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

Check SoC in Enlighten. If at minimum reserve (default 20%), battery is protecting itself — increase PV/grid charge first Then: Check Enphase app for Storm Guard or Reserve settings. Confirm discharge schedule is enabled for current time period

IQ Battery Not Discharging

IQ Battery 5P will not discharge to support loads or export.

Common causes

Battery SoC is at or below the minimum reserveStorm Guard/Grid Outage Reserve is activeDischarge schedule not configuredBattery temperature fault

What to check

STEP 1

Check SoC in Enlighten. If at minimum reserve (default 20%), battery is protecting itself — increase PV/grid charge first

STEP 2

Check Enphase app for Storm Guard or Reserve settings. Confirm discharge schedule is enabled for current time period

Escalate if

SoC is above reserve, no Reserve mode active, but battery still will not discharge — escalate
