Inverter states includes: wait、check、normal、fault and permanent
Wait
：
Inverter is waiting to Check State at the end of reconnection time. In this state, the
PV voltage is more than 250V, 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 functional. Inverter will go to
Fault State or Permanent State if any error or fault occurs.
：
Normal
Inverter enter to Normal State
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
：
kind of error according to error information.
When the control board and communication board connection fails, the LCD display interface
as shown in the figure below.
