Alternatively, LED sequences could be an indicator of microinverters status (see section 6.1) Once the ECU has been commissioned properly, the APsystems Microinverters will start to send performance data to the ECU. The time required for all of the Microinverters in the system to report to the ECU will vary depending on the number of Microinverters in the system. -
Page 17: Troubleshooting
Please contact your local APsystems Technical Support. 6.2 ECU_APP APsystems ECU_APP (available in the EMA Manager APP) is the recommended tool to do on-site troubleshooting. When connecting the ECU_APP to the ECU hotspot (please check ECU User Manual for more detailed information), installer can check every microinverter status (production, communication) but also ZigBee signal strength, grid profile and other insightful data helping the troubleshooting. -
