📐 How to Choose the Right Lithium-ion Inverter Battery
✅ Know Your Power Requirement
Start by estimating the total wattage of devices you’ll power during a blackout. This helps in selecting the right battery capacity and inverter size.
| Appliance | Typical Wattage |
|---|---|
| LED Bulb (5–9W) | 9W |
| Ceiling Fan | 60–80W |
| Laptop | 100W |
| TV (32” LED) | 60W |
| WiFi Router | 10W |
| Refrigerator (Medium) | 150–300W |
| Water Pump (0.5HP) | 370W |
| Washing Machine (Spin) | 400–500W |
| Microwave Oven | 1000–2000W |
| Induction Cooktop | 1500–2000W |
| Electric Geyser | 2000–3000W |
| 1.5 Ton Air Conditioner | 1200–1800W (2500W start) |
⚠️ Note: High-wattage appliances like ACs, geysers, and cooktops require high-capacity inverters (3kW–5kW) and large lithium battery banks (e.g., 48V 100Ah or higher). Avoid using them on regular backup systems unless designed for it.
✅ How to Calculate Inverter Battery Backup Time
🔍 SEO Keywords integrated: inverter battery backup time calculation, how to calculate battery backup, lithium battery backup for inverter, inverter battery backup hours
To ensure your lithium inverter battery meets your needs, calculate the estimated backup duration using this formula:
🧮 Battery Backup Time (hours) = Battery Capacity (Wh) ÷ Load (W)
Example:
- Battery: 48V 40Ah → 48 × 40 = 1920Wh
- Load: 500W
→ Backup: 1920 ÷ 500 = ~3.8 hours
| Battery Size | Load (W) | Backup Time (Approx.) |
|---|---|---|
| 48V 40Ah (1920Wh) | 500W | 3.8 hours |
| 48V 60Ah (2880Wh) | 1000W | 2.8 hours |
| 48V 80Ah (3840Wh) | 800W | 4.8 hours |
✅ A larger lithium-ion battery for inverter gives you longer power backup.
⚠️ For solar inverter battery backup, ensure the battery supports both solar PV and grid charging. Always calculate with a 20% safety margin for efficiency losses.
✅ Step 3: Select Battery Voltage & Capacity
| Inverter System | Battery Voltage | Recommended Capacity |
|---|---|---|
| Small Home (500–1000W) | 24V or 48V | 24V 50Ah / 48V 25Ah |
| Medium Home / Office | 48V | 48V 40Ah – 60Ah |
| Commercial / Heavy Use | 48V / 60V | 48V 80Ah – 100Ah |
