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. Mannually 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. Mannually 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. Mannually execute the MPPT scan. Move the
cursor to this item, and press the ENT key to initiate the
scanning. The LCD screen will skip to normal operation
interface if the MPPT scanning succeeds, or remain on the
MPPT Scan menu interface if the scanning fails.
The factory default setting for "MPPTScan" is set to
<Enabled, yet can also be set to Disabled. When the MPPT
scan function is enabled, the default scan period is every 60
