Switches 4, 5, & 6: Battery Charging Settings
It is important to select the battery type that matches the system battery to ensure proper charg-
ing and long battery life. Refer to the specifications provided by the battery manufacturer and
choose a setting that best fits the recommended charging profile.

All settings are for 12 Volt nominal systems. Multiply the charge voltage settings by 2 for 24 Volt
systems or by 4 for 48 Volt systems. A description of each setting is provided below. See sec-
tion 4.3 for full details on battery charging and a description of each of the settings in the battery
charging table.
Battery Type
- The most common battery type associated with the specified charging settings.
Absorption Stage - This stage limits input current so that the Absorption voltage is maintained.
As the battery becomes more charged, the charging current continues to taper down until the
battery is fully charged.
Float Stage - When the battery is fully charged, the charging voltage will be reduced to the Float
voltage setting.
Equalize Stage - During an equalization cycle, the charging voltage will be held constant at the
specified voltage setting.
Equalize Interval - The number of days between equalization charges when the controller is con-
figured for automatic equalizations (settings switch 7).
Switch 7: Battery Equalization
Choose between manual and automatic battery equalization charging. In the manual equaliza-
tion setting, an equalization will only occur when manually started with the push-button or when
requested from the equalize menu on the TriStar meter. Automatic equalization will occur accord-
ing to the battery program specified by settings switches 4, 5, & 6 in the previous step.
In both settings (auto and manual), the push-button can be used to start and stop battery equal-
ization. If the selected battery charging setting does not have an equalization stage an equaliza-
tion will never occur, even if requested manually.

Switch 8: Ethernet Security
The Ethernet Security switch enables or disables configuration of the TriStar MPPT 150V settings
through the Ethernet connection. When switch eight is set to
disabled
, write commands to the
TriStar MPPT 150V custom memory are not allowed. This a safety feature to prevent unintended
changes to custom settings, but it is not a replacement for proper network security.
Configuration via TCP/IP

NOTE:
Adjustment of network settings and custom set-points is always enabled via the
RS-232 and EIA-485 connections. The Ethernet Security switch only enables/
disables remote configuration via TCP/IP.
!
CAUTION: Risk of Tampering
The Ethernet Security settings switch does not block write commands to devices
bridged via EIA-485.
REMARQUE :
Le réglage des paramètres de réseau et des points de consignes personnalisés
est toujours activé par les connexions RS-232 et EIA-485. Le contacteur de
sécurité Ethernet n’active/désactive que la configuration à distance par TCP/IP.
!
PRUDENCE : Risque de tentative d’altération
Le contacteur des paramètres de sécurité Ethernet ne bloque pas les
commandes d’écriture sur les dispositifs reliés par EIA-485.
