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.
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
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 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 to 3 times per second)
• Float state G slow blink (1 second on / 1 second off)
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
Refer to the Specications (Section 9.0) for the State-of-Charge voltages.
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:
Condition Yellow LED Green LED
Network Connection OK ON OFF
Network Activity ON Blinking
Error OFF ON
