Grid-Tied Operation; Maintenance And Inspection - INVT iMars Operation Manual

iMars grid-tied solar inverters
 Do not put and install the inverter on or close to combustible materials.
 Keep the installation site away from children and other public places.
 Remove the metal jewelry such as ring and bracelet before installation and
electrical connection to avoid electric shock.
 Do cover solar modules with light-tight materials before electrical connection.
Exposed to sunlight, solar modules will output dangerous voltage.
 The inverter input voltage can not exceed the maximum input voltage; otherwise
inverter damage may occur.
 The positive and negative pole of solar modules can not be grounded, otherwise
irrecoverable damage may occur.
 Ensure the proper grounding of the inverter, otherwise, improper connection or
no grounding may cause stop of the inverter.
 Ensure reliable installation and electrical connection.
Note: iMars series grid-tied solar inverters are only for crystalline silicon solar modules.

1.2.2 Grid-tied operation

 Only qualified electricians are allowed to operate the inverter under the
permission of local power departments.
 All electrical connections must meet the electrical standards of the
countries/regions in which the project is located.
 Ensure reliable installation and electrical connection before operation.
 Do not open the cover of inverter during operation or voltage is present.

1.2.3 Maintenance and inspection

 Only qualified electricians are allowed to perform the maintenance, inspection,
and components replacement of the inverter.
 Contact with the local dealer or supplier for maintenance.
 In order to avoid irrelevant personnel from entering the maintenance area during
maintenance, temporary warning labels must be placed to warn
non-professionals to enter or use fence for isolation.
 Firstly disconnect all power supplies of the grid to the inverter before any
maintenance, and then disconnect the DC breakers and wait for at least 5
minutes until the inverter is discharged before maintenance.
 Please follow electrostatic protection norms and take correct protective
