PV modules generate electric energy when exposed to sunlight and can create an
electrical shock hazard. Therefore, when connecting the PV modules, shield them
with opaque cloth and ensure that DC switches are OFF. To avoid electric shock,
don't touch the charge part and connect the terminals carefully.
Before connecting power cables, ensure the AC/DC switches are OFF.
When the inverter is connected to the grid, don't plug in or plug out the PV strings.
Don't perform any operation until the inverter is shut down.
PV modules connected in series in each PV string must be of the same specifications.
The maximum open-circuit voltage of each PV string must be always lower
than or equal to its permitted range.
The maximum short circuit current of each PV string must be always lower
than or equal to its permitted range.
Ensure that the positive and negative terminals of each PV strings connected to the
inverter correctly.
The positive or negative terminals of PV strings can't be connected with short circuit.
The total output power of all PV strings can't exceed the maximum input power of
the inverter.
The positive and negative terminals of PV modules can't connect to PE wire (GND),
otherwise, the inverter will be damaged.
Ensure that the voltage of each PV string doesn't exceed 1100V under any
circumstances.
When the input voltage is 1000V to 1100V, the inverter will enter the standby state.
When the voltage returns to the MPPT operating voltage, namely 160V-1000V, the
inverter will return to the normal state.
