Inverter states includes: wait, check, normal and fault.
Inverter statuses include:
Wait:
the inverter is waiting for the control status at the end of the reconnection time. In this state, the PV
voltage must be higher than 250 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.
Check
: the inverter is checking the insulation resistance, relays and other safety requirements. It also runs a
self-test to ensure that the software and hardware of the inverter are functioning properly. The inverter
switches to the error state or permanent error state if an errors occur.
Normal
: The inverter is functioning normally and is feeding power into the grid; the inverter will go into a
permanent error state if any faults are found.
Fault:
Fault State: Inverter has encountered recoverable error. It should recover if the errors disappear. If
Fault State continues; please check the inverter according error code.
When the control board and communication board connection fail, the LCD display interface as shown in the
figure below.
