5. Function
Operation Mode
【
standby Mode
】
The standby mode means that the inverter is ready for operation but still not connected to the grid. In this mode, it
will continue to check whether PV array has enough power to feedback into grid. When the inverter passes dump
load test after startup, it will change from standby mode to Checking mode.
【
Checking Mode
】
If inverter passes dump load test and no error/fault occurs, will start checking mode to deliver power.
【
On-grid Mode
】
In this mode, series inverters convert PV array’s DC into AC and feedback into grid.
