Battery level and load level LEDs
The battery level LEDs show the battery level both in back-up mode and in normal mode.
When the LED indicates 20% of the capacity in back-up mode, the Inverter is going to shut
down soon; the duration of backup time left depends on the load. When all five LEDs are
lighted in normal mode, the battery is fully charged.
The load level LEDs show the percentage of added load in relation to the Inverter’s rated
capacity. When all five LEDs are lighted, the Inverter is over loaded.
5.1.2
Operation status LED
The status LED shows the Inverter status. It lights in green when the utility power is normal
and in amber in the event of a utility outage (blackout); while if the Inverter is under fault
operation, it lights in red.
