eVault Max 18.5kWh Lithium Ferro Phosphate (LFP) Installation

Charger/Inverter conguration recommendation for best Performance:
The Battery Parameter Setting Guides with SMA, Sol-Ark, Schneider and Outback Inverters/Chargers
are available to download on www.fortresspower.com/Resource
Recommended operating parameters of charger/Inverters For 3,000 Cycles:
• Operating temperature range: 32°F to 120°F (0°C to 49°C)
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 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.
7. DIAGNOSTIC GUIDE
The smart eVault Max BMS provides multiple level protection function:
• Over Charge Voltage Protection
• Over Discharge Protection
• Over Current Protection for Discharge Via Thermal Control
• Short Circuit Protection
• ON/OFF Switch
• In the event of a fault the battery protection circuit will open its internal relays disconnecting the negative
battery terminals form the internal cells. The battery uses relays and precautions should be taken to reduce
voltage spikes and large inductance in the application.
When an Incident occurs or an alarm light is on, please follow this guide as the initial step in the troubleshooting
process.
1. Please isolate the battery:
a. Turn OFF main Air Breaker on top of the battery
b. Remove all external power sources to/from battery
2. Make sure Battery Voltage is consistent with LCD Display:
a. Turn ON main Air Breaker on top of the battery
b. Use an available Multimeter to measure the voltage at top of the terminals
i. If consistent with LCD Display, please measure the voltage of each battery cell
• Please see Restart BMS by pushing the POWER Button for at least 10s
• If Alarm Light persists, see “Measure Cell Voltages Manual” in order to remove the back case of the
unit and measure each of its cell voltages
ii. If inconsistent, please use the BMS Adapter Cable along with BMS Tool Software
• Once the BMS Tool Software is running, check what Alarm is currently active
• Follow “Troubleshooting Manual”
3. If Problem persists, please contact Fortress Power Tech Support
