Disconnecting the unit securely from the grid, the PV generators, and batteries by using DC and
AC breaker. The DC and AC breaker should be capable of disconnect all non-ground conductors
after installation.
PV Modules & Grounding Equipment
Capacitive Discharge Currents
Comply with the local requirements for grounding the PV modules and generator. We
recommend connecting the generator frame and other electrically conductive surfaces in a
way that ensures continuous conduction with ground, to provide optimal protection for the
system and people.
PV modules with a larger capacity than the ground, such as thin-film photovoltaic modules on
metal substrates, can only be used if their coupling capacity does not exceed 470nF. During
the charging and discharging operation, a leakage current will flow to the ground, and its
magnitude depends on the installation of the PV modules such as aluminum foil on a metal
roof) and the weather conditions (such as rain and snow). Generally, the leakage current
does not exceed 30mA. If it exceeds this range, the inverter will trigger protection and
automatically disconnect from the grid.
Do not attempt to open the device during operation!
