How do I fix Very Low SoC — Recovery Mode on a Enphase?

Allow grid to recharge battery. This is a protection state — do not attempt to force discharge. Monitor SoC in Enlighten Then: Review minimum SoC reserve setting. Consider increasing Storm Guard reserve if grid outages are common

Enphase

Low SoC Rcv

Very Low SoC — Recovery Mode

Battery SoC has fallen below the deep discharge threshold. Battery is in recovery mode and will only accept charge, not discharge.

Common causes

Extended grid outage with high load draining batteryMinimum SoC reserve set too lowUnexpected overnight discharge

What to check

STEP 1

Allow grid to recharge battery. This is a protection state — do not attempt to force discharge. Monitor SoC in Enlighten

STEP 2

Review minimum SoC reserve setting. Consider increasing Storm Guard reserve if grid outages are common

Escalate if

Battery does not accept charge after grid restore — possible deep discharge cell damage, escalate
