. LFP batteries support ≥90% DoD, improving usable capacity and battery life.

11. How to choose the right inverter power for my home?

  • Inverter power should cover peak simultaneous loads.
  • Select inverter rated 1.2–1.5 times your max household load.
  • Larger inverter power is better if many heavy appliances run simultaneously.

12. What other factors affect system configuration?

  • Existing solar PV installation
  • Frequency and duration of power outages
  • Load stability and fluctuations
  • Available installation space and cooling conditions
  • Budget and plans for future expansion
