Remarks Description
The Smart Dongle has no
SIM card or the SIM card is
in poor contact. Check
whether the SIM card has
been installed or is in good
contact. If not, install a SIM
card or remove and re-
insert the SIM card.
The Smart Dongle fails to
be connected to a
management system
because the SIM card has
poor or no reception, or has
run out of mobile data. If
the Smart Dongle is reliably
connected, check the SIM
card connectivity through
the app. If you have poor or
no reception, contact the
carrier. Check whether the
tariff and mobile data plan
of the SIM card are
adequate. If not, ensure
sufficient balance in the
SIM card or purchase a data
package.
No communication with the
inverter:
– Remove and then insert
the Smart Dongle.
– Check whether the
inverter matches the
Smart Dongle.
– Connect the Smart
Dongle to another
inverter.
Check whether the
Smart Dongle is faulty or
the USB port of the
inverter is faulty.
