WARNING
: Do not attempt to repair the Plugreen Solar micro-inverter; it contains no user-
serviceable parts. If troubleshooting methods fail, please return the solar micro-inverter to your
distributor for maintenance.
Disconnecting the Plugreen Solar micro-inverter from the PV Module
To ensure that the solar micro-inverter is not disconnected from the PV modules under load, adhere to
the following disconnection steps in the order shown:
Disconnect the AC by opening the branch circuit breaker.
Disconnect the first AC connector in the branch circuit.
Cover the module with an opaque cover.
Using a DC current probe, verify there is no current flowing in the DC wires between the PV
module and the solar micro-inverter.
Care should be taken when measuring DC currents, most clamp-on meters must be zeroed
first and tend to drift with time.
Disconnect the PV module wire connectors from the Solar micro-inverter
Remove the Solar micro-inverter from the PV array racking.
