Description
Implements power control at the grid-
tied point in low voltage scenarios
using a power meter.
Adjusts the angle of the supports.
The tracking system should be
equipped with an overcurrent
protection device or component. The
power cable between the device or
component and the wiring terminal
should be no longer than 2.5 m.
Therefore, a fuse or a circuit breaker is
recommended.
● Installed between the solar inverter
● Fuse specifications: rated voltage ≥
● Circuit breaker specifications: rated
● Installed in the AC combiner box
● Recommended: a three-phase AC
The solar inverter communicates with
the management system through the
SDongle.
NO TICE

● The cable size must comply with local cable standards.
● The factors that affect cable selection include the rated current, cable type, routing
mode, ambient temperature, and maximum expected line loss.
● If MBUS is used for communication, you are advised to use multi-core cables with the
maximum communication distance of 1000 m. To use other types of AC power cables,
contact local technical support.
