Dc Connection - Njoy Astris 5K/3P2T2 User Manual

Internal current detection equipment for inverter, the inverter detects the
leakage of the power grid that is greater than the reduced value, and will
be disconnected quickly from the power grid. If the external installation
leakage protection device is installed, Its action eletricity must be greater
than equal to 300mA.

5.3 DC Connection

DANGER
-PV modules generate electric energy when exposed to sunlight
and can create an electrical shock hazard. Therefore, when
connecting the PV modules, shield them with opaque cloth and
ensure that DC switches are OFF.
-To avoid electric shock, don't touch the charge part and connect
the terminals carefully.
-Before connecting power cables, ensure the AC/DC switches are
OFF.
-When the inverter is connected to the grid, don't plug in or plug
out the PV strings.
-Don't perform any operation until the inverter is shut down.
WARNING
-PV modules connected in series in each PV string must be of the
same specifications.
-The maximum open-circuit voltage of each PV string must be
always lower than or equal to its permitted range.
-The maximum short circuit current of each PV string must be
always lower than or equal to its permitted range.
-Ensure that the positive and negative terminals of each PV
strings connected to the inverter correctly.
-The positive or negative terminals of PV strings can't be
connected with short circuit.
-The total output power of all PV strings can't exceed the
maximum input power of the inverter.
