At start up, the LCD screen displays “ZCS INNOVATION...,” as shown in the figure below, when the control
board is correctly connected to the communication board, the LCD display will show the current status of
the inverter, as shown in the figure below.
Inverter statuses include:
Wait:
the inverter is waiting for the control status at the end of the reconnection time. In this status, the PV
voltage must be higher than 100 V, the grid voltage value must be between the minimum and maximum
permissible limits, as should the other grid parameters; otherwise, the inverter will go into an error state.
Control:
the inverter is checking the insulation resistance, relays and other safety parameters. It also runs a
self-test to ensure that the software and hardware of the inverter are functioning properly. The inverter will
go to an error state if any faults or anomalies are found.
Normal
: the inverter is functioning properly and is feeding power into the grid. If any faults are found, the
inverter will go into an error state.
Error:
the inverter has encountered a non-permanent error. If the error disappears on its own, the inverter
will return to its normal state. If the error continues, please check the error code.
