Basic Setup Overview: Morningstar DIP Switch Settings by Product and
Type of Settings Aquion1 Aquion2 Notes:

  • Custom settings are recommended for best results. However, there are
    factory PreSets that can be enabled with alternative DIP Switch settings
    which may be applicable for a particular model, system and environmental
    conditions.
  • Different controllers will have different options and charging
    parameters. Please use the information below and make adjustments as needed.
    Not all settings critical and certain conditions may or may require some of
    the optional settings. Review all of the settings and consider what
    adjustments may be required for your particular system.
  • Max. Charge Limits can be imposed for the TriStar MPPT and ProStar MPPT
    controllers. The downloadable MSView Setup Wizard files for the TriStar MPPT
    and ProStar MPPT controllers have Enabled Battery Current Limits for a single
    battery stack. These settings can quickly be edited in MSView for multiple
    stacks if there are multiple stacks or modules.
  • All custom settings must be programmed with 12V nominal voltages which
    will be multiplied accordingly for 24V and 48V battery banks. DIP Switch
    nominal voltage multiplier settings are recommended.
  • Charging can be reduced and disabled during low temperatures with the
    ProStar and ProStar MPPT controllers. The Morningstar Relay Driver can be
    used to disable both charging and loads during cold temperatures.

Custom Settings for Aspen 48S-2.2, 48M-25.9, 24S-83
Different controllers will have different options and charging parameters.
Please use the information below and make adjustments as needed. Not all
settings critical and certain conditions may or may require some of the
optional settings. Review all of the settings and consider what adjustments
may be required for your particular system. Charge Mode – Absorption &

    24S-83)
  • Load Settings (TriStar in Load Mode, ProStar, ProStar MPPT,
    SunSaver MPPT or )
  • Low Voltage Disconnect10-11V (or as needed for
    load)

  • Delay Before LVD5 min
  • Load Current Compensation … 0.05 @48V/0.033 @24V ohms (V/A) [= -1V
    @20A/= -1V @30A]

* – Settings must be programmed with 12V nominal voltages with all
Morningstar controllers and will be multiplied by 2 or 4 for 24V and 48V
batteries respectively. Use DIP Switches to set the battery voltages as
indicated in the DIP Switch tables above.

** – Float Timeout is the cumulative time that voltage drops below the
Float Target Voltage before returning to Bulk/Absorption. If a system drops
out of float this setting will attempt to recharge the battery late in the
day

*** – High Voltage Disconnect/ Reconnect will disable charging when there
is overcharging from other sources.

Tristar – TS‐60 (60A), TS-45 (45A) Special Considerations

  • Chose a TriStar Mode – Solar/ Diversion
  • Solar Charge Control checked
  • Charge Mode – Float Settings
  • Enable Float checked
  • Float Voltage .. 13.7 V
  • Transition to Float when duty cycle is ….. 98% or less for 4 hrs
    (Diversion – After 4 h in Absorption (d > 0%)…)
  • Exit Float when duty cycle is 100% for 2 hr (Diversion
    – Exit Float if d=0% for a cumulative 2h)
  • Enable Low battery trip Disable
  • Enable Float cancel Voltage Disable
