The function is used for update the DSP.
This function is applicable by maintenance personnel only, wrong operation
will prevent the inverter from reaching maximum power.

This setting is used for grid operators, do not change this setting unless
specifically instructed to.
This function is used to calibrate inverter output energy and voltage. It will not impact the

Canadian Solar Three Phase Inverter does not require any regular maintenance. However,
cleaning the dust on heat-sink will help the inverter to dissipate the heat and increase its life
time. The dust can be removed with a soft brush.
7.1 Anti-PID Function
Inverter integrates optional Anti-PID module and it can recover
the PID effect during night thus protect the PV system from degradation.

CAUTION:
Do not touch the inverter's surface when it is operating. Some parts of the
inverter may be hot and cause burns. Turn off the inverter (refer to Section
6.2) and wait for a cool-down period before before any maintenance or
cleaning operation.
The LCD and the LED status indicator lights can be cleaned with a damp cloth if they are too
dirty to be read.
NOTE:
Never use any solvents, abrasives or corrosive materials to clean the inverter.
WARNING
:
The PID function is automatic. When the DC bus voltage is lower than 260Vdc,
the PID module will start creating 650 Vdc between PV- and ground.
No need any control or settings
The Anti-PID module repairs the PID effect of the PV model at night. When operating,
the inverter LCD screen displays " PID-repairing " information, and the red light is on.
The Anti-PID function is always ON when AC is applied.
If maintenance is required and turn off the AC switch can disable the Anti-PID function.
