When complex shading exits, double wave MPPT function may be used.
Turn on the D_Wave Switch, set the scan interval time(interval-T), save and send.
The inverter will carry out double wave MPPT scanning 1 time every scan interval time.

DRM is used to control the AC output of the inverter according to different state standards.
DRM default setting is “OFF”. If DRM setting is “ON”, but the inverter logic interface is not
connected to the switch or the switch is open, the inverter will display “Limit by DRM” and
the inverter output power will be limited to zero.
6.5.9.1 DRM Settings
The function is used to set the grid side relay state when the inverter AC output power is set
to 0% . Select enable to disconnect the inverter from the grid, select disable to keep the
inverter connected with the grid.
