7.4 Parameter set up guide in Charger/Inverter
Before commissioning the energy storage system, the appropriate controller and inverter settings must
be programmed per the manufacturer’s recommendations. Consult the manufacturer’s manuals and/or
access technical support (Darfon, Schneider, Outback, SMA, Sol-Ark, Magnum, Outback).
Although Fortress Lithium batteries can perform at very high rates and depths of discharge within a
very wide temperature range, in order to achieve extended life cycles and to comply with the Warranty,
the following guidelines should be followed:
Understand 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

Recommended operating parameters of charger/Inverters For 3,000 Cycles:
• Operating temperature range: 35 F to 120 F (2 °C to 49°C)
Recommended operating parameters of charger/Inverters For 6,000 Cycles:
• Operating temperature range: 35 F to 110 F (2°C to 43°C)
• Storage must be equal to or more than twice the rated output of the Inverter
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.
