5. Install four user-supplied fasteners through the four mounting holes in the controller and into the
mounting surface.
6. Tighten all the fasteners to ensure the controller cannot slide in any direction.
IMPORTANT:
For best results, mount the charge controller and batteries as close to the panels as practical.

ONNECTIONS
WARNING:
Loose connectors result in excessive voltage drop and may over heat wires, which can cause
the wire insulation to melt. This can cause electrical fires. Verify all connections are secure and have no
voltage drop.
IMPORTANT:
The NEC requires that the wires carrying the system current never exceed 80% of the
conductor’s current rating (sizing recommendations are located in Section 4).
IMPORTANT:
The screw-down terminals on the charge controller accept 6~26AWG wire.
IMPORTANT:
Strip the wire ends
approximately 0.3” (7.6mm) before connecting to the charge controller.
Use caution when handling the stripped wires to avoid electric shock.
1) Connect the Battery
Connect the charge controller to the battery BEFORE connecting the solar panels to the charge controller.
Insert the battery wiring into the BATTERY terminals on the back of the charge controller and tighten the
terminals from the top of the terminal block using a screwdriver to ensure a good connection is made. Be
sure to note the polarity of each terminal; the charge controller self-protection feature will prevent damage
from reverse polarity connections, but the charge controller will not function until the battery is connected
properly.
A 30-amp fuse is recommended in the positive wire connecting the charge controller to the battery; See
Section 3.5 for a complete fusing diagram.
2) Connect the Solar Panel (PV) Array
Insert the solar panel wiring to the SOLAR terminals on the back of the charge controller and tighten the
terminals from the top of the terminal block using a screwdriver to ensure a good connection is made. Be
sure to note the polarity of each terminal; the charge controller self-protection feature will prevent damage
from reverse polarity connections, but the charge controller will not function until the PV Array is connected
properly.
