7704 Contactor error at the DC disconnection
point.
30 s A ‒ • When disconnecting the
inverter from voltage sources,
check that all motor-driven
circuit breaker switches are set
to the OFF position. If the
switches are not all set to the
OFF position, set all the
switches to the OFF position
(see the Sunny Central
installation manual).
• Contact the SMA Service Line.
