lowest temperature and maximum irradiation can not exceed the module specified maximum
system voltage DC1000V. The reference formula of maximum quantity in series is
1000V/(1.25*Voc). The reference formula of maximum quantity in parallel is max protective
current/Isc+1(the maximum protective current of Jinyuan junction box is 15A)
The over-current protection of module is used on the DC side. Please refer to the local
regulations to make sure the fuse application requirement. If there may be a reverse current
through the module which exceeds the maximum fuse current, an equivalent over-current
protection will be needed to protect the module. If the number of parallel is equal or greater than
2 strings, every string of modules should be installed with an over-current protection device.
Please choose the dimension, type and temperature requirement of cable according to the
standards of local, regional and host country. To avoid the cable and connector overheated, the
cable conductivity and connector endurance should meet the short circuit current and
temperature when the system is exposed outdoor. Jinyuan suggests that the connect cable on
site should satisfy the module to be used under the module maximum short circuit current. The
cable should be a waterproof and UV-proof cable complying with the photovoltaic DC
requirement, with sectional area 4mm
connector is MC4 port, with male and female connectors distinguishing positive and negative
poles, which should be connected accordingly. When connecting with a third party matched
wiring device, follow the operating manual of the equipment manufacturer. Please make sure
the connector is clean,dry, in place and firm when connecting. Wrong connection or not in place
may cause a voltaic arc or electric shock. Connector should not subjected to additional pressure.
Non-professionals are prohibited to open the lock nut. The connector is only for connecting
circuit without opening or closing circuit function.
