The main concern for rural microgrid batteries is the amount of useful energy capacity and the ability to scale up capacity to meet autonomy needs. The battery’s charge/discharge efficiency and useful energy versus system design life calculation will have a significant impact on the project’s economics.
- Lowest total lifetime cost
- LiFePO4 cell technology
- Recommended useable SoC 10%– 90%
- Partial State of Charge use recommended
- ≧15-year daily cycle design life at 80% DoD
- >10x the IEC61427 endurance life of lead-acid
- Medium up-front cost
- OPZ tubular plate technology
- Recommended useable capacity 50%
- Partial State of Charge use decreases life
- ≦8-year daily cycle design life at 50% DOD
- <2600 PSOC cycle life (IEC 61427)
