In the Read/Write Register section it is possible to access the following sub-menus:

"Power On/Off" menu: Manual Turn ON/OFF: Manual Power ON/OFF is required after regulation setting or manual
(fault) shut-down.

"ForceRestart" menu: If a fault shutdown happens, a severe fault may have occurred inside the inverter. The user
can perform a forced reboot for one time per Power on in this menu if the user needs to restart the inverter.

"FactoryDefaults" menu: The manufacturer's parameter default values can be restored when the inverter is not in
operation mode. Otherwise "Fault Operated" will be reported.

"MPPTScan" menu: "MPPTScan" is used to execute the MPPT scanning manually. The device screen will skip to
normal operation interface if the MPPT scanning succeeds or remain on the "MPPTScan menu" interface if the
scanning fails. MPPT scan function is used for multi-MPP tracking, and is useful if the PV modules are partly
shadowed or installed with different angles. The factory setting of MPPT scan is Enabled, yet can also be set to
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 the following conditions ：
The total input power is lower than 90% of the active power.
Once this MPPT scan function is activated on the device, it will search the maximum power point at a voltage step of 5V
in the MPPT range for full load, and retrieve the maximum power point.

"ARCDetect" menu: Execute the "ARC Detect", the inverter will stop operating 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 Arcing protection signal to the DSP in the dominating control board. The control board DSP is
responsible for the control of inverter off the grid after receiving Arcing signal to ensure safety. The Arcing board
failure will cause "ARC board err" shown on the device and it will not connect to the grid until the arc board is OK. If
there is Arcing fault, the device displays the fault which can only be cleared manually.

"ArcClear" is used to clear the ARC fault. The operation result will appear on the Device, ie. "Succeed" or "Failed".
