These are the maximum wire sizes that will fit the controller terminals.
CAUTION: When the PV modules connect in series, the open circuit
voltage of the PV array must not exceed 92V at 25

CAUTION: The wire size is only for reference. If there is a long distance between the
PV array and the controller or between the controller and the battery, larger wires can
be used to reduce the voltage drop and improve performance.
CAUTION: For the battery, the recommended wire will be selected
according to the conditions that its terminals are not connected to any
additional inverter.
2.4 Mounting
WARNING: Risk of explosion! Never install the controller in a sealed
enclose with flooded batteries! Do not install in a confined area where
battery gas can accumulate.
WARNING: Risk of electric shock! When wiring the solar modules, the PV
array can produce open circuit voltages in excess of 100V when in
sunlight.
