Operation
3–14 975-0012-01-02 Rev A
Whenever the battery voltage drops to its lowest (safe) level (as calculated by the
ODP), the LED lights green to indicate the condition. If the condition persists, the
inverter will shut down until the battery voltage returns to a safe level and then
restart.
Charger LED - Orange / Green
The Charger LED is a dual color (red/green), triple function indicator.
• When the charger is in Bulk mode, the LED lights orange.
• When the charger is in Absorption mode, the LED blinks orange.
• When the charger is in Float mode, the LED lights green.
Audible Indicator (internal)
A buzzer is located on the control board as an audible alert to fault conditions such
as Battery High/Battery Low, or Overload. Steady buzzing indicates an impending
inverter shut down. A pulsing chirp indicates the inverter is temporarily off-line
due to a fault condition (either within the inverter or related to the system).
Important:
In renewable energy applications (solar, wind, hydro, etc.) the DC charge
controllers must be set to a level below the inverter’s maximum input voltage or the
inverter shuts OFF.
Important:
The inverter automatically restarts when the following error conditions are
detected: LOW/HIGH BATTERY, OVER TEMPERATURE, or a quick duration
SHORTED OUTPUT or OVER-CURRENT. The inverter shuts OFF and requires a
MANUAL restart if the following conditions are detected: a prolonged overload condition
(approximately 10 seconds) or the inverter’s output is connected directly to an AC power
source (utility grid or generator).
Important:
Orange is a flickering mix of red and green. It can look different depending
on the angle at which the LED is viewed. It should never be a solid red.
Important:
The battery charger control circuit operates from the battery voltage. If the
battery voltage falls below 7 volts, the inverter/charger will not operate. The batteries
must first be recharged using a stand-alone charger to bring the voltage up to a level where
the inverter/charger can operate.
