2. Factory Default. The manufacturer’s parameter default values can be
restored when the inverter is not in operation mode. Otherwise “Fault
Operated” will be reported.
3. ARC Detect. Manually begin an arc-fault test. The inverter will cease
power production and test ARC.
Arcing check and protection is mainly divided into two parts, the Arcing
check board is responsible for whether there is Arcing in line, and
transfer an Arc protection signal to the DSP in the dominating control
board. The control board DSP is responsible for disconnecting the
inverter from the grid after receiving the Arc protection signal to ensure
safety. The Arc board failure will cause ‘arc board err’ shown on the
LCD and it will not connect to the grid until the arc board is OK. If there
is an Arc fault, the LCD displays the fault which can only be cleared
manually.
4. ARC Clear. Manually clear the ARC fault. Move the cursor to this menu,
and press ENT. The operation result will appear on the LCD, ie.
“Succeed” or “Failed”. Complete this action after checking the PV
system for potential arcs and taking corrective action.
5. MPPT Scan. Manually execute the MPPT scan. Move the cursor to this
item and press the ENT key to initiate the scanning. The LCD screen
INSTRUCTION:
Force Restart is effective only when the faults “IntFault0010~0150” in
the troubleshooting table occur. The inverter may restore to normal
operation automatically if an Alarm or a Protection faults occur. This
function will not respond when the inverter is in operation mode and a
“FaultOperated” Alarm will be indicated on the LCD.
