WARNING!
Please do not connect more than one PV inverter to one AC circuit breaker.
WARNING!
A circuit breaker shall be installed between the PV inverter and public grid. In the event an
individual circuit breaker is used for N wire, please do not disconnect N wire before
disconnecting L wire, otherwise the PV inverter might be damaged.

Electrical Limitations
#
The maximum open-circuited voltage (V
oc
) of each PV string shall not exceed the Maximum
Working Voltage Range as specified in the table below.
#
The short-circuited current (
I
sc
) of the PV string should not exceed the Inverter’s permitted
maximum DC current as specified below.
