🔋 Introduction
Battery usage differs significantly between:
- Off-grid systems
- On-grid (hybrid) systems
👉 And this directly impacts lifespan.
⚖️ Key Difference
| System Type | Usage Pattern |
|---|---|
| Off-grid | Daily full cycling |
| On-grid | Partial/backup use |
📊 Lifespan Comparison
Off-Grid
- 1 cycle/day
- High DOD
👉 Shorter lifespan (relative)
On-Grid
- Occasional cycling
- Lower DOD
👉 Longer lifespan
🔍 Real Example
Off-grid system:
- 5000 cycles → ~13 years
On-grid system:
- Fewer cycles/year
👉 Can last 15+ years
⚡ Key Insight
👉 Usage pattern matters as much as battery quality
💡 Optimization Tips
For Off-Grid:
- Control DOD
- Proper sizing
For On-Grid:
- Avoid unnecessary cycling
- Maintain SOC range
