PV connection
Only qualified PV strings under the local electrical safety laws and
regulations and comply with the technical parameters of this manual are
allowed to connect to the Soluna S8 EU-A50. The PV string connected to
the BESS must adopt the DC connector configured for the BESS. Do not
use other connection devices without authorization from our company;
otherwise, damage to the equipment, unstable operation or fire may
occur, and Soluna will not undertake quality assurance or assume any
direct or joint liability thereof.
Note:
It is recommended to use 4mm wire for PV connecting wire.
PV terminal crimping - Terminal crimping torque 3.6
–
4.6 N.m.
•
Ensure that the maximum open-circuit voltage of each PV string is not higher
than the maximum input voltage of the BESS under any circumstances.
•
It is forbidden to connect the PE wire (ground wire) to the positive and
negative poles of the PV strings; otherwise, it will cause damage to the
BESS .
•
Ensure that the PV string polarity matches the PV connector; otherwise, the
BESS will be damaged.
•
The insulation resistance of the PV panel to the ground should be greater than
the safety regulation; otherwise, there will be electrical hazards.
•
Ensure the wires of the cable correspond to the connector terminals, and
tighten the screws. The crimping torque of the screws is 1.5
–
2.5 N.m.
•
Use a multimeter to measure the voltage of the DC input string, verify the
polarity of the DC input cable, and ensure that the voltage of each string is
within the allowable range of the system.
