The wire size is only for reference. Suppose a long distance exists
between the PV array and the controller or between the controller
and the battery. Larger size wires can be used to reduce the
voltage drop and improve performance.
The battery cable size recommendations assume that the charge
controller is the only device connected to this cable (no inverter
connected to the same cable etc.).
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.
Risk of electric shock. Disconnect the breaker before wiring
because the PV array may generate a high open-circuit voltage.
The controller requires at least 150mm of clearance above and
below for proper airflow. Ventilation is highly recommended if
mounted in an enclosure.
