4.8 LCD SCREEN AND ALARM WARNINGS
The LCD display on the front of eVault Max provides Battery Voltage (V), Charging and Discharging Current
(A), State of Charge (SOC), as well as Charging and Discharging Power Output (kW). Please note, when the
battery is charging, the Current (A) will show a negative value, while during the discharging the Current (A) is
positive.
The green light (RUN) indicates system is running properly.
The red alarm light (ALARM) will turn on, if the battery experiences one of those scenarios: High voltage (HV);
Low voltage (LV); HT (High Temperature): LT (Low Temperature); Open Circuit (OC) and Short Circuit (SC).
KEY POINTS SUMMARY:
1. Each eVault Max contains a sophisticated Battery Management System that protects the Lithium-Ferro
Phosphate cells from overcharging, over-discharging, and excessive load amperage. If the values specified
are exceeded, the battery will enter a protective shut down state. In some cases, this may result in the
need to re- initialize an inverter charger or other pieces of equipment in the installation. In other cases,
the inverter’s system settings may be saved within the inverter memory storage and will not need to be
reset. This is not an absolute standard but is common among most inverter chargers. Check your inverter
manufacturer specifications.
2. If the battery enters a self-protective mode, negligible voltage readings will be present until the unit is
reset. In some instances, after a prolonged shut down, a charge might need to be manually applied to the
energy storage bank. Should this occur, please contact Fortress Power for technical support.
3. Although each eVault Max contains circuitry that protects the Lithium Ferro Phosphate cells from
overcharging, over-discharging and excessive load amperage, the eVault Max must always be installed with
a charge controller and the appropriate settings to protect the batteries from open PV and other high
voltage sources.
4. GRID TIED SYSTEMS: Once the eVault Max has been installed, turn on the entire system to test. Once
testing has been completed, please disconnect the batteries from the load center until your local Utility
Inspector grants Permission to Operate the entire system. The charge controllers and inverter monitoring
systems can drain the eVault Max over an extended period when the entire system is not fully operational
due to the electrical draw of the system components.
5. OFF GRID SYSTEMS: Do not connect the eVault Max until the entire system is ready to turn on and is fully
operational.
6. See the equipment integration guides on our website for details on programming your system. The eVault
Max are compatible with most 48V Inverter/Chargers and Charge Controllers. Please contact Fortress Power
to learn the recommended settings for any device not explicitly covered in this manual.
