penetrating the anodized coating of the aluminum frame (see the pictures below). Recommended
Pan head tapping screws with cross recessed torque is 1 N•m.
Electrical installation
•
Any hardware used must be compatible with the mounting structure material to avoid galvanic
corrosion.
•
It is not recommended to use eArche with different configurations in the same system.
•
Excessive cables must be organized or fixed in an adequate way, e.g. attached to the mounting
structure by using non-metallic cable ties.
•
For applications requiring high operating voltage several eArche can be connected in series to form a
string of eArche; the system voltage is then equal to the sum of the voltage of each eArche.
•
For applications requiring high operating currents several strings of eArche can be connected in
parallel; the system current is then equal to the sum of the current of each string of eArche.
•
The maximum system voltage is 1000 volts DC.
•
The maximum number of series connected eArche depends on system design, the type of inverter
used and environmental conditions.
•
Please make sure no more than two strings in parallel if eArche without any fuse or blocking diode to
be connected according to the maximum series fuse rating of eArche and local electrical installation
code.
•
There is no limitation on the number of eArche that can be connected in parallel (fuse for each string
should be considered), the number of eArche is determined by system design parameters such as
current or power output.
•
To prevent the cables and the connectors from overheating, the cross section of the cables and the
capacity of the connectors must be selected to suit the maximum system short circuit current. The
recommended cable is PV wire(temperature rating is 90
℃
) with a cross section of at least 2.5mm².
•
Please refer to local regulations to determine the system wires size, type and temperature.
•
eArche are supplied with connectors to be used for system electrical connections. The recommended
connectors are Multi Contact MC4, TL-Cable01 or equivalent, of which TL-Cable01 and Multi Contact
MC4 are connectable.
•
To ensure reliable electric connection and to prevent possible intrusion of humidity, Multi Contact
MC4 connectors and TL-Cable01 connectors must be mated and locked together until a click can be
heard.
•
Long-term exposure to wet environments may cause connectors’ poor connectivity, resulting in
current leakage and poor conductivity. SUNMAN recommend proper connector/cable/wire
management to prevent moisture intrusion. Depending on the amount of humidity, SUNMAN
