A three-phase AC switch should be installed on the AC side of the solar
inverter. To ensure that the solar inverter can safely disconnect itself from the
power grid when an exception occurs, select a proper overcurrent protection
device in compliance with local power distribution regulations.
Connect the AC output power cable according to the requirements specified
by local power grid operators.
Connect the power cable of the tracking system before the AC output power
cable. Otherwise, reworking will be caused.
