• 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.
• 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.
• Do not remove Solarlok SAFE-TE Connectors of unused PV input terminal. Failing to do so
may result in electric shocks.
• 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.
