According to the diagram, put the CT of the supply grid balance on the L line of the family main line. The
1.
direction of the arrow on CT must be the same as that of the arrow shown in the diagram, the red line of CT is
positive 2, and the black line is negative 1. press it to the matching terminal CT1.( Pay attention to check that
the CT interface base on PCB is marked with CT1.)
According to the diagram, the CT of the solar balanced load is sheathed on the L line of the inverter output
2.
AC 230V. The direction of the arrow on the CT must be the same as that of the arrow shown in the diagram,
the red line of CT is positive 4 and the black line is negative 3, press it to the matching terminal CT2. (Pay
