NOTE:
For multiple TriStar MPPT 150V controllers on a MeterBus
equalization using the TriStar meter so that all controllers are synchronized.
REMARQUE :
Avec plusieurs contrôleurs TriStar MPPT 150V sur un réseau MeterBusTM, initialisez une
compensation de batteries à l'aide de l'outil de mesure TriStar afin de synchroniser tous les
contrôleurs.
Note that if two or more TriStar MPPT 150V controllers are charging in parallel, each controller may
attempt to equalize on a different day. Systems with multiple controllers should only equalize manu-
ally to ensure synchronization between controllers.
4.4 LED Indications
Valuable information can be provided by the three LEDs visible through the front cover. Although
there are many different LED indications, they have similar patterns to make it easier to interpret each
LED display. Consider as three groups of indications: General Transitions // Battery Status // Faults &
Alarms.
LED Display Explanation
G = green LED is lit
Y - R = yellow LED is lit, then red LED is lit alone
G / Y = green and yellow are both lit at the same time
G / Y - R = green & yellow both lit, then red is lit alone
Sequencing LED patterns (faults) repeat until the fault is cleared
General Transitions
• Controller start-up
• Equalize start request
• Equalize cancelled
• Battery service is required
1
Battery service notification is only enabled in custom settings, or when any custom edit is programmed
1
Battery Status
• General state-of-charge
• Absorption state
• Equalization state
• Float state

all three LEDs blinking until service is reset
See battery SOC LED indications below
G blinking (½ second on / ½ second off)
G fast blink (2.5 times per second)
G slow blink (1 second on / 1 second off)
Operation
Faults & Alarms
• Over-temperature
• High voltage disconnect
• DIP switch fault
• Self-test faults
• Remote Temperature Sensor (RTS)
• Battery voltage sense
• Battery over-current
Battery State-of-Charge LED Indications
G
80% to 95% SOC
G / Y
60% to 80% SOC
Y
35% to 60% SOC
Y / R
0% to 35% SOC
R
battery is discharging
Refer to the Specifications (Section 8.0) for the State-of-Charge voltages.
Note that because these State-of-Charge LED displays are for all battery types and system designs,
they are only approximate indications of the battery charge state.
Ethernet Jack Indications
In addition to the SOC LEDs, two (2) small LEDs can be found on the Ethernet RJ-45 jack inside the
wiring box. These LEDs indicate the LAN/WAN network link and activity status as follows:
Condition
Network Connection OK
Network Activity

4.5 Protections, Faults & Alarms
The TriStar MPPT 150V protections and automatic recovery are important features that ensure the
safe operation of the system. Additionally, the TriStar MPPT 150V features real-time self diagnostics
that report Fault and Alarm conditions as they occur.
Faults are events or conditions that require the TriStar MPPT 150V to cease operation. A Fault usual-
ly occurs when a limit such as voltage, current, or temperature has been surpassed. Fault conditions
are indicated with unique LED sequences and are also displayed on the TriStar Meter.
