Micro Inverter System Operating Instructions

To operate the Micro Inverter PV system:

1. Turn ON the AC circuit breaker on each Micro Inverter AC branch circuit.

2. Turn ON the main utility-grid AC circuit breaker. Your system will start producing power after a one-minute waiting time.

3. The units should start blinking red one minutes after turning on the AC circuit breaker.
   Then blue led blinking. This means they are producing power normally, the faster blinking of the blue led means more power generated.

4. Configure the internal wifi module according to its user manual.

5. The Microinverters will start to send performance data over wifi module to the network every 5 minutes.It enables customers to monitor performance data of each Micro Inverter through website and APP.

When AC power is applied but the Micro Inverter not started up, about 0.1 A current and 25VA power for each Micro Inverter may be measured by a power meter. This power is reactive power,not consume from utility grid.

Troubleshooting

Qualified personnel can use the following troubleshooting steps if the PV system does not operate correctly:

Status Indications and Error Reporting
Start up LED
One minute after DC power is first applied to the Micro Inverter,one short red blinks indicate a successful Micro Inverter startup sequence, be equal or greater than two short red blinks after DC power is first applied to the Micro Inverter indicate a failure during Micro Inverter setup.

Operation LED

GFDI Error
A four time red LED indicates the Micro Inverter has detected a Ground Fault Detector Interrupter (GFDI) error in the PV system.
Unless the GFDI error has been cleared, the LED will remain four times blinking.
