User Manual
● Before turning on the AC switch between the inverter and the power grid,
check that the AC voltage is within the specified range using a multimeter.
● If the inverter has not been running for more than half a year after being
mounted, it must be checked and tested by professionals before being put into
operation.
● When powering on the system, you must switch on DC SWITCH 1 first, and
then switch on DC SWITCH 2 and DC SWITCH 3 after LED 1 is steady on.
Huawei shall not be held liable for damages caused by failing to follow this
sequence.
● The DC switches support automatic disconnection. Reverse polarity or improper
PV module configuration will trigger automatic disconnection of DC switches.
In this case, do not forcibly turn on the switches before the faults are fixed.
Otherwise, damages caused by the forced switch-on will not be covered under
any warranty.
● When the handle of the DC switch points to the
DC switch is in released state and the switch is not completely connected. In
this case, automatic disconnection may fail. You need to set the DC switch to
the ON position.
● When the system is powered on or running, do not place obstacles (such as
cables) to block the rotation of the handle or manually hold the handle.
Otherwise, the DC switch cannot be automatically disconnected.
