NOTE:
1. The AFCI Function of the WIT Inverter is disabled by default. If you want to
enable the AFCI, please contact Growatt support.
2. Do not connect the Maximum Power Point Trackers (MPPTs) on the DC side in
parallel as it might trigger the AFCI mistakenly.
3.7.2 Clearing the Alarm
In the event that the WIT Inverter reports “Error 200” and the PV indicator turns
red, an arc fault might have been detected. Please perform the following steps to
clear the alarm.
Step 1: Disconnect the WIT inverter from all power sources. Turn off the battery
switch and the AC output circuit breaker, then turn the DC switches to the OFF
position. Wait until the error message disappears.
Fig 3.10
Step 2: Troubleshooting. Check if the open-circuit of all PV strings are within the
permissible range.
Step 3: After the fault is cleared, restart the inverter. Turn on the battery switch
and the AC breaker, and turn the DC switch to the ON position. Wait until the
system is working properly.

3.8 Anti-PID Function
PID (Potential Induced Degradation) typically occurs in PV systems where there is
a voltage potential between the solar cells and the grounded frame or other
conductive elements of the system. This potential difference, combined with high
humidity and temperature, can lead to leakage currents that degrade the
performance of the solar modules over time. The Anti-PID function integrated in
Growatt inverters can effectively reverse the PID effect by applying DC voltage to
the PV modules during nighttime, enhancing solar energy harvest and
performance.
If the WIT Inverter passes the AFCI self-test, it will work in the normal mode and
the PV indicator will be green. If it fails, the inverter will report “Error 425”. In this
case, please reboot the system and perform Step 1 to Step 3. If it failed again,
please disconnect all power sources and contact Growatt support.
