How do I fix IQ Battery Not Reporting on a Enphase?

Check IQ Combiner and IQ System Controller LEDs — should be solid green. Check battery LED status on the unit Then: Check PLC communication cable from battery to combiner. Power cycle the system (battery off → combiner off → wait 60 s → restore)

Enphase

Bat Not Rep

IQ Battery Not Reporting

IQ Battery 5P has not communicated with the IQ Gateway within the expected interval.

Common causes

IQ Combiner or IQ System Controller not poweredCommunication cable fault between battery and GatewayBattery powered offFirmware update in progress

What to check

STEP 1

Check IQ Combiner and IQ System Controller LEDs — should be solid green. Check battery LED status on the unit

STEP 2

Check PLC communication cable from battery to combiner. Power cycle the system (battery off → combiner off → wait 60 s → restore)

Escalate if

All hardware is powered and communication cable confirmed — escalate with battery serial number
