6.2.2 Grid Connection
The connection procedure will vary depending on the grid configuration.
CAUTION!
The installer is responsible for providing overcurrent protection.
To reduce the risk of fire, only connect to a circuit provided with
a
maximum branch-circuit overcurrent protection in
40 A
accordance with the National Electrical Code, ANSI/NFPA 70.

The AC circuit breaker (not included in the A1-HYB-G2 inverter) is required to
protect each AC line (L1 and L2) of the HYB series inverter. The circuit breaker
should be able to handle the rated maximum output voltage and current of the
inverter.

The following diagram provides an overview of the compatible grid configurations
of which voltage limit, frequency limit and conductors have to be connected to the
inverter to comply with the grid configuration.
Refer to the table below to determine the specific circuit breaker in order to avoid
potential fire hazards. The AC circuit breaker selection and installation must follow
the National Electrical Code(NEC), ANSI/NFPA 70 or local electrical codes.
