7.1 Debug Inverter

1） Close the DC switch on the inverter. As long as the input DC voltage is greater than 250V, the inverter display will
display the following message: If there is no mains connection error, the inverter LED will turn red. If other information is
displayed, please refer to Chapter 9. If the debugging process encounters an unsolvable problem, please contact customer
service and perform the next step.
2） Close the circuit breaker or switch between the inverter and the grid. The inverter starts the self-test countdown. After the
self-test is normal, it will be connected to the grid.
3）In normal operation, the leaves of the inverter indication window will turn green.
4) Complete debugging.
If the inverter is stored over one month, its default time and date may looks wrong, the time
and date should be reset before connection to the grid.

communication address can be used directly. Note: The inverter communication address can be set from 1 to 254.
