F R is effective only when the faults "IntFault0010~0150" in the troubleshooting table occur. The
ORCE ESTART
inverter may restore to normal operation automatically if alarm or 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.

is not in operation mode. If you try to change the parameters while the unit is operational. Otherwise
"Fault Operated" will be displayed.
(3) ARC D In the
ETECT
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
detecting if there is arcing in the PV line, and sends the arcing protection signal to the DSP in the control
board. The control board "DSP" is responsible for disconnecting the inverter from the grid after receiving
the arcing signal to ensure safety. The arcing 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 Arcing fault, the LCD displays the
fault which can only be cleared manually.
ARC C
(4) is used to clear the ARC fault. Move the cursor to this menu, and press ENT. The operation
LEAR
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 S menu: is to execute the MPPT scanning manually. Move the cursor to this item, and press
CAN
ENT to initiate the scanning. The LCD screen will skip to normal operation interface if the MPPT scanning
succeeds, or remain on the
MPPT scan function is used for multi-MPP tracking, if the PV panels are partly shadowed or installed
with different angle. The factory default setting of MPPT scan is "Enabled", and it can also be Disabled.
When the MPPT scan function is enabled, the scan period is 60 minutes; the inverter will scan the
maximum power point in the MPPT range, according to below condition:
In independent mode (3 MPPTs), each input power must be lower than 75% of the rated power of each
MPPT tracker.
