1. When to Use Series Connection
Choose series when you need:
- Higher system voltage (24V, 48V, 96V)
- High-power inverters
- Low current and reduced cable loss
- Industrial-scale storage systems
Typical applications:
- Telecom base stations
- Solar hybrid systems
- UPS backup systems
2. When to Use Parallel Connection
Use parallel for:
- Increasing total energy capacity
- Long backup time in home systems
- Low-voltage storage (12V systems)
Applications:
- Small off-grid cabins
- RV and marine systems
- Low-power backup banks
3. When to Avoid Parallel or Series
Avoid large series strings if:
- Battery quality varies
- Regular maintenance is difficult
Avoid large parallel groups if:
- Cable management is poor
- Batteries age at different rates
4. Combined Series-Parallel Systems
Many professional energy storage systems use both:
- Parallel groups to increase Ah
- Series strings to reach system voltage
This delivers balanced performance with optimized power output.
Conclusion
Choosing the correct configuration depends on voltage requirements, system size, expected cycle life, and maintenance conditions. Proper matching and maintenance are essential regardless of the connection type.
