7.1 Energize the System
1. Turn on the switch or the circuit breaker at each microinverter AC branch.
2. Turn on the main AC circuit breaker in the distribution box. Your system will
start to produce power after 3 minutes.
3. Envertech microinverters begin to communicate through the power lines to
EnverBridge. The entire system will be detected within 10 minutes.
4. The voltage and frequency of EVT2000 can be adjusted on the site. If
adjustments are required by your local utility company, installers can use
EnverBridge to manage grid parameters after all microinverters have been
detected.
7.2 EVT2000 Operation
The Envertech microinverter is powered on when there is sufficient DC voltage
from the PV module. The LED light of each microinverter will blink green to
indicate normal start-up operation approximately 1 minute after DC power is
applied.
8. Troubleshooting and Maintenance
Adhere to all the safety measures described throughout this manual. If the PV
system does not operate correctly, the following troubleshooting measures can
be applied by
qualified personnel.
8.1 LED Status Indications and Error Report
LED Startup:
The LED of each microinverter blinks red for a while at the beginning, and then
blinks green to indicate normal start-up approximately 10 seconds after DC
power is applied. If the LED blinks red after DC power is on, it indicates a failure
during the start-up.
Post-Startup LED Indications:
Check LED status to confirm the present situation.
Flashing Green: It indicates normal operation.
Flashing Red:
1. If red light flashes every 2 or 3 seconds, it indicates that the microinverter is
waiting for sun or prepare to produce energy.
2. If red light flashes continuously, it indicates that the microinverter is not
operating normally. The microinverter does not detect that the utility grid is
within operable voltage/frequency range. The microinverter cannot produce
power until this is solved.
8.2 Troubleshoot an Inoperable Microinverter
To troubleshoot an inoperable microinverter, follow the steps in the order shown
below.
WARNING: Be aware that only qualified personnel should troubleshoot the PV
array or the Envertech microinverter.
Ensure that all AC and DC wiring is correct. Ensure that none of
the AC and DC wires is twisted or damaged.
Do not attempt to repair the Envertech microinverter. It
contains no user-serviceable parts. If the microinverter fails,
contact your direct supplier or Envertech customer service to
obtain an RMA (return merchandise authorization) number and
start the replacement process.
