3. he units should flash red one minute after the AC circuit breaker is switched on. Then the
blue LED flashes. This means that the units are generating power normally. The faster the
blue LED flashes, the more power is being generated.
4. Configure the internal WiFi module according to the instruction manual.
5. The microinverters will start sending performance data to the network via the Wi-Fi module
every 5 minutes. This allows customers to monitor the performance data of each
microinverter via the website and the APP.
NOTE: When AC power is present but the microinverter is not operating, approximately 0.1 A of
current and 25 VA (W) of power can be measured for each microinverter with a
power meter. This power is reactive power that is not consumed by the utility
grid.
Troubleshooting
Qualified personnel can perform the following troubleshooting steps if the PV system is not
functioning properly:
Status displays and error messages
Flashes slowly blue
Flashes quickly blue
Flashes red
Flashes red twice
Flashes red three times
- Generates low power
- Generates high power
- no power
- AC undervoltage or high voltage
- Mains fault
Start-LED
One minute after the first application of DC voltage to the microinverter, a short red flash
indicates a successful start-up sequence of the microinverter. An equal or greater short
red flash after the first application of DC voltage to the microinverter indicates a
microinverter setup error.
