TriStar Manual

Operation

NOTE:

For multiple TriStar MPPT 150V controllers on a MeterBus

network, initialize a battery

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 an 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

manually 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

G+Y = Green and Yellow are both lit at the same time

R+Y / G = Green & Yellow both lit, then Red is lit alone

Sequencing LED patterns (faults) repeat until the fault is cleared

General Transitions

• Controller start-up G / Y / R (one cycle)

• Equalize request start G+Y+R / G+Y+R / G / G

• Equalize cancelled G+Y+R / G+Y+R / R / R

• Battery service is required* all 3 LEDs blinking until service is reset

*battery service notication is only enabled in custom settings

Battery Status

• General state-of-charge see battery SOC indications below

• Absorption state G blinking (½ second on / ½ second off)

• Equalization state G fast blink (2.5 times per second)

• Float state G slow blink (1 second on / 1 second off)
