W04

W05

Grid_phase_warn

1. Check the phase sequence connection of the power grid.

2. Try to change the grid type, 0, 240/120.

3. If there is still no solution to check the wiring at the grid

end.

Check whether the arrow on CT's case point to the inverter or

not , and check if the installation location of CTs are correct.

Description Solutions

F01 DC_Inversed_Failure

Check the PV input polarity.

F02 DC_Insulation_Failure

Check whether the PV is grounded, secondly, check whether

the impedance of the PV to the ground is normal.

F03 GFDI_Failure

1.Check whether the PV modules are grounded.

2. Check whether the impedance of the PV to the ground is

normal, whether there is leakage current.
