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 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
G - Y - R (one cycle)
• Equalize start request
G / Y/ R - G / Y / R - G - G
• Equalize cancelled
G / Y / R - G / Y / R - R - R
• Battery service is required*
all three LEDs blinking until service is reset

Battery Status
• General state-of-charge
See battery SOC LED 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)
Faults & Alarms
