11. Verify with your utility company that grid frequency is within the regulated
range.
7.3 Disconnect Microinverters from PV Modules
If your problems are still unsolved with the steps above, please contact
Envertech tech support through www.envertec.com. If Envertech approves the
replacement, please take off the microinverter according to the following
instructions. In order to ensure the disconnection between the microinverter
and the PV Module will not be done while the microinverter is at working status,
please strictly follow the steps below.
1. Turn off AC branch circuit breaker.
2. Disconnect the microinverters in the following procedure.
Pull the AC connectors of both sides of the microinverters in the opposite
direction with appropriate force.
3. Cover the PV module with an opaque, and then disconnect the PV module DC
connectors from the microinverter.
4. Loosen the grounding screw and remove the grounding wire.
5. Take off the microinverter from the PV frame.
