CAUTION!
Before installing and using the micro inverter, carefully read all operating
instructions and safety instructions (micro inverter, solar panel, etc.). Make
sure that you have understood everything. Consult a suitable specialist if you
are unsure.
CAUTION!
There is a risk of electric shock when installing this device.
CAUTION!
Do not touch live parts, including the connected solar panels, when the
system is connected to the electrical mains.
CAUTION!
Note that the housing of the micro inverter is the heat sink and can reach a
temperature of 80 °C. To reduce the risk of burns, do not touch the micro
inverter housing.
CAUTION!
The external protective grounding conductor is connected to the protective
grounding conductor terminal of the micro inverter via AC connection. When
connecting, connect the AC terminal first to ensure grounding of the micro
inverter. Then connect the DC terminals. When disconnecting, disconnect the
AC first by opening the branch circuit breaker but keeping the protective
grounding conductor in the branch circuit breaker connected to the micro
inverter. Then disconnect the DC inputs.
CAUTION!
Do not, under any circumstances, connect the DC input if the AC connection
is not connected.
CAUTION!
Install disconnect devices on the AC side of the micro inverter.
CAUTION!
It is strongly recommended to install surge protectors in the appropriate meter
box.
CAUTION!
You should not use an AC residual current device to protect the
corresponding circuit to the micro inverter, even if it is an outdoor circuit. None
of the small residual current devices (5~30 mA) are designed for regeneration
and will be damaged if regeneration occurs. The same is true for AC arc fault
circuit breakers. They are not evaluated for regenerative power and could be
damaged if regenerated with the output of a solar micro inverter.
The micro inverter is already pre-installed on a solar module in this set It may only be
necessary to connect the solar modules (DC) to the micro inverter. On the AC side,
only the connection with the enclosed connection cable must be made. A Wieland
plug connection is recommended here according to VDE. A Schuko plug connection
with a Schuko socket is also possible.
