If the Datalogger is showing no Green or Red LED and the Inverter is offline but the 'Normal' LED is lit and the System Power Flow appears to be showing correct information for Grid, Load, PV and Battery etc then this could be one of two issues.
1. The Datalogger is faulty. To check and confirm, remove the suspect Datalogger and replace with a new (or known working) Datalogger. If the LED's come on then follow instructions in your Datalogger User Manual to connect the replacement Datalogger to the local wifi network. Then Unbind the original Datalogger from the Plant and add the new Datalogger to your Plant. You will need the new Datalogger Serial Number and Key in order to 'Add Gateway' to your existing Plant.
If you do not have a second Datalogger available then Installers can follow step 2 below to check if the 12V dc voltage to the Datalogger is present.
2. If you have tried a second Datalogger and there are still no Green or Red LED showing then there may be no power to the Datalogger from the Inverter.
Installers and competent electricians can follow these simple steps to confirm if 12V DC voltage to the Datalogger is present. The Voltage to the Datalogger is via Pins 5 (GND) and 9 (+12V) of the DB9 serial port socket of the Inverter that the Datalogger is plugged into. As per the DB9 Pin Out Diagram below please use a Digital Meter on DC Volts to measure for 12V dc between these pins.
If there is no voltage on pins 5 and 9 please contact Sunsynk 3rd Line Support for further instructions and guidance on how to restore power to your Datalogger.
