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.
