4.4 LED Indications
Valuable information is 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.

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 notification is only enabled in custom settings
Battery Status
• General state-of-charge see battery SOC indications below
• Absorption
G blinking (once per second)
• Equalization state
G fast blink (two times per second)
• Float state
G slow blink (once per two seconds)
Faults & Alarms
• Over-temperature
Y - R sequencing
• High voltage disconnect G - R sequencing
• DIP switch fault
R - Y - G sequencing
• Self-test faults
R - Y - G sequencing
• Remote Temperature Sensor (RTS)
G / Y - Y / R sequencing
• Battery voltage sense
G / Y - Y / R sequencing
• Solar Over-Current
Y / R - G sequencing
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

Note that because these State-of-Charge LED displays are for all battery types and system de-
signs, 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:
