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 series energy storage integrated
machines. the PV string connected to the energy storage integrated
machine must adopt the DC connector configured especially for the
energy storage integrated machine, do not use other connection devices
without authorization from our company, otherwise damage to the device,
unstable operation or fire may occur, and our company will not undertake
quality assurance or assume any direct or joint liability thereof.
Note:
It is recommended to use 4mm
²
of 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 energy storage integrated machine 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 energy storage
integrated machine.
●
Ensure that the PV string polarity matches the PV connector, otherwise the energy
storage integrated machine 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 machine.
