INSTALLATION:
CAUTION
• 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. In that case, larger wires shall
be used to reduce the voltage drop and improve the system
performance.
• The recommended wire for the battery is that its terminals
are not connected to any additional inverter.
MOUNTING
WARNING
• Risk of explosion! Never install the controller in a sealed
enclose with flooded batteries! Do not install the controller in
a confined area where battery gas can accumulate.
• Risk of electric shock! When wiring the solar modules, the PV
array can produce a high open-circuit voltage, so turn o the
breaker before wiring and be careful when wiring.
• Controllers have no battery reverse protection. Do not
reverse the battery during the wiring. Otherwise, the
controller may be damaged.
CAUTION
The controller requires at least 150mm of clearance above and
below for proper airflow. Ventilation is highly recommended if
mounted in an enclosure.
Installation procedures:
Step 1: Determine the installation location and heat-dissipation space
