Morningstar Integration Guide
Note: For information regarding module system configuration options, please contact the energy storage manufacturer.
For optimal integration, the recommended settings (based on 12V nominal values) are as follows:
Critical Settings:
Absorption Voltage = 13.85 V
Absorption Time = 6 min
Temperature Compensation = 0.0 V/degC (Disabled)
Float/Float Voltage/Timeout = Enable/13.60 V/30 min (Float stage not required while battery is in
storage)
Equalize = Not enabled
Battery HVD/High Voltage Disconnect/Reconnect = Enable/14.20 V/13.80 V
Load LVD (Low Voltage Disconnect) ………………………………….. 12.00 V
Load LVR (Low Voltage Reconnect) …………………………………….. 13.20 V
Note:
Many lithium batteries include a BMS that can implement an internal battery disconnect in the event of a deep discharge to
prevent permanent damage to the battery chemistry. It is important that proper low voltage load disconnect settings are used
to prevent this from occurring during charging. Damage to the controller due to a battery disconnect during charging is
typically not covered under warranty. Incidental damage to loads is also not covered under warranty.
Optional Recommended Settings:
Absorption Ext = Not enabled
Battery Service Reminder = Not enabled (Monitor Ah capacity with external shunt measurement)
Max Regulation Limit = Not enabled
Battery Current Limit = Optional (LFP-10: 80A max per battery, 50A per battery recommended/ eVault
16.5: 150A max per battery, 100A per battery recommended)
Delay Before Load LVD …………………………………………………………... 1 min (Possibly longer for cold
temperatures)
