Charger-Only
● The PV Power Preferred mode is not supported in charger-only scenarios.
● To implement dynamic charging power, a meter needs to be congured. The
meter can be directly connected to the charger through the FE port or
connected to the charger through a router.
● When the charger is connected to the router through WiFi, ensure that the
WiFi signal is good and there is no obstacle around the devices. Otherwise,
the meter may be disconnected and dynamic charging power cannot be
implemented.
