Understanding Charge Stage
1. Bulk Charge: Charge at Constant
Current (CC) to Bulk/Absorb Voltage
2. Absorption Charge: Maintain
Constant Bulk/Absorb Voltage (CV)
3. Terminate when charge current
drops below 0.05C
4. Unlike Lead Acid batteries, Lithium
Ferro Phosphate batteries do not
require Float Charge
Charger/Inverter configuration recommendation for best Performance:
Note: For inverter-specific integration manuals, visit www.fortresspower.com/Resources
Recommended operating parameters of charger/Inverters For 3,000 Cycles:
Operating temperature range: 32 F to 120 F (0 °C to 49°C)
Bulk voltage and absorb voltage should be set to 54.4V
Recommended operating parameters of charger/Inverters For 6,000 Cycles:
Operating temperature range: 50 F to 110 F (10°C to 43°C)
Storage must be equal to or more than twice the rated output of the Inverter
Bulk voltage and absorb voltage should be set to 54.4V
At the End of Cycle Life capacity is Equivalent to 70% Retained Capacity
CAUTION! Do Not Operate Fortress Lithium Batteries at an average temperature
exceeding 30 °C / 86 °F over the life of the battery.
