approximately 3.0 W from the battery.
5.2 Input Level (battery voltage) indicator
The GPSW600, GPSW1000, GPSW2000 and GPSW3000 Input Level LED
changes colour from green to yellow to red as battery voltage decreases from a
resting voltage of 12.7 V - 10.5 V (12 V) or 25.4 V – 21V (24 V). The Input Level
LED changes colour from green to yellow to red as battery voltage increases
from a resting voltage of 12.7V – 15.0 V (12 V) or 25.4 V – 30.0 V (24 V).
5.3 Load Level Indicator
The Load Level LED Indicator changes color from green to yellow to red as the
load is increased. The Load Level LED Indicator will be red at peak wattage or
peak load.
The Load Level LED Indicator should be green or yellow for long-term operation.
Short-term operation is possible with the load indicator in the red area. If the load
rises to dangerous levels, the inverter will protect itself and shut down.
5.5 Status Indicator (GPSW1000, GPSW2000 and GPSW3000)
The status LED indicator will display the operating condition of the inverter. A
solid green LED is normal. A flashing green LED indicates the inverter is in
power save mode (see Power Saving). A red LED, flashing or otherwise,
indicates a fault; see
Table 1: Inverter power states
State LED Description
Over voltage
protection Red LED blinking
fast Over voltage protection indicates
that the inverter has shut itself down
because its input voltage is over:

12 V: 15.0 ~ 16.0 V DC
24 V: 30.0 ~ 32.0 V DC
Under voltage
protection Red LED blinking
slowly Under voltage protection indicates
that the inverter has shut itself down
because its input voltage is lower
than:

12 V: 10.0 ~ 10.5 V DC
24 V: 20.0 ~ 21.0 V DC
