• Ensure that the PE cable is connected securely.

• In order to avoid malfunction, please do not connect any PV modules that have a risk of leakage current
to the inverter.
• In order to avoid lightning damage to the inverter, it is recommended to add a surge protection switch at
the PV junction box.
• The same number of series-connected PV modules must be connected to each string.
• After the positive and negative connectors snap into place, slightly pull the PV input cables back to
ensure that they are connected securely.
• It is not recommended that connect different brands or models of PV modules to one MPPT circuit, or
connect PV modules of different orientation or angles to one PV string.

• Before connecting the PV input cables, ensure AC switch connected to the inverter and the PV SWITCH
on the inverter are OFF. Failing to do so may result in electric shocks.
• The PV string will generate lethal high voltage when exposed to sunlight. Disconnect the PV cable of PV
string before connecting DC power.
• Before connection, ensure the polarity of the output of the PV array matches "PV+"/"PV-" symbols.
• Before connecting the PV input cables, ensure that the impedance between the positive/negative terminals
of the PV string and earth are larger than 1 MΩ. Do not ground the PV array positive/negative hole.
• When the inverter is running, it is not allowed to work on the PV input cables, such as connecting or
disconnecting a PV string or a PV module in a PV string. Failing to do so may cause electric shocks.
• If no PV string connects to a PV input terminal of the inverter, do not remove the protective cap from the
PV input terminal. Otherwise, the IP rating of the inverter will be affected.
• Ensure that the maximum DC voltage and the maximum short-circuit current of any string do not exceed
the allowed range specified in the "Technical Parameters" of the User Manual.
