Step 5:
Set the communication address and communication baud rate in the
communication setting interface. When the meter is used as Grid meter (DC,
AC/Hybrid system), the address is set to “005”. When it is used as the PV meter
(AC/Hybrid system), the address is set to “006”. The baud rate is set to 9600.

PV Connection
Please ensure the follows before connecting PV strings to the SMILE5-INV:
Make sure the open voltage of the PV strings will not exceed the max. DC input
voltage (600Vdc). Violating this condition will void the warranty.
Make sure the polarity of the PV connectors is correct.
Make sure the PV-switch, breakers of battery, AC-BACKUP and AC-Grid are all in
their off-states.
Make sure the PV resistance to ground is higher than 200KOhms.
The inverter uses the Vaconn D4 PV connectors. Please follow the picture below to
assemble the PV connectors.
PV conductor cross section requirements: 4~6 mm
