of the AC switchis determined by the load capacity. The AC switch we recommend to connect to
the inverter output refer to Table 5.2.

The SUN limiter will measure the voltage and current of three phases separately, and this manual
(1) Connect SUN limiter to the grid. Connected to the grid is to measure the voltage of grid. Before
(2) Connect SUN limiter to clamp senor. Clamp senor can measure the current of the AC side, it
Only when the SUN limiter collects the voltage and current of the same phase can it judge the
power of the phase. So the clamp senor should be connected to the same phase as the before.
Open the side buckle of the clamp senor, then clamp the senor to the AC line on the DC switch,
(shown as below), and the white line corresponds to K terminal, black line corresponds to L
terminal. Connect the white line to the L1(L) and L1(K) terminal refer to the line mark of the SUN
