Building a Battery Bank
These batteries can be connected in series to build higher-voltage systems:
- 12V System: 6 × 2V batteries
- 24V System: 12 × 2V batteries
- 48V System: 24 × 2V batteries
Important Battery Installation Notice
Do not mix new and old batteries in the same battery bank.
For best performance, batteries connected in the same bank should be of the same model, capacity, age and condition. Please contact us if you require assistance designing a complete battery bank.
Applications
- Off-grid solar systems
- Residential and commercial energy storage
