Inverter states includes: wait, check, normal, fault and permanent
Wait:
Inverter is waiting to Check State when reconnect the system. In this state, grid voltage value is
between the max and min limits and so on; If not, inverter will go to Fault State or Permanent State.
Check:
Inverter is checking isolation resistor, relays, and other safety requirements. It also does self-test to
ensure inverter software and hardware are well functional. Inverter will go to Fault State or Permanent
State if any error or fault occurs.
Normal:
Inverter enter to Normal State
，
it is feeding power to the grid; inverter will go to Fault State or
Permanent state if any error or fault occurs.
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.
Permanent:
Inverter has encountered unrecoverable error, we need maintainer debug this kind of error
according to error code.
When the control board and communication board connection fails, the LCD display interface as shown in
the figure below.
