Item List Parameter Input Value e.g.
01.V PV 1 PV1 voltage 650.0
05.V PV 2 PV2 voltage 650.0
Note: PV1 stands for MPP tracker A, PV2 stands for MPP tracker B.

5) Select “05.V PV 2” in Item List dropdown list and repeat above processes to finish PV2
voltage calibration.
Residual I High
Leakage current is too high.
1. When inverter showing Residual I High, please restart the inverter for 2 or 3 times.
2. If the error still exists, please examine if the live and neutral (L1, L2, L3 and N) are connected
well.

3. If the live and neutral (L and N) are ok but the error still exists, please replace an inverter.
Output High DCI
Output DC current too high; The DC offset in the alternating output current is detected too high.
1. Please restart the inverter and check whether the fault still exists or not. If the fault doesn’t
always appear, please don’t care because the inverter will automatically recover and continue
working.
2. If the error always appears, please update the firmware of control board to version 0D36 or
above, and COM board to version 0C29 or above.
3. If the error still exits after updating, please contact Growatt service to replace an inverter.
