Introduction
Many residential solar failures are caused by avoidable configuration errors.
1. Mixing Old and New Batteries
Different internal resistance leads to uneven charging and early failure.
2. Excessive Depth of Discharge
Regular deep discharge below 50% DOD drastically reduces lifespan.
3. Ignoring Temperature Effects
Uncontrolled environments accelerate aging.
4. Poor Wiring Design
- Uneven cable length
- Insufficient cable thickness
- Poor terminal crimping
5. Lack of Monitoring Systems
Battery monitoring systems help detect problems early.
