INVERTER/CHARGER CONFIGURATION:

A PDF manual with settings for SMA, Sol-Ark, Schneider, Outback and other Inverters/Chargers is available

for download at our website.

For a detailed breakdown of operating conditions and how they can affect battery life and the 10 (5) year battery

warranty please see the eVault Max Warranty document on our website.

CAUTION! Do Not Operate the eVault Max at an average temperature exceeding 30°C

/ 86°F over the life of the battery.

7. DIAGNOSTIC GUIDE

The eVault Max BMS provides multiple levels 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.

Over Voltage Fault

58.4±0.4V

Over Voltage Recovery

54.0±0.4V

Low Voltage Fault

43.2±0.4V

Low Voltage Recovery

43.2±0.4V

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 DC 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 DC 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 the problem persists, please contact Fortress Power Tech Support
