Troubleshooting

If the IQTM Battery(ies) are not operating correctly, do the following. If the issue persists, contact Enphase at enphase.com/en-us/support/contact.

A ) If the IQTM Battery(ies) do not operate, check the temperature in the room

and increase cooling and/or ventilation as required. Check that the front, and top sides of the IQTM Battery 3T and IQTM Battery 10T have at least 15cm (six inches) of unobstructed clearance.

B ) If the IQ

Battery LED is off, turn off the breaker for the branch circuit, wait

for at least one minute, and turn it back on.
