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
and tracking control box
● Fuse specifications: rated voltage ≥
500 V; rated current: 16 A;
protection: gG
● Circuit breaker specifications: rated
voltage ≥ 500 V; rated current: 16 A;
tripping: C
To ensure that the inverter can be
safely disconnected from the power grid
when an exception occurs, connect an
AC switch to the AC side of the inverter.
Select an appropriate AC switch in
accordance with local industry
standards and regulations. Huawei
recommends the following switch
specifications:
● Installed in the AC combiner box
● Recommended: a three-phase AC
circuit breaker with a rated voltage
greater than or equal to 500 V AC
and a rated current of 250 A
The solar inverter communicates with
the management system through the
SDongle.
