LED Status Indicators

Battery LEDs

Three LEDs provide a visual reference to indicate the condition of the battery bank.
 A GREEN LED means the batteries have an adequate charge at that time. It does not always mean they
are full. If an FNDC is installed, this means the batteries are  80% .
 A YELLOW LED means the batteries are somewhat discharged. If an FNDC is installed, this means the
batteries are  60% and  70% .
 A RED LED means the batteries are greatly discharged and may require attention. If an FNDC is
installed, this means the batteries are < 60% . May be accompanied by an event indicator and a
Low Battery V error. (See pages 23 and 40.)

Gaps in the table (higher-voltage units) are due to the resolution of the inverter's DC meter.

These voltage settings are not the same as the inverter's Low Battery Cut-Out (LBCO) voltage.
The Battery LED settings cannot be changed.

Inverter LED (green)

This LED is located on the INVERTER hot key. (See page 47.) It provides a visual reference for the status
of the inverter operation.
 ON (solid) — inverter is converting DC to AC in order to power loads.
 ON (flashing) — the inverter is in Search mode.
 OFF (not illuminated)
~ the inverter is not converting DC power to AC power, or
~ the AC input source is powering the loads.
If any inverters in a stacked system have a different inverting status from the master, this LED will not
display their status.

Charger LED (yellow)

This LED is located on the CHARGER hot key. (See page 48.) It provides a visual reference for the status
of the battery charger.
 ON (illuminated) — a device on the HUB is in one of the active stages for charging batteries. The
device may be an inverter or a charge controller.
 ON (flashing) — the batteries are being equalized.
 OFF (not illuminated) — no device is actively charging the batteries, for several reasons.
~ the charger(s) may be functional, but in a quiescent state such as Silent.
~ the charger(s) may be functional, but the charging sources may be disconnected or unavailable.
~ the charger(s) may be turned off.
