● The DTSU666-HW and YDS60-80 power meters support a maximum current of 80 A.
● If the SUN2000-(2KTL-6KTL)-L1 are cascaded with three-phase inverters, they must be
connected to the grid in the same phase.
● For a three-phase three-wire system, you need to set the cable connection mode.
Otherwise, the displayed voltage is incorrect.
● Ensure that the baud rates of the DTSU666-H, YDS60-C24, DTSU71 and DHSU1079-CT
meters are set to the default values. If they are changed, meters may go oine,
generate alarms, or aect the inverter output power.
