1. Why Off-Grid Battery Selection Is Different
Off-grid systems require:
- Deep discharge capability
- High reliability
- Long backup time
👉 Battery is your only power source at night
2. Key Requirements
- DoD ≥ 80%
- Cycle life ≥ 4000
- Stable performance
👉 LiFePO4 is the best option
3. How to Size Off-Grid Battery
Step 1: Daily load
Step 2: Backup days (usually 1–3 days)
Example:
- 10 kWh/day × 2 days
👉 20 kWh
4. Important Design Tips
- Always oversize battery
- Plan for bad weather
- Ensure inverter compatibility
5. Common Mistakes
- Undersizing battery
- Choosing lead-acid
- Ignoring weather conditions
6. Recommended Configuration
👉 Solar + LiFePO4 + hybrid inverter
