● The power meter and the Smart Dongle must be connected to the same inverter.
● In the preceding networking, the inverters are cascaded and support the grid-tied
point control function to achieve zero export.
● If the inverters require the grid-tied point control function, they need to be
connected to a power meter.
● EMMA networking

Requirements for Signal Cables
● Ensure that the protection layer of the cable is in the connector. The surplus
core should be cut o from the protection layer.
● Ensure that the exposed core is totally inserted into the cable hole.
● Ensure that the signal cables are connected securely.
● Ensure that the cables are not twisted.
● If multiple signal cables need to be connected to a single connector, ensure
that the outer diameters of the signal cables are the same.
