What does the FAULT: LED1=OFF, LED2=ON, LED3=ON, LED4=OFF (Green OFF, Red ON) error code mean?

FAULT: LED1=OFF, LED2=ON, LED3=ON, LED4=OFF (Green OFF, Red ON) on a Felicity unit indicates: Discharging Current High.. It is a fault-severity event that can appear on 2 different devices in the Felicity catalog. The same code may have slightly different recommended fixes depending on the device — the per-device sections below show the exact wording from each device's official manual.

This is a fault-severity code

Fault codes stop normal operation but the unit may attempt to recover. Common causes are out-of-range conditions (voltage, current, temperature) that require checking inputs and outputs before restart.

What triggers this code

FAULT: LED1=OFF, LED2=ON, LED3=ON, LED4=OFF (Green OFF, Red ON) is triggered when the unit's protection or monitoring logic detects the specific condition described above. The exact trigger depends on the device — see the per-device sections for the official manual entry for each.

FAULT: LED1=OFF, LED2=ON, LED3=ON, LED4=OFF (Green OFF, Red ON)Discharging Current High.Fault
Description

Discharge over-current protection has tripped; output is disabled.

Cause

Connected load drew more current than the recommended discharge limit (≤80 A) or sustained the 120 A 15 s peak too long, or a short-circuit on the DC bus.

Recommended fix

Remove or reduce the load, check for short circuits on the output wiring, and restart the pack. For loads above 6 kVA install at least 2 packs in parallel.

FAULT: LED1=OFF, LED2=ON, LED3=ON, LED4=OFF (Green OFF, Red ON)Discharging Current High.Fault
Description

Discharge over-current protection has tripped; output is disabled. Listed in the FAULT row of the LED table on page 7 as 'DISCHARGING CURRENT HIGH'.

Cause

Load drew more current than the recommended discharge limit (recommended <=120 A, MAX 200 A for 15 s per section 2.3) or a short circuit on the DC output. Section 1.3 item 11 warns NEVER to cause AC output / DC input short circuits.

Recommended fix

Remove or reduce the load, check the DC output wiring for short circuits, and restart the pack. For loads above 6 kVA install at least 2 packs in parallel (section 1.3 item 9). MAX. Output Power is 10 000 W; recommended output power is 6 000 W (section 2.3).
