5.6 Connecting an AC Output Power Cable
Prerequisites
● 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.
● Connect the AC output power cable according to the requirements
specied
by local power grid operators.
● Connect the power cable of the tracking system before the AC output power
cable. Otherwise, reworking will be caused.

● Do not connect loads between the inverter and the AC switch that directly
connects to the inverter. Otherwise, the switch may trip by mistake.
● If an AC switch is used with specications beyond local standards, regulations,
or the Company's recommendations, the switch may fail to turn o in a timely
manner in case of exceptions, causing serious faults.
Each inverter must be equipped with an AC output switch. Multiple inverters
cannot connect to the same AC output switch.
