ATTENTION
On-grid operation
 After connecting the external terminals of the inverter,
the recommended power-up sequence is: first turn on
the battery, then turn on DC, then connect to the grid,
and finally connect the load.
 After connecting the external terminals of the inverter,
the recommended de-energizing sequence is: first
disconnect the load, then disconnect DC, then
disconnect the battery, and finally disconnect the grid.
NOTE
 The open-circuit voltage of the modules connected in
series must be lower than or equal to 1000 V.
The connected PV modules must be compliant with IEC 61730

The DVC (decisive voltage classification) is the circuit voltage
which constantly occurs between two arbitrary live parts during
proper use in a worst-case scenario:
