When "Group" is selected as the debuggi ng mode, the operation mode is group
control.
Long press the "ON/OFF" key ON the inverter panel for 3 seconds, the "RUN"
light will always be ON after flashing, the inverter will start to RUN, and the
system will work (if the load is single -phase pump running for the first time,
select "Yes" after motor parameter detection, and the inverter will start to
RUN).At this point, it is necessary to check whether the photovoltaic pump
system is working normally and whether it can reach the head and flow of the
system .After running for a period of time, press the "ON/OFF" key ON the LCD
panel of the inverter to stop the inverter and turn OFF the "RUN" light.
Disconnect the DC input of the PHOTOVOLTAIC array, connect the AC input,
