Fault
Regular error state
Permanent
Unrecoverable error state
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 180V, 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
，
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.
