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 section 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 equalization setting, an equalization will only occur when manually started with the pushbutton or when requested from the equalize menu on the TriStar meter. Automatic equalization will occur according to the battery program specified by settings switches 4, 5, & 6 in the previous step.
In both settings (auto and manual), the pushbutton can be used to start and stop battery equalization. If the selected battery charging setting does not have an equalization stage an equalization will never occur, even if requested manually.

Installation |
Step 5 - Remote Temperature Sensor
The included Remote Temperature Sensor (RTS) is recommended for effective temperature compensated charging. Connect the RTS to the 2-position terminal located between the pushbutton and the LED’s (see figure 2-1). The RTS is supplied with 33 ft (10 m) of 22 AWG (0.34 mm2) cable. There is no polarity, so either wire (+ or -) can be connected to either screw terminal. The
RTS cable may be pulled through conduit along with the power wires. Tighten the connector screws to 5 in-lb (0.56 Nm) of torque. Separate installation instructions are provided inside the
RTS bag.
!CAUTION:
The TriStar MPPT will not temperature compensate charging parameters if the RTS is not used.
CAUTION: Equipment Damage
!Never place the temperature sensor inside a battery cell. Both the RTS and the battery will be damaged.
NOTE:
The RTS cable may be shortened if the full length is not needed. Be sure to reinstall the ferrite choke on the end of the RTS if a length of cable is removed. This choke ensures compliance with electromagnetic emissions standards.
!Le TriStar MPPT ne compense pas la température des paramètres de charges si le RTS n’est pas utilisé.
PRUDENCE : Endommagement de l’équipement
!Ne placez jamais la sonde de température dans un élément de batterie. Le RTS et la batterie seraient endommagés.PRUDENCE :
REMARQUE :
Le câble de RTS peut être raccourci si la totalité de la longueur n’est pas nécessaire. Assurezvous de réinstaller la bobine en ferrite sur l’extrémité du RTS si une longueur de câble est enlevée. Cette bobine assure la conformité avec les normes d’émissions électromagnétiques.
